[0053] As used herein, additives are ingredients that can be added to a beverage to modify and/or enhance its characteristics. The additives can comprise, for example, a
flavoring, flavor enhancer, nutritional supplement, coffee or tea booster, flavor masker, colorant, aromatic, a substance selected for adding body to a beverage base or combinations thereof. The additives can be in fluid or flowable form or any suitable form that can be pumped from the additive containers into the beverage holder.
[0054] The pumps 30 can be operatively connected to the additive containers 20 and so constructed and arranged for dispensing one or more of the additives from the additive containers 20. The pumps 30 can be in fluid communication with the additive containers 20, for example, through flexible tubing 40 that connects each of the individual additive containers 20 to one or more individual pumps 30. In an embodiment, the pumps can be so constructed and arranged in an arc formation above a dispensing area as illustrated in FIGS. 1 and 3A.
[0055] The pumps 30 can also have dispensing outlets 50 for releasing the additive into the beverage cup or holder as illustrated in FIG. 3A. For example, the dispensing outlets 50 can be capillary dispensing tubes for dispensing the additives. Benefits of having the pumps in an arc formation along with using capillary dispensing tubes can include anti- dripping dispensing capabilities and shorter distances from the dispensing unit into a beverage holder for accurate additive dosing (i.e. precise dispensed amounts).
[0056] In an alternative embodiment, one or more of the pumps can comprise a dispensing outlet 50 having a capillary tube insert 52 for providing the dispensing outlet 50 with capillary properties. For example, the tube insert 52 can be positioned inside the dispensing outlet 50 as illustrated in FIG. 3B. The inner diameter of the dispensing outlet 50 can be, for instance, about 0.062 inches and the inner diameter of the tube insert 52 can be about 0.020 inches. There can be about a 0.1 inch length between the tube insert 52 and the exit of the dispensing outlet 50 where the additive remains within the dispensing outlet 50 to reduce or prevent additive dripping. It should be appreciated that the dimensions of the dispensing outlet 50 and the tube insert 52 can be any suitable sizes in accordance with embodiments of the present invention.
[0057] In an embodiment illustrated in FIG. 2, one or more of the additive containers 20 can be releaseably attached to fitments 60. The fitments 60 can be in fluid communication with the tubing 40 that connects to the pumps 30. The fitments 60 can comprise any suitable
shape and material for providing a sealed attachment to the additive containers 20. In an embodiment, the fitments 60 can be attached to a shelf 70 designed for holding the additive containers 20. The shelf 70 can be attached to the support 10 in any suitable manner.
[0058] The additive containers 20 can comprise any material suitable for holding and releasing the additives. For example, one or more of the additive containers 20 can in the form of flexible pouches as illustrated in FIGS. 1-2. One or more of the additive containers can also be releaseably attached to the support for easy replacement when the additive container is empty. The additives containers can also comprise packages other than pouches such as, for example, bag-in-boxes or cartridges 120 as illustrated in FIG. 5 or syringes 220 as illustrated in FIG. 6.
[0059] In an embodiment, the pumps can comprise, for example, diaphragm pumps, peristaltic pumps, syringe pumps, piston pumps, micropumps and/or any other suitable pump. The pumps can also be releaseably attached to the support. For example, as illustrated in FIGS. 1 and 3 A, the additive containers 20 can be connected by tubing 40 to the solenoid diaphragm pumps 30 that can be mounted in an arc fashion on the support 10 below the additive containers 20. Below the dispensing outlets 50 of the pumps 30 is an opening through which one or more additive are discharged. The additives can be discharged directly into the beverage holder before, during or after the beverage has been added.
[0060] In an embodiment illustrated in FIG. 4, the dispensing unit 2 can be so constructed and arranged to be attached to and operatively associated with a beverage dispensing machine 4. For example, the additive dispensing units in embodiments of the present invention can be in a stand alone modular form and adapted for easy addition to and removal from various models of beverage dispensing machines.
[0061] As illustrated in FIG. 4, the modular dispensing unit can further comprise a controller 80 operatively associated with the pumps 30 to vary the amount of one or more additives dispensed from the containers. For example, the controller 80 can be any suitable electronic device capable of operating (e.g. turning on/off, controlling speed) the pumps/pressure mechanisms used to dispense the additives from the containers. The controller can be connected to the pumps by any suitable mechanisms such as, for example,
electrical wires or cables. The controller for the additive dispensing units can be operated manually or automatically, for example, by preprogrammed software.
[0062] It should be appreciated that the controller can be on the additive dispensing unit or on a beverage dispensing machine associated with the additive dispensing unit. If the controller is on the beverage dispensing machine, the pumps can be connected so as to be in operative communication with the controller. For example, the pumps can be connected electronically via a cable to a circuit board that resides inside the body of the beverage dispensing machine. The pumps can be controlled to accurately dispense about 4-6 types of additive shots. It should be appreciated that the pumps can be controlled to allow up any suitable number and volume of different additives into the beverage holder.
[0063] The controller can be also configured for causing the dispensing unit to start dispensing one or more of the additives after and in response to the start of a base liquid dispensed by the beverage dispensing machine. The controller can be configured for causing the pumps to dispense one or more of the additives in pulses of a predetermined duration.
[0064] In another embodiment illustrated in FIG. 6, the present invention provides a modular dispensing unit 202 comprising a support 210, a plurality of syringes 220 having additives attached to the support 210 and a plurality of pressure mechanisms 230 attached to the support 210. For example, in this embodiment, the pressure mechanisms 230 can comprise screw-based stepper motors. The pressure mechanism can comprise other suitable types of stepper motors such as rod-based stepper motors.
[0065] The pressure mechanisms 230 can be operatively coupled to the syringes 220 and so constructed and arranged for dispensing one or more of the additives from the syringes 220 by applying pressure to the syringes 220. As a result, the additives are dispensed from the outlets of the syringes and directed into a beverage holder via dispensing outlets (not shown) attached to the outlets of the syringes 220.
[0066] The syringes 220 can be releaseably attached to the supports 210. In an embodiment, the dispensing unit can further comprise a controller associated with the pressure mechanisms to vary the amount of one or more additives dispensed from the syringes.
[0067] In an alternative embodiment illustrated in FIG. 7, the present invention provides a modular dispensing unit 302 comprising a support 310, a plurality of containers 320 having additives attached to the support 302 and a plurality of pressure mechanisms 330 attached to the support 302. The carousel can allow for easy cleaning and maintenance of the additive containers and pressure mechanisms.
[0068] In this embodiment, the pressure mechanisms 330 can comprise solenoid actuators or any other suitable pressure device. The pressure mechanisms 330 can be operatively coupled to the additive containers 320 and constructed and arranged for dispensing one or more of the additives from the containers 320 by applying pressure to the containers 320. The additive containers 320 can comprise a flexible material that becomes compressed by the pressure mechanisms 330 thereby releasing the additives through outlets on the additive containers 330.
[0069] As illustrated in FIG. 7, the dispensing unit 302 can further comprise a carousel 340 hingedly attached to the support 310. The plurality of containers 320 can be releaseably attached to the carousel 340 and the plurality of pressure mechanisms 330 can be arranged above the additive containers 320. For example, the pressure mechanisms 330 can be operatively coupled to the additive containers 320 and so constructed and arranged for applying pressure to the additive containers 320. As a result, the additives are dispensed from outlets of the additive containers 320 and directed into a beverage holder via dispensing outlets (not shown) attached to the outlets of the additive containers 320.
[0070] In an alternative embodiment illustrated in FIG. 8, the present invention provides a modular dispensing unit 402 comprising a support 410, a plurality of drop and load cartridges 420 having additives attached to the support and a plurality of micropumps 430 attached to the support 410. This embodiment functions in a similar manner as those previously discussed.
[0071] In another embodiment, the present invention provides a method of preparing a beverage using a modular additive dispensing unit. The beverage can comprise a component such as protein-enriched liquid, juice, coffee, tea, cocoa, milk, a cereal or a combination thereof.
[0072] The method can comprise providing a base liquid from a beverage dispensing machine in a beverage holder; dispensing a plurality of additives from an additive dispensing unit into the beverage holder to mix the additives with the base liquid to provide a beverage, wherein the additives are dispensed from a plurality of containers by a plurality of pumps operatively connected to the containers; and controlling the dispensing of additives to vary the concentration of the additives in the base liquid in the beverage holder during the dispensing.
[0073] In this method, the modular additive dispensing unit is operatively associated with the beverage dispensing machine. The modular additive dispensing unit can be operatively associated with the beverage dispensing machine and controlled by the beverage dispensing machine so that the addition of one or more of the additives can be coordinated with the dispensing of the beverage. For example, the controller can cause the additive dispensing unit to dispense one or more additives before, during or after the beverage is dispensed from the beverage machine.
[0074] In an alternative embodiment, the present invention provides another method of preparing a beverage. In this embodiment, the method can comprise mixing a concentrate beverage component with a first liquid to provide a base liquid; dispensing the base liquid from a beverage dispensing machine into a beverage holder; dispensing a plurality of additives from an additive dispensing unit into the beverage holder to mix the additives with the base liquid during the dispensing of the base liquid to provide a beverage, wherein the additives are dispensed from a plurality of containers by a plurality of pumps operatively connected to the containers; and controlling the dispensing of additives to vary the concentration of the additives in the base liquid in the beverage holder during the dispensing.
[0075] The method can further comprise dispensing the base liquid and additives for predetermined time periods automatically in response to operating a dispensing control. For example, the additives can be dispensed in a plurality of pulses of predetermined durations, the base liquid being dispensed at least before and at the beginning of the pulses. The additives can be dispensed from fewer than all of the plurality of containers to make a single beverage.
[0076] In an embodiment, the method can further comprise operating a selection control of the beverage dispensing machine to select one or more of the additive containers from which to dispense the additive.
[0077] The method can further comprise whipping the beverage component and the liquid to produce a foam layer on a liquid layer in the dispensed base liquid. The beverage component can comprise an ingredient such as a coffee, cocoa, or tea base, a sweetener, a whitener or combinations thereof. The whitener can be a non-dairy creamer, a dairy creamer or combinations thereof.
[0078] It should be appreciated that the additive dispensing unit can be designed so as to require little to no cleaning. The additives can be shelf-stable so there is no need to pull the tubing apart for cleaning or rinsing out. The additive dispensing unit can be any suitable length, height and depth for containing the additive containers and pumps or pressure mechanisms.
[0079] All of the components of the additive dispensing units can be at the front of the machine, allowing easy access for a consumer or foodservice operator to add/replace additional additive containers when the unit is empty. In addition, the additive dispensing unit provides easy access for servicing the additive dispensing components should there be any electrical or mechanical issues. The additive dispensing units should not interfere with loading the main beverage packages or servicing the body of the beverage dispensing machine.
[0080] Because the additive dispensing units dispense nutritional or flavor additives directly into the beverage holder or cup, there can be little to no need to clean any components of the additive dispensing units such as the tubing, additive containers or pumps. Additive storage and preparation is contained in packaging containers, which can be disposable. This provides a hygienic beverage machine and saves the machine operator servicing time. Further, because the additive dispensing units dispense nutritional or flavor additives directly into a beverage holder or cup, there is no additive carryover from one serving to the next.
[0081] It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the
present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
