The disclosure generally relates to cooling a beverage and more particularly relates to systems and methods for vacuum cooling a beverage.
Current techniques for providing a cold beverage to a consumer may include filling a refrigerated cabinet with a number of beverages. This technique unnecessarily cools a number of beverages that may not be used for an extended period. As a result, a large amount of energy is used to cool and maintain beverages that may not be consumed in the short term. Accordingly, there is a need to provide on-demand cooling of beverages. Furthermore, certain parts of the world may not have access to constant or reliable electrical power. Indeed, many parts of the world have no access to electricity whatsoever. Therefore, there is a need to provide a cold beverage to consumers in certain parts of the world that may not have access to constant or reliable electrical power.
Some or all of the above needs and/or problems may be addressed by certain embodiments of the disclosure. According to an embodiment, a system for cooling at least one beverage is disclosed. The system may include a beverage compartment with the beverage positioned therein, a wetted material disposed about the beverage, at least one sorption cartridge, and a vacuum pump. When in a first configuration, the sorption cartridge may be in fluid communication with the beverage compartment, and the vacuum pump may be in fluid communication with the sorption cartridge to create a vacuum in the sorption cartridge and the beverage compartment, causing water to evaporate from the wetted material and be captured by the sorption cartridge, thereby lowering the temperature of the wetted material and in turn cooling the beverage. In addition, when in a second configuration, the sorption cartridge may be detached from the vacuum pump and the beverage compartment to discharge the captured water therein by way of solar energy.
According to another embodiment, a system for cooling at least one beverage is disclosed. The system may include a beverage compartment with the beverage positioned therein, a wetted material disposed about the beverage, at least one sorption cartridge, a vacuum pump, and a heater assembly. When in a first configuration, the sorption cartridge may be in fluid communication with the beverage compartment, and the vacuum pump may be in fluid communication with the sorption cartridge to create a vacuum in the sorption cartridge and the beverage compartment, causing water to evaporate from the wetted material and be captured by the sorption cartridge, thereby lowering the temperature of the wetted material and in turn cooling the beverage. In addition, when in a second configuration, the sorption cartridge may be in fluid communication with the heater assembly to blow heated air through the sorption cartridge to discharge the captured water therein.
Other features and aspects of the disclosure will be apparent or will become apparent to one with skill in the art upon examination of the following figures and the detailed description. All other features and aspects, as well as other system, method, and assembly embodiments, are intended to be included within the description and are intended to be within the scope of the accompanying claims.
The detailed description is set forth with reference to the accompanying drawings. The use of the same reference numerals may indicate similar or identical items. Various embodiments may utilize elements and/or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. Elements and/or components in the figures are not necessarily drawn to scale. Throughout this disclosure, depending on the context, singular and plural terminology may be used interchangeably.
Systems and methods for vacuum cooling a beverage are disclosed herein. In certain embodiments, the vacuum cooling assemblies disclosed herein may provide on-demand cooling of beverages or other products. That is, beverages or other products may be stored at ambient temperature and cooled as needed. In this manner, the vacuum cooling assemblies disclosed herein may eliminate the need for continuous refrigeration of beverages. In turn, the vacuum cooling assemblies disclosed herein may substantially reduce the amount of energy required to provide consumers with cool beverages. In addition, certain embodiments of the vacuum cooling assemblies may operate wholly or partially off-grid. That is, in some instances, the vacuum assemblies may be capable of operating in areas that do not have electrical power or do not have constant or reliable electrical power. Other technical effects and/or solutions may become apparent throughout the disclosure.
In addition, the system 100 may include a second configuration, as depicted in
Any number of beverages 102 may be cooled by the system 100. That is, a single beverage 102 may be cooled, or a number of beverages 102 may be cooled at the same time. The beverages 102 may comprise bottles, cans, or other types of ready-to-drink (RTD) beverages. Although described as bottles or cans, any object capable of holding and transporting a beverage may be used. That is, the beverages 102 may be disposed in any closed containers or the like. Products other than beverages may also be used herein.
In some instances, the beverage compartment 104 may be a vacuum chamber. The beverage compartment 104 may be any suitable size, shape, or configuration. The beverage compartment 104 may accommodate a single or multiple beverages 102. For example, a crate, which may hold a number of beverages 102, may be disposed within the beverage compartment 104. The beverage compartment 104 may accommodate any product. The beverage compartment 104 may include an access door. The access door may be opened and closed for inserting and removing the beverages 102. A seal may form a hermetic seal about the access door when the access door is closed to ensure that the beverage compartment 104 is capable of forming a vacuum therein.
In certain embodiments, the wetted material 106 may include a cloth, foam, sponge, or the like soaked in water. In some instances, the wetted material 106 may form a sleeve about each of the beverages 102. Any suitable material may be used herein. The wetted material 106 may be dampened, soaked, saturated, etc., with water and then placed about the beverages 102. Each beverage 102 may include a corresponding sleeve of wetted material 106, or a single wetted material 106 may be disposed about a number of beverages 102.
In certain embodiments, the sorption cartridge 108 may include an inlet 120, an outlet 122, a support structure 124, a passage 126 within the support structure 124, a screen 128 or perforated plate disposed around the passage 126, and a sorbent material 130 disposed between the screen 128 and the support structure 124. In some instances, the support structure 124 may comprise an elongated tubular structure that includes one or more internal chambers 132. In one embodiment, the support structure 124 may be aluminum. During the cooling cycle, the aluminum may act as a heatsink. The preferred weight ratio of aluminum/sorbent material is approximately 1:1. The support structure 124 may be any suitable material. The screen 128 may be disposed around the passage 126 within the support structure 124. The screen 128 may contain the sorbent material 130 within the internal chambers 132. That is, the sorbent material 130 may be disposed within the internal chambers 132 formed between the screen 128 and the support structure 124. In some instances, the sorbent material 130 may be zeolite. Any suitable sorbent material 130 may be used. The sorption cartridge 108 may be any size, shape, or configuration.
In addition, the sorption cartridge 108 may include an outer shell 134. In some instances, the outer shell 134 may be substantially transparent. In addition, the outer shell 134 may comprise a vacuum insulated outer shell. The outer shell 134 may be disposed about the support structure 124. In some instances, the outer shell 134 may be removable from the support structure 124. That is, the outer shell 134 may be slid on and off of the support structure 124. In this manner, the outer shell 134 may be generally tubular in shape and include an internal bore that is configured to mate with the support structure 124. In some instances, the outer shell 134 may be omitted in the first configuration and then slid onto the support structure 124 in the second configuration. That is, the outer shell 134 may be used when regenerating the sorption cartridge 108 but not used when cooling the beverage 102. In some instances, the outer shell 134 may include an inner wall 136 and an outer wall 138 with closed ends. In this manner, the outer shell 134 may include an internal chamber 140. In some instances, the internal chamber 140 may be a vacuum chamber. That is, the internal chamber 140 may be under vacuum.
In the first configuration, the inlet 120 may be in fluid communication with the beverage compartment 104 via the conduit 112 (such as a hose or the like), and the outlet 122 may be in fluid communication with the vacuum pump 110 via the conduit 114 (such as a hose or the like). As discussed below, the conduits 112, 114 may be in fluid communication with manifolds 152, 154 for accommodating a number of sorption cartridges 108. When the vacuum pump 110 is activated, the sorption cartridge 108 and the beverage compartment 104 may be placed under vacuum. As a result, water may evaporate from the wetted material 106 and pass through the conduit 112 into the sorption cartridge 108 via the inlet 120. The water vapor may flow along the passage 126, through the screen 128, and be captured by the sorbent material 130. As the water evaporates from the wetted material 106, the temperature of the wetted material 106 may be lowered, which in turn may cool the beverage 102. In some instances, a sun shield 142 may be used in the first configuration to block sunlight from warming the sorption cartridge 108 during the cooling process.
Valves may be incorporated into the system 100 to maintain the appropriate pressure in the beverage compartment 104. For example, the valves may maintain the pressure to prevent freezing of the wetted material 106 around the beverage 102. In some instances, a vacuum valve may be disposed along the conduit 114. In addition, an air pressure valve may be attached to the beverage compartment 104. For example, WO 2015/116903, which is incorporated by reference herein in its entirety, includes a vacuum valve 514 and an air inlet valve 520, which could be included in the system 100 of the present application to control the pressure within the beverage compartment 104. Other valve configurations may be used.
After chilling the beverage 102, the sorbent material 130 may be saturated with water. In order to remove the water from the sorbent material 130, the system 100 may be arranged in the second configuration. In the second configuration, the inlet 120 may be detached from the conduit 112 so that it is no longer in communication with the beverage compartment 104. Likewise, the outlet 122 may be detached from the conduit 114 so that it is no longer in communication with the vacuum pump 110. Once detached, the sorption cartridge 108 may be placed in direct sunlight or within a solar reflector panel. Other sources of heat may be used. Sunlight may pass through the outer shell 134 and heat the sorbent material 130 within the support structure 124. In some instances, the sunlight may heat a coating on the inner wall 136, which then heats the support structure 124. The flow of air 118 may pass through the passage 126 from the inlet 120 to the outlet 122. The flow of air 118 may be heated through contact with the hot support structure 124 and sorbent material 130. The sorbent material 130 may expel water vapor as it is heated by the sun. The flow of air 118 may absorb this water vapor and transfer the water vapor to the ambient environment. For example, the flow of air 118 may absorb the water vapor by way of convection inside passage 126. The water vapor may be discharged from the sorption cartridge 108 as the flow of heated air 118 exits the outlet 122. Removal of the water vapor from the sorption cartridge 108 may dry (i.e., regenerate) the sorbent material 130 and enable the sorption cartridge 108 to be reused in the first configuration for cooling the beverage 102. The cycle between the first and second configurations may be repeated over and over to cool the beverage 102 and regenerate the sorption cartridge 108.
In some instances, the sorption cartridge 108 may include an inlet end cap 144 at the inlet 120 and an outlet end cap 146 at the outlet 122. The inlet end cap 144 and the outlet end cap 146 may provide connecting points for connecting the sorption cartridge 108 to the beverage compartment 104 and vacuum pump 110, respectively, via the conduits and/or manifolds. In this manner, the inlet end cap 144 and the outlet end cap 146 may include various valves and/or connection points. In addition, the inlet end cap 144 and the outlet end cap 146 may include a lip 148 that controls the position of the outer shell 134 about the support structure 124. The inlet end cap 144 and the outlet end cap 146 may be any size, shape, or configuration.
In some instances, as depicted in
In the first configuration, the inlet end cap 144 may be attached to the beverage chamber 104 via the conduit 112 or the like, and the outlet end cap 146 may be attached to the vacuum pump 110 via the conduit 114 or the like. The inlet end cap 144, the outlet end cap 146, or both may be removable. Once removed, when in the second configuration, the flow of air 118 may flow through the passage 126 via natural convection or the flow of air 118 may be force through the passage 126 via the blower 150. When the inlet 120 and the outlet 122 are disposed on the same side of the sorption cartridge 108, the inlet end cap 144 and the outlet end cap 146 may be consolidated into a single end cap 156 disposed on one end of the sorption cartridge 108.
In some instances, a number of sorption cartridges 108 may be used. For example, as depicted in
The system 100 also may include a vacuum manifold 154 disposed in fluid communication between the vacuum pump 110 and the sorption cartridges 108. The conduit 114 may connect the vacuum manifold 154 to the vacuum pump 110. In some instances, as depicted in
In use, in order to provide a chilled beverage to a consumer, the beverage 102 may be positioned within the beverage compartment 104, and the wetted material 106 may be disposed about the beverage 102. The vacuum pump 110 may be activated to create a vacuum in the sorption cartridge 108 and the beverage compartment 104, causing water to evaporate from the wetted material 106 and be captured within the sorption cartridge 108, thereby lowering the temperature of the wetted material 106 and in turn cooling the beverage 102. In order to reuse the sorption cartridge 108, it may be dried (i.e., regenerated). To do so, the sorption cartridge 108 may be detached from the vacuum pump 110 and the beverage compartment 104 and placed in direct sunlight or within a solar reflector panel 116 to concentrate the solar energy. Air 118 may flow through the passage 126 via natural convection or air 118 may be force through the passage 126 via the blower 150. The flow of air 118 may absorb and transfer the water vapor within the sorption cartridge 108 to the ambient environment. Removal of the water vapor from the sorption cartridge 108 may regenerate the sorption cartridge 108 and enable the sorption cartridge 108 to be reused in the first configuration for cooling the beverage 102.
In certain embodiments, as depicted in
In addition, as depicted in
The heater assembly 212 also may include a heating element 230 disposed within the conduit 218. The heating element 230 may heat the flow of air 216 from the preheating blower 226 and/or the drying blower 228. In some instances, the heated flow of air 216 may pass through the sorption cartridge 208 to remove the captured water therein.
In certain embodiment, the heater assembly 212 may include a preheating mode 232, a drying mode 234, and a cooling mode 236. The heater assembly 212 may include additional or fewer modes. That is, some of the modes may be omitted. To switch between the various modes, an inlet valve 240 may be disposed about the inlet 220 for opening and closing the inlet 220 of the conduit 218, an outlet valve 238 may be disposed about the outlet 222 for opening and closing the outlet 222 of the conduit 218, and a shutoff valve 242 may be disposed within the conduit 218 for switching the conduit between a closed loop and an open loop. In some instances, the valves may be passive check valves. When in the preheating mode 232, as depicted in
After a predetermined amount of time, the heater assembly 212 may switch from the preheating mode 232 to the drying mode 234. When in the drying mode 234, as depicted in
In some instances, the heater assembly 212 may include a heat exchanger 244 disposed about the inlet 220 and outlet 222. For example, the inlet 220 and the outlet 222 of the conduit 218 may flow through passages inside the heat exchanger 244 that provide interfacial area for heat transfer between the inlet and outlet streams. This arrangement may enable heating of the incoming air at the inlet 220 by cooling heated air 216 as it exits through the outlet 222. In this manner, the heat exchanger 244 may capture otherwise wasted heat exiting the outlet 222.
The hot air 216 from the preheating mode 232 and the drying mode 234 may heat the sorption cartridge 208. In some instances, in order to reuse the sorption cartridge 208 in the first configuration, it may need to be cooled. When in the cooling mode 236, as depicted in
In certain embodiments, the sorption cartridge 208 may include an inlet 248, an outlet 250, a support structure 252, a passage 254 within the support structure 252, a sorbent material 256 disposed within the passage 254, and a screen 258 or perforated plate disposed around the sorbent material 256. The inlet 248 and the outlet 250 may be switched depending on the configuration of the heating assembly 212, the beverage compartment 204, and/or the vacuum pump 210. In some instances, the sorbent material 256 may be zeolite. Any suitable sorbent material 256 may be used. In addition, as discussed below, the support structure 252 may comprise an outer casing and internal fins. The sorption cartridge 208 may be any suitable size, shape, or configuration.
In the first configuration, the inlet 248 of the sorption cartridge 208 may be in fluid communication with the beverage compartment 204 via the conduit 214 (such as a hose or the like), and the outlet 250 of the sorption cartridge 208 may be in fluid communication with the vacuum pump 210 via the conduit 215 (such as a hose or the like). When the vacuum pump 210 is activated, the sorption cartridge 208 and the beverage container 204 may be placed under vacuum. As a result, water may evaporate from the wetted material 206 and pass through the conduit 214 into the sorption cartridge 208 via the inlet 248. The water vapor may flow along the passage 254, through the screen 258, and be captured by the sorbent material 256. As the water evaporates from the wetted material 206, the temperature of the wetted material 206 may be lowered, which in turn may cool the beverage 202.
Valves may be incorporated into the system 200 to maintain the appropriate pressure in the beverage compartment 204. For example, the valves may maintain the pressure to prevent freezing of the wetted material 206 around the beverage 202. In some instances, a vacuum valve may be disposed along the conduit 215. In addition, an air pressure valve may be attached to the beverage compartment 204. For example, WO 2015/116903, which is incorporated by reference herein in its entirety, includes a vacuum valve 514 and an air inlet valve 520, which could be included in the system 200 of the present application to control the pressure within the beverage compartment 204. Other valve configurations may be used.
After chilling the beverage 202, the sorbent material 256 may be saturated with water. In order to remove the water from the sorbent material 256, the system 200 may be arranged in the second configuration. In the second configuration, the inlet 248 may be detached from the conduit 214 so that it is no longer in communication with the beverage container 204. Likewise, the outlet 250 may be detached from the conduit 215 so that it is no longer in communication with the vacuum pump 210. Once detached, the inlet 248 and the outlet 250 of the sorption cartridge 208 may be placed in fluid communication with the conduit 218 of the heater assembly 212. The heater assembly 212 may then remove the water vapor from the sorbent material 256 by providing a heated flow of air 216 via the preheating mode 232, the drying mode 234, or a combination thereof. Next, the sorption cartridge 208 may be cooled via the cooling mode 236.
In some instances, in order to facilitate cooling of the sorption cartridge 208, the support structure 252 may include at least one heat exchanger fin 260 extending therefrom. Any number of heat exchanger fins 260 may be used. In addition, the sorption cartridge 208 may include a number of sorption cartridges 208. The multiple sorption cartridges 208 may be arranged on a carrousel 262 that pivots about an axis 264 between the first configuration and the second configuration. In this manner, while one of the sorption cartridges 208 is being used to cool the beverage 202 in the first configuration, the other sorption cartridge 208 may be regenerated in the second configuration. The sorption cartridges 208 may be rotated over and over between the first and second configurations to continually cool the beverages 202 and be regenerated. In some instances, at least some of the components of the system 200 may be stored in an insulated cabinet 266. Furthermore, a pedal 268 (or handle) may be manipulated by a user to decouple the sorption cartridges so that the carousel 262 may be rotated between the first and second configurations.
In a first configuration, as depicted in
After chilling the beverage, the sorbent material 312 may be saturated with water. The system 300 may include a second configuration for regenerating the sorption cartridge 302. In the second configuration, the sorption cartridge 302 may be detached from the beverage compartment and vacuum pump. In such instances, as depicted in
In the preheating mode, as depicted in
The system 300 also may include a cooling mode. In the cooling mode, the fan 318 may blow ambient (or chilled) air about the sorption cartridge 302 to cool the sorption cartridge 302. For example, during the cooling mode, the fan 318 may blow air 324 along the sorbent material 312 through the cooling passage 322. After the sorption cartridge 302 has been cooled, it may be reused in the first configuration for cooling the beverage. That is, the cooled sorption cartridge 320 may be reattached to the beverage compartment and vacuum pump.
