System for dispensing a beverage into a container (18) comprising at least one dispenser unit (10). The dispenser unit (10) comprises at least one beverage outlet port and a movable seal member (34) which is configured to form a sealing barrier between at least a portion of the container (18) and the dispenser head. In this way the container is pressurised before filling, so as to avoid excessive foaming.

A water purifier includes a water tank having a cold water path inside the tank, a coolant inside the water tank, a cooling device including an evaporator inside the water tank and through which a refrigerant flows, and a compressor that is operable to compress the refrigerant. The cooling device is configured to cool the coolant to cool water flowing through a temperature sensor, which is configured to detect a temperature of the coolant and output coolant temperature information about the detected temperature of the coolant. The purifier also includes an agitator operable to agitate the coolant and a controller configured to control the compressor and the agitator to operate simultaneously and control the agitator to stop operating while the compressor is controlled to continue operating based on preset ice-making temperature information and the coolant temperature information. There is also a method of controlling a compressor and an agitator.

A method for cooling a mixed beverage formed with one or more beverage components includes circulating a refrigerant through a heat exchanger having a phase change material to cool a beverage component and sensing a temperature of the refrigerant. The method further includes detecting a first instance when the sensed temperature of the refrigerant equals a threshold refrigerant temperature, detecting a second instance when the sensed temperature of the refrigerant equals the threshold refrigerant temperature, and stopping circulation of the refrigerant when the second instance is detected.

Provided is a cooling tank comprising a tank body in which a water accommodation space is formed, a foaming case for encompassing the outer peripheral surface of the tank body, and a foam insulating material formed by a foaming agent flowing into the foaming space between the outer peripheral surface of the tank body and the foaming case, and then foaming, wherein the foam insulating material is integrated with the tank body and the case through foaming, and the case has an air outlet through which air of the foaming space is discharged during a foaming process.

A drink station is provided with an alkaline filter cartridge in fluid communication with an ambient temperature water line provide alkaline water, and with a chilled water mixed with the alkaline water at a spigot to provide chilled alkaline water. A hot water heating element is located below the spigot so hot water flows upward for dispensing from the spigot, with a vent line between the heating element and spigot helping hot water to flow from the spigot to the heating element. A refrigeration system and a carbonation system is also provided. The refrigeration system uses the ice-bank technology. A submersible agitator pump improves heat exchanged between ice-bank and water by forced convection. The agitator pump operating based on the temperature of the drinking water. A figure eight evaporator coil can provide two cylindrical ice banks and two chilled water coils to increase the chilled water capacity.

A liquid quality management device capable of being added to a liquid supply system supplying a liquid in a storage container to a dispensing device in order to cool the liquid and dispensing the liquid into a drinking container includes: a dispensing sensor; and a control device electrically connected to the dispensing sensor and configured to perform control operation of at least one of a refrigeration machine and a stirring device provided in the dispensing device at the same time when dispensing of the liquid is started.

A beverage dispensing machine for dispensing a mixed beverage has a first inlet configured to receive a concentrate; a second inlet configured to receive a base fluid; a gas inlet configured to receive a gas; a gas injection device configured to pulsate the gas into the concentrate such that the gas agitates the concentrate and is injected into the concentrate to form a gas-injected concentrate; and a dispensing valve configured to dispense the base fluid and the gas-injected concentrate.

An ice bath comprising a container, a refrigeration coil for causing liquid in the container to turn to ice, a pipe for carrying liquid to be cooled by the ice bath for dispense and a plurality of conductive probes for measuring ice thickness, wherein the conductive probes are provided between at least part of the refrigeration coil and the pipe for carrying liquid to be dispensed such that a first one of the conductive probes is provided closer to the refrigeration coil at least two other conductive probes, and thereby the at least two other conductive probes are provided closer to the piping than the first conductive probe, and wherein the second and third probes are equidistant from the refrigeration coil, the ice bath further comprising means for measuring the conductance between the first probe and the second probe, the first probe and the third probe, and the second probe and the third probe.
