U.S. Pat. No. 7,451,895 discloses a liquid dispensing system comprising a container containing at least one flexible bag. A first liquid is contained in the bag. A manifold chamber is in communication with the bag via a first metering orifice, and with the interior of the container via a second metering orifice. A second liquid is introduced under pressure into the container. The thus introduced second liquid serves to pressurize the first liquid in the bag, with the first and second metering orifices serving to respectively admit metered amounts of the first and second liquids into the manifold chamber for combination into a liquid mixture dispensed through an outlet. The metering orifices constrict flow and are prone to blockage when processing syrups and the like with elevated viscosities and/or high levels of suspended solids.
This disclosure relates generally to liquid delivery systems, and is concerned in particular with a portable system capable of delivering an on demand high ratio mixture of at least two liquids, with at least one of the liquids having an elevated viscosity and/or a high level of suspended solids. Further, this disclosure illustrates a cleaning (e.g., cleaning, sanitizing, and/or rinsing) system for a drink dispensing device.
In accordance with one aspect of the present disclosure, a liquid dispensing system comprises a container enclosing a chamber. A flexible bag in the chamber contains a first liquid. First and second conduits are located in the chamber. The first conduit connects the chamber to an outlet port in the container wall, and the second conduit connects the bag to the first conduit.
A supply source introduces a pressurized second liquid into the chamber. The first conduit serves to direct an exiting flow of the second liquid from the chamber to the outlet port, with the pressurized second liquid serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid.
The first liquid may typically comprise a high viscosity beverage concentrate, and the second liquid may comprise municipal tap water.
The supply source of the liquid dispenser system may include a constant flow valve located externally of the container.
The liquid dispenser may further comprise check valves in one or both of the first and second conduits for preventing a reverse flow of liquid into the chamber.
The first conduit may include a metering orifice. However, the second conduit does not include any flow restriction devices such as metering orifices.
The first conduit may communicate with an upper region of the chamber, and the pressurized liquid may be introduced into a lower region of the chamber via an inlet port in the container.
A third open ended bypass conduit may be arranged between the container wall and the bag, and may extend from the lower region to the upper region of the chamber.
A liquid dispensing system in accordance with another aspect of the present disclosure may comprise a container enclosing a chamber having upper and lower region.
A flexible bag in the chamber extends vertically between the upper and lower regions.
A first liquid is contained in the bag, and first, second and third conduits are arranged in the chamber. The first conduit leads to an outlet port in the container wall. The second conduit connects the bag to the first conduit.
A supply source introduces a pressurized second liquid into the chamber and separately into the third conduit for delivery to the first conduit. The first conduit serves to direct an exiting flow of the second liquid to the outlet port, with the pressurized second liquid in the chamber serving to collapse the bag and expel the first liquid contained therein via the second conduit to the first conduit for mixture with the exiting flow of the second liquid.
The pressurized liquid may be introduced into a T-fitting in the chamber. The T-fitting has one branch communicating with the third conduit and another branch communicating with the chamber.
An exemplary embodiment of a liquid delivery system embodying aspects of the present disclosure is depicted in
The system comprises a container 10 enclosing a chamber 12. The container may advantageously comprise a tubular wall 14 closed at its opposite ends by caps 16.
At least one flexible and collapsible bag 18 is contained in the chamber 12. The bag 18 typically will contain a first liquid 20, which may comprise a high viscosity beverage concentrate, for example a tea concentrate.
First and second conduits 22, 24 are located in the chamber 12. The first conduit 22 may typically include an elbow fitting 23, one end of which communicates with an outlet port 26 in the container wall 14. The outlet port 26 may lead to an on/off faucet 28 or other like dispenser. The dispenser may be manually operable, as shown, or of any known remotely operable type.
The first conduit 22 may additionally include an orifice 30 fitted to the opposite end of the elbow fitting 23, and a check valve 32. It will thus be seen that the first conduit 22, which as shown includes the elbow fitting 23, orifice 30 and check valve 32, provides a connection between the chamber 12 and the outlet port 26, which in turn communicates with the dispensing faucet 28.
The second conduit 24 may include an L-shaped fitting 34 closing the bottom open end of the bag 18, and a flexible tube 36 communicating at its opposite ends with the fitting 34 and the interior of the elbow fitting 23.
A check valve 38 may be included in the tube 36. The second conduit 24, which includes the fitting 34, tube 36 and check valve 38 thus connects the bag 18 to the first conduit 22, with such connection being achieved entirely within the confines of chamber 12.
At least one and advantageously both of the check valves 32, 38 may comprise so called “duckbill valves”, an exemplary embodiment of which is depicted in
With reference to
The flexible tube 36 provides a smooth continuous connection between the fittings 34 and 23, without any internal restrictions of the type provided by metering orifices or the like.
A supply source 48 serves to introduce a pressurized second liquid 50 into the chamber 16. The second liquid may typically comprise tap water drawn from a municipal supply system.
Advantageously, the supply source 48 may include a constant flow valve 52 connected by means of a dry break quick connect coupling 54 to a nipple 55 projecting from an inlet port 56 in the container wall 14. As can best be seen in
As herein employed, the term “constant flow valve” means a flow control valve of the type described, for example, in any one of U.S. Pat. Nos. 7,617,839; 6,026,850 or 6,209,578, the descriptions of which are herein incorporated by reference in their entirety. These types of valves are normally closed, are opened in response to pressures exceeding a lower threshold level, are operative at pressures between the lower threshold level and an upper threshold level to deliver liquids at a substantially constant pressures, and are again closed at pressures above the upper threshold level.
When the faucet 28 is opened, the first conduit 22 serves to direct an exiting flow of the pressurized second liquid 50 (water) from the chamber 12 through the outlet port 26. The pressurized second liquid in the chamber 12 also serves to collapse the bag 18, causing the first liquid 20 (beverage concentrate) to be expelled via the second conduit 24 for injection into the exiting flow of the second liquid in the elbow fitting 23 of the first conduit 22. Injection of the first liquid into the exiting flow of the second liquid resists layering of the first liquid and thereby promotes mixture of both liquids.
In accordance with a second aspect of the present disclosure, and as depicted in
In accordance with a third aspect of the present disclosure, as depicted in
With this arrangement, the second liquid 50 is delivered to conduit 60 separately from that being delivered to the chamber 12.

The length of the tube orifice will dictate the flow rate of the active ingredient in the bag and therefore the ratio of the water to the active ingredient. For example with Sanitizer A the tube orifice length is 13.5 inches based on the viscosity of Sanitizer A this will create a ratio of 514 to 1 (parts water to parts active) at a 0.50 oz. per second total mixed product flow rate and 341 to 1 (parts water to parts active) at a 0.9 oz. per second total mixed product flow rate. With Cleaner B the tube orifice length is 9.5 inches based on the viscosity of Cleaner B this will produce a ratio of 60 to 1 (parts water to parts active) at a 0.50 oz. per second total mixed product flow rate and a ratio of 32 to 1 (parts water to parts active) at a 0.90 oz. per second flow rate. If the ratio of water to active is to be reduced, the flow rate of the active is increased (stronger mixed product) by reducing the length of the tube orifice and if the ratio of water to active is to be increased, the flow rate of the active is reduced (weaker mixed product) by increasing the length of the tube orifice.
The interior pressure is the same on both canisters but the flow rate is different on each, due to the length of the tube. This allows for different application rates but to be empty on the same day to minimize re-installation, i.e. both canisters are empty at the same time. In various example, the need to replace canisters is predictable, a certain day, X days hence. No continuing monitoring is necessary. No wasted labor and no human error.

The water source (ie: city water) enters the system through and passes by a pressure regulator through a T the water is directed to the two CFiVes that control the UHR system, the CFiVe controls the pressure of the water to the targeted Pressure into the Canisters, the water enters the canister through the Manifold water inlet and pressurizes the bag of active ingredient which pushes active ingredient through the tube orifice into the mixing manifold where it mixes with water and flows back into the machine through the flow meter/total dissolved solids sensor and into the manifold via the incoming sanitation solenoid, one the cleaning or sanitation mixed solution is in the solenoid manifolds it then passes through each of the various solenoids downstream to sanitize/clean that particular circuit in the system.
In
For ease of retrofit the cleaning canisters can be mounted outside the machine (behind, below, above), the same water that is utilized inside the machine can be routed out the machine and into a Tee into the CFiVes. When the CFive is actuated the water flows into the canister from the respective CFiVe, the mixed product exits the canister and flows to a T and into the back of the machine to the Solenoid Manifold inside the machine or into the chosen flow path (one or more) that will be cleaned/sanitized within the machine.

Existing systems for cleaning beverage, ice cream, ovens and other food equipment are very reliant on labor and efficacy of the cleaning can be impacted by the employee's calculation of dilution factor, remembering/choosing to run the daily, hourly and weekly cleaning cycles. This is subject to serious error and with increased focus on cleaning for quality and safety and with increased awareness by recent global events, restaurants, convenient stores, fast food, institutional purveyors and regulators need better guarantees that equipment is being cleaned appropriately and to the standards require.
Additionally, there is an opportunity for much improved environmental impact and business system impact by providing high and ultra-high ratio concentrates that are diluted on demand reducing package size, shipping size and frequency and dramatically reducing the carbon footprint and costs of delivering cleaning, sanitizing, descaling and other concentrates.
In an existing bucket and pump system measured chemicals are poured into bucket and filled with water to correct level mark on bucket and stir to mix. This bucket is then carried to the front of machine and pump through to sanitize. There are many chances for error in measurement of chemical and/or water in this procedure. Further skin contact of chemicals, carry bucket/spills etc. is problematic. In addition to a ratio control problem, there is a time issue and quality control issues. For example, time between cleaning, as well as time for solution to be present in plumbing to be effective. Furthermore, employee may just skip doing it as it is difficult to do especially in a crowded store. Another issues, is inconsistences on when and how the device is cleaned. For example, a first employee may clean the system at the appropriate time but not at the appropriate ratios. A second employee may not clean the system at all. While, a third employee may clean the system at the appropriate times with the appropriate ratio. In another system, a ChemStation type—fill bucket with chemicals and water each by weight has the same issues noted above. In another example, an Ecolab type may be done by filling a bucket by timed run of peristaltic pump has the same issues noted above. In addition, weekly service to “top off” large storage tank containing a mixed solution—gravity feed to bucket has the same issues noted above.
NOTE: none of the systems now in service have the Clean In Place feature, i.e. UHR concentrate internal to the machine using the same city water supply—does not require an additional water connection to the machine, and machines own computer will turn on and off as required. These may all be in one or more embodiments disclosed in this document.
A Clean in Place method of sanitation that is internal to the machine being cleaned. One or more Ultra High Ratio canisters of concentrated chemical cleaning liquid, may be calibrated to perform the cleaning cycle for a period weeks or months without having to be replaced. The canisters are mounter internal to the machine, plumbed into the machine's water supply source to be cycled on and off as necessary by the machines computer system. When the sealed, single use, canister is empty the machine may stop serving until the empty canister[s] is disconnected at the dry break and is replaced with a new cartridge.
Note the same clean in place system can be situated beside, behind, beneath the machine or even in the back-room of the facility. It can be automatically run by its own controller/computer/timer in the same way the internal-inside machine is run.
One example is a double bag design. The canister may be constructed with a double bag inside a ridged body if there is a chemical compatibility. The interior bag contains the cleaning chemicals and intern is contained in outer bag. The water to supply the pressure and to mix with the solution is fed in between the two bags and expands outward to be contained by the outer ridged body. There is a vent in the ridged body to allow the air to escape as the bag is filled. The benefit of the double bag system is that there is a vacuum between the two bags and there is no change of air being compressed changing the ratio of the concentrate to water mixture.
Another example is a single bag design. The single bag design uses a bag inside a ridged canister. The water supply fills the canister and compresses the bag.
The canister may be assembled with all components built into the cap—check valves, mixing chamber, orifice, etc. This makes for simple assembly and reduced costs (this is different than the current UHR design). Additionally, there may be dry breaks in the canister that allow for a dry/quick connect on the inlet water and the diluted outbound solution. This is an advantage for when the canister is replaced when it is empty. The inlet and outlet dole feature is designed so that it can be placed at any angle to accommodate where it resides in the machine. Dole fittings would allow a universal installation as the supply/discharge would be in any direction.
A system can have single or multiple canisters to allow for different chemicals (i.e.: cleaner, sanitizer, descaler) and also to have multiple different cycles utilizing one or more of the chemicals for varying different lengths of time as needed to clean for different products (i.e.: coffee, milk, juice, ice cream, steam oven, etc.) Multiple canisters would be an advantage because the cleaning for different products [juice or milk] may require a different chemical or a different time to flush.
All of the cycles are controlled either through the controller of the existing equipment or by an external controller/computer built into the CFV-UHR-CIP kit. For example, a smoothie machine may run 4 hour sanitation, daily clean (short) and weekly clean (long) cycles. The built in system will shut down the machine every four hours and run the four hour cycle, and once a day to run the daily cycle and then once a week for the weekly cycle. The machine will be in operable during the cleaning cycle and will automatically be flushed with clean water after the cycle. Furthermore, there is a Total Dissolved Solids meter and/or sensors that measures the dissolved solids in the city water and then the dissolved solids in the mixed chemical. This will tell the system (whether internal or external) whether the chemical amount is on target and will provide a sold out feature to notify of chemical replacement. Also, the “sold out” feature can be utilized to shut down the entire machine so there is no way for an employee to allow a “dirty” machine to dispense/cook/mix product.
The canisters can be designed to be single use or recyclable. However, they are designed to be plug and play to the system (again through the dry break connections). The dry break connections are “pokey-oked” so that the operator/employee can NOT connect the inlet to the outlet in error and can NOT connect the wrong chemical cartridge to the wrong inlet/outlet port (i.e.: cleaner to the sanitizer port).
The design of the orifice tube connection to the bag and to the manifold provides a streamline approach that doesn't allow kinking or compression in the canister.
Because the inlet water is controlled by an electronically actuated CFValve it provides a constant pressure and ability to electronically actuate based on time of day and length of desired clean. Furthermore the addition of the CFiVe for the flush and TDS circuit allows the system to be automatically flushed after use and fore (or force) the TDS sensor to take a baseline water dissolved solids reading to apply the Delta calculation to ensure the proper dilution/strength of the chemical and sold out feature.
In light of the foregoing, it will now be appreciated by those skilled in the art that the present disclosure embodies a number of significant advantages, the foremost being the automatic pressure responsive control of fluid flow between a variable pressure source and an applicator from which the fluid is to be applied in a substantially uniform manner. The regulating valve is designed for low cost mass production, having a minimum number of component parts, the majority of which can be precision molded and automatically assembled.
In one example, a regulating valve for maintaining a substantially constant flow of fluid from a variable pressure fluid supply to a fluid outlet includes: a housing having axially aligned inlet and outlet ports adapted to be connected respectively to the fluid supply and the fluid outlet, and a diaphragm chamber interposed between the inlet and outlet ports, the inlet port being separated from the diaphragm chamber by a barrier wall, the barrier wall having a first passageway extending therethrough from an inner side facing the diaphragm chamber to an outer side facing the inlet port; a cup contained within the diaphragm chamber, the cup having a cylindrical side wall extending from a bottom wall facing the outlet port to a circular rim surrounding an open mouth facing the inner side of the barrier wall, the cylindrical side and bottom walls of the cup being spaced inwardly from adjacent interior surfaces of the housing to define a second passageway connecting the diaphragm chamber to the outlet port; a resilient disc-shaped diaphragm closing the open mouth of the cup, the diaphragm being axially supported exclusively by the circular rim and having a peripheral flange overlapping the cylindrical side wall; a piston assembly secured to the center of the diaphragm, the piston assembly having a cap on one side of the diaphragm facing the inner side of the barrier wall, and a base suspended from the opposite side of the diaphragm and projecting into the interior of the cup; a stem projecting from the cap through the first passageway in the barrier wall to terminate in a valve head, the valve head and the outer side of the barrier wall being configured to define a control orifice connecting the inlet port to the diaphragm chamber via the first passageway; and a spring in the cup coacting with the base of the piston assembly for resiliently urging the diaphragm into a closed position against the inner side of the barrier wall to thereby prevent fluid flow from the inlet port via the first passageway into the diaphragm chamber; and the spring being responsive to fluid pressure above a predetermined level applied to the diaphragm via the inlet port and the first passageway by resiliently accommodating movement of the diaphragm away from the inner side of the barrier wall, with the valve head on the stem being correspondingly moved to adjust the size of the control orifice, thereby maintaining a substantially constant flow of fluid from the inlet port through the first and second passageways to the outlet port for delivery to the fluid outlet.
In another example, a regulating valve for controlling the flow of fluid from a variable pressure fluid supply to a fluid outlet includes: a housing having axially aligned inlet and outlet ports adapted to be connected respectively to the fluid supply and the fluid outlet, and a diaphragm chamber interposed between the inlet and outlet ports, the inlet port being separated from the diaphragm chamber by a barrier wall, the barrier wall having a first passageway extending therethrough from an inner side facing the diaphragm chamber to an outer side facing the inlet port; a cup contained within the diaphragm chamber, the cup having a cylindrical side wall extending from a bottom wall facing the outlet port to a circular rim surrounding an open mouth facing the inner side of the barrier wall, the cylindrical side and bottom walls of the cup being spaced inwardly from adjacent interior surfaces of the housing to define a second passageway connecting the diaphragm chamber to the outlet port; a resilient disc-shaped diaphragm closing the open mouth of the cup, the diaphragm being supported exclusively by the circular rim and having a peripheral flange overlapping the cylindrical side wall; a piston assembly secured to the center of the diaphragm, the piston assembly having a base projecting into the interior of the cup; a spring in the cup coacting with the base of the piston assembly for resiliently urging the diaphragm into a closed position against the inner side of the barrier wall to thereby prevent fluid flow from the inlet port via the first passageway into the diaphragm chamber; and the spring being responsive to fluid pressure above a predetermined level applied to the diaphragm via the inlet port and the first passageway by resiliently accommodating movement of the diaphragm away from the inner side of the barrier wall, thereby accommodating a flow of fluid from the inlet port through the first and second passageways to the outlet port for delivery to the fluid outlet.
In another example, the control orifice is defined by frusto conical surfaces on the valve head and the outer side of the barrier wall. In another example, the cross sectional area of the control orifice is less than the cross sectional area of the first passageway throughout the range of movement of the valve head in response to fluid pressure applied to the diaphragm. In another example, the regulating valve further includes a vent passageway leading from the interior of the cup to the exterior of the housing. In another example, the housing is exteriorly provided with a deflecting surface adjacent to the outlet of the vent passageway, the deflecting surface being configured and arranged to direct fluid escaping from the interior of the cup in the general direction of fluid flowing through the valve, but angularly away from the valve axis. In another example, the base of the piston assembly is spaced from the bottom wall of the cup by an open gap, and wherein the spring means comprises a coiled spring bridging the gap and in contact at its opposite ends with the bottom wall and the base. In another example, the piston assembly is centered within the cup solely by the resilient support provided by the diaphragm. In another example, the housing is comprised of mating plastic inlet and outlet sections, the sections being formed by injection molding and being permanently assembled one to the other by sonic welding. In another example, the cap and base of the piston assembly are each injection molded of plastic and joined one to the other by sonic welding, with a central portion of the diaphragm held there between.
In one example, a dispensing device includes a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure, and a solenoid which interacts with the outlet stream. In addition, the dispensing device may have: at least one of the inlet stream and the outlet stream being a carbonated water; the first pressure is greater than the second pressure; a size of the solenoid is reduced based on a reduction in pressure from the first pressure to the second pressure; a size of the solenoid is reduced based on the valve; the inlet stream is a utility line; the orifice is fixed; the orifice is adjustable; the orifices are both fixed and adjustable; and the valve is a CF Valve. The CF Valve is a regulating valve for maintaining a substantially constant flow of fluid from a variable pressure fluid supply to a fluid outlet, the CFValve may including one or more of: a) a housing having axially aligned inlet and outlet ports adapted to be connected respectively to the variable fluid supply and the fluid outlet; b) a diaphragm chamber interposed between the inlet and the outlet ports, the inlet port being separated from the diaphragm chamber by a barrier wall, the barrier wall having a first passageway extending therethrough from an inner side facing the diaphragm chamber to an outer side facing the inlet port; c) a cup contained within the diaphragm chamber, the cup having a cylindrical side wall extending from a bottom wall facing the outlet port to a circular rim surrounding an open mouth facing the inner side of the barrier wall, the cylindrical side and bottom walls of the cup being spaced inwardly from adjacent interior surfaces of the housing to define a second passageway connecting the diaphragm chamber to the outlet port; d) a resilient disc-shaped diaphragm closing the open mouth of the cup, the diaphragm being axially supported by the circular rim and having a peripheral flange overlapping the cylindrical side wall; e) a piston assembly secured to the center of the diaphragm, the piston assembly having a cap on one side of the diaphragm facing the inner side of the barrier wall, and a base suspended from the opposite side of the diaphragm and projecting into the interior of the cup; f) a stem projecting from the cap through the first passageway in the barrier wall to terminate in a valve head, the valve head and the outer side of the barrier wall being configured to define a control orifice connecting the inlet port to the diaphragm chamber via the first passageway; and g) a spring device in the cup coacting with the base of the piston assembly for resiliently urging the diaphragm into a closed position against the inner side of the barrier wall to thereby prevent fluid flow from the inlet port via the first passageway into the diaphragm chamber, the spring device being responsive to fluid pressure above a predetermined level applied to the diaphragm via the inlet port and the first passageway by accommodating movement of the diaphragm away from the inner side of the barrier wall, with the valve head on the stem being moved to adjust the size of the control orifice, thereby maintaining a constant flow of fluid from the inlet port through the first and second passageways to the outlet port for delivery to the fluid outlet.
In another example, the dispensing device may further include: a dispensing unit including one or more flavor units and one or more water units where each of the one or more flavor units include a transportation unit, the transportation unit including a barrier element with one or more openings; a blockage device configured to close the one or more openings to prevent a flow from at least one of the one or more flavor units; and/or a movement device configured to move the blockage device to a first position relative to the one or more openings which allows for a passage of one or more fluid elements and one gaseous elements through the one or more openings in the blockage device.
The dispensing device may further include a carbonated unit. In another example, the movement device is a magnet. In another example, the movement device is an electro-magnet. In another example, the dispensing device may have at least one of the one or more flavor units may be selectable. In addition, the at least one of the one or more flavor units may be automatically selectable.
