[0002] The present disclosure generally relates to fluid management systems. In the food service and food manufacturing industries, a supply of fluid (e.g., carbon dioxide (CO2) gas) is often used to operate different devices and perform different functions. For example, CO2 may be used (i) in a carbonator device to provide a carbonated food product or (ii) to power a pump or other ancillary device. However, the supply of CO2 may be subject to shortages or supply chain delays, impacting availability. Therefore, a need exists for fluid management systems capable of operating more efficiently and circumventing limited CO2 supply.SUMMARY

The method further includes directing a flow of pressurized air from the low-pressure manifold to the at least one low- pressure outlet port or a first low-pressure device coupled thereto.

[0034] In some implementations, the method further includes adjusting the switchover valve to change from directing the flow of pressurized air from the air supply line to the low-pressure manifold to directing the flow of CO2 from the CO2 supply line into the low- pressure manifold.

[0041] FIG. 1 is a diagram of a fluid management system, according to one implementation.

[0042] FIG. 2 is a diagram of a fluid management system, according to one implementation.

[0043] FIG. 3 is a manifold of a fluid management system, according to one implementation.

[0044] Various objects, aspects, features, and advantages of the disclosure will become more apparent and better understood by referring to the detailed description taken in conjunction with the accompanying drawings, in which like reference characters identify corresponding elements throughout. In the drawings, like reference numbers generally indicate identical, functionally similar, and / or structurally similar elements.DETAILED DESCRIPTION

[0045] Referring generally to the figures, disclosed herein is a fluid distribution and manifold control system, according to various implementations.

[0046] In food service locations having a beverage dispensing system, components of the beverage dispensing system may include various fluid distribution elements. Some individual elements of the beverage dispensing system may receive a certain fluid to power the device or to produce a solution. For example, in some food service locations, carbon dioxide (CO2) is used in beverage dispensing systems. CO2 is used, for example, in carbonators to create a carbonated liquid (e.g., seltzer water for use in a soft drink dispensing machine). CO2 may also be used to power certain devices, such as pumps (e.g., bag-in-box pumps for pumping syrup to a beverage dispensing nozzle). The CO2 may be delivered to the various target locations / devices via a fluid manifold having individual valves and supply lines to each location / device.

[0047] Because CO2 is a finite resource, often delivered to a food service location in bulk containers, a risk exists that CO2 will run out and the beverage dispensing system may cease operation. Especially during times of supply chain inconsistency, food service locations may not be able to rely on consistent delivery of bulk CO2.

[0048] Provided in this disclosure is a solution to the problem of excessive CO2 usage and the risk of depleting CO2 in beverage dispensing systems. While some operations in a beverage dispensing system may require CO2 (e.g., the carbonator), other operations may not require CO2. For example, a bag-in-box pump or another low-pressure component may operate in a normal condition with a different pressurized fluid (e.g., air). Therefore, provided herein is a system and method for selectively delivering pressurized air to the components ofthe beverage dispensing system that can operate without CO2. One advantage of such a system is reduced usage of CO2.

[0049] An additional problem may occur when using pressurized air in components of a beverage dispensing system. Often, the air compressor, and the compressed air delivered therefrom, contains moisture / humidity. The humid air in the system causes accumulation of liquid in the system components, leading to failure of devices and inaccurate operation.

[0050] Provided herein is a filter-drier component of the air compression system. A fluid management system having a filter-drier and related components effectively dries the air to a dew point low enough to avoid excess moisture in the system components. One advantage of such a system is an effective and efficient fluid management system with a reduced usage of CO2.Example System

[0051] FIG. 1 shows a diagram of an example fluid distribution system 10, according to one implementation. The fluid distribution system 10 includes a CO2 source 100, an air source 200, a switchover valve 300, a high pressure manifold 400, and a low pressure manifold 500, as further described below.

[0052] The fluid distribution system 10 includes a CO2 source 100 with a supply line 102. The supply line 102 is coupled to an outlet 104 of the CO2 source 100. The CO2 source 100 may be a bulk tank for storing liquid CO2 or a high-pressure backup tank for storing gaseous CO2. As shown in FIG. 1, the CO2 source 100 of the fluid distribution system 10 includes both a bulk, of first, CO2 tank 106 and a high-pressure backup, or second, CO2 tank 108.Each of the bulk CO2 tank 106 and the high-pressure backup CO2 tank 108 have a respective outlet 104 coupled to a respective supply line 102. The supply line 102 is thus configured to deliver CO2 from the CO2 source 100 to other portions of the fluid distribution system 10, as further described below.

[0053] Each of the first CO2 tank 106 and the second CO2 tank 108 is coupled to and in fluid communication with a second switchover valve 110. The second switchover valve 110 is controllably movable (e.g., manual or automatic) to allow a flow of CO2 from either the first CO2 tank 106 or the second CO2 tank 108 to the high-pressure manifold 400. In some examples as described herein, the second CO2 tank 108 is provided as a back-up source of CO2 to the high-pressure manifold 400. For example, in normal operating conditions the high-pressure manifold 400 operates with the first CO2 tank 106 as the primary source ofC02. Should the first CO2 tank 106 run out of CO2, become inoperable, or otherwise fail to provide CO2 to the high-pressure manifold 400, then the second switchover valve 110 can redirect flow of CO2 from the second CO2 tank 108 to the high-pressure manifold 400. The switchover to the backup second CO2 tank 108 prevents the system from running completely out of CO2 and becoming inoperable in the event that the bulk first CO2 tank 106 runs out of CO2. This is particularly useful when supply chains fail to meet the demand for bulk-liquid CO2. Additionally, in some implementations, automatic switching to the backup second CO2 tank 108 prevents disruption in operation of the system. The system can continue to carbonate water and / or deliver product without requiring a manual switch to the backup tank.

[0054] In some examples, the first CO2 tank 106 contains a large volume of liquid CO2 and delivers an evaporated, gaseous form of CO2 to the CO2 supply line at a relatively high pressure (e.g., 90-110psi). In some examples, the second CO2 tank 108 contains a high- pressure gas CO2 (e.g., in the range of 200-1000psi).

[0055] The fluid distribution system 10 further includes a pressurized air source 200 with an air supply line 202 coupled to an outlet 204 of the pressurized air source 200. The pressurized air source 200 includes an air compressor 210 configured to compress and deliver ambient / environment air into the fluid distribution system 10 at a desired pressure. The air supply line 202 is thus configured to deliver pressurized air from the air compressor 210 to other portions of the fluid distribute system 10. The air compressor 210 is also provided for controlling the pressure of the pressurized air provided to the switchover valve 300 (and / or low-pressure manifold 500), as further described below.

[0056] The pressurized air source 200 further includes a filter-drier 212 coupled to the outlet 204 of the air compressor 210. The outlet filter-drier 212 is configured to reduce a liquid content of the air flowing through the system. In some examples, the air compressor is an oil-free air compressor, while in other examples the air compressor is an oil-run compressor.

[0057] In some examples, the output 204 of the air compressor 210 is coupled to an input of the filter-drier 212, while, in other implementations, the filter-drier 212 is integrated as a component of the air compressor 210. In some examples, the air compressor 210 outputs a volume of pressurized air to the filter-drier 212 where the liquid content of the air is reduced to a threshold dew point / humidity, and the air is then output from the filter-drier 212 and provided to the switchover valve 300 and the low-pressure manifold 500.

[0058] The filter-drier 212 is configured to remove at least one of condensation and impurities from the air flowing from the air compressor 210 to an inlet 304 of the switchover valve 300. The operation of the filter-drier 212 is controlled to modify at least one of a temperature, target dew point, humidity, or air purity of the air flowing to the switchover valve 300. For example, a controlled dew point will eliminate excess moisture and control the amount of acceptable moisture that could possibly be retained in the pneumatic components in the ABS and also the BIB pumps. In both scenarios this would prevent premature equipment failure. In some implementations, the filter-drier 212 includes a filter configured to reduce the dew point of the air flowing through the system to less than 3 °C.

[0059] The pressurized air source 200 further includes a tank drain 214 in fluid communication with the air compressor 210. The tank drain 214 is configured to drain a liquid collected in the air compressor 210. In some examples, the tank drain 214 can also be used to drain liquid collected at an adjacent reservoir. In some implementations, once the liquid collected in the air compressor 210 reaches a threshold liquid amount, the tank drain 214 automatically drains the collected liquid from the air compressor 210. In some implementations, the threshold amount of liquid is determined to provide for maximum air efficiency and minimize the need for regular maintenance. In some implementations, the tank drain 214 includes a siphon valve.

[0060] The fluid distribution system 10 further includes switchover valve 300 coupled to and in fluid communication with each of the CO2 supply line 102 and the air supply line 202 (e.g., with one or more elements disposed between the respective supply line and the switchover valve 300, such as a manifold). The switchover valve 300 is controllably movable to allow a flow from either the CO2 source 100 or the pressurized air source 200 through an outlet 302 of the switchover valve 300. The switchover valve 300 allows the fluid distribution system 10 to limit which portions of the fluid distribution system 10 are using CO2 from the CO2 source 100 by providing air from the pressurized air source 200 to those portions instead. The switchover valve 300 is selectively movable, allowing the system 10 to provide CO2 instead of pressurized air to those portions when desired, as further described below.

[0061] The fluid distribution system 10 further includes a controller 600 coupled to the switchover valve 300. In operation, the controller 600 is configured to move the switchover valve to allow either (i) a flow of CO2 from the CO2 source 100 to the low-pressure manifold 500, or (ii) a flow of pressurized air from the pressurized air source 200 to the low-pressure manifold 500.

[0062] High Pressure Manifold

[0063] The fluid distribution system 10 further includes a high-pressure manifold 400 coupled to and in fluid communication with the CO2 supply line 102 on one side 402 of the high-pressure manifold 400 (e.g., an inlet side of the high-pressure manifold). The other side 404 of the high-pressure manifold 400 (e.g., an outlet side of the high-pressure manifold) is coupled to and in fluid communication with the switchover valve 300. The high-pressure manifold 400 includes at least one at least one high-pressure outlet port 406. As shown in FIG. 1 , the high-pressure manifold 400 includes three high-pressure outlet ports 406, shown as 406a, 406b, and 406c, each directed to a different component or device of the fluid distribution system 10 requiring CO2.

[0064] The high-pressure manifold 400 of the fluid distribution system 10 includes a first high-pressure outlet port 406a coupled to a carbonator device 408. In some implementations, the system may include more than one carbonator device. The carbonator device 408 generally receives CO2 from the CO2 source 100 through the high-pressure manifold 400 and water from another source (e.g., a municipal water source) to create carbonated water or seltzer water. The carbonated water from the carbonator device 408 may then be directed to a beverage dispenser for use with a syrup in creating a beverage product. In some examples, the first high-pressure outlet port 406a is coupled to carbonator device 408 to provide food / beverage grade CO2 to a beverage product for making a carbonated beverage such as beer and / or soft drinks. In some implementations, the fluid distribution system further includes a controllable water inlet valve coupled to the water source. A water supply line may coupled the water inlet valve on one side and a carbonator device on the other.

[0065] The high-pressure manifold 400 of the fluid distribution system 10 includes a second high-pressure outlet port 406b coupled to a frozen carbonator device 414. For example, the second high-pressure outlet port 406b is coupled to at least one frozen carbonator device 414 to provide food / beverage grade CO2 to a frozen beverage product for making a carbonated frozen beverage. In some examples, the frozen carbonator device 414 also includes a compressed air input from the low-pressure manifold 500 to operate other components (e.g., the bag-in-box (BIB) pumps of the frozen carbonator device 414).

[0066] The high-pressure manifold 400 of the fluid distribution system 10 includes a third high-pressure outlet port 406c coupled to a clean-in-place supply line 410. The clean-in-place supply line 410 is coupled to a cleaning system for a bulk beverage storage container 412. Insome examples, the bulk beverage storage container 412 contains a concentrated beverage product / syrup that this provided to a beverage dispenser for making a beverage product. The clean-in-place supply line 410 directs CO2 to the bulk beverage storage container 412 to pressurize the bulk beverage storage container 412 and push all remaining syrup and sanitizer out of the bulk beverage storage container 412.

[0067] The fluid distribution system 10 further includes a gauge / regulator 401 that adjusts the pressure of the CO2 received from the CO2 supply line 102 to the high-pressure manifold 400. In some examples, the gauge / regulator 401 is controllable to automatically adjust the pressure of the CO2. In some examples, operation of the gauge / regulator 401 is controlled using a controller, (e.g., a wired / wireless controller 600). In some examples, the controller 600 (e.g., a microcontroller, PCB, or processor) receives pressure values from the gauge / regulator 401 and adjusts the gauge / regulator to cause the pressure of the CO2 to change to within a predetermined range (e.g., a minimum or maximum).

[0068] Low pressure manifold

[0069] The fluid distribution system 10 further includes a low-pressure manifold 500 coupled to and in fluid communication with the outlet 302 of the switchover valve 300. Thus, depending on the orientation of the switchover valve 300, the low-pressure manifold 500 may receive pressurized air from the pressurized air source 200 or CO2 from the CO2 source 100.

[0070] The low-pressure manifold 500 has at least one low-pressure outlet port 502. As shown in FIG. 1 , the low-pressure manifold 500 has three low-pressure outlet ports 502, shown as 502a, 502b, and 502c, each directed to a different component or device of the fluid distribution system 10 operable with either pressurized air or CO2.

[0071] Each of the first and second low-pressure outlet ports 502a, 502b are coupled, respectively, to an automated beverage system supply line 504a, 504b, leading to a first and second automated beverage system (ABS) 508a, 508b, respectively. The ABS (Automated Beverage System) 508 (including one or both of the first and second ABS 508a, 508b) is a beverage dispensing device that uses a fluid (e.g., CO2 or clean compressed air) to operate various devices. For example, the ABS 508 may use a fluid to operate an automated lift assembly which picks and drops beverage cups into a beverage conveyor. The ABS 508 may also use the same fluid for an ice gate cylinder which allows ice to automatically drop into the cups. The ABS 508 may also include a pneumatic control device powered by the fluid from the low-pressure manifold 500. The pneumatic control device of the automatedbeverage system 508 may include a component-level pressure regulator to adjust the pressure of air flow received at a component of the automated beverage system 508a, 508b.

[0072] The low-pressure manifold 500 of the fluid distribution system 10 includes a third low-pressure outlet port 502c coupled to a pump 506 (e.g., bag-in-box pump). In some implementations, the pump 506 is a bag-in-box (BIB) pump coupled to a concentrated beverage product / syrup source and a beverage dispenser for dispensing a beverage product including a concentrated beverage syrup.

[0073] The fluid distribution system 10 further includes a gauge / regulator 504 that adjusts the pressure of air flow received from the air supply line 202 to the low-pressure manifold 500. In some examples, the gauge / regulator 504 is used to adjust the air pressure down / up to the target pressure needed for low-pressure manifold 500 / (air) system components. It is contemplated that some low-pressure manifold 500 components may include componentlevel pressure regulators.

[0074] The gauge / regulator 504 is controllable to automatically adjust the pressure of the air flow. In some examples, operation of the gauge / regulator 504 is controlled using a controller 600 (e.g., a wired / wireless controller.) In some examples, the controller 600 (e.g., a microcontroller, PCB, or processor) receives pressure values from the gauge / regulator 504 and adjusts the gauge / regulator 504 to cause the pressure of the air to change to within a predetermined range (e.g., a minimum or maximum).

[0075] As described above, the controller 600 is configured to move the switchover valve to allow either (i) a flow of CO2 from the CO2 source 100 to the low-pressure manifold 500, or (ii) a flow of pressurized air from the pressurized air source 200 to the low-pressure manifold 500. For example, during a normal operation, the switchover valve 300 may be positioned to allow a flow of pressurized air from the pressurized air source 200 to the low- pressure manifold 500. However, when the system detects an error condition from the pressurized air source 200, the controller causes the switchover valve 300 to direct a flow of CO2 from the CO2 source 100 to the low-pressure manifold 500. The error condition may include, among other things, situations wherein (i) the controller / system detects no input of pressurized air (e.g., at the switchover valve 300), (ii) the controller / system detects a pressure of air lower than a minimum threshold value (e.g., detects via sensors at the air compressor 210, filter-drier 212, regulator 504 and / or the low-pressure manifold 500), (iii) the controller / system detects that the filter-drier 212 has been depleted or is non -function al (e.g.,that the flow of air is not maintained at the threshold dew point and / or temperature), or (iv) the controller / system detects that the tank drain 214 is non-functional (and / or the liquid amount in the air compressor 210 has exceeded the threshold liquid amount). In other implementations, the error condition is any other mechanical failure requiring the use of CO2 in the high-pressure manifold 400.Method of Operation

[0076] Further contemplated by this disclosure is a method of operation of a fluid distribution system 10. The method includes providing a fluid distribution system 10, including some or all the components and devices shown and described in FIG. 1. The fluid distribution system 10 may be installed in a food service location (e.g., a fast food restaurant or an event venue). The fluid distribution system 10 may be easy to monitor, operate, and maintain by users working in the food service location.

[0077] The method further includes directing a flow of CO2 from the CO2 source 100, through the supply line 102, and to the high-pressure manifold 400. For example, the fluid distribution system 10 may be installed such that CO2 is directed, either directly or indirectly, to the high-pressure manifold 400. The method further includes directing or providing a flow of CO2 from the high-pressure manifold 400 to the at least one high-pressure outlet port 406 and / or a first high-pressure device coupled thereto. For example, the flow of CO2 may be directed out of the high-pressure manifold 400 via one of the high-pressure outlet ports 406 to a carbonator device or a frozen carbonator device.

[0078] The method further includes filtering and drying a flow of pressurized air via a filter-drier device 212 in fluid communication with the pressurized air source 200. For example, a filter-drier 212 may be installed integral with, or adjacent to, the air compressor 210 to filter and dry the compressed air to a target purity or dew point. The method further includes directing the flow of pressurized air from the pressurized air source 200 (e.g., air compressor 210), through the air supply line 202, through the switchover valve 300, and to the low-pressure manifold 500.

[0079] The method further includes directing / providing a flow of pressurized air from the low-pressure manifold 500 to the at least one low-pressure outlet port 502 and / or a first low- pressure device coupled thereto. For example, the pressurized air may be directed to one or more devices capable of operation with a pressurized fluid (e.g., a low-pressure gas), such as a bag-in-box pump or a pneumatic actuator of an automated beverage system).

[0080] As described above, it may be desirable to switch the fluid distribution system 10 from delivering CO2 to the low-pressure manifold 500 and associated devices to delivering pressurized air to the low-pressure manifold 500. Utilizing pressurized air instead of CO2 conserves CO2 supply, which is advantageous during shortages of bulk CO2. However, the system is able to switch back to CO2 usage in the low-pressure manifold 500 as desired.

[0081] The method further includes adjusting the switchover valve 300 to change from (i) directing the flow of pressurized air from the air supply line 202 to the low-pressure manifold 500 to (ii) directing the flow of CO2 from the CO2 supply line 102 into the low-pressure manifold 500. For example, the adjustment step may be accomplished via a controller used for directing operation of the switchover valve 300. For example, during a normal operation of pressurized air in the low-pressure manifold 500, the controller 600 can adjust the switchover valve 300 to direct the flow of CO2 to the low-pressure manifold 500. This switchover operation may occur when the controller / system detects an error condition with the pressurized air source 200.

[0082] Such an error condition may occur when, for example, any one or more of the following occurs: (i) the controller / system detects no input of pressurized air (e.g., at the switchover valve 300 or at the regulator 504), (ii) the controller / system detects a pressure of air lower than a minimum threshold value (e.g., detects at the air compressor 210, the filterdrier 212, the regulator 504 and / or the low-pressure manifold 500), (iii) the controller / system detects that the filter-drier 212 has been depleted or is non-functional (e.g., that the flow of air is not maintained at the threshold dew point and / or temperature), or (iv) the controller / system detects that the tank drain 214 is non-functional (and / or the liquid amount in the air compressor 210 has exceeded the threshold liquid amount).

[0083] As shown and described in FIG. 1, the fluid distribution system 10 includes both a first, bulk CO2 tank 106 and a second, backup CO2 tank 108. Each of the first CO2 tank 106 and the second CO2 tank 108 are coupled to the second switchover valve 1 10. The method further includes adjusting the second switchover valve 110 to change from supplying a flow of CO2 to the high-pressure manifold 400 from the first CO2 tank 106 to supplying the flow of CO2 from the second CO2 tank 108 (and vice-a-versa).

[0084] In some implementations, the step of adjusting the second switchover valve 110 to direct the flow of CO2 from the high-pressure manifold 400 from the first CO2 tank 106 to the second CO2 tank 108 occurs when the controller 600 detects an error condition with thefirst C02 tank 106. Such an error condition may occur when, for example, the first CO2 tank 106 includes any one of: (i) the first bulk CO2 source / volume of CO2 contained in the first CO2 tank 106 has been depleted; (ii) the controller / system detects no input of CO2 (e.g., at the second switchover valve 110) or at the regulator 112), or (ii) the controller / system detects a pressure of the flow of CO2 is lower than a minimum threshold value (e.g., at the high- pressure manifold 400).Example Systems

[0085] FIG. 2 shows another example fluid distribution system 20, similar to the fluid management system 10 shown in FIG. 1, except as described below. The fluid management system 20 in FIG. 2 includes representative images for various system elements (e.g., the CO2 bulk tank and CO2 backup tank).

[0086] Furthermore, FIG. 2 includes labeled devices coupled to each of the ports of the high and low pressure manifolds. For example, the high-pressure manifold 400 of FIG. 2 includes three high-pressure outlet ports 406. Two of the high-pressure outlet ports 406 are coupled to carbonator devices (labeled “carbonator A” 408a and “carbonator B” 408b), while one of the high-pressure outlet ports 406 is coupled to a frozen carbonated beverage machine 414 (labeled “FCB”).

[0087] The low-pressure manifold 500 includes many low-pressure outlet ports 502. For example, the low-pressure manifold 500 of FIG. 2 includes low-pressure outlet ports 502 for two different automated beverages system devices (labeled “ABS 1” 508a and “ABS 2” 508b). The low-pressure manifold 500 of the system 20 further includes low-pressure outlet ports 502 for a frappe machine, a ketchup pump, BIB pumps, mixed-in sugar tea dispensers, and BIB pumps for frozen carbonated beverages. Each of these devices are configured to be powered by fluid from the low-pressure manifold 500 - whether that fluid is air from the pressurized air source 200 or CO2 from the CO2 source 100. This disclosure contemplates a variety of low- and high-pressure devices coupled to and receiving fluid from each of the low-pressure manifold 500 and the high-pressure manifold 400, beyond that shown in FIG. 2.

[0088] FIG. 3 shows an example manifold system 30 for a fluid distribution system (e.g., a manifold for the systems 10, 20 of either FIG. 1 or FIG. 2). The manifold 30 of FIG. 3 may be mounted or installed on a wall or piece of equipment in a food service location. The manifold 30 includes an input port for CO2 on one side 402 of the high-pressure manifold 400, which is disposed on one side of the switchover valve 300. The manifold 30 includes aninput port for pressurized air at the air supply line 202 on the other side of the switchover valve 300. Either fluid source (e.g., CO2 or pressured air) may be placed adjacent or distant to the manifold 30 (e.g., from a back room coupled by a hose / tube). The manifold 30 may further include water input and related valves / tubing.

[0089] The manifold 30 is color-coded and labeled for ease of use. For example, a teal / green / blue color is used for the high-pressure manifold 400, as is standard in the industry. A yellow color is used for the low-pressure manifold 500. This allows a user to easily identify which portion of the manifold 30 connects to which components. It also allows for ease of use when switching certain components on / off (e.g., during maintenance) or when switching between fluid sources.

[0090] The switchover valve 300 shown on the manifold 30 in FIG. 3 is configured to allow pressured air from the air supply line 202 to enter the low-pressure manifold 500 for use in various devices coupled to the low-pressure outlet ports 502. This is shown by the valve direction shown in FIG. 3, wherein the prongs of the switchover valve align the air supply line 202 with the switchover valve outlet 302. However, the switchover valve 300 can be switched as described herein so that CO2 from the high-pressure manifold 400 instead enters and is utilized by the low-pressure manifold 400 (e.g., along with the use of a regulator). This may be accomplished by manual turning of the switchover valve 300 or by a control system and automated motion control of the switchover valve 300.Configuration of Certain Implementations
