The present invention discloses a regulable pressure relief valve for a draft beer fresh-keeping keg, comprising a valve body housing, a first compression spring, a mushroom-shaped ejector rod, a second compression spring and a pressure exerting block. Said first compression spring, ejector rod, second compression spring and pressure exerting block are coaxially distributed; the ejector rod comprises a retractable rod and a mushroom head; the first compression spring is put on the retractable rod and the two ends of the first compression spring is stressed between the bottom of the mushroom head and the valve body housing; the two ends of the second compression spring is stressed between the top of the mushroom head and the pressure exerting block; a pressure regulation at the top of the retractable rod is realized by exerting a pressure on the pressure exerting block and thus realize the pressure regulation function.

The present invention relates to a method, apparatus and universal container for natural carbonation of beverages, which will be used in the food industry, in particular in the production of beer, sparkling wines and carbonated fruit drinks. The method of naturally occurring carbonation of beverages involves the operations of feeding with fermenting substrate, adding water, adding yeast, fermenting the resulting liquid mixture. The fermentation is carried out in a specialized container at an optimum temperature of 8° C. to 23° C., depending on the yeast species. The fermentation process lasts for 3 to 4 days and is accompanied by an increase in container pressure to 2 bar.

A dispensing system including: a pressure vessel with an inlet and an outlet; a first CF Valve coupled to the inlet; a second CF Valve coupled to the outlet; a bag with elements in the bag coupled to the outlet and located inside the pressure vessel; and a pressure source coupled to the first CF Valve where the first CF Valve pressurizes the pressure vessel via the pressure source to transport elements in the bag to the second CF Valve via the outlet and the second CF Valve dispenses the elements to a dispensing area.

A carbonated water dispenser comprises a carbonator with a water inlet and a carbonated water outlet. A backflow preventer module is fluidically coupled to the water inlet and comprises a check valve and a thermal mass flow meter. The thermal mass flow meter is configured to communicate a first signal based on a measured amount of heat transferred from a heater to a temperature sensor by a flow of a fluid through the backflow preventer module. A shut-off valve is fluidically coupled between the carbonated water outlet and a nozzle. The shut-off valve is configured to allow or prevent fluid flow from the carbonated water outlet to the nozzle base on a control signal. A controller is configured to detect a backflow condition based on the first signal and generate the control signal to configure the shut-off valve to prevent dispensing carbonated water upon detection of the backflow condition.

Provided is a liquid supply system with which it is possible to perform quality control of a liquid provided by the system. A liquid supply system (101) that pumps a liquid in a storage container (10) through a supply tube (30) and dispenses the liquid from a liquid dispensing spout of a dispensing device (50), said liquid supply system (101) comprising: a jetting prevention device (110) that has a liquid inlet (111), a liquid outlet (112), and a float (116) for closing the liquid outlet due to inflow of air from the liquid inlet, thereby preventing jetting of pressurized air from the liquid dispensing spout, and provides cleaning or no cleaning inside of a conduit in the liquid supply system; a liquid absence detection device (120) that has a no-liquid/liquid passing sensor (122) for detecting that the liquid in the storage container is gone, and sends empty storage container information; and a transmission device (130) that has a control unit (131) for carrying out control of information transmission to a communication line (200).

A removable liquid transport assembly configured to be readily installed in and removed from a liquid dispenser to permit the liquid dispenser to be readily sanitized. The removable liquid transport assembly preferably includes a liquid manifold, a valve assembly and a pump head. The removable liquid transport assembly is configured such that liquid can flow in a first direction through the removable liquid transport assembly to permit a liquid to be dispensed from a liquid dispenser and liquid can flow in a second direction back to a liquid storage container to prevent damage to one or more components of the liquid dispenser.

A system for dispensing a beverage from a pressurized beverage container, the system including an interface having a housing, a tap assembly, a dip tube, a carry handle, and a receiving section. The housing is configured to fasten to a neck portion of a beverage container. The tap assembly rigidly extends from the housing and has a tap handle and a passageway configured to allow a beverage to pass through the tap assembly and out a dispensing end of the tap assembly when the tap handle is activated. The dip tube extends from a first side of the housing and is coupled to the passageway of the tap assembly. The carry handle extends from the housing. The receiving section is configured to receive a pressure regulator and includes an opening extending from a second side of the housing through the first side of the housing.

A bag-in-keg container for a carbonated beverage has a container body C, a flexible bag B within the container body, and a valve closure V attached to the container body. The valve closure includes a gas inlet port (11), a liquid dispensing port (12), and spring-loaded valve member (6) to sealably close the gas inlet and liquid dispensing ports. An adapter (20) sealingly attached to the flexible bag B incorporates a bag PRV (26) to vent gas pressure from within the flexible bag. A container PRV (40) vents gas pressure from between the container body C and the flexible bag B. The bag PRV has a valve shuttle with one side exposed to gas pressure within the flexible bag B and an opposite side exposed to gas pressure within a sealed plenum chamber (37). The bag PRV therefore operates at a fixed pressure independent of the differential pressure between the bag and the outer container. This solves the problem of venting excess pressure within the keg whilst still allowing the dispensing gas to achieve the equilibrium.
