  • bottles or canned beverages can be problematic. Such beverage containers occupy substantial space in refrigerators. Transportation of bulky and heavy ready-to-drink beverages contributes significant carbon emissions. Further, bottled or canned beverages, once opened, must be consumed within a relatively short period to avoid spoilage (e.g., the flattening of a carbonated soda). In order to accelerate the filling speed of carbonated beverage bottles or cans on a production line, anti-foaming additives like E436 have to be dosed into the beverages which is eventually consumed. Bottled or canned beverages are also packed in aluminium cans and plastic bottles which result in waste. For example, plastic (such as PET) bottles for carbonated beverages must be virgin PET and not recycled PET as the latter has a weaker structural integrity which would cause greater loss of carbonation during storage. Further, canned and bottled soda typically lacks a fresh mouthfeel.

  • the drink dispensing apparatus 1 is formed from several components.
  • the drink dispensing apparatus comprises a carbonation chamber 100, a CO2 canister chamber 200, a liquid tank 300, a spigot 400, a drip tray 500, and a capsule chamber 600.
  • Other components such as electronic controls, pump, heater can be also be present.

  • the side wall 104, base 106 and top 108 act together to contain the contents of the carbonation chamber 100.
  • the carbonation chamber can be of any shape.
  • the carbonation chamber can be a cylinder or a cuboid.
  • the carbonation chamber 100 comprises at least one CO2 inlet 110 positioned on the base 106 and/or on the side wall 104 proximate to the base and at least one liquid inlet 126 positioned on the base 106 and/or on the side wall 104.
  • the CO2 inlet 110 introduces CO2 into the carbonation chamber 100 and the liquid inlet 126 introduces a liquid into the carbonation chamber 100.
  • the liquid can be water.
  • the at least one CO2 inlet 110 can be one, two, three, four or five CO2 inlets.
  • the CO2 inlet 110 can further comprise an airstone 112 for breaking up the stream of CO2 into small bubbles. When the size of CO2 bubbles is reduced prior to release into the carbonation chamber 100, the CO2 dissolution into water is improved.
  • the at least one liquid inlet 126 can be one, two, three, four or five liquid inlets.
  • a liquid such as water can be eluted from the liquid inlet 126 to fill up the cavity of the carbonation chamber.
  • a mixing means 114 can be positioned on the base 106.
  • the mixing means mixes the contents of the cavity 122.
  • the mixing means can be a magnetic mixing means.
  • the mixing means can be a shaft and rotor mixing means.
  • the mixing means can comprise blades 116.
  • the blades 116 can be used to crush ice to rapidly decrease the temperature of the liquid in the carbonation chamber 100.
  • CO2 is naturally buoyant with respect to the liquid such that without mixing, CO2 bubbles will naturally take a direct route up to the headspace and escape. With mixing, the route taken by CO2 before reaching the headspace can be lengthened via the circular movement caused by the mixing, thereby improving the carbonation efficiency.
  • Movement of the liquid by the mixing means 114 may form a vortex or other configuration such that the liquid moves upwardly along the inner side wall 104 of the carbonation chamber 100 and forms a void around a centre of rotation of the mixing means 114.
  • This arrangement may have two (or more) effects, including increasing the contact surface area between the liquid and the CO2 in the headspace, thereby enhancing dissolution of CO2 in the liquid, and increasing an area and rate of contact between the liquid and the inner surface of side wall 104 of the carbonation chamber 100 (i.e. the surface of the sidewall 104 facing the contents of the chamber 100), thereby enhancing heat transfer and rapidly cooling down the liquid.
  • This can be advantageous if optional heat removing elements along the outer side walls are present.
  • Movement of the liquid may also cause mixing and/or turbulence, which may also enhance gas dissolution and/or heat transfer.
  • the rotating mixing means 114 further breaks up larger CO2 bubbles into smaller ones, thus providing better dissolution of CO2 in water.
  • the CO2 inlets 110 are positioned close to the base 106 of the carbonation chamber 100, which increases the contact time of the CO2 with water and hence improves carbonation efficiency.
  • the pathway of the CO2 bubbles in the water is altered from a straight path up into the headspace of the carbonation chamber to one that is going around the carbonation chamber before finally ending up in the headspace.
  • the mixing means 114 is rotatable by a mixing drive so as to mix a liquid (such as water) in the carbonation chamber 100.
  • the mixing means 114 may be driven by any suitable arrangement, such as a magnetically-coupled motor drive, a drive shaft that extends through a base of the carbonation chamber, or other.
  • the point of rotation of the mixing means 114 can be at a centre or off-centre position of the carbonation chamber 100.
  • the carbonation chamber 100 can further comprise a perforated receptacle within the cavity of the carbonation chamber 100.
  • the perforated receptacle can be positioned above the mixing means 114.
  • the perforated receptacle is configured to hold ice while allowing liquid to flow around the ice for rapidly cooling the liquid.
  • the carbonation chamber may further comprise an ice inlet positioned at the top and/or on the side wall proximate to the top.
  • the ice inlet may allow for automatic addition of ice into the chamber as required. For example, if the temperature within the chamber is sensed to fall below a threshold, ice from a storage compartment may be delivered via the ice inlet into the chamber. Alternatively, ice may be added into the chamber by the user via the access means 102.
  • the drink dispensing device is thus capable of producing continuous back-to-back servings of ice-cold water (4 to 8 °C) within 2 minutes for each serving.
  • An access means 102 can be positioned on the top 108 of the carbonation chamber 100.
  • the access means 102 is made to be easily accessible, light and strong.
  • the access means 102 opens an orifice to allow the user to add ice into a cavity 122 of the carbonation chamber 100, from which the mixing means 114 facilitates the formation of cold carbonated water. This further improves the carbonation efficiency.
  • the access means 102 can be a sliding door as shown in Figure 2A-D.
  • the access means 102 can also be a trap door.
  • the access means 102 can be made of stainless steel of more than 1.5 mm thick.
  • the access means 102 can further be sealable by sealing means 118, for example by using O-rings. This is more clearly shown in Figure 2D.
  • the sealing means can be a plastic ribbed raft configured to capture the initial internal pressure increase so as to float the access means 102 and seal the carbonation chamber 100.
  • the internal pressure presses the access means 102 into abutment with an overhang 124, such that the sealing means 118 seats the access means 102 against the overhang 124.
  • This allows the access means 102 to be sealed to further prevent loss of CO2 pressure in the carbonation chamber 100.
  • the cover seals the orifice (for example by being lifted up due to the built up pressure) to minimise CO2 loss.
  • a pressurised environment also retains CO2 within the liquid.
  • the cover is configured to withstand up to 5- bar of gas pressure, thus the carbonation chamber can contain or hold a pressure of up to 5 bar without mechanically failing.
  • the access means 102 is a sliding door, it is relatively easy for the consumer to use. Additionally, due to the increased pressure from a first burst of CO2 into the carbonation chamber, the sliding door auto-seals.
  • Figure 2B shows the carbonation chamber 100 with the access means 102 closed (closed configuration).
  • Figure 2C shows the carbonation chamber 100 with the access means 102 opened (open configuration).
  • Room temperature water can thus be added from the liquid inlet 126, which can undergo speedy chilling via high speed spinning while in contact with ice cube(s) inserted by the user via the access means 102.
  • the access means 102 may have a handle for handling by the user.
  • the access means can have a locking means 120.
  • the locking means 120 can be a latch, or can be an electromagnet controllable by a switch, or any other suitable locking mechanism.
  • the carbonation chamber 100 can comprise a sensor for detecting the state of the access means 102.
  • the sensor can be configured to determine if the access means 102 is closed or open. When the access means 102 is open, the mixing means can be configured to not operate.
  • a sensor may be incorporated into the access means 102, to prevent power being supplied for carbonation until the access means 102 is in the closed configuration.
  • the carbonation chamber 100 can further comprise thermoelectric cooling (TEC) elements.
  • the TEC elements can comprise fins that extend from the side walls of the carbonation chamber.
  • the TEC elements can comprise a coil which extends concentrically along the side walls of the carbonation chamber.
  • the TEC elements can be positioned internally or externally of the carbonation chamber.
  • the carbonation chamber 100 By using the above carbonation chamber 100, about 2 to about 5 bar pressure of CO2 may be supplied to the carbonation chamber 100. Preferably, about 4 to about 5 bar pressure may be supplied.
  • the carbonation chamber provides about 75% carbonation efficiency.
  • the carbonation efficiency is the total weight of CO2 dissolved into the liquid divided by the total weight of the CO2 used from the CO2 canister. In comparison, the carbonation efficiency in Sodastream's machine was noted to be highly variable due to the machine setup and higher CO2 pressure. This can lead to higher CO2 wastage.
  • This carbonation chamber 100 is advantageous for reducing the volume of the beverage dispensing machine as well as reduce CO2 wastage. Carbonation also occurs on demand, generated just-in-time when a drink is to be dispensed. Carbonation occurs only when a drink is being prepared, rather than being stored and subjected to de-carbonation. It also allows the maximum allowable level of carbonation in the beverage, so as to provide for maximum enjoyment of the fizzy beverage.
  • the carbonation chamber 100 can be integral within drink dispensing apparatus 1. This provides a sleek and compact apparatus, thus making it suitable for home use.
  • the carbonation chamber 100 further comprises at least one liquid outlet 128 for draining carbonated water.
  • the liquid outlet 128 has a larger inner diameter relative to the liquid inlet 126.
  • the inner dimensions (or diameter) of the liquid outlet 128 (and the downstream tubing connecting the liquid outlet 128 to the capsule chamber and the spigot) may be more than about 5 mm. This ensures that laminar flow is maintained within the tubing and the dissolved CO2 is not inadvertently released. It was found that tubing smaller than 5 mm can cause flow issues as CO2 bubbles may accumulate into a huge bubble, thus blocking the gravitational flow of the carbonated water.
  • the liquid outlet 128 has a same diameter relative to the liquid inlet 126.
  • the liquid inlet 126 and the liquid outlet 128 may together be formed as a single port or orifice.
  • liquid flows into and out of the carbonation chamber 100 via the same port.
  • the port may be connected to a Y-connector in combination with at least one one-way valve. This serves to further reduce the footprint of the drink dispensing apparatus as a result of the compactness of the carbonation chamber, and also to minimise blockage and maintenance due to the fewer tubing, connections and parts.
  • the carbonation chamber 100 further comprises a pressure safety release valve.
  • the valve provides a safety mechanism to prevent overpressure of the carbonation chamber 100. For example, when the pressure in the carbonation chamber 100 exceeds about 6 bar, the pressure safety release valve can be activated to release some of the pent up pressure.
  • the carbonation chamber 100 can have a cavity with a volume of at least about 200 mL, about 220 mL, about 240 mL, about 250 mL, about 260 mL, about 270 mL, about 280 mL, about 300 mL, about 320 mL, about 340 mL, about 360 mL, about 380 mL, about 400 mL, about 420 mL, about 440 mL, about 460 mL, about 480 mL, or about 500 mL.

  • the gas communication means 206 is then actuated which depresses or actuates a release valve (for example a release pin) on the CO2 canister 208, thereby fluidly communicating the CO2 canister 208 with the drink dispensing apparatus 1.
  • the canister attachment means 204 can be a screw hole with female thread 210. This is more clearly seen in Figure 3C. In this way, a CO2 canister 208 with conventional release valve can be used. Other complementary mating means with the CO2 canister 208 may also be used.
  • the canister attachment means 204 may be rigidly secured in a downward facing position such that the CO2 canister 208 can be mated to the canister attachment means 204 in an upright position. By screwing the CO2 canister 208 into the screw hole 210, the gas passageway is sealed (against external pressure) but not yet opened.
  • the canister attachment means 208 can further comprise O-rings to improve the seal.
  • the CO2 canister 208 is first securely mated to the canister attachment means 204 and thus eliminates the possibility of the user fumbling fitting the CO2 canister while CO2 is being released.
  • the CO2 canister 208 can then be actuated using the gas communication means 206 such that gas in the canister can be fluidly communicated to the carbonation chamber for carbonation.
  • the gas communication means 206 can be a lever 212 hinged at an upper end 214.
  • the gas communication means 206 is pivotable about the hinge 214. The pivotal movement actuates a pin 216 along a vertical axis which engages the release valve of the CO2 canister 208 and activates it.
  • the gas communication means 206 can comprise a gradient wedge 220 which engages and acts on protrusion 218.
  • Protrusion 218 is movable connected to pin 216 such that the pivotal movement of the gas communication means 206 back to a vertical position causes the pin 216 to engage the release valve of the CO2 canister 208.
  • the gas communication means 206 can further act as a protective cover. For example, if the CO2 canister is not properly attached and pops out from the CO2 adaptor, this movement is restricted to a downward movement and will not injure the user.
  • the gas communication means 206 is pivotable to a position at about 20 0 to about 90 0 relative to the vertical axis (generally, the axis of the pin 216 or the direction along which gas exist the canister), or preferentially to about 45 0 relative to the vertical axis. This is advantageous in reducing the footprint of the drink dispensing apparatus 1.
  • the canister attachment means 204 is pivotable in line with the gas communication means 206.
  • the canister attachment means 204 and the gas communication means 206 can be pivotable about 90 0 relative to the vertical axis.
  • the canister attachment means 204 is exposed outwardly such that the CO2 canister 208 can be mated with the canister attachment means 204. This allows for greater freedom of motion for attaching the CO2 canister 208.
  • the canister attachment means 204 and the gas attachment means 206 are then pivoted (for example downwards) back to a vertical position.
  • the pin 216 in the gas communication means 206 is actuated to engage the release valve of the CO2 canister 208 such that when the canister attachment means 204 and the gas communication means 206 are in the vertical position, the CO2 canister 208 is in fluid communication with the drink dispensing apparatus 1. In this position, the CO2 canister 208 is also preferentially located within the drink dispensing apparatus 1. This allows the CO2 canister attachment process to be a two-step process for safety.
  • the canister attachment means 204 and the gas communication means 206 are pivoted to a position at about 45 0 relative to the vertical axis. This is advantageous in reducing the footprint of the drink dispensing apparatus 1.
  • the canister attachment means 204 and the gas communication means 206 are separately pivotable.
  • attachment of the CO2 canister 208 is a three step process: attach the CO2 canister 208 to the canister attachment means 204 when pivoted outwardly; pivot the CO2 canister 208 and the canister attachment means 204 to a vertical position; and pivot the gas communication means 206 to the vertical position for fluid communication.
  • the CO2 canister can be attached to the canister attachment means in the insert position. Once securely attached, as the canister attachment means is pivoted towards the ready position, the gas communication means can be actuated to bring the CO2 canister and the drink dispensing apparatus in fluid communication. This allows the CO2 canister attachment process to be a two-step process, instead of a three step process.
  • the gas communication means 206 can also be a prong, or a motorised means so as to minimise user interaction and improve safety.
  • the whole process is a silent process and no gas would be leaked from the system at any point and the user would not be experiencing any "gushing" and thereby, no cause for panic.
  • This also allows at least a steady 4 bar pressure of CO2 to be released from the CO2 canister to the carbonation chamber.
  • the drink dispensing apparatus can comprise a load cell.
  • a load cell is a transducer which converts force into a measurable electrical output.
  • the load cell is connected to the carbonation chamber 100.
  • the load cell allows for better control during the drink preparation process and in the management of drink dispensing apparatus.
  • the load cell can constantly read weight values and input them into a software programme for the appliance to enable customization in beverage preparation.
  • a safety mechanism can be initiated (such as safely release gas pressure and dispense the water into drip tray as waste), and indicate to the user to seek technical help.
  • the load cell further ensures that the carbonation chamber 100 is properly drained before the next drink is prepared.
  • the measurements can be further improved.
  • a base plate with a plurality of holes can be sandwiched between the load cell and the carbonation chamber 100. The holes allows for the position of the dampers to be fine-tuned such that the carbonation chamber 100 can be aligned to maintain a vertical position at rest and/or during activation, and as well as to minimize lateral vibrations.
  • Laminar Flow Means for Minimised Losses of Dissolved CO2 in Carbonated Water In many systems, water, after carbonation, is directed to the outlet via a pump and directly downwards into a mug. However, agitation and/or turbulence of the carbonated water as it flows out will drive the dissolved CO2 out from the water. For example, this can be observed when shaking a can of soft drink prior to opening the can or pouring a beer directly into the base of the mug. This causes the loss of dissolved CO2 to be high even before the user consumes the beverage, resulting in a flat mouthfeel.
  • the carbonation chamber 100 can be positioned at a relatively higher position in the drink dispensing apparatus 1, relative to the spigot 400 ( Figure 4A) and the direction of gravitational pull (i.e. downwards in a global reference frame).
  • the spigot 400 can further comprise a laminar flow means 402 to further improve CO2 retention and/or dissolution.
  • the carbonated water can flow gravitationally via the laminar flow means 402 into the vessel 404.
  • the laminar flow means 402 can be contactable with an inner surface of the vessel 404.

  • the laminar flow means 402 can be a funnel having a concave shape.
  • the laminar flow means 402 can be tapered towards the distal end of the spigot.
  • the laminar flow means 402 can further be movable to accommodate varying sizes of vessels.
  • the laminar flow means 402 can be made of a hard and smooth material such as stainless steel or metal.
  • the laminar flow means 402 can alternatively be flexible in order to increase the contact surface with the inner side of the vessel 404.
  • the laminar flow means 402 can be made of a flexible material such as silicon, PET or PVC. The flexibility allows for the contact surface with the vessel to be maximised such that laminar flow can be further improved. In this way, the maximum allowable level of carbonation in the beverage is retained, so as to provide for maximum enjoyment of the fizzy beverage.
  • Figure 4B and 4C shows a path taken (indicated by arrows) by the carbonated water out from the carbonation chamber 100 and into the vessel 404.
  • the tubing 406 creates a flow path which is configured to minimise sharp turns along the channel from carbonation chamber 100, into the capsule chamber 600, to the spigot 400 and to the vessel 404. This further improves the laminar flow of the carbonated liquid.
  • the drip tray 500 can comprise an ultrasonicator 502.
  • the ultrasonicator 502 can produce ultrasonic waves for ultrasonicating the vessel 404, thereby in turn homogenising the dispensed drink in the vessel 404 as well as provide user customization of aesthetics and carbonation levels of their beverage.

  • the duration of activation can be varied by a software designed to give the best mixing and aesthetics (e.g. beer head for beers) during the course of dispensing the beverage into the vessel 404. Activation could also be initiated by the user should the user want to have a higher foam head or more degassing for a less fizzy beverage.
  • the ultrasonication can have a duration of about 5 s to prevent over-foaming and over-flowing. The duration can be capped to about 5 s for safety.
  • the ultrasonication can be activated by a user to prevent accidental continuous activation of the ultrasonicator 502.
  • the drip tray 500 can further comprise a liquid inlet 504 which is fluidly coupled to a liquid tank. It was found that having some liquid on the drip tray 500 improves contact between the drip tray 500 and the beverage vessel. This improves the performance of the ultrasonicator 502.
