The present invention discloses a beer spear with a pressure relief valve, which comprises a beer spear seat, a pressure relief valve, an inner tube fixing sleeve, an inner tube fixing spring and an inner tube assembly; the pressure relief valve is arranged on the outer side of the beer spear seat and the pressure inlet of the pressure relief valve communicates with a gas storage chamber; a head movable hole matching the head of a dispenser is opened at the top of the beer spear seat. The present invention is more convenient to assemble and disassemble a draft beer keg, and also the space for the draft beer keg is saved and the problems such as gas leakage and draft beer spoiling caused by damages of the gas tube are avoided.

The present invention is directed to a beverage dispensing system including at least one beverage dispensing container, a computing device and a base unit upon or within which, in use, the at least one container is positioned. The at least one container includes a reservoir of beverage, a communication element for storing data indicative of contents of the beverage dispensing container, a manually actuatable dispensing valve selectively controlling flow of beverage from the reservoir to a container outlet, and pressurizing means for pressurizing beverage against the dispensing valve such that when the dispensing valve is opened beverage flows from the reservoir and out the container outlet. The base unit includes at least one base-container transceiver for wirelessly reading data from and writing data to the communication element, at least one base-device transceiver for wirelessly communicating with the computing device, and a control unit controlling communication of data from the computing device to the communication element and vice-versa.

An integrated alcoholic beverage fresh-keeping barrel system, comprising a housing, and an inner container, wherein the inner container is divided into two layers, and comprises a gas storage tank located at the upper layer for storing gas and an alcoholic beverage barrel located at the lower layer for storing a liquid beverage; the gas storage tank and the alcoholic beverage barrel are coaxially arranged one above the other; a gas channel that can be opened and closed is provided between the gas storage tank and the alcoholic beverage barrel; the alcoholic beverage barrel is provided with a liquid outlet end and an outflow liquid channel for opening and closing the liquid outlet end; a control system is provided above the gas storage tank; the control system controls the opening and closing of the gas channel, and performs linkage control on the opening and closing of the outflow liquid channel.

Embodiments of the present disclosure are directed to extracting the liquid from a container (such as a bottle of wine) in varying amounts at a desired serving temperature while preserving the liquid for later consumption. Various embodiments may be built within an appliance so the consumer experience is fully automated. Embodiments may include a variety of wine preservation techniques including the use of inert gases that prevent the oxidation of wine.

A liquid dispenser comprise a nozzle comprising an inlet in fluid communication with an outlet to form a flow path, a thermistor in fluid communication with the inlet, an actuator rod comprising a gasket rod tip viton, at least one centering pin to center the actuator rod in at least a portion of the flow path, a flowmeter in fluid communication with the inlet, a double acting pneumatic cylinder comprising a first pneumatic inlet and a second pneumatic inlet operatively connected to the actuator rod, and a switch lever operatively coupled to a micro switch, wherein the nozzle opens when gas enters the first pneumatic inlet when the switch lever is activated by pressing on the micro switch and closes when gas enters the second pneumatic inlet when the switch lever is deactivated. Portable and non-portable liquid dispensing systems comprising the liquid dispenser are also described.

Apparatus, for making an individual drink, with a pressure source, a store defining a plurality of housings, a plurality of removable containers each immobilized, in a service position, in a respective housing. Each container including a receptacle containing an ingredient, and an upstream emptying valve allowing the ingredient to leave towards the outside via an overpressure generated inside the receptacle by the pressure source. A chamber receives the ingredients extracted from the containers, via the upstream emptying valves, under the effect of the overpressure, so as to make the drink. A control module commands the overpressures in the containers as a function of a desired composition for the drink. Each housing includes a draining coupling via which the ingredient of the container immobilized in the housing can be extracted from the container. The draining coupling opening, in the downstream direction, directly into a funnel defined by the chamber.

A liquid dispenser comprise a nozzle comprising an inlet in fluid communication with an outlet to form a flow path, a thermistor in fluid communication with the inlet, an actuator rod comprising a gasket rod tip viton, at least one centering pin to center the actuator rod in at least a portion of the flow path, a flowmeter in fluid communication with the inlet, a double acting pneumatic cylinder comprising a first pneumatic inlet and a second pneumatic inlet operatively connected to the actuator rod, and a switch lever operatively coupled to a micro switch, wherein the nozzle opens when gas enters the first pneumatic inlet when the switch lever is activated by pressing on the micro switch and closes when gas enters the second pneumatic inlet when the switch lever is deactivated. Portable and non-portable liquid dispensing systems comprising the liquid dispenser are also described.

An integrated alcoholic beverage fresh-keeping barrel system, comprising a housing, and an inner container, wherein the inner container is divided into two layers, and comprises a gas storage tank located at the upper layer for storing gas and an alcoholic beverage barrel located at the lower layer for storing a liquid beverage; the gas storage tank and the alcoholic beverage barrel are coaxially arranged one above the other; a gas channel that can be opened and closed is provided between the gas storage tank and the alcoholic beverage barrel; the alcoholic beverage barrel is provided with a liquid outlet end and an outflow liquid channel for opening and closing the liquid outlet end; a control system is provided above the gas storage tank; the control system controls the opening and closing of the gas channel, and performs linkage control on the opening and closing of the outflow liquid channel.

A pressure control device for controlling a pressure in a beverage container comprises a gas filled pressure control chamber enclosed by a wall of the pressure control device. The wall has an inner surface facing the chamber and an outer surface facing away from the chamber, the inner surface and outer surface defining a thickness of the wall. A scavenger material is provided in the pressure control device for capturing gas that enters, during use, into the pressure control chamber. The scavenger material is distributed over the wall thickness with a predetermined concentration from the inner surface towards the outer surface of the wall such that a rate of gas capture by the scavenger material changes over time.
