CANNABIS PREPARATION MIXER RELATED APPLICATION

[0001] This application claims the benefit of U.S. provisional patent application

62/692,315, filed June 29, 2018, titled "Cannabis Preparation Mixer," the entirety of the

disclosure of which is hereby incorporated herein by this reference.

TECHNICAL FIELD

[0002] Aspects of this disclosure relate generally to a chemical preparation mixer and

more specifically to a chemical preparation mixer that weighs, heats, and mixes a mixture

according to a predetermined recipe to achieve a more reliable and consistent result.

BACKGROUND

[0003] The process of creating a chemical mixture often requires multiple

measurements, devices, and processes. For example, in order to create oil infused with cannabis,

the cannabis must first go through decarboxylation, a process where the cannabis is heated up

and held at a specific temperature for a specific amount of time, thus creating

tetrahydrocannabinol ("THC") from the naturally occurring tetrahydrocannabinolic acid

("THCA"). This is typically a carefully monitored process performed with the use of an oven.

[0004] Once the cannabis has gone through decarboxylation, it is then typically

smoked as is, or it is infused into an oil or fat. For the infusion to take place, the cannabis must

be combined with the oil or fat in specific ratios and then stirred while it is heated for a specific

amount of time.

The conventional process for creating such cannabis-infused oil involves human measurement to

get the right mixtures, and requires careful work. In addition, multiple devices are used, such as a

scale, measuring cups, an oven, and a crockpot. The typical instruments used, such as an oven,

la may not have accurate sensors, and the temperature inside may fluctuate significantly. This may alter the amount of THC that is released, making the cannabis more or less potent, often resulting in inconsistencies in the potency for two batches seemingly created by the same process and ingredient quantities. A user that desires to make cannabis-infused oil therefore must deal with a significant amount of uncertainty with respect to the potency of the end product. In addition, different preferences may require different actions from the user. For example, cannabis contains a variety of chemicals that a user may want to draw out, such as THC, cannabidiol ("CBD"), terpenes, and cannabinol ("CBN"). Different temperatures and cook times will draw out more or less of each of these chemicals. Conventional methods of preparing cannabis require that the user know each different recipe and implement the temperatures and cook times carefully depending upon the particular potency of the cannabis used, and the actual temperature and cook times.

DETAILED DESCRIPTION

[0026] This disclosure, its aspects and implementations, are not limited to the specific

components, examples, or configurations disclosed herein. Many additional components,

examples, and configurations known in the art consistent with the intended operation for a

chemical preparation mixer will become apparent for use with particular implementations from

this disclosure. Accordingly, for example, although particular implementations are disclosed,

such implementations and implementing components may comprise any shape, size, style, type,

model, version, measurement, concentration, materials, quantity, and/or the like as is known in

the art for such systems and implementing components, consistent with the intended operation of

a chemical preparation mixer.

[0027] This disclosure concerns a chemical preparation mixer 10 which has a

processor 12 and may have a weighing system 14, a heating system 16, a mixing system 18,

and/or a user interface 20. FIG. 1 illustrates the interaction of these various systems, which are

communicatively coupled to allow data to be communicated between them. This communication

may be electrical, wireless, or any other form of communication.

[0028] The user interface 20 allows a user to input preferences and settings into the

chemical preparation mixer 10. For example, if the user were preparing oil infused with THC or

CBD, the user would have the opportunity to enter the amount of oil used and the levels of THC

or CBD present in the cannabis, as well as the characteristics of the desired end product, before

beginning the process. The user interface 20 reports this information to the processor 12, which

connects all of the different systems and enables them to work together. For example, in some

embodiments, once the processor 12 receives the input data from the user interface 20, it may

send an instruction to the weighing system 14 to measure the weight of the chemicals being used.

The weighing system 14 may then measure the weight and the processor 12 then receives information back from the weighing system 14 indicating the weight of the chemicals being used. The processor 12 may then use the input data and the weight of the chemicals to determine the speed and duration of mixing and the temperature of the mixture necessary to produce the desired end result according to predetermined patterns stored in association with the processor

12, such as different combinations of mixing speeds, time, and temperatures. Persons of skill in

the art will understand what combinations of mixing speed, time, and temperature will produce

different desired results depending on the. The pattern may also be selected based on the type of

chemical used, the desired end result, and the behavior of the selected chemical when subjected

to mixing and heating as known in the art. The processor 12 may instruct the mixing system 18

to mix for the determined amount of time and at the determined speed. In addition, the processor

12 may instruct the heating system 16 to heat the chemicals to the determined temperature. The

temperature of the mixture may be monitored by a temperature probe 22 which is in

communication with the processor 12. The temperature probe 22 may take real time

measurements and report these to the processor 12. In response to these temperature

measurements, the processor 12 may adjust the heating system 18 to either raise or lower the

temperature.

[0029] FIGS. 2 and 3 illustrate a non-limiting embodiment of a chemical preparation

mixer 10 having a processor 12, a weighing system 14, a heating system 16, a mixing system 18,

a user interface 20, and a main housing 24. The main housing 24 may contain at least a portion

of each of the processor 12, weighing system 14, heating system 16, mixing system 18, and user

interface 20. (See also FIG. 7). Each of the weighing system 14, heating system 16, mixing

system 18, and user interface 20 may be partially exposed to allow each to serve its function. For

example, in some embodiments, the weighing system 14 is exposed so that chemicals may be placed on the exposed portion, allowing the chemicals to be weighed, and the heating system 16 is exposed to provide a surface which can heat the mixture directly.

[0030] FIG. 4 illustrates a weighing system 14 of the chemical preparation mixer 10

having a scale plate 26 and a scale sensor 28. The scale plate 26 may comprise a weighing

surface 30 on which to place the chemicals that are being weighed. In particular non-limiting

embodiments, the weighing surface 30 is substantially horizontal, where substantially horizontal

includes any angle within ten degrees of perfectly horizontal or zero degrees. In some non

limiting embodiments, the scale plate 26 is formed as a bowl, allowing the weighing system 14

to contain and weigh a larger portion of a chemical. (See FIG. 11). The scale sensor 28 may be

any sensor capable of measuring the weight of an object. For example, the scale sensor 28 may

comprise a load cell that functions pneumatically or with strain gauges, for example with four

strain gauges positioned near the corners of the load cell. In particular implementations, the

scale plate 26 sits on top of and is in contact with the scale sensor 28 to allow the scale sensor 28

to measure the weight changes as chemicals are placed on and removed from the weighing

surface 30 on the scale plate 26. The scale sensor 28 may be communicatively coupled to the

processor 12 to report the weight of chemicals placed on the weighing surface 30. This recorded

weight can then be used in determining the temperature, length of time, and mixing speed for

producing the user's desired mixture. In some embodiments, the weighing surface 30 is the top

surface 31 of the chemical preparation mixer 10.

[0031] FIG. 5 illustrates a heating system 16 of the chemical preparation mixer 10.

The heating system 16 may include a heating element 32 and various insulation pads 34. The

heating element 32 may be made of any material and in any shape which is suitable for the

purposes of the heating element 32. For example, the heating element 32 may be made with a conductive material which heats up when electrical current is supplied. The heating element 32 may be a flat plate, as illustrated. Alternatively, the heating element 32 may be a wire, coil, or some other shape. The heating system 16 may also include a heat plate 36 which may help distribute the heat supplied by the heating element 32. The heating element 32 or the heat plate

36 may provide a heating surface 38. In particular non-limiting embodiments, the heating surface

38 is substantially horizontal, where substantially horizontal includes any angle within ten

degrees of perfectly horizontal or zero degrees. In some embodiments, the components of the

heating system 16 are arranged with the heat plate 36 sitting on top of the heating element 32 and

the heating element 32 sitting on top of an insulation pad 34. This allows the heating element 32

to supply the necessary heat to the heat plate 36 without damaging other components of the

chemical preparation mixer 10. In embodiments without a heat plate 36, the heating element may

be exposed through the main housing 24 and may sit on top of an insulation pad 34.

[0032] FIGS. 6A-6B illustrate a mixing system 18 of the chemical preparation mixer

10. The mixing system 18 may include a motor comprising a driver 40 and a stirrer 42. The

stirrer 42 is coupled to the driver 40 and inserted into the mixture. The stirrer 42 may contain a

temperature probe 22 or have the temperature probe 22 attached, allowing the temperature probe

22 to take temperature measurements of the mixture as the stirrer 42 stirs the mixture. The stirrer

42 may be of any configuration known in the art for stirrers, or in particular embodiments may

be uniquely formed as a disk stirrer 42, such as that illustrated in FIGs. 6A and 6B. A disk stirrer

42 shown in FIGs. 6A and 6B comprises a plurality of intermittently spaced positively charged

(+) 41 and negatively charged (-) 43 components that are magnetically responsive to changes in

polarity of the driver 40, which is formed as a coil array 40, such that as the magnetic field

emitted from the coil array 40 alternates around the coil array 40, the disk stirrer 42 above the coil array 40 reacts and spins. Stirring blades 45 on the disk stirrer 42, that extend through the disk stirrer 42, help to agitate a mixture or other fluid surrounding the stirrer above the coil array

40.

[0033] The coupling between the driver 40 and the stirrer 42, whatever form of stirrer

42 is used, may be mechanical, magnetic, or any other appropriate coupling. In particular

embodiments in which the stirrer 42 is magnetically coupled to the driver 40, including the

embodiment in FIG. 6A, the driver 40, when configured as a coil array, may be a magnetic coil

array comprising a series of electrically conductive metal coils arranged in a circle. To operate

this embodiment of the driver 40, the processor 12 provides power to each metal coil for a brief

moment, and then provides power to the adjacent metal coil, moving around the circle. When

power is provided to a metal coil, this generates a magnetic field, creating the magnetic coupling

between the driver 40 and the stirrer 42. As the magnetic field generated by the coils moves

around the circle, the stirrer 42 follows, thus rotating in a circle and stirring the mixture.

[0034] The combination of the stirrer 42 and the driver 40 forms a brushless direct

current (DC) motor. The shape of the stirring blades 45 on the disk stirrer 42, that extend

through the stirrer 42 with apertures on either side of the stirring blades 45, provide enhanced

stirring force from the disk stirrer 42 to the fluid within a container into which the stirrer 42 is

placed. In particular embodiments, the disk stirrer 42 may also include a bevel or raised spin

point at a center of the stirrer 42 on the bottom surface to create a spin axis, much like a toy

spinning top, and minimize the contact between the stirrer 42 and the container into which the

stirrer 42 is placed while the stirrer 42 is rotating. In embodiments where the raised spin point is

used, the stirrer 42, when being driven by a magnetic driver 40, will spin and minimization of

friction with the surroundings other than the fluid is advantageous. The shape of the blades 45, which extend above a center portion of the disk and below an outer ring of the disk, assists in enhancing the stirring capability of the stirrer 42 when configured as a disk.

[0035] In another embodiment illustrated in FIG. 6B, the driver 40 may be coupled to

a magnet holder 44. The magnet holder is coupled to at least one magnet 46. Thus, when the

processor 12 supplies power to the driver 40, the driver 40 rotates the magnet holder 44, moving

the magnet 46 in a circular path. With the stirrer 42 magnetically coupled to the magnet 46, the

stirrer 42 also rotates, stirring the mixture.

[0036] In some embodiments, any of the weighing system 14, heating system 16, and

mixing system 18 may be integrated into one assembly. For example, the heating system 16 and

the mixing system 18 may be designed to be a combined assembly that can be removed as a

single unit. In such an embodiment, the components of each of the heating system 16 and the

mixing system 18 may be mixed, rather than be kept separate.

[0037] The processor 12 connects all of the different systems and enables them to

work together, in addition to calculating and controlling start and end times, motor speeds, and

precise cooking temperatures based on the components of the system discussed previously. For

example, a user may select a pre-programmed recipe and enter the amount of oil used through

the user interface 20. In particular implementations where the chemical is cannabis, this

information is then used by the processor 12 to weigh the cannabis, determine the length of time

and temperature at which to heat the heating element 32 to cause the cannabis to go through

decarboxylation, and thus get the desired composition of each of the chemicals. The processor 12

then coordinates the heating element 32, the driver 40, the temperature probe 22, and the scale

sensor 28 to implement a cook time, mixing speed, and cook temperature to produce the

cannabis-infused oil desired. With the temperature probe 22 giving real-time feedback on the temperature of the mixture, the processor 12 can increase or decrease the flow of heat to the heating element 32 to keep the mixture at a precise temperature. The processor 12 also allows the user to get the desired end result without requiring that the user calculate temperatures or cook times. This may limit the variation in potency that is conventionally introduced through human error and separate, disconnected sensors and processes.

[0038] By way of particular example, a desired end result in a particular instance may

be a cannabis-infused butter of a calculated potency, such as 4 milligrams of THC per milliliter

of butter. In such a case, the starting ingredients are butter and cannabis. First, the user places the

cannabis in a decarboxylation canister 60 (FIGs. 2 and 11-12E) and places the canister on the

heat plate 36. The user then selects the decarboxylation process using the user interface 20. The

processor 12 supplies power to the heating element 32 and leaves it running for the device

defined duration based on the default or user-specified temperature. Once the cannabis has

finished with decarboxylation, it may be set aside. Next, the user adds an amount of butter into a

beaker, such as a 100 milliliter beaker, and then enters this value into the user interface 20. The

processor 12 then asks for the known value of THC for the particular strain of cannabis being

used, which may be 20% in this case, and the user enters this value into the user interface 20.

The cannabis is then slowly added to the scale plate 26. As this occurs, the user interface 20

provides the user with the maximum THC concentration of the final solution in real time based

on the weight of cannabis on the scale. Once the desired potency is reached, the user stops

putting cannabis onto the scale sensor 26. In this case, this would occur with 2 grams of

cannabis, which contains 400 milligrams of THC. The user then adds the measured cannabis into

the beaker containing the butter and the stirrer 42, which is on the heat plate 36. The user then

enters the desired potency of 4 milligrams of THC per milliliter of butter and hits begin. The chemical preparation mixer 10 then calculates the amount of time, temperature, and mixing speed needed to make butter with the desired potency, and implements those calculations through control signals sent to the various attached components to make the desired end product.

Other percentages and chemicals may also be implemented, and those of ordinary skill in the art

will understand how to calculate the time, heat, and mixing speed needed for each type of

chemical and desired percent composition. The potency of the final mixture may be calculated

automatically by the processor 12.

[0039] FIG. 7 illustrates the arrangement of the different systems and components of

a non-limiting embodiment of the chemical preparation mixer 10 which has all of the

components contained within the main housing 24. While this embodiment shows the

components in a specific arrangement, other embodiments may alter this arrangement in a

variety of ways without detracting from the function and purpose of the chemical preparation

mixer 10. Therefore, the embodiment and arrangement shown is provided for illustrative

purposes only and does not imply any limitation on other embodiments of the chemical

preparation mixer 10. In the embodiment shown in FIG. 7, the weighing system 14 is at the top

of the main housing 24, with the weighing surface 30 being the top surface 31 of the chemical

preparation mixer 10. The heating system 16 and the mixing system 18 are located near the

bottom of the main housing 24.

[0040] FIGS. 8 through 10 illustrate various embodiments of the stirrer 42. In the

embodiments shown, there may be a magnet in each of the arms 48 which allows the stirrer 42 to

magnetically couple with the driver 40. When the magnets 46 or the magnetic field produced by

the magnetic driver 40 travel in a circle, the stirrer 42 also rotates because the magnets in the

arms 48 attract the stirrer to the magnets 46 or the magnetic field produced by the magnetic driver 40. FIGS. 8 and 9 illustrate a stirrer 42 which has a central hub 50 and multiple arms 48 which extend radially away from the central hub 50. FIG. 10 illustrates an embodiment similar to

FIGS. 8 and 9, but with a ring 54 that surrounds both the central hub 50 and the arms 48, and that

is integral with the ends 52 of each of the arms 48.

[0041] FIGs. 2 and 11-12E show an example of a decarboxylation canister 60. A

decarboxylation canister 60 may comprise a sleeve 62, a canister 64 nested within the sleeve 62,

a basket 66 positioned within the canister 64, and a pan 68, a filter 70 and a lid 72 covering the

decarboxylation canister 60. FIG. 12A illustrates an exploded view of the decarboxylation

canister 60. FIG. 12B shows a front perspective view of the decarboxylation canister 60. FIG.

12C shows a rear perspective view. FIG. 12D shows a side view and 12E is a cross-sectional

view taken along section lines B-B of FIG. 12D. Use of the decarboxylation canister 60 is

described previously herein.

[0042] It will be understood that implementations are not limited to the specific

components disclosed herein, as virtually any components consistent with the intended operation

of a method and/or system implementation for a chemical preparation mixer may be utilized.

Accordingly, for example, it should be understood that, while the drawings and accompanying

text show and describe particular chemical preparation mixer implementations, any such

implementation may comprise any shape, size, style, type, model, version, class, grade,

measurement, concentration, material, weight, quantity, and/or the like consistent with the

intended operation of a method and/or system implementation for a chemical preparation mixer.

[0043] The concepts disclosed herein are not limited to the specific implementations

shown herein. For example, it is specifically contemplated that the components included in a

particular implementation of a chemical preparation mixer may be formed of any of many different types of materials or combinations that can readily be formed into shaped objects and that are consistent with the intended operation of a chemical preparation mixer. For example, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass), carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal,

Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as

Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination

thereof, and/or other like materials; composites and/or other like materials; metals, such as zinc,

magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel,

spring steel, aluminum, any combination thereof, and/or other like materials; alloys, such as

aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or

other like materials; any other suitable material; and/or any combination of the foregoing.

[0044] Furthermore, embodiments of the chemical preparation mixer may be

manufactured separately and then assembled together, or any or all of the components may be

manufactured simultaneously and integrally joined with one another. Manufacture of these
