Cross Reference to Related Applications

The present application claims priority from U.S. provisional patent application Ser. No.63/146,461, filed on 5/2/2021, and U.S. patent application Ser. No.17/545,433, filed on 8/12/2021, which are incorporated herein by reference in their entireties for all purposes.

Background

Typical beverage dispensing systems combine a diluent (e.g., water) with a base beverage ingredient (such as a concentrate or syrup made up of a variety of other ingredients). However, these base beverage ingredients often require considerable storage space and may even need to be kept refrigerated to prevent spoilage. Thus, these basic beverage ingredients are not typically stored in the beverage dispensing system, or even in the same room as the beverage dispensing system. In addition, each beverage may require its own unique base beverage ingredient, further increasing the storage space and overall footprint of the beverage dispensing system. Furthermore, typical beverage dispensing systems often do not allow for a high level of taste customization by the end user, as in many cases the user is limited to taste combinations pre-customized by others, such as the manufacturer of the concentrate or syrup described above or the manufacturer of the beverage dispensing system itself.

Disclosure of Invention

According to various embodiments, fluid mixture dispensing is accomplished by an automated fluid mixture dispensing system. The system produces a mixture of beverages, cleaning products, cosmetic compounds, and/or various other fluid mixtures. Based on user selections, optionally customized by a user, the system is configured to prepare and dispense a plurality of fluid mixtures based on a set of base solvents and ingredients. The system can rely on a predetermined chemical composition of the fluid mixture in order to allow the system to prepare the fluid mixture. For example, chemical analysis of a particular wine or perfume produces a list of chemical ingredients or components that make up the particular wine or perfume. The system disclosed herein is capable of preparing a fluid mixture (e.g., nepheline white wine) depending on such predetermined list of chemical ingredients for the fluid mixture specified by the user. Some of the chemical ingredients may be dispensed in a relatively large percentage by volume in the final mixture (e.g., a glass of wine may have approximately 10-15% ethanol), while other ingredients may be dispensed in a volume of less than 0.1 mL.

Thus, the system disclosed herein is configured to form a fluid mixture based on a predetermined amount of the individual chemical ingredients that make up the fluid mixture, rather than forming the fluid mixture from concentrate or syrup alone, allowing for custom and selection levels not available with current beverage systems. In some embodiments, because small amounts (e.g., less than 0.1 mL) of individual chemical ingredients have a large impact on the fluid mixture properties (e.g., taste), the overall storage or footprint of the system is significantly smaller than those dispensing systems that rely on syrups and/or concentrates.

According to various embodiments, a particular one of the systems disclosed herein includes a plurality of ingredient reservoirs containing zero or more combinations of the respective ingredients and each of the following components: optionally and/or selectively pressurizable cartridges (also referred to as ingredient cartridges) to house a plurality of ingredient reservoirs; a solvent reservoir containing a corresponding solvent (e.g., diluent); a solvent inlet, such as a water inlet connected to an external water supply; a mixing channel; a dissolution chamber; a mixing chamber; a dispenser (e.g., a nozzle); a drip tray (e.g., a waste reservoir); a carbonator; a heat exchanger; a pneumatic system; pumps, such as motor-operated or pressure-operated pumps; a microfluidic pump; a fluid mixture holder sensor (to monitor whether a container for a fluid mixture is present); a drip tray sensor (to monitor the presence of the drip tray and/or the amount of fluid in the drip tray); a dispense sensor (to monitor a dispense profile of the fluid mixture); valves, such as electromechanical valves; interconnection hardware, such as pipes and/or tubing; a temperature sensor; a pressure sensor; a flow sensor; a user interface, such as a dashboard; a controller, such as a microprocessor; and any other device, sensor or apparatus used in a fluid dispensing system.

In some embodiments, one or more sources (e.g., ingredient reservoirs and/or solvent reservoirs) are fluidly connected to one or more collection points in a fluid path (flow) from the one or more sources to the dispenser. The collection point includes one or more mixing channels, mixing chambers, dissolution chambers, and dispensers in various embodiments. The number and type of collection points in a particular system depends on the use (e.g., environment) of the system, and/or the type of solvent and type of ingredients required to produce the desired fluid mixture. For example, the beverage dispensing system is configured with different sets of components, including different collection points and/or different collection point arrangements as compared to the cleaning fluid dispensing system.

In some embodiments, the solvent stream from the solvent reservoir is optionally and/or selectively heated and/or cooled by a heat exchanger as it flows to the next collection point. (e.g., solvent flow through a serpentine tube embedded in a heat exchanger). In further embodiments, one heat exchanger is configured to heat and/or cool more than two solvent streams. In various embodiments, any collection point is optionally and/or selectively heated and/or cooled by a heat exchanger. In particular embodiments, one or more temperature sensors are used before and/or after the heat exchanger, such as to measure the temperature of one or more input streams to the heat exchanger or the temperature of an output stream from the heat exchanger. In various embodiments, temperature sensors are used in other parts of the system, such as measuring the temperature of the solvent in the solvent reservoir, the temperature of the solvent from the solvent inlet, or the temperature of a fluid or gas at any point in the system (e.g., a fluid at a dispenser or a gas in a cartridge).

In some embodiments, the controller is programmed to monitor any sensor (e.g., a pressure sensor, a temperature sensor, a fluid mixture holder sensor, a drip tray sensor, or a dispense sensor) in real time and is capable of controlling any controllable component (e.g., a valve, a pump, a microfluidic pump, a pneumatic system, or a heat exchanger). By monitoring the sensors and controlling the controllable components, the controller is programmed to prepare one of a plurality of fluid mixtures according to the respective recipe (also referred to herein as the recipe) using the ingredients and the solvent. The controller is also programmed to produce a series of different types of fluid mixtures, such as a glass of wine, followed by a manhattan cocktail, using the corresponding recipe. The recipe specifies such things as: the amount of one or more ingredients to be used; the amount of one or more solvents to be used; an operational sequence such as a sequence of ingredients and/or solvent dispensing, or a sequence of pump and/or valve actuation; heating and/or cooling instructions for one or more streams and/or collection points; carbonation requirements such as whether the water stream passes through the carbonator or the amount of carbonated water to be added; pre-or post-dispense flush instructions; other techniques for producing fluid mixtures; and any combination of the foregoing. In some embodiments and/or usage scenarios, the controller is programmed to purge (flush) the system, such as by dispensing a quantity of a particular solvent to flow through the system into the drip tray, between generating different types of fluid mixtures. In some embodiments, the system is capable of producing a fluid mixture having a volume of up to one liter. In other embodiments, the system is capable of producing a fluid mixture having a volume of up to three liters. In industrial applications, the system is capable of producing fluid mixtures in volumes of hundreds or thousands of liters.

In various embodiments, the controller may access and/or contain a library of predefined prescriptions. According to various embodiments, the controller generates one or more of the following specific fluid mixtures: responsive to the request, such as through a user interface (e.g., a dashboard); responsive to a command received over a network, such as a command received from a computer or smart phone; automatically generating; according to a programmed schedule; other techniques for controlling the production of a fluid mixture at a desired time and/or location; and any combination of the foregoing. In further embodiments, the prescriptions are customizable, such as by a user on a user interface, or in response to commands received over a network (such as from a computer or smart phone) to modify a particular prescription for a particular need of the user. For example, the user selects a prescription for a manhattan cocktail, but changes the default amount of bittering agent to be used. Another embodiment adjusts The amount of ingredients in a recipe based on changes to The default recipe that are pushed to The device by The controller of The default recipe library via an "Over The Air" update.

In various embodiments having a fluid mixture holder sensor, the controller is programmed to dispense the fluid mixture only when the fluid mixture holder (e.g., a cup or other container under the dispenser) is detected by the fluid mixture holder sensor. For example, the controller will not begin generating the fluid mixture unless the fluid mixture holder sensor detects a container below the dispenser. In another embodiment, the apparatus does not begin the beverage mixing process unless the fluid mixture holder sensor detects a container below the dispenser.

In various embodiments having a drip tray sensor, the controller is programmed to determine whether a drip tray is present and/or the amount of fluid in the drip tray. In further embodiments, the controller is programmed to dispense no fluid mixture if the drip tray is not present and/or the amount of fluid in the drip tray is greater than a threshold.

In various embodiments with dispense sensors, the controller is programmed to determine whether the fluid mixture to be dispensed or being dispensed has a satisfactory dispense profile. For example, the dispense sensor is configured to determine one or more of a flow rate, a viscosity, a carbonation level, a sweetness (e.g., sugar content), or an alcohol content of the fluid mixture.

In some embodiments having a flow sensor, the controller is programmed to determine whether the fluid flow at a point in the system is as expected (e.g., measuring a flow rate) and/or to determine the volume of fluid passing through a point in the system (e.g., measuring an amount of fluid).

In some embodiments having a pressure sensor, the controller is programmed to determine whether the pressure in the container, such as the pressurized cartridge, is at a desired level, and/or monitor the pressure in the container over time.

In various embodiments, the controller is programmed to detect (such as with a sensor) or determine (such as by comparing the accumulated amount of the ingredient to the initial volume) whether the particular ingredient reservoir or the particular solvent reservoir has a corresponding threshold amount less than its remaining content. For example, the controller is programmed to determine that a particular one of the plurality of solvent reservoirs is nearly empty after dispensing the plurality of fluid mixtures.

In some embodiments, the ingredient reservoir contains an ingredient, such as a solid (including a crystal, powder, or other form of solid), liquid, or gas used in the preparation of a fluid mixture. Similarly, the solvent reservoir contains a solvent, such as a liquid or gas, for preparing the fluid mixture. Typically, but not in all embodiments and/or use scenarios, the ingredient reservoir has a smaller volume than the solvent reservoir, and/or the ingredient is used in a lower amount than the solvent in the fluid mixture. Examples of ingredients include flavors, syrups, and chemicals such as citric acid (in solid form or in solution). Examples of the solvent include alcohols (e.g., ethanol or isopropanol), water, ethyl lactate, and propylene glycol. In a specific embodiment, there are at least three ingredient reservoirs. In further embodiments, there are tens or more ingredient reservoirs. Typical systems have more than two solvent reservoirs, but some systems have only one solvent reservoir, while other systems may not have any solvent reservoir. For example, an alcohol-free, low-calorie beverage production system with a carbonator requires only one water reservoir, or alternatively, only one water inlet (no water reservoir). In particular embodiments, at least some of the solvent reservoirs are replaceable and/or refillable (e.g., when the amount of solvent in the solvent reservoir is below a threshold).

According to various embodiments, the amount of a particular ingredient dispensed into the fluid mixture varies from a fraction of a milliliter (e.g., 0.01mL or less) to a few liters (e.g., three liters). (of course, equivalent variations within the amount dispensed are applicable for solid or gaseous ingredients). The amount of the particular solvent used in the fluid mixture similarly varies. For example, a cup of wine has an alcohol content of 10% while a manhattan cocktail has an alcohol content of 34%.

In some embodiments, a plurality of ingredient reservoirs are contained in the cartridge. In further embodiments, there are a plurality of such cartridges, such as ingredient reservoirs having different sets, as a back-up/backup cartridge, and/or in a system having a plurality of dispensers. According to various embodiments, each of the ingredient reservoirs is of one or more types, such as: an air bag; a syringe; a gravity dispensing chamber; a particle dispenser; a pierceable volume (pierceable volume); and any other container for solids (including crystals, powders or other forms of solids), liquids or gases. In various embodiments, all ingredient reservoirs in the cartridge are of the same type. In other embodiments, the cartridge contains more than two types of ingredient reservoirs. According to various embodiments, each of the ingredient reservoirs has one or more dimensions, such as: small size (e.g., one ounce or less, or two ounces or less); in various embodiments, all of the ingredient reservoirs of the cartridge have the same size.

In some embodiments, the system is configured to dispense a predetermined amount of one or more ingredients from an ingredient reservoir in the cartridge into one or more mixing channels. In various embodiments, one or more mixing channels are embedded in and/or are part of the cartridge. In a first example, the ingredients are dispensed by individually controlled microfluidic pumps. In a second example, the cartridge is sealed (or contains a sealed interior chamber) and the ingredients are dispensed at least in part by pressurizing the cartridge (or interior chamber) and controlling the respective valve of each of the ingredient reservoirs to select which ingredient reservoirs are enabled to dispense. The controller is programmed to dispense a given amount of each selected ingredient by controlling and/or by monitoring one or more of the following: pressure (applied to all ingredient reservoirs in the cartridge); a temperature, such as a temperature in a cartridge (or in an internal chamber); the duration and/or extent to which the respective valves of the ingredient reservoirs of the selected ingredients are opened; the viscosity of the selected formulation; the size of the corresponding orifice through which the selected ingredient is dispensed; and other factors that affect the amount of the selected ingredients dispensed.

In some embodiments, the dissolution chamber is used to more fully combine a particular solvent and/or a particular ingredient, such as by using heat (with a heat exchanger) or agitation (e.g., a mechanical agitator).

In some embodiments, a solvent, such as water, flows through the carbonator on a fluid path to a collection point.

According to various embodiments, any particular stream of solvent, ingredients, and/or mixtures thereof is moved (e.g., propelled) by one or more of: pressure, such as air pressure; a pump; a microfluidic pump; gravity; and any other technique for a fluid dispensing system. Further, the particular flow of solvent is optionally and/or selectively controlled at one or more points by fluid control components such as valves (e.g., electromechanical valves such as solenoid or other actuator driven valves, one-way valves, two-way valves, check valves, ball valves, or butterfly valves) and other types of fluid control or fluid diversion mechanisms used in fluid distribution systems.

In a first example system, a plurality of ingredient reservoirs are contained in a pressurizable cartridge. To create a particular fluid mixture, the selected ingredients from the ingredient reservoir are dispensed into the mixing channel using pressure applied to the cartridge. Solvent from the solvent reservoir also flows through the mixing channel, creating an intermediate fluid mixture. The intermediate fluid mixture and one or more other solvents (optionally and/or selectively heated, cooled, and/or carbonated) are mixed in a mixing chamber and dispensed through a dispenser.

The second example system is similar to the first example system, but uses two cascaded mixing chambers, a first mixing chamber receiving the intermediate fluid mixture and some of the one or more solvents, and a second (final) mixing chamber receiving the output of the first mixing chamber and another of the one or more other solvents. This allows mixing of a specific solvent of the one or more other solvents only at the final collection point, for example to reduce pollution and/or minimize loss of carbonation.

In some embodiments, the ingredients in the ingredient store comprise at least one selected from the group consisting of: glycerol (glycerol), fructose, glucose, lactic acid, malic acid, tartaric acid, tripotassium phosphate, sucrose, potassium sulfate, succinic acid, acetic acid, citric acid, tricalcium phosphate, magnesium hydroxide, 3-methylbutan-1-ol, disodium hydrogen phosphate, propanol, starter distillate 9x, ethyl acetate, 2-methylbutan-1-ol, 2-methylpropan-1-ol, 2-phenethyl alcohol, oxacyclopenten-2-one, ferric sulfate heptahydrate, caprylic acid, caproic acid, 3-methylbutyl acetate, capric acid, hex-1-ol, ethyl octanoate, furan-2-yl methanol, ethyl hexanoate, 2-methylpropanoic acid, furan-2-carbaldehyde, ethyl butyrate, 2, 6-dimethoxyphenol, ethyl decanoate, hexyl acetate, 2-phenylethyl acetate, 3-methylsulfonylpropan-1-ol, ethyl propionate, butan-1-ol, 4-hydroxy-3-methoxybenzaldehyde, 5-methylfuran-2-carbaldehyde, isobutyl acetate, 5-pentoxacyclopenten-2-one, 2-methylpropan ethyl 2-oxopropionate, 5-methyl-4-oxoprop-2-one, and 2-methoxyphenol or a phenol-4-methoxyphenol.

It will also be apparent that any one or more of the above variations, embodiments, features, and options may be combined.

Detailed Description

The following provides a detailed description of one or more embodiments of the invention and figures showing selected details of the invention. The invention is described in connection with the embodiments. The embodiments in this disclosure are to be understood as examples, and the invention is obviously not limited to any or all of the embodiments in this disclosure, and the invention encompasses numerous combinations, alternatives, modifications and equivalents. To avoid monotonous recitation, various word labels (such as: first, last, some, various, further, given, other, specific, selected, some, specific, and salient) may be applied to different sets of embodiments; as used in this disclosure, such labeling is obviously not meant to convey quality or any form of preference or prejudice, but merely to facilitate distinguishing between individual groups. The order of some of the operations of the disclosed methods may be altered within the scope of the invention. Wherever multiple embodiments are used to describe variations in a process, system, and/or program instruction features, other embodiments are contemplated that perform static and/or dynamic selection of one of a plurality of corresponding modes of operation, respectively, to one or more of the multiple embodiments, according to predetermined or dynamically determined criteria. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. In various embodiments, different values may be used. These details are provided for the purpose of example and the invention may be practiced according to the claims rather than according to some or all of the details. For the sake of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.

Fluid mixture dispensing systems and methods are described herein. The fluid mixtures described herein may be prepared from a combination of liquids, solids, and gases. According to some embodiments, the fluid mixture dispensing system comprises a combination of one or more of at least some of the following: a solvent reservoir (e.g., a water reservoir and/or an alcohol reservoir); a dissolution chamber; a plurality of ingredient reservoirs; a mixing channel; a mixing chamber; a dispenser (e.g., a nozzle); a heat exchanger; and a controller. In some embodiments, the controller is configured to receive a request for the fluid mixture, and in response to receiving the request for the fluid mixture, the controller is configured to: (1) Flowing a predetermined amount of at least one solvent from at least one solvent reservoir (e.g., a predetermined amount of water from the water reservoir and/or a predetermined amount of alcohol from the alcohol reservoir) and a predetermined amount of at least one ingredient from the plurality of ingredient reservoirs to at least one mixing channel to form an intermediate fluid mixture; (2) Flowing a predetermined amount of at least one solvent (e.g., water from a water reservoir and/or alcohol from an alcohol reservoir) from at least one solvent reservoir to a first mixing chamber; (3) Flowing a predetermined amount of at least one solvent from at least one solvent reservoir (e.g., a predetermined amount of water from a water reservoir and/or a predetermined amount of alcohol from an alcohol reservoir) and a predetermined amount of at least one ingredient from at least one ingredient reservoir to at least one dissolution chamber to form an intermediate fluid mixture; (4) Flowing a predetermined amount of at least one ingredient from at least one ingredient reservoir to a second mixing chamber; and (5) flowing the contents of the first mixing chamber (if it is not the same as the final mixing chamber), the contents of the second mixing chamber (if it is not the same as the final mixing chamber), and the intermediate fluid mixture (if any) to the final mixing chamber. The system is capable of dispensing a fluid mixture (e.g., from a final mixing chamber) via a dispenser. Thus, the system is capable of producing a plurality of different fluid mixtures based on corresponding requests for the fluid mixtures. Upon receiving a request for a fluid mixture, the system is configured to automatically create and dispense the fluid mixture by flowing a desired amount of solvent (e.g., water and/or alcohol) and/or ingredients from their respective reservoirs to a final mixing chamber, and then dispensing the fluid mixture via a dispenser. In some embodiments, the system has only a single mixing chamber, which may be referred to as the "final" mixing chamber. In various embodiments having multiple mixing chambers, there is typically a final (final) mixing chamber before the dispenser in the sequence of fluid flows. In other embodiments, the dispenser is used as the final mixing chamber.

The fluid mixture dispensing system described herein is capable of dispensing all kinds of fluid mixtures. For example, fluid mixtures include, but are not limited to, beverages (e.g., wine, soda, tea, etc.), cosmetics (e.g., perfumes, cosmetics, etc.), cleaning products (e.g., shampoos, conditioners, soaps, etc.), inks, oils, and various other fluid mixtures.

In some embodiments, the system includes a controller. The term "controller" encompasses one or more controllers (e.g., one or more processors, microprocessors, microcontrollers, embedded control processors, and/or CPUs). In particular embodiments of the present invention, the controller may be a control system for the entire device even though the individual control elements are programmed individually and are not part of a common control hierarchy. In various embodiments, the controller is any device or system that includes one or more computer processors configured to receive a user request, process each of the received requests, and generate and transmit one or more output signals according to the results of the request processing. In some embodiments, the controller is provided in whole or in part as all or part of a desktop computing device, laptop computer, tablet computer, mobile electronic device, special-purpose processing device, computing module, processor, server, cloud computing system, distributed computing system, or the like. In some embodiments, the controller is provided in-situ (e.g., in or attached to the fluid mixture dispensing system) relative to the rest of the fluid mixture dispensing system, while in other embodiments, the controller is provided remotely (e.g., externally and not attached to the fluid mixture dispensing system, such as at a remote server location). Fig. 9 illustrates an example of a controller that can be used with and/or in the fluid mixture dispensing systems disclosed herein. As previously mentioned, any system optionally includes more than one controller. For example, in some embodiments, a first controller is programmed to operate a user interface and communicate with other controllers in the system, and a second controller is programmed to operate a fluid control system (e.g., pump, valve, and/or corresponding sensor).

In some embodiments, the controller is configured to receive user requests, process the user requests, and prepare the respective fluid mixtures for dispensing. In some embodiments, the controller is configured to dispense a fluid mixture (e.g., a beverage) according to the techniques described herein (such as with reference to fig. 1).

In some embodiments, the controller is configured to send one or more instructions and/or control signals to various other components of the fluid mixture dispensing system to cause the system to dispense the fluid mixture. In some embodiments, the instructions and/or control signals are sent by the controller in response to a received request for the fluid mixture and in accordance with a recipe for the requested fluid mixture. The systems referred to herein receive requests, perform actions (such as flowing solvent), etc., including at least a portion of components of the systems (such as controllers, valves, and/or pumps) controlling, being programmed to control, monitor, perform, or otherwise enable receiving requests, performing actions, etc. In a first example, a system control/monitor (or configured to control/monitor) operation refers to a system controller that controls/monitors (or is configured to control/monitor) operation. In a second example, the system flowing solvent refers to the system's pump and/or valve (as controlled by the controller) flowing solvent.

FIG. 1 illustrates a flow chart representative of an exemplary method 100 for dispensing a fluid mixture (e.g., beverage) in accordance with various embodiments. In some embodiments, any one or more variations of method 100 (and/or method 1600 as shown in fig. 13) are optionally and/or selectively combined in whole or in part with any one or more of the systems, methods, devices, components, and/or techniques described elsewhere herein.

Fig. 2A and 2B illustrate examples of fluid mixture dispensing systems 1 according to various embodiments. In some embodiments, the fluid mixture dispensing system can be used for beverage dispensing and/or for a variety of other types of fluid mixture dispensing. According to various embodiments, the fluid mixture dispensing system can be a workstation or consumer electronics device, or a larger device installed in a restaurant or other commercial enterprise.

In some embodiments, the fluid mixture dispensing system 1 includes a housing 2. In further embodiments, the housing is a protective outer housing that houses various internal components of the system. According to various embodiments, the internal components include one or more of at least some of the following: a solvent reservoir (e.g., a water reservoir and/or an alcohol reservoir); a ingredient reservoir; a mixing channel; a mixing chamber; a heat exchanger (e.g., heater/cooler); a dissolution chamber; and various fluid movement mechanisms (e.g., valves, actuators, pumps, etc.). The fluid mixture dispensing system 1 optionally includes a user interface 3, such as a display, keyboard, touch pad, and/or touch screen. The fluid mixing and dispensing system 1 may also be controlled in response to commands received over a network, such as commands received from a computer or smart phone.

At block 102 of fig. 1, in some embodiments, a system (e.g., a controller of the system) receives a request for a fluid mixture (e.g., a beverage). In some embodiments, the request for the fluid mixture is received via a user interface. In some embodiments, the user interface includes a graphical user interface such as a touch screen. In some embodiments, the user interface is configured to display the request and/or any modifications made to the request (e.g., by a user via the user interface). For example, if the user requests soda, the user interface optionally and/or selectively displays options to modify the soda, such as the amount of sugar to be added, carbonation level, total volume, and/or temperature, and the like. In some embodiments, the desired fluid mixture is prepared from a predetermined fluid mixture selected from a library of predetermined fluid mixtures. In various embodiments, a library of predefined fluid mixtures (e.g., names of the predefined fluid mixtures and/or formulas of the predefined fluid mixtures) can be displayed on a user interface for selection by a user. In some embodiments, the library of predefined fluid mixtures is stored remotely from the fluid mixture distribution system and later sent or uploaded to the fluid mixture distribution system. In various embodiments, a library of predetermined fluid mixtures is sent to the controller and stored in a memory of the controller. In some embodiments, the requested fluid mixture includes a modification of the ingredients of the selected predetermined fluid mixture. In various embodiments, the user makes the ingredient modification using a user interface or using a command sent over a network (such as a command sent from a computer or smart phone).

In some embodiments, the user's selection of the predetermined fluid mixture and any subsequent modification are made on a computer (e.g., smart phone, tablet computer, etc.) that is different from the controller of the fluid mixture dispensing system, which is capable of sending the request to the fluid mixture dispensing system, such as over a network.

In some embodiments, the library of predetermined fluid mixtures is a library comprising a series of ingredients (e.g., compounds such as ingredients and/or solvents) and a corresponding list of amounts of each ingredient of each predetermined fluid mixture in the library. For each predetermined fluid mixture, the ingredients and the corresponding quantity list for each ingredient may be obtained from a previous chemical analysis of the predetermined fluid mixture. For example, a chardonnay white wine having a particular identifiable flavor or type may be defined by a list of ingredients of a certain amount of chemical ingredients (such as acids, sugar solutions, etc.), which are mixed into a larger mixture of water and alcohol to form the chardonnay white wine. The number of unique combinations of ingredients may be infinite. Thus, any particular fluid mixture (e.g., wine, soda, perfume, etc.) is combined by a defined list of ingredients and corresponding amounts of each ingredient (such as by chemical analysis of the desired fluid mixture). In some embodiments, the systems disclosed herein digitally accept predetermined fluid mixture information (i.e., a recipe for each predetermined fluid mixture) and then translate that information into a control process (e.g., control of mechanical/electromechanical valves and/or pumps) that dispenses a list of ingredients in the corresponding amounts to form the requested fluid mixture. In various embodiments, the recipe for the predetermined fluid mixture includes additional control information, such as the sequence of operations required to prepare the predetermined fluid mixture, a description of one or more fluid paths to be used, temperature requirements, and/or control of other portions of the fluid dispensing system.

At block 104 of fig. 1, in some embodiments, in response to receiving a request for a fluid mixture, the system is optionally and/or selectively configured to control one or more of: (1) Flowing a predetermined amount of at least one solvent from at least one solvent reservoir (e.g., a predetermined amount of water from a water reservoir and/or a predetermined amount of alcohol from an alcohol reservoir) and a predetermined amount of at least one ingredient from a plurality of ingredient reservoirs to at least one mixing channel to form an intermediate fluid mixture; (2) Flowing a predetermined amount of at least one solvent (e.g., water from a water reservoir and/or alcohol from an alcohol mixture) from the at least one solvent reservoir to a mixing chamber; (3) Flowing a predetermined amount of at least one solvent from at least one solvent reservoir (e.g., a predetermined amount of water from a water reservoir and/or a predetermined amount of alcohol from an alcohol reservoir) and a predetermined amount of at least one ingredient from at least one ingredient reservoir to at least one dissolution chamber to form an intermediate fluid mixture; (4) Flowing a predetermined amount of at least one ingredient from at least one ingredient reservoir to the mixing chamber; and (5) flowing the intermediate fluid mixture (if any) into the mixing chamber. Examples of fluid paths used in block 104 are shown in fig. 11 and 12.

Fig. 11 and 12 illustrate exemplary system flowcharts of fluid mixture dispensing systems according to various embodiments. In fig. 11 and 12, each heat exchanger is optionally included in a given system. When included, each of the heat exchangers can be selectively adjustable in temperature up or down (e.g., temperature of a substance flowing through and/or adhering to the heat exchanger). In various embodiments, the set of metering control elements in fig. 11 and 12 includes at least one of a valve, an electrically-powered element (e.g., solenoid), a pump, a pressure sensor, a temperature sensor, a flow sensor, a mechanical component (e.g., a three-way, check valve, etc.), and/or any other control, diversion, or sensor component for use in a fluid distribution system.

In some embodiments, the system includes at least one solvent reservoir containing at least one solvent. In some embodiments, the at least one solvent comprises water, alcohol, ethyl lactate, and/or propylene glycol. The at least one solvent reservoir supplies the at least one solvent to the fluid mixture to be dispensed. For example, solvent reservoir 8a (e.g., containing water) and solvent reservoir 8b (e.g., containing alcohol) are shown in fig. 8, and fig. 11 and 12 show water reservoir 10. In some embodiments, the system includes multiple solvent reservoirs (e.g., one or more water reservoirs, one or more alcohol reservoirs, one or more propylene glycol reservoirs, one or more ethyl lactate reservoirs, and/or combinations of the foregoing, as well as other variations and/or types of solvent reservoirs). In various embodiments, any of the at least one solvent in the at least one solvent reservoir is optionally and/or selectively diluted. For example, the alcohol reservoir contains 95% alcohol instead of 100% alcohol. In some embodiments, the water reservoir or inlet port optionally includes or is fluidly connected to a water filter that is capable of removing impurities from the water prior to flowing the water to other portions of the system (e.g., to the mixing chamber).

In some embodiments, at least one solvent reservoir supplies a solvent (e.g., any one or more of the at least one solvent) to the fluid mixture to be dispensed. For example, the water reservoir can supply water to the fluid mixture to be dispensed. In some embodiments, the solvent reservoir includes a solvent container contained within the fluid mixture dispensing system to supply one or more solvents to the system. The one or more solvents can be used to dissolve or carry the various ingredients to form the desired fluid mixture. In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of at least one solvent from at least one solvent reservoir to at least one mixing channel (e.g., via a system controller that controls a pump and/or valve) to form an intermediate fluid mixture.

In some embodiments, the water reservoir comprises a water container contained within the fluid mixture dispensing system. In other embodiments, the water reservoir is a standard water outlet, such as a faucet or a water pipe, that is connected to the water inlet of the fluid mixture dispensing system to supply water to the system. In some embodiments and/or use scenarios, water is optionally and/or selectively used as a solvent to dissolve various ingredients to form a desired fluid mixture. In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of water from the water reservoir to the at least one mixing channel to form an intermediate fluid mixture. Such an example is shown in fig. 11 and 12, wherein, in some embodiments and/or usage scenarios, a predetermined amount of water flows to the mixing channel 11. A predetermined amount of water is optionally and/or selectively mixed with alcohol from an alcohol reservoir (e.g., in the alcohol cartridge 13) and/or ingredients from a plurality of ingredient reservoirs in the mixing channel 11 to form an intermediate fluid mixture before flowing to the final mixing chamber 7.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of at least one solvent from at least one solvent reservoir to the mixing chamber. In some embodiments, the system optionally and/or selectively flows a predetermined amount of water from the water reservoir to the mixing chamber in response to receiving a request for the fluid mixture. Such an example is shown in fig. 11 and 12, wherein in some embodiments a predetermined amount of water from the water reservoir 10 can flow to the final mixing chamber 7. Thus, the final mixing chamber is optionally and/or selectively fluidly connected to the water reservoir.

In some embodiments, the system includes at least one dissolution chamber (e.g., dissolution chamber 12 as shown in fig. 11) for dissolving a particular solid and/or gaseous ingredient prior to mixing in the mixing chamber (such as with other ingredients and/or solvents). In these embodiments, the controller is configured to selectively and/or selectively dispense (according to a recipe) a predetermined amount of the at least one ingredient into the dissolution chamber to dissolve before the predetermined amount of the at least one ingredient enters the mixing chamber.

In some embodiments, in response to receiving a request for a fluid mixture, the system optionally and/or selectively flows a predetermined amount of at least one solvent from at least one solvent reservoir to the dissolution chamber to form an intermediate fluid mixture. In various embodiments, at least one solvent reservoir is optionally and/or selectively fluidly connected to the dissolution chamber, and the dissolution chamber is optionally and/or selectively fluidly connected to the mixing chamber. In some embodiments, the system optionally and/or selectively flows a predetermined amount of at least one solvent from at least one solvent reservoir to the gas dissolution chamber to dissolve the gas ingredients, and optionally and/or selectively flows an intermediate fluid mixture of dissolved gases to the mixing chamber. In some embodiments, the system optionally and/or selectively flows a predetermined amount of at least one solvent from at least one solvent reservoir to the solids dissolution chamber to dissolve the solid ingredients, and optionally and/or selectively flows an intermediate fluid mixture of dissolved solids to the mixing chamber.

In some embodiments, in response to receiving a request for a fluid mixture, the system optionally and/or selectively flows a predetermined amount of water from the water reservoir to the dissolution chamber to form an intermediate fluid mixture. In various embodiments, the water reservoir is optionally and/or selectively fluidly connected to the dissolution chamber, and the dissolution chamber is optionally and/or selectively fluidly connected to the mixing chamber. Fig. 11 shows the dissolution chamber 12, and fig. 12 shows the solid dissolution chamber 12a and the gas dissolution chamber 12b. In various embodiments, the gas comprises nitrogen and/or carbon dioxide. In some embodiments, the system optionally and/or selectively flows a predetermined amount of water from the water reservoir to the gas dissolution chamber to dissolve the gas ingredients, and optionally and/or selectively flows an intermediate fluid mixture of dissolved gas to the mixing chamber. In some embodiments, the system optionally and/or selectively flows a predetermined amount of water from the water reservoir to the solids dissolution chamber to dissolve the solid ingredients, and optionally and/or selectively flows an intermediate fluid mixture of dissolved solids to the mixing chamber.

In some embodiments, the predetermined amount of at least one solvent depends on the desired fluid mixture. In other words, the predetermined amount(s) of solvent(s) that generally flow to the final mixing chamber, whether directly or in one or more intermediate fluid mixtures, corresponds to the amount(s) of solvent(s) required to dispense the desired fluid mixture (e.g., a fluid mixture selected from a library of predetermined fluid mixtures). In some embodiments, a predetermined amount of at least one solvent flows from the solvent reservoir through the entire system via at least one pump.

In some embodiments, the predetermined amount of water depends on the desired fluid mixture. In other words, the predetermined amount of water flowing generally to the final mixing chamber corresponds to the desired amount of water in the desired fluid mixture (e.g., a fluid mixture selected from a library of predetermined fluid mixtures), whether flowing directly or in one or more intermediate fluid mixtures. For example, if Chardonnay white wine is selected and the predetermined recipe for Chardonnay requires a total of 50mL of water from the water reservoir, the system flows 50mL of water to the final mixing chamber for incorporation into Chardonnay. In some embodiments, a predetermined amount of water flows from the water reservoir through the entire system via at least one pump.

In some embodiments, the system is configured to monitor the amount of at least one solvent in at least one solvent reservoir. For example, in some embodiments, this is accomplished by various sensors and/or by tracking the amount of at least one solvent that has been dispensed. The system optionally and/or selectively informs a user (e.g., via a user interface) that the solvent reservoir should be refilled or replaced when the amount of solvent in the solvent reservoir is below a specified threshold. In some embodiments, the system is configured to monitor the amount of water in the water reservoir.

In some embodiments, the system includes one or more other solvent reservoirs, such as a second solvent reservoir 8b (as shown in fig. 8), or an alcohol reservoir such as in an alcohol cartridge 13 (as shown in fig. 11 and 12), in addition to one or more water reservoirs (such as water reservoir 10 shown in fig. 11 and 12). In some embodiments, the system comprises a plurality of alcohol reservoirs. Any one or more alcohol reservoirs can supply alcohol to the fluid mixture to be dispensed. As described above, the solvent in the solvent reservoir includes one or more of an alcohol (e.g., ethanol), water, ethyl lactate, propylene glycol, and/or various other alcohols and/or other solvents, as well as various combinations thereof. In various embodiments, as shown in fig. 10, the alcohol in the alcohol reservoir is an alcohol mixture. In some embodiments, the alcohol mixture includes an alcohol and water. For example, FIG. 10 shows that the alcohol solvent may be an alcohol mixture of 10-100% alcohol by volume with 0-90% water by volume.

In some embodiments, the alcohol reservoir comprises an alcohol container contained within the fluid mixture dispensing system. In addition to providing alcohol to the fluid mixture, in various embodiments, the alcohol is optionally and/or selectively used to dissolve various other ingredients to form an intermediate fluid mixture that is part of the desired fluid mixture.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of alcohol from the alcohol reservoir to at least one mixing channel to form an intermediate fluid mixture. An example of this is shown in fig. 11 and 12, where in some embodiments a predetermined amount of alcohol is optionally and/or selectively flowed to the mixing channel 11. A predetermined amount of alcohol is optionally and/or selectively mixed with water from the water reservoir and/or ingredients from the plurality of ingredient reservoirs in at least one mixing channel to form an intermediate fluid mixture prior to flowing to the mixing chamber. In some embodiments, the water and alcohol are mixed prior to entering the at least one mixing channel.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of alcohol from the alcohol reservoir to the mixing chamber. An example of this is shown in fig. 11 and 12, wherein in some embodiments a predetermined amount of alcohol from the alcohol reservoir (in the alcohol cartridge 13) optionally and/or selectively flows to the final mixing chamber 7. Thus, the final mixing chamber is optionally and/or selectively fluidly connected to the alcohol reservoir.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of alcohol from the alcohol reservoir to the dissolution chamber to form an intermediate fluid mixture. In various embodiments, the alcohol reservoir is optionally and/or selectively fluidly connected to the dissolution chamber, and the dissolution chamber is optionally and/or selectively fluidly connected to the mixing chamber. Fig. 11 shows the dissolution chamber 12, and fig. 12 shows the solid dissolution chamber 12a and the gas dissolution chamber 12b. The solids dissolution chamber is configured to dissolve at least one solid ingredient (e.g., sugar) from the at least one ingredient reservoir in a solvent (e.g., alcohol and/or water). The gas dissolution chamber is configured to dissolve at least one gas ingredient from the at least one ingredient reservoir in a solvent (e.g., alcohol and/or water). In some embodiments, the system optionally and/or selectively flows a predetermined amount of alcohol from the alcohol reservoir to the gas dissolution chamber to dissolve the gas ingredients, and optionally and/or selectively flows an intermediate fluid mixture of dissolved gas to the mixing chamber. In some embodiments, the system optionally and/or selectively flows a predetermined amount of alcohol from the alcohol reservoir to the solids dissolution chamber to dissolve the solid ingredients, and optionally and/or selectively flows an intermediate fluid mixture of dissolved solids to the mixing chamber.

In some embodiments, the predetermined amount of alcohol depends on the desired fluid mixture. In other words, the predetermined amount of alcohol that generally flows to the final mixing chamber, whether directly to or in one or more intermediate fluid mixtures, corresponds to the desired amount of alcohol in the desired fluid mixture (e.g., a fluid mixture selected from a library of predetermined fluid mixtures). For example, if Chardonnay white wine is selected and the predetermined recipe for Chardonnay has 14% alcohol by volume, the system flows a predetermined amount of ethanol into the final mixing chamber for mixing so that Chardonnay has 14% alcohol by volume of the final dispensed fluid mixture (based on the volume of the other solvents and/or ingredients). In some embodiments, a predetermined amount of alcohol flows from the alcohol reservoir through the entire system via at least one pump. In some embodiments, the system is configured to monitor the amount of alcohol in the alcohol reservoir.

In some embodiments, the system includes an ingredient reservoir 6 (e.g., as shown in fig. 2B, 3, 4B, 7, and 8). The ingredient reservoir includes an "ingredient," also referred to herein as a "ingredient mixture," to emphasize that the ingredient optionally contains one or more ingredients. As shown in fig. 10, in some embodiments, the ingredient mixture includes at least one primary/functional ingredient. The primary/functional ingredient is at least one of a solid, a liquid or a gas. One example of a primary/functional ingredient is a compound. The use of the word "primary" does not require that the primary/functional ingredient be the ingredient of the ingredient mixture that is present in the greatest amount or concentration as compared to the other ingredients of the ingredient mixture. For example, some primary/functional ingredients, such as capsaicin, may be diluted with several times their volume of solvent (such as water) to form an ingredient mixture. In some embodiments, the primary/functional ingredients include: glycerol, fructose, glucose, lactic acid, malic acid, tartaric acid, tripotassium phosphate, sucrose, potassium sulfate, succinic acid, acetic acid, citric acid, tricalcium phosphate, magnesium hydroxide, 3-methylbutan-1-ol, disodium hydrogen phosphate, propanol, starter distillate 9x, ethyl acetate, 2-methylbutan-1-ol, 2-methylpropan-1-ol, 2-phenethyl alcohol, oxacyclopenten-2-one, ferric sulfate heptahydrate, octanoic acid, hexanoic acid, 3-methylbutylacetate, decanoic acid, hex-1-ol, ethyl octanoate, furan-2-ylmethanol, ethyl hexanoate, 2-methylpropanoic acid, furan-2-carbaldehyde, ethyl butyrate, 2, 6-dimethoxyphenol, ethyl decanoate, hexyl acetate, 2-phenylethyl acetate, 3-methylsulfanyl-propan-1-ol, ethyl propionate, butan-1-ol, 4-hydroxy-3-methoxybenzaldehyde, 5-methylfuran-2-carbaldehyde, isobutyl acetate, 5-pentoxapentan-2-one, 2-methylpropan ethyl 5-butyl-4-methyl-oxapentan-2-one, 2-methoxy-phenol, and 4-methoxy phenol. In various embodiments, the primary/functional ingredients include one or more other ingredients, compounds, or chemicals for producing beverages, perfumes, detergents, cleaners, or other fluid mixtures.

In some embodiments, the ingredient mixture includes one or more compounds at the respective concentrations. In some embodiments, the ingredient mixture includes at least one solvent. In various embodiments, the at least one solvent is any solvent or combination of solvents disclosed herein. For example, the ingredient mixture in the ingredient reservoir is a mixture of citric acid (main/functional ingredient) and water at a specific concentration. Another exemplary ingredient mixture is a mixture of potassium sulfate (primary/functional ingredient), water, and ethanol. As described herein, one or more batch mixtures are optionally and/or selectively dispensed into a fluid stream (single solvent, or a mixture of one or more solvents, e.g., water and/or ethanol) and combined together to form an intermediate fluid mixture.

In some embodiments, the ingredient mixture includes at least one of a solvent (e.g., water and/or alcohol) and an additive ingredient. In various embodiments, the additive formulation is at least one of a surfactant, a preservative, and/or an emulsifier/stabilizer. Examples of the surfactant include anionic surfactants (e.g., sodium lauryl sulfate and/or sodium lauryl ether sulfate, etc.) and nonionic surfactants (e.g., cocamide monoethanolamine and/or cocamide diethanolamine, etc.). Examples of preservatives include sodium benzoate and/or citric acid and the like. Examples of emulsifiers/stabilizers include gellan gum and/or guar gum, and the like.

In some embodiments, ingredients are stored in a respective one of a plurality of ingredient reservoirs, such as ingredient reservoir 6 shown in fig. 2B, 3, 4B, 7, and 8. According to various embodiments, each of the ingredient reservoirs is of one or more types, such as: an air bag (for example, reference numeral 6B shown in fig. 5A); a syringe (e.g., reference numeral 6A shown in fig. 5A); a gravity dispensing chamber; a particle dispenser; a pierceable volume; and any other container for solids (including crystals, powders or other forms of solids), liquids or gases. In some embodiments, all ingredient reservoirs are of the same type. In other embodiments, the ingredient reservoirs are of more than two types. In further embodiments, the ingredient cartridge contains more than two types of ingredient reservoirs. In some embodiments, the system includes a plurality of ingredient reservoirs. In other embodiments, the system includes only a single ingredient reservoir. According to various embodiments, the ingredient reservoir has one or more dimensions, such as (measured for liquid volume) one ounce, two ounces, four ounces, eight ounces, 16 ounces, 32 ounces, or any other dimension. In some embodiments, all of the ingredient reservoirs in the ingredient cartridge are the same size; in other embodiments, the ingredient cartridge contains ingredient reservoirs of more than two sizes, such as small (e.g., one or two ounces), medium (e.g., four or eight ounces) and large (e.g., 16 or 32 ounces) sizes. For example, the size of the particular ingredient reservoir may be selected based on the anticipated requirements of the ingredients in the particular ingredient reservoir. In various embodiments, more than two ingredient reservoirs in the same ingredient cartridge contain the same ingredient.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of at least one ingredient from a plurality of ingredient reservoirs to at least one mixing channel to form an intermediate fluid mixture. Such an example is shown in fig. 11, wherein, in some embodiments, a predetermined amount of at least one ingredient selectively flows from one or more ingredient reservoirs 6 to mixing channel 11. The predetermined amount of at least one ingredient is mixed with at least one solvent (e.g. water from a water reservoir and/or alcohol from an alcohol reservoir) in a mixing channel 11 before flowing to the final mixing chamber 7. The at least one solvent is capable of dissolving the at least one ingredient and/or transporting the at least one ingredient to a final mixing chamber.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of at least one ingredient from at least one ingredient reservoir to the mixing chamber. Such an example is shown in fig. 11, wherein in some embodiments a predetermined amount of at least one ingredient from one or more ingredient reservoirs 6 selectively flows to a final mixing chamber 7. As shown, at least one ingredient reservoir is fluidly connected to a mixing chamber (such as a final mixing chamber). The at least one ingredient reservoir configured to flow ingredients directly to the mixing chamber is optionally and/or selectively not one of the ingredient reservoirs fluidly connected to a mixing channel, such as the mixing channel 11 as shown in fig. 11 and 12.

In some embodiments, in response to receiving a request for a fluid mixture, the system flows a predetermined amount of at least one ingredient from at least one ingredient reservoir to the dissolution chamber to form an intermediate fluid mixture. In a further embodiment, at least one ingredient reservoir is fluidly connected to the dissolution chamber and the dissolution chamber is fluidly connected to the mixing chamber. Fig. 11 shows the dissolution chamber 12, and fig. 12 shows the solid dissolution chamber 12a and the gas dissolution chamber 12b. The solid dissolution chamber is configured to dissolve at least one solid ingredient (e.g., solid citric acid) from the at least one ingredient reservoir in a solvent (e.g., alcohol and/or water). The gas dissolution chamber is configured to dispense at least one gas ingredient (e.g., CO ₂ ) Dissolved in a solvent (e.g., water). In some embodiments, at least one ingredient reservoir configured to flow ingredients to the dissolution chamber is optionally and/or selectively not one of the ingredient reservoirs fluidly connected to a mixing channel (such as mixing channel 11 as shown in fig. 11 and 12). After at least one ingredient is dissolved in the solvent in the dissolution chamber, the dissolved intermediate fluid mixture flows to a mixing chamber (such as the final mixing chamber 7 shown in fig. 11 and 12).

In some embodiments, the predetermined amount(s) of the ingredient(s) is dependent on the desired fluid mixture. In other words, the predetermined amount(s) of the ingredient(s) that generally flow to the final mixing chamber, whether directly or in one or more intermediate mixtures, corresponds to the desired amount(s) of the ingredient(s) in the desired fluid mixture (e.g., a fluid mixture selected from a library of predetermined fluid mixtures).

In some embodiments, the system is configured to monitor the amount of ingredients in the ingredient reservoir. For example, in some embodiments, this is accomplished by various sensors and/or by tracking the amount of ingredient that has been dispensed. The system optionally and/or selectively informs a user (e.g., via a user interface) that the ingredient reservoir needs to be refilled or replaced when the amount of ingredient in the ingredient reservoir is below a specified threshold. In some embodiments, this includes replacing a cartridge storing an ingredient reservoir, as explained in more detail below.

In some embodiments, a predetermined amount of the ingredient from the ingredient reservoir is configured to be dispensed into the mixing channel, the mixing chamber, and/or the dissolution chamber via at least one pump (such as a microfluidic pump). In some embodiments, each ingredient reservoir is fluidly connected to a respective microfluidic pump for dispensing the ingredients in the ingredient reservoir to the mixing channel, mixing chamber, and/or dissolution chamber. In some embodiments, a plurality of ingredient reservoirs are fluidly connected to a single microfluidic pump for dispensing ingredients from the ingredient reservoirs.

In some embodiments, at least one ingredient reservoir is enclosed in an ingredient cartridge, such as the ingredient cartridge 5 shown in fig. 7 and 8, or the ingredient cartridge 16 shown in fig. 10, 11 and 12. In some embodiments, the system includes at least one ingredient cartridge. In further embodiments, the system comprises two or more ingredient cartridges, and each of the two or more ingredient cartridges is of any of the following types: a solid batching box; a liquid ingredient box; a gas batching box; or a multi-ingredient cartridge. For example, fig. 12 shows at least one of 0 to N solid ingredient cartridges, 0 to N gas ingredient cartridges, 0 to N multi-ingredient cartridges, and 0 to N liquid ingredient cartridges. In some embodiments, the ingredient cartridge includes a plurality of ingredient reservoirs. In further embodiments, an ingredient cartridge (such as a multi-ingredient cartridge) comprises two or more of the following: an ingredient reservoir for the solid ingredient; an ingredient reservoir for liquid ingredients; a dosing reservoir for a gaseous dosing.

In some embodiments, the at least one ingredient cartridge is configured to dispense a predetermined amount of the at least one ingredient from the at least one ingredient reservoir to the mixing channel, mixing chamber, and/or dissolution chamber. In some embodiments, at least one ingredient cartridge is removably attached to the fluid mixture dispensing system such that the at least one ingredient cartridge is refillable, replaceable, maintainable and/or recyclable. In some embodiments, the fluid mixture dispensing system is capable of operating in the event that an ingredient cartridge is missing (e.g., not installed), the ingredient cartridge is partially empty (e.g., only some of the ingredient reservoirs are empty), and/or the ingredient cartridge is (completely) empty.

In some embodiments, a predetermined amount of at least one ingredient in at least one ingredient reservoir is dispensed into the mixing channel, mixing chamber, and/or dissolution chamber via at least one valve. In some embodiments, each ingredient reservoir has a respective valve and a respective actuator (e.g., an electromechanical valve, such as a solenoid valve, having a valve portion and an actuator portion). In some embodiments, each respective valve is configured to cause and/or control the flow of a respective ingredient from the ingredient reservoir to the mixing channel, mixing chamber, and/or dissolution chamber via a respective orifice of the ingredient reservoir. For example, the respective valves provide respective seals on respective apertures of the ingredient reservoir when closed and enable respective ingredients to flow from the ingredient reservoir when open. In various embodiments, the respective valve includes a membrane (such as membrane 30 shown in fig. 5B, 5C, 5D, and 5E) that forms a respective seal when pressed against the respective orifice and is capable of dispensing the respective ingredient when not pressed against the respective orifice.

In some embodiments, at least one ingredient cartridge is pressurizable and/or includes a respective pressurizing chamber (e.g., a respective interior chamber) inside the at least one ingredient cartridge. The pressurized chamber referred to herein refers to the pressurized chamber of the ingredient cartridge, whether in certain embodiments it is the ingredient cartridge itself or in other embodiments it is an internal chamber of the ingredient cartridge. The pressurized chamber houses a plurality of ingredient reservoirs such that pressure (e.g., gas pressure in the pressurized chamber) is applied to the ingredient reservoirs. For example, fig. 12 shows an air node of a pneumatic system ("air pressure generation and storage") that supplies pressurized air to various types of cartridges. In some embodiments, the system is configured to monitor (such as with a pressure sensor) and/or control the pressure in the pressurized chamber. In various embodiments, the pressurizing chambers are pressurized such that when a respective valve of one of the ingredient reservoirs is opened, the ingredient stored in that ingredient reservoir flows out of the ingredient reservoir (at least partially in response to pressure) toward the mixing channel, the mixing chamber, and/or the dissolving chamber. In a further embodiment, the pressurized chamber is raised above a specified minimum pressure before any of the respective valves of the ingredient reservoir are opened.

In some embodiments, the mixing channel, mixing chamber and/or dissolution chamber are fluidly connected to the valve output of the ingredient reservoir such that opening one of the respective valves causes the respective ingredient to flow to the mixing channel, mixing chamber and/or dissolution chamber. In some embodiments, the controller is configured to control the dispensing of a predetermined amount of flow of the respective ingredient from a particular one of the ingredient reservoirs by opening the respective valve of the particular ingredient reservoir for a period of time based on one or more of a pressure in the pressurized chamber, a physical flow characteristic (e.g., viscosity, which may be temperature dependent) of the respective ingredient in the particular ingredient reservoir, a diameter of an opening of the respective valve of the particular ingredient reservoir, and/or a size of the respective orifice of the particular ingredient reservoir. In various embodiments, the system is calibrated to dispense/flow a predetermined amount of the respective ingredients to the mixing channel, the mixing chamber and/or the dissolution chamber based on the pressure in the pressurized chamber, the physical flow characteristics of the respective ingredients, the diameter of the opening of the respective valve and/or the diameter of the respective orifice. In some embodiments, the duration of opening the valve is correspondingly proportional to the amount/concentration of at least one ingredient in the list of ingredients of the requested fluid mixture (e.g., as obtained from chemical analysis of the ingredients required to produce the requested fluid mixture).

In some embodiments, the respective ingredients stored in the ingredient reservoirs are delivered to the respective valves of the ingredient reservoirs via the respective apertures. In some embodiments, the ingredient reservoirs (via respective valves) can be open to a mixing channel (such as mixing channel 11 shown in fig. 11 and 12). In some embodiments, multiple ingredient reservoirs are fluidly connected to a single mixing channel. In various embodiments, one mixing channel is fluidly connected to one or more other mixing channels. In some embodiments, the first mixing channel is fluidly connected to the first plurality of ingredient reservoirs and the second mixing channel is fluidly connected to the second plurality of ingredient reservoirs. For example, a first mixing channel is fluidly connected to 5 to 20 ingredient reservoirs and a second mixing channel is fluidly connected to 5 to 20 identical or different ingredient reservoirs. In various embodiments, at least one solvent (e.g., water and/or ethanol) flows through the mixing channel and mixes with any ingredients dispensed into the mixing channel. In some embodiments, at least one solvent is dispensed into the mixing channel to remove any remaining ingredients.

In some embodiments, one or more mixing channels are formed in the bottom of a plate (such as plate 40 shown in fig. 3, 4A, and 4B). For example, the one or more mixing channels are formed by welding and/or brazing structures to the surface of the plate, by etching and/or engraving the one or more mixing channels into the surface of the plate, and/or by other techniques that create the one or more mixing channels in or on the surface of the plate. All of the one or more mixing channels are optionally and/or selectively fluidly connected to the one or more solvent reservoirs and the mixing chamber. For example, in some embodiments, the solvent enters the at least one mixing channel, and the at least one ingredient from the at least one ingredient reservoir flows into the at least one mixing channel to form an intermediate fluid mixture with the solvent, which then flows to the mixing chamber.

In some embodiments, the respective valves of the ingredient reservoirs are capable of opening (e.g., unsealing) the respective apertures of the ingredient reservoirs (e.g., apertures 15 as shown in fig. 5C, 5D, and 5E) such that the ingredient reservoirs are capable of dispensing at least some of their contents into a mixing channel (such as mixing channel 11 as shown in fig. 5C, 5D, and 5E). In some embodiments, the ingredient reservoir is connected to the membrane valve via a flat plate orifice that dispenses output from the ingredient reservoir. For example, the dispensing end of the ingredient reservoir is a flat plate with a corresponding orifice in the middle (or near) of the plate. When a membrane (e.g., membrane 30 shown in fig. 5B, 5C, 5D, and 5E) is forced (e.g., pressed) against a respective orifice, no ingredient can flow out of the ingredient reservoir (i.e., pressing the membrane against the respective orifice to close the respective valve). In various embodiments, a compliant material such as a rubber pad (e.g., a fluoroelastomer pad), such as compliant material 60 shown in fig. 5D and 5E, is pushed (e.g., pressed) up against the membrane by the action of an actuator, such as actuator 20 shown in fig. 5D and 5E, such that the membrane closes (e.g., seals) valve face 15a (i.e., seals the respective orifice by closing the respective valve). In a further embodiment, the compliant material is a material having a low setting capability such that it provides a consistent and uniform seal over time. In some embodiments, the purpose of the compliant material is to allow misalignment of the actuator and still provide a good seal for the valve seat/orifice. In other words, the compliant material is such that it is able to close the respective orifice when it is pushed (e.g., pressed) up against the membrane and valve. In various embodiments, the area of the actuator (and/or compliant material at the actuator head) is much larger than the area of the respective aperture, allowing the actuator to still achieve sealing of the respective aperture without centering on the respective aperture. However, even when the ingredient reservoirs are in the closed position (i.e., the respective apertures are sealed against the respective apertures by the actuator), any fluid/solvent (such as water and/or alcohol) and any ingredient dispensed from other ingredient reservoirs can flow through the mixing channel and around the closed ingredient reservoirs. For example, in various embodiments, the actuator and membrane do not obstruct the entire width of the mixing channel when sealing the respective apertures. However, when no force pushes (e.g., presses) the membrane against the respective orifice (e.g., as shown in fig. 5E), the respective ingredients can flow through the respective orifice to the mixing channel.

In some embodiments, as described above, at least one solvent from at least one solvent reservoir is sent to the mixing channel such that any ingredients dispensed from the ingredient reservoir into the mixing channel are mixed with the at least one solvent to form an intermediate fluid mixture.

In various embodiments, the diameter of the respective orifice of a particular one of the ingredient reservoirs is in the range of about 0.01 to 5mm or about 0.05 to 1mm, depending on the physical flow characteristics (e.g., viscosity) of the respective ingredient stored in the particular ingredient reservoir. The diameter of the respective orifice is determined at least in part by the physical flow characteristics of the given ingredient and the flow rate through the respective orifice at the pressure of the pressurized chamber. In some embodiments, the valve and ingredient reservoir assembly is connected to an actuator (e.g., solenoid) such as actuator 20 shown in fig. 5D and 5E, which is connected to a substrate such as substrate 25 shown in fig. 4A, 4B, 5C, and 5D. Each actuator has a respective plunger preloaded against a respective one of the respective valves by a respective spring or other force. In some embodiments, the respective plungers are preloaded against the respective valves with a force of about at least or equal to about 1N by the respective springs. In some embodiments with a solenoid actuator, the respective plunger is biased away from the solenoid coil by the respective spring such that the respective plunger pushes (e.g., presses) the respective valve (e.g., against the membrane) with a controlled preload force such that in a default state of the particular solenoid, when the particular solenoid is not activated, the respective valve is sealed.

In some embodiments, the pressure of the pressurized chambers is regulated by the controller and the respective orifices have diameters and thicknesses of known tolerances to ensure that the flow rates of the respective ingredients are predictable and with a determined accuracy. In the case of a predictable flow rate (of determined accuracy), the valve open duration may be used to control the amount (e.g., volume) of the ingredient dispensed. In some embodiments, calibration is used to ensure that open loop dispensing control (e.g., based on pressurization chamber pressure, valve opening time, etc., and no feedback of actual dispensed amount) yields the desired dispensed amount. Alternatively, in various embodiments, the system has closed loop volume metering control.

In some embodiments, accurate dispensing of a predetermined amount of at least one ingredient from a plurality of ingredient reservoirs utilizes real-time software control of one or more actuators and one or more pressure pumps based on input from one or more sensors located throughout the system. In various embodiments, a controller (e.g., one or more embedded control processors) is configured to: converting the recipe information (e.g., predetermined beverage ingredients and amounts) into scheduled and/or ordered dispensing control actions (e.g., control of valves and/or pumps); monitoring what the contents of a given ingredient, water and/or alcohol reservoir are (e.g., using an RFID tag and/or bar code on each reservoir to identify the type of reservoir and/or its contents); monitoring the remaining ingredients, water and/or alcohol levels; and receives user input.

In some embodiments, the controller manages the individual actuators and is configured to perform precise actuator timing to control flow time and, thus, dispense a desired amount (e.g., volume) of ingredients. In some embodiments and/or usage scenarios, a typical formulation for a predetermined fluid mixture includes one to 300 different ingredients, each of which can be in liquid, solid, or gaseous form. In some embodiments, the list of ingredients for a particular predetermined fluid mixture includes dispensing parameters such as the location of an ingredient reservoir containing the particular ingredient in the list of ingredients and the desired amount (e.g., volume) of the particular ingredient dispensed. The system is configured to control and measure pressure, orifice flow rate, and/or ingredient physical flow characteristics in the pressurized chamber, and is configured to make appropriate calculations to determine the valve timing needed to achieve a desired dispensing amount of a particular ingredient. In various embodiments, the system is configured to calculate the most efficient order of mixing solvents and/or ingredients in order to minimize mixing time.

In some embodiments, the controller is configured to manage the individual actuators and adjust actuator timing to control flow time (e.g., how long the valve is open), and thus dispense a desired amount of the respective ingredient from the ingredient reservoir. In some embodiments, actuator health is monitored by the controller. For example, the temperature of the actuator motor windings can be inferred from the measurement of the actuator current. By monitoring the actuator current, the controller is able to detect valves that are not operating within defined performance limits. In some embodiments, the controller is configured to read a voltage drop across a 0.1 ohm shunt resistor in series with the solenoid coil of the actuator. A normally operating solenoid has a well-characterized, repeatable waveform, characterized by the inductive response of the solenoid coil. Measuring the actuator current provides a solenoid response waveform that is sampled by the a/D converter. The slope of the solenoid response waveform is monitored and indicates valve performance. In some embodiments, the cold baseline actuator current is measured at system start-up. In various embodiments, actuator health monitoring allows the system to recover from sticking valves in a non-stick cycle.

In some embodiments, the controller generates a Pulse Width Modulation (PWM) signal that drives the low side MOSFET transistor to activate the actuator. In various embodiments, PWM control allows the controller to drive the actuator solenoid coil to accelerate first, then reduce the duty cycle to a lower value to hold the solenoid in the open position, thereby saving power and reducing heat. In some embodiments, the power supply for the actuators is tightly regulated so that each actuator draws a reliable and repeatable current (if healthy). For example, some prescriptions require only a few solenoids to actuate, while other prescriptions require more than 50. The difference in power draw between these two examples is large enough that the power supply system design is important. In some embodiments, separate solenoid PWM control and direct solenoid current measurement (with minimal delay) can ensure that actuator timing is controlled within very small tolerances, such as within 1 millisecond. In some embodiments, such as in some embodiments having PWM control of a particular actuator, the controller is programmed to maintain the plunger of the particular actuator in an intermediate position (e.g., halfway open) between the sealed position and the fully open position. In the neutral position, the flow rate through the valve operated by a particular actuator may be controlled to be less than the flow rate in the fully open position of the valve. In various embodiments, using an intermediate position between the sealing position and the fully open position enables finer control of the amount of ingredient to be dispensed, and/or provides a method of controlling the amount of ingredient to be dispensed in addition to (or different from) the valve opening duration.

In some embodiments, the system is configured to regulate a dispensing pressure (e.g., the pressure of the gas in the pressurized chamber) that expels the respective ingredient from the ingredient reservoir when the respective valve is opened. For example, depending on the desired fluid mixture, it may be necessary to open several or more valves, and when the fluid is expelled, the opening of the valves changes the total volume in the ingredient reservoir. In some embodiments, the system includes a pressure sensor, a pressure regulator, an accumulator, and/or a pressure pump controlled/monitored by the controller to regulate the pressure in the pressurized chamber. In further embodiments, the controller is programmed to run a closed loop real-time pressure monitoring routine to regulate the pressure in the pressurized chamber and/or to determine the amount of the respective ingredient being expelled from the ingredient reservoir based on a change in the monitored pressure in the pressurized chamber. In some embodiments, a high sensitivity pressure sensor is employed to monitor (with minimal delay) the pressure within the pressurized chamber, thereby enabling the firmware to compensate for pressure changes during dispensing.

As described above, in some embodiments, the respective ingredients in the ingredient store include solid (e.g., powdered) ingredients, including solid ingredient mixtures (i.e., mixtures of multiple solid ingredients such as glucose and sucrose powders). In various embodiments, the ingredient reservoir containing the solid ingredients is a gravity dispensing chamber. In some embodiments, a precise amount of solid (e.g., powdered) ingredients is mechanically moved to the outlet orifice by a separate actuator and from there to the dissolution chamber. According to various embodiments, a single actuator (e.g., a solenoid or voice coil) is used to dispense the contents of a plurality of solid ingredient reservoirs, and/or a corresponding actuator is used to dispense the contents of each solid ingredient reservoir.

In some embodiments, when the ingredient reservoir comprises a syringe, the plunger of the syringe is exposed to a controlled pressure in the pressurized chamber that provides an adjusting force that pushes the plunger. In further embodiments, even if the plunger is removed, the ingredients in the syringe still receive force to expel the ingredients (e.g., into the mixing channel or mixing chamber) when the corresponding valves for those ingredient reservoirs are opened. In some embodiments, inert gas (e.g., argon) is used to protect the ingredients from oxidation/degradation. In other embodiments, the controller is configured to displace at least one plunger of the syringe (such as with a linear motor) to cause a predetermined amount of the ingredients in the syringe to flow to the mixing chamber. Such a system causes a predetermined amount of the ingredients in the syringe to flow to the mixing chamber (and thus to be dispensed in volume) via the injection distance of the plunger. This is a forward placement method, not a time/pressure orifice method. In some embodiments of the time/pressure orifice method, the controller is configured to interpret readings from the pressure sensors and calculate a dispense volume from each individual ingredient reservoir. A combination of these methods may be used together to create a more accurate control of the dispense volume. For example, in further embodiments, the ingredient reservoirs with syringes are controlled using a forward placement method and other ingredient reservoirs are controlled using a time/pressure orifice method.

In some embodiments, the ingredient reservoir is loaded into or attached to the pressurized chamber at a controlled pressure to provide the expelling force.

In some embodiments, as described above, chemical analysis of the fluid mixture provides a detailed list of ingredients that make up the fluid mixture. In various embodiments, the system comprises at least about 5, at least about 10, at least about 20, at least about 30, at least about 40, or at least about 50 ingredient reservoirs. In some embodiments, the cartridge comprises at least about 5, at least about 10, at least about 20, at least about 30, at least about 40, or at least about 50 ingredient reservoirs. In various embodiments, the system comprises at most about 500, at most about 250, at most about 150, at most about 100, at most about 75, at most about 50, at most about 40, at most about 30, at most about 25, at mostAbout 20, up to about 15, or up to about 10 ingredient reservoirs. In some embodiments, the cartridge comprises at most about 500, at most about 250, at most about 150, at most about 100, at most about 75, at most about 50, at most about 40, at most about 30, at most about 25, at most about 20, at most about 15, or at most about 10 ingredient reservoirs. In various embodiments, any of the ingredients is a liquid, a solid, a gas, and/or combinations thereof. For example, the ingredients include an amount of acid in liquid form, an amount of sugar in powder/granular form, and/or an amount of compressed nitrogen or CO in gaseous form ₂ 。

In some embodiments, because the one or more ingredients required to produce a particular fluid mixture are used in small amounts (e.g., less than 0.1mL, less than 0.01mL, less than 0.001mL, or as little as 50 uL), a high level of repeatability and accuracy is required when dispensing the ingredients to form the particular fluid mixture in combination with one or more solvents. In some embodiments, the predetermined amount of at least one ingredient required to form a particular fluid mixture is at most 3L, at most 2L, at most 1L, at most 500mL, at most 250mL, at most 100mL, at most 50mL, at most 25mL, at most 10mL, at most 5mL, at most 1mL, at most 0.5mL, at most 0.1mL, at most 0.01mL, at most 0.001mL, or at most 50uL. Thus, in further embodiments, the respective valves of the ingredient reservoirs support a wide range of precision over a dispensing amount, varying by up to a hundred times, a thousand times or more.

As shown in fig. 11 and 12, the system includes at least one heat exchanger. The heat exchanger is able to selectively regulate the temperature of the fluid in the chamber, flow lines (e.g., pipes or tubes), mixing channels, etc., either upward (i.e., acting as a heater) or downward (i.e., acting as a cooler). For example, a certain beverage should be served at a specific temperature, or a user may select a desired temperature of the beverage to be dispensed to them. In various embodiments, a predetermined amount of one or more solvents (e.g., a predetermined amount of water from a water reservoir and/or a predetermined amount of alcohol from an alcohol reservoir) is cooled and/or heated by a heat exchanger before flowing to the mixing channel, mixing chamber, and/or dissolution chamber. In some embodiments, the temperature to which the one or more solvents are cooled and/or heated is in accordance with a fluid mixture request received by the system (e.g., a user selects a beverage of 10 ℃, etc.).

In some embodiments, the system comprises: a first temperature sensor configured to measure a temperature of the solvent flowing from the solvent reservoir to the at least one heat exchanger; a second temperature sensor configured to measure a temperature of a second solvent flowing from a second solvent reservoir to the at least one heat exchanger; and a third temperature sensor configured to measure a temperature of the solvent mixture (first solvent and second solvent combination) flowing from the at least one heat exchanger to the mixing channel, the mixing chamber, and/or the dissolution chamber. For example, in various embodiments, a system includes: a first temperature sensor configured to measure a temperature of water flowing from the water reservoir to the at least one heat exchanger; a second temperature sensor configured to measure a temperature of the alcohol flowing from the alcohol reservoir to the at least one heat exchanger; and a third temperature sensor configured to measure a temperature of the water/alcohol mixture flowing from the at least one heat exchanger to the mixing channel. In some embodiments, the system adjusts the temperature of at least one heat exchanger based on the temperature sensor measurements such that the intermediate fluid mixture sent to the final mixing chamber meets the required temperature requirements.

In some embodiments, the system includes multiple heat exchangers, such as those shown in fig. 11 and 12, located at various points throughout the system. In some embodiments, the predetermined amount of solvent from the solvent reservoir is optionally and/or selectively cooled and/or heated by the first heat exchanger before flowing to the mixing channel, and the predetermined amount of second solvent from the second solvent reservoir is optionally and/or selectively cooled and/or heated by the second heat exchanger before flowing to the mixing channel. For example, a predetermined amount of water from the water reservoir is cooled/heated by the first heat exchanger before flowing to the mixing channel, and a predetermined amount of alcohol from the alcohol reservoir is cooled/heated by the second heat exchanger before flowing to the mixing channel.

In some embodiments, the system includes a heat exchanger such that any fluid mixture formed in a mixing chamber (such as a final mixing chamber) is optionally and/or selectively cooled and/or heated by the heat exchanger. This helps ensure that the dispensed fluid mixture meets the temperature requirements received in the fluid mixture request. In some embodiments, the mixing channel includes (or is attached to) a heat exchanger to heat the intermediate fluid mixture formed in the mixing channel. In some embodiments, the dissolution chamber includes (or is attached to) a heat exchanger to assist in dissolving the ingredients in the one or more solvents. In some embodiments, the one or more ingredient reservoirs and/or ingredient cartridges include (or are attached to) a heat exchanger to control the temperature of the one or more ingredient reservoirs and/or ingredient cartridges.

In some embodiments, the system includes at least one heat exchanger such that a predetermined amount of at least one solvent from the at least one solvent reservoir is optionally and/or selectively cooled and/or heated by the at least one heat exchanger prior to flowing to the dissolution chamber to aid in dissolution of the predetermined amount of at least one ingredient. In some embodiments, the dissolution chamber itself is optionally and/or selectively heated and/or cooled by a heat exchanger to assist in dissolving a predetermined amount of at least one ingredient.

In some embodiments, the system includes a dispenser (e.g., a nozzle) fluidly connected to the final mixing chamber. At block 106 of fig. 1, in some embodiments, the system is configured to dispense the fluid mixture (e.g., beverage) via the dispenser after the fluid mixture is formed in the final mixing chamber. In some embodiments, a dispenser is used to make a solid (e.g., an extruded fluid mixture) and add control to make a 3D structure, such as by 3D printing. In some embodiments, the final beverage has a volume of at most 3L, at most 2L, at most 1L, at most 750mL, at most 500mL, at most 250mL, at most 200mL, at most 150mL, at most 100mL, at most 50mL, at most 25mL, at most 10mL, at most 5mL, or at most 1 mL.

In some embodiments, the system includes a fluid mixture holder sensor, and the controller is programmed to dispense the fluid mixture only when the fluid mixture holder sensor detects a fluid mixture holder. In some embodiments, the system includes a fluid mixture holder sensor, and the controller is programmed to begin the mixing process only when the fluid mixture holder sensor detects the fluid mixture holder. Fig. 2A, 2B, 11 and 12 show a fluid mixture holder 4 (e.g., a container of the dispensed mixture, such as a wine glass, cup, glass, etc.). In some embodiments, the system includes a drip tray sensor, and the controller is programmed to determine whether a drip tray is present and/or an amount of fluid in the drip tray. In some embodiments, the system includes a dispense sensor, and the dispense sensor is configured to determine whether a dispense profile of the fluid mixture dispense is satisfactory.

In some embodiments, the systems disclosed herein distribute air at various points throughout the system, such as at the air nodes shown in fig. 12. For example, in some embodiments, air is used to maintain pressure in the pressurized chamber. In various embodiments, air is used as a purge for the flow lines, mixing chambers, dissolution chambers, and/or mixing channels, such that there is no solvent or solvent mixture remaining before starting the next fluid mixture. In some embodiments, air is used to aid in dispensing solvent and/or ingredients from the ingredient reservoir. In various embodiments, air is used to control a pneumatic valve to control flow or to assist in ejecting the cartridge.

Although the method in fig. 1 (or fig. 13) is directed to only a single fluid mixture (e.g., beverage), in some embodiments, the system is capable of receiving a request for a second fluid mixture, and in response to receiving the request for the second fluid mixture, repeating and/or modifying the operation of fig. 1 (or the operation of fig. 13) to dispense the second fluid mixture. The second fluid mixture may be the same as or different from the first fluid mixture. For example, the predetermined amount of the at least one solvent and/or the at least one ingredient of the second fluid mixture is different compared to the first fluid mixture. Thus, the predetermined amount of one or more solvents and one or more ingredients from the plurality of ingredient reservoirs of the second fluid mixture may all be different compared to the first fluid mixture. Further, the second fluid mixture may use one or more solvents and/or one or more ingredients that were not used in the first fluid mixture, and/or the second fluid mixture may not use one or more solvents and/or one or more ingredients that were already used in the first fluid mixture.

In some embodiments, the systems disclosed herein are capable of performing many different combinations of fluid mixtures based on respective requests. Upon receiving a request for a fluid mixture, the system automatically generates and dispenses the requested fluid mixture by flowing the appropriate amount of one or more solvents and/or one or more ingredients from their respective reservoirs to the final mixing chamber, and then dispensing via a dispenser.

The network may implement any suitable communication protocol and may be protected by any suitable security protocol. In some embodiments, the network includes any suitably arranged network link that enables transmission and reception of network signals, such as a wireless network connection, a T1 or T3 line, a cable network, a DSL, or a telephone line.

In various embodiments, for example, application software embodying the functionality of the present disclosure is deployed in different configurations, such as in a client/server arrangement or through a web browser as a web-based application or web service.

FIG. 13 illustrates a flow chart representative of an exemplary method 1600 of preparing and dispensing a fluid mixture. The method 1600 begins with a request to dispense a selected fluid mixture (e.g., beverage) (start 1610). The controller of the system determines a series of operations (e.g., control of pumps, valves, etc.) of the system to prepare and dispense the fluid mixture according to the recipe of the selected fluid mixture. The operation in fig. 13 shows an example of an operational sequence for preparing and dispensing a fluid mixture. The order of the operations shown in fig. 13 is merely an example, and other sequences of operations (e.g., changing the order of the operations shown and/or adding other operations or removing one or more of the operations shown) may be optionally and/or selectively used in various embodiments and/or usage scenarios. Furthermore, the size and/or orientation of the boxes in fig. 13 should not be considered important.

Cartridge action 1620 in fig. 13 indicates a subset of operations associated with an ingredient cartridge. In operation 1622, a first amount of fluid (e.g., solvent from the solvent reservoir, and/or a mixture of two or more solvents from two or more solvent reservoirs) flows (e.g., is pumped) from the fluid inlet through one or more channels of the ingredient cartridge so as to "pre-wet" the one or more channels such that the respective ingredients dispensed from the ingredient reservoir are not dispensed into the "dry" channels. In some embodiments and/or use scenarios, the fluid outlet is open (e.g., without a valve, or with a valve open), and at least some of the first amount of fluid is held in the one or more channels due to an effective back pressure from air in the fluid path supplied by the fluid outlet into the one or more channels. In operation 1624, one or more of the respective ingredients from the ingredient reservoir are dispensed into the one or more channels (mixed with any remaining amount of the first amount of fluid), and possibly flow to the fluid outlet at least partially as part of the intermediate fluid mixture. In operation 1626, a second amount of fluid (e.g., solvent) flows from the fluid inlet to the fluid outlet through the one or more channels of the ingredient cartridge. In operation 1628, a second amount of fluid is mixed with the dispensed ingredients and flows through the fluid outlet as a (more) intermediate fluid mixture. The intermediate fluid mixture flows to the mixing chamber (see operation 1640). In various embodiments, the volume of fluid and/or the force of fluid flow (e.g., pumped) overcomes any back pressure at the fluid outlet. In some embodiments, not shown in fig. 13, as part of and/or after operation 1628, air is forced through the fluid inlet to flush any remaining amounts of fluid and/or dispensed ingredients to the fluid outlet. In some embodiments, the flow of the first amount of fluid ends before the dispensing of the ingredients begins in operation 1624 in operation 1622, and the flow of the second amount of fluid begins after the dispensing of the ingredients ends in operation 1624 in operation 1626. In other embodiments, the flow of the first amount of fluid in operation 1622 and/or the flow of the second amount of fluid in operation 1626 overlaps with the dispensing of the ingredients in operation 1624. In further embodiments, the flow of the first amount of fluid in operation 1622 and the flow of the second amount of fluid in operation 1626 are one continuous fluid flow, and the dispensing of the ingredients occurs during one continuous flow in operation 1624.

In some embodiments, the mixing chamber in operation 1640 is a final mixing chamber, and in other embodiments, the mixing chamber is before the final mixing chamber. In operation 1630, one or more other fluids (e.g., respective solvents from one or more solvent reservoirs) are dispensed directly to the mixing chamber. According to various embodiments, operation 1630 occurs one or more of: prior to box action 1620; during at least some of the box actions 1620; after the box action 1620; and any combination of the foregoing (e.g., one or more other fluids are dispensed in a manner other than a continuous flow). In operation 1640, the intermediate fluid mixture and one or more other fluids are mixed in the mixing chamber and then either flow to the final mixing chamber if present (operation 1680) or directly to the dispenser (operation 1690).

In operation 1670, if there is a separate final mixing chamber (separate from the mixing chamber in operation 1640), at least one other fluid (e.g., corresponding solvent from one or more solvent reservoirs) is dispensed directly to the final mixing chamber, where it is mixed with the fluid flow from the previous mixing chamber (operation 1640) in operation 1680.

In operation 1690, the resulting fluid mixture is dispensed, such as by a dispenser (e.g., a nozzle) (from operation 1640 if there is no final mixing chamber; or from operation 1680 if there is a final mixing chamber).
