Beverages such as beer and soda which contain carbon dioxide or other gases may degrade in quality when subjected to atmospheric pressure, oxygen, and/or light. It may be desirable to store such beverages in containers which prevent exposure to these conditions. An aluminum can is one such container but is associated with the problem of resealing the can after breaking the seal. The described utilities provide for resealing, pressurizing, and/or dispensing from an aluminum can or similar beverage container.

An NO-accumulation apparatus, method and use, comprising: a container (120) defining a cavity for accommodating a liquid (105), an inlet (150) for feeding the liquid into the container (120) and an outlet (151) for delivering the liquid from the container (120) to a bath unit; an NO-gas dissolving unit (140) for dissolving gaseous NO in the liquid (105) to produce an NO-containing liquid, wherein the NO-gas dissolving unit (140) is arranged in the container (120) and/or forms a part of the container (120); and an NO-gas port (110) in fluid communication with the NO-gas dissolving unit (140), wherein the NO-gas port (110) is adapted for coupling, particularly for releasably coupling, with an NO-gas supply, whereby the apparatus further comprises means for decoupling the inflow of NO to the liquid (105) within the container from the removal of the NO-containing liquid (NO-decoupling means), so that the removal of the NO-containing liquid is inhibited, when the NO is flowing into the liquid, and also the NO inflow is inhibited when the NO-containing liquid is removed from the container (105).

An integrated device including a vessel, a gas reservoir, a pressure regulation device, a primary filter, and a tap assembly. The vessel is configured to contain a beverage. The gas reservoir is configured to supply pressurized gas within the vessel. The pressure regulation device is configured to maintain an infusing pressure within the vessel and also a dispensing pressure within the vessel. The primary filter is configured to hold solid brewing media, to fit inside the vessel, and to be removable from the vessel. The tap assembly is configured to dispense the beverage from the vessel. Methods are also disclosed.

A gas injection system for injecting a gas into a liquid to form a solution includes a flow channel that conveys a liquid from an upstream inlet configured to receive the liquid and a downstream outlet configured to dispense the solution, sparger positioned in the flow channel, a solution pressure detection device configured to sense a pressure of the solution in the flow channel, and a liquid valve configured to regulate flow of the liquid in the flow channel based on the pressure sensed by the solution pressure detection device. The sparger is configured to inject the gas into the liquid through the porous surface as the liquid flows across the surface.

A material mixing and supplying system is provided. The material mixing and supplying system includes a feeding module, at least three mixing and supplying barrels, a supply module, and a control unit, wherein the three mixing and supplying barrels are capable of mixing and supplying the mixed material. The supplying time of the mixed material is greater than a sum of the feeding time and the mixing time. A total operation number of the at least three mixing and supplying barrels is determined by a set amount of mixed material to be supplied by the material mixing and supplying system, and a total time to finish supplying the set amount of mixed material is determined by the total operation number.

A system for preparing and dispensing a nitrogen infused beverage is provided. The system includes a beverage concentrate container in fluid connection, through a first flow controlling point, with a nitrogenated beverage liquid mixing point, a nitrogenated water supply in fluid connection, through a second flow controlling point, to said nitrogenated beverage liquid mixing point, wherein said nitrogenated water supply includes a water supply in fluid connection with a liquid/gas contactor unit having a controlled pressurized supply of a gas includes at least 50% by weight nitrogen supplied thereto, and a nitrogen infused beverage line in fluid connection from the nitrogenated beverage liquid mixing point to a beverage faucet of a faucet tower, wherein the beverage faucet is a faucet such that the infused beverage in the nitrogen infused beverage line remains under pressure during dispense of the beverage from the faucet. The beverage may be any non-carbonated liquid and in one embodiment the beverage is coffee. The dispensed N.sub.2 or N.sub.2/CO.sub.2 gas infused chilled coffee has a unique appearance and enhanced flavor and aroma.

Ultrafine bubbles with a diameter of less than 1.0 m are generated in liquid by causing film boiling in liquid by means of a heater.

In a method for infusing a gas from a gas source into a liquid beverage, liquid beverage is driven from a beverage container into a liquid inlet port of a venturi mixing device. Nitrogen is infused into the liquid beverage by driving nitrogen through a gas inlet port of the venturi mixing device, thereby delivering nitrogen-infused liquid beverage to a discharge port of the venturi mixing device. The nitrogen-infused liquid beverage is poured from the discharge port through a faucet.

A bag assembly for use with a heat exchanger includes a flexible bag having of one or more sheets of polymeric material, the bag having a first end that bounds a first compartment and an opposing second end that bounds a second compartment, a support structure being disposed between the first compartment and the second compartment so that the first compartment is separated and isolated from the second compartment. A first inlet port, a first outlet port, and a first drain port are coupled with the flexible bag so as to communicate with the first compartment. A second inlet port, a second outlet port, and a second drain port are coupled with the flexible bag so as to communicate with the second compartment.

A nitrogen-enriched water generator includes an elongated housing defining a sealed nitrogen/oxygen chamber in which nitrogen molecules are combined with oxygen molecules to form a nitrate (NO.sub.3) or a nitrite (NO.sub.2) gas (NOx gas). The housing includes an NOx gas and water mixing tube, a plasma generator and a nitrogen-enriched water trap. A water spray nozzle sprays water into the chamber. At least one air injection port injects air into the chamber. A vacuum port removes a volume of NOx gas not absorbed by the water from the sealed nitrogen/oxygen chamber.
