DETAILED DESCRIPTION
(10) Detailed embodiments of the present disclosure are described herein; however, it is to be understood that disclosed embodiments are merely exemplary of the present disclosure, which may be embodied in various alternative forms. Specific process details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in any appropriate implementation.
(11) In description of the
(12) In a modification of the first embodiment, as illustrated in
(13)
(14) Referring to
(15) The dispensing apparatus 100 further includes a dispensing assembly 104. The dispensing assembly 104 is disposed in fluid commination with the beverage source 102. The dispensing assembly 104 may be attached to the beverage source 102 or located separately therefrom, depending on the type and space constrains for the dispensing apparatus 100. In some embodiments, the dispensing assembly 104 may be made of some plastic material like polypropylene, polyethylene terephthalate, or the like.
(16) As depicted in
(17) In some examples, the dispensing apparatus 100 may further include a refrigeration unit 106. The refrigeration unit 106 may be configured to keep the temperature of the liquid inside the beverage source 102 within a predefined temperature limit. Usually, the refrigeration unit 106 may be configured to keep the liquid at a temperature below the ambient temperature. Further, in some examples, the beverage source 102 may be connected with some pressurizing device 108, such as a compressed air cylinder or a compressor. The pressurizing device 108 may be configured to pressurize the liquid, in the beverage source 102, to flow from the beverage source 102 to the dispensing assembly 104. The beverage source 102 may be pressurized to the extent sufficient to force the liquid from the beverage source 102 to the dispensing assembly 104. In one example, the beverage source 102 may be provided with a siphon 110 so that all of the contents of the beverage source 102 may be drained. Further, in one example, the dispensing apparatus 100 may include a diaphragm pump 112 to pump the liquid from the beverage source 102 to the dispensing assembly 104. Diaphragm pumps are conventionally employed in industry for the pumping of beer, soda and other beverages, especially because such pumps are compatible with carbonated as well as non-carbonated liquids. It may be understood that other type of pumps may be employed which are suitable for pumping liquids intended for human consumption.
(18) The dispensing apparatus 100 of the present disclosure further include an infusion chamber 118 arranged in connection with the dispense tube 116. In one example, the infusion chamber 118 may be disposed in line with the dispense tube 116, between the beverage source 102 and the dispensing tap 114. The infusion chamber 118 may be in the form of a cylindrical vessel disposed in fluid communication with the beverage source 102, via the dispense tube 116, to receive the liquid. It may be understood that while the infusion chamber 118 is represented cylindrical in shape, it could be of some other shape, such as a rectangular, hexagonal, or some arbitrary shape. Further, the infusion chamber 118 may be made of any suitable food-grade material. As schematically illustrated in
(19) The infusion chamber 118 may be configured to infuse an infusing ingredient, preferably but not limited to a solid flavoring ingredient with the liquid and thereby desorb flavor components therein. In order to infuse the liquid, the infusion chamber 118 provides an arrangement (not shown) to place ingredients inside thereof and thereby come in contact with the liquid. It may be contemplated by a person skilled in the art that the said arrangement may involve a retractable cover or the like. In one example, the infusion chamber 118 may be removably disposed from the dispense tube 116 to place or replace infusing ingredient therein, and further for cleaning purposes. In some examples, filters 124 may be provided in the infusion chamber 118 at the infusion chamber outlet 122. These filters 124 acts as a holding means for the infusing material when the infusion chamber 118 is drained of the liquid. One of ordinary skill in the art will appreciate that these filters 124 may be made from a variety of materials, such as a metal or plastic perforated screen or mesh or a micron filter and further be produced in a variety of shapes, sizes, and porosity and still achieve the desired filtering and containing effect. It may also be contemplated that a single filter, or multiple filters, could be used in a variety of possible configurations. Further, in some examples, the infusion chamber 118 may be surrounded by a thermoelectric unit (not shown) configured to control a temperature of the liquid during infusion, as required by the infusion process, mostly based on the type and properties of the infusing ingredient and the liquid. Such thermoelectric unit may be contemplated by a person skilled in the art and has not been described in detail for the brevity of the disclosure.
(20) It may be understood that a variety of infusing ingredients may be used in order to infuse the liquid. For example, infusing ingredient can be a plant (such as mint), a flower (such as hops), a fruit (such as an orange, banana, cherry, blueberry, raspberry, or cranberry), a vegetable (such as a pepper or pumpkin), a bean (such as a vanilla or coffee), a nut or legume (such as a pistachio or peanut), a seed (such as cardamom), a wood (such as oak or oak soaked in a distilled spirit), a spice (such as cinnamon or pepper), an herb (such as lavender or rosemary), a root (such as ginger), an extract, a syrup (such as maple syrup), chocolate, candy, or any other type of flavoring item (such as an oil, resin, gel, or powder). Most typically, infusion imparts a new or enhanced flavor to the liquid, although the infusion could be done for other purposes, such as for imparting vitamins, boosters, or remedies for medicinal or health-related reasons to the liquid. These infusing ingredients may come in different forms, such as powders, liquids, solids, pastes, or particulates.
(21) Further, the dispensing apparatus of the present disclosure includes a sensing unit 126 configured to determine a level of carbon-dioxide in the liquid flowing in the dispense tube 116 downstream of the infusion chamber 118. In particular, the sensing unit 126 may be positioned proximal to the infusion chamber outlet 122, specifically outside of the infusion chamber 118. In one example, the sensing unit 126 may be a manometer. In other example, the sensing unit 126 may be a transducer, such as one of an ultrasonic based meter, a capacitance based meter and a resistance based meter or any other type of pressure sensor. The sensing unit 126 may be configured to convert the determined pressure reading to an electronic signal. It may be understood that the pressure of the gaseous components in the liquid is proportional to the level of the carbon-dioxide gas in the liquid, and thus may be substituted for calculation and other purposes.
(22) Further, the dispensing apparatus 100 may include a carbon-dioxide source 128.
(23) In an embodiment, as illustrated in
(24) In an alternate embodiment, as illustrated in
(25) Referring back to
(26) In some examples, the carbonation chamber 132 may include a sparging device 142 coupled to the carbon-dioxide inlet 138 for bubbling the carbon-dioxide gas through the liquid in the carbonation chamber 132. Further, in some examples, the carbonation chamber 132 may have transparent walls, schematically represented by numeral 144, so that the user could watch the bubbles as the carbon-dioxide gas is passed through the liquid. The transparent walls 144 may be made of any clear, food-safe material, such as but not limited to, for example glass, glass derivatives, polycarbonate, acrylic, or PET plastic compound. The walls 144 may further be vacuum jacketed to provide a layer of insulation between the carbonation chamber 132 and the outside. It may be understood that while having clear walls enhance the user's experience, such walls or vacuum jacketed walls are not required for the carbonation chamber 132 to perform the required function. For example, the walls 144 may be made of a non-transparent material, such as stainless steel or aluminum, or a combination of transparent and non-transparent materials, such as stainless steel with glass windows, and still fall within the scope of the present disclosure.
(27) The dispensing apparatus 100 of the present disclosure further includes a control unit 146. It may be understood that the control unit 146 may be a computing device, including typical components like, a memory, a secondary storage device, a processor, an input device, a display device, and an output device. The memory may include random access memory (RAM) or similar types of memory and the secondary storage device may include some non-volatile means of data storage. Further, the processor may execute programs using data stored in the memory, the secondary storage, or received from the Internet or other network, to perform methods and functions described herein. As illustrated in
(28) Further, the control unit 146 may determine the required level of carbon-dioxide for the liquid dispensing out of the dispensing tap 114. In one example, the said required level may be a predefined value set in a memory of the control unit 146. In other example, the control unit 146 may provide means to dynamically input the said required level by the user based on his/her preference. For this purpose, the control unit 146 may provide input means, such as a keyboard, a mobile app, or any other input means. For example, in some embodiments, the control unit 146 may be configured to be connected to a user interface (not shown) positioned anywhere on the apparatus, for example, on the dispensing assembly 104. In such embodiments, the user interface may include an input mechanism such as a dial, that allows a user to set a pressure/carbonation level (the pressure selected may determine the level of carbonation of the beverage). The selected pressure is received by the control unit 146, which then controls the valve 140 to begin the flow of CO2 from the carbon-dioxide source 128 to the carbonation chamber 132. The Control unit 146 continues allowing CO2 pressure to build until a predetermined pressure is reached. Alternatively, the control unit 146 may allow a specific amount of CO2 to flow from the carbon-dioxide source 128 to the carbonation chamber 132 by calculating the difference between the required level and the existing level using algorithmic functions as would be contemplated by a person skilled in the art.
(29) The control unit 146 is further configured to operate the valve 140 to regulate the flow of carbon-dioxide gas out from the carbon-dioxide source 128. The opening and closing of the valve 140 is controlled based on the calculated difference in order to allow a measured quantity of carbon-dioxide gas to mix with the liquid, downstream of the infusion chamber 118, either directly in the dispense tube 116 or the carbonation chamber 132. It may be understood that the valve 140 is regulated indirectly based on the level of carbon-dioxide in the liquid as determined by the sensing unit 126. The flow of the carbon-dioxide gas is controlled so as to bring the level of carbon-dioxide in the liquid, to be dispensed, to the pre-defined level or the desired level inputted by the user. The amount of carbon-dioxide absorbed by the liquid is controlled by the rate with which the carbon-dioxide gas is introduced in the carbonation chamber 132. In one example, the control unit 146 is configured to at least partially restore the level of carbon-dioxide in the liquid to a level prior to the infusion process, that is, to restore any carbon-dioxide lost in the liquid during the infusion process.
(30) In some examples, the dispensing apparatus 100 may further include a feedback loop. In such configuration, the sensing unit 126 is further configured to determine a post-carbonation level of carbon-dioxide in the liquid in or downstream of the carbonation chamber 132, after the carbon-dioxide gas, from the carbon-dioxide source 128, has been passed there through. If the post-carbonation level is found to be less than the predefined/inputted level, the control unit 146 may be configured to further adjust the opening of the valve 140, based on the determined post-carbonation level of the carbon-dioxide in the liquid, so as to achieve the predefined level in the liquid to be dispensed.
(31)
(32) In some examples, the dispensing apparatus 100 is arranged or constituted in a self-contained unit that may be conveniently shipped to and placed in a commercial establishment for preparation and dispensation of specialty gas infused chilled beverages. The self-contained unit provides a user friendly and convenient infused beverage preparation and dispensing apparatus especially suited for coffee bars, cafeterias, restaurants and other commercial establishments where beverages are served. In such configuration, the dispensing apparatus 100 may or may not include the refrigeration unit 106, capable of cooling the system components and beverage therein to a temperature less than ambient or room temperature, and other ancillary components therein. That said, if the cooling capability is not included in the apparatus, some provision to maintain the beverage in a cooled state may be made according to methods known to one of ordinary skill in the art. In other examples, the dispensing apparatus 100 may include a mounting panel housing which attaches to a wall panel and mounts some or all of the apparatus components to the wall panel. The arrangement of the component parts may be vertical or horizontal and may have components on opposite sides of the wall panel. For example, only the dispensing tap 114 may be visible on one side while the other functional components including the beverage source 102, the refrigeration unit 106, the infusion chamber 118, the carbonation chamber 132, pumps and lines are out of view on the opposite side of the wall panel.
(33)
(34) The present disclosure relates to a dispensing apparatus 100 for dispensing of liquids, such as beer, wine, cider, hard liquor (e.g., distilled beverage, spirit, liquor, hard alcohol, etc.), soft drinks (e.g., cola, soda, pop, tonic, seltzer), iced tea, soda water and other types of carbonated beverages. The dispensing apparatus 100 could be used to provide the end user with varieties of infused and flavored beverages with the desired level of carbon-dioxide. The dispensing apparatus 100 of the present disclosure restores the level of carbon-dioxide in the liquid to a level prior to the infusion process. Thus, at the bars and restaurants with high volume of serving drinks, the user does not have to worry about the loss of carbon-dioxide content in the infused drinks. Since the amount of carbon-dioxide absorbed by the liquid is dependent on the rate with which the carbon dioxide is introduced in the carbonation chamber 132, the dispensing apparatus 100 of the present disclosure could also be used to customize the level of carbonation in the liquid to satisfy a consumer's taste. The user thus has the option to create beverages having varying levels of carbonation to satisfy the palate of the consumer.
(35) The present disclosure further provides a method, generally referred by a numeral 900, for dispensing a carbonated beverage liquid, and illustrated in the form of a flowchart in
(36) Referring to
(37) As will be readily apparent to those skilled in the art, the present invention may easily be produced in other specific forms without departing from its essential characteristics. The present embodiments is, therefore, to be considered as merely illustrative and not restrictive, the scope of the invention being indicated by the claims rather than the foregoing description, and all changes which come within therefore intended to be embraced therein. Many variations, modifications, additions, and improvements are possible. More generally, embodiments in accordance with the present disclosure have been described in the context of preferred embodiments. Functionalities may be separated or combined in procedures differently in various embodiments of the disclosure or described with different terminology. These and other variations, modifications, additions, and improvements may fall within the scope of the disclosure as defined in the appended claims.
