A beverage dispenser includes a gas infusion device that receives a base fluid and a gas and dispenses a gas infused liquid, a ratio pump that receives the gas infused liquid and a concentrate from a concentrate source and dispenses a predetermined ratio of the gas infused liquid and the concentrate, and a mixing chamber that mixes the predetermined ratio of the gas infused liquid and the concentrate to form a reconstituted beverage. An insulated enclosure has an interior space in which the ratio pump and the mixing chamber are positioned. A cooling heat exchanger is positioned in the insulated enclosure, and a first refrigeration system circulates a cooling media through the cooling heat exchanger to thereby cool the interior space to a suitable temperature such that the gas infused liquid and the concentrate dispensed from the ratio pump and the mixing chamber are cooled to the suitable temperature.

A beverage dispenser is for dispensing a consumable beverage. A processing line having a fluid path with an input end is fluidly connectable to a source container of liquid for receiving liquid from the container via a driving force, and for processing the liquid into the consumable beverage to be dispensed. A Venturi injector is provided along a fluid segment of the fluid path of the processing line, the Venturi injector being configured for selectively and adjustably injecting gas bubbles into the consumable beverage to alter at least one resulting parameter of the consumable beverage to be dispensed. The beverage dispenser also includes a tap fluidly connectable to an output end of the fluid path of the processing line for receiving the consumable beverage with at least one resulting parameter having been altered, and for selectively dispensing the consumable beverage via an activation of the tap.

A beverage dispenser includes a gas infusion device configured to infuse a gas into a base liquid to form a gas-infused liquid, a mixing chamber configured to mix the gas-infused liquid and a concentrate to thereby form a reconstituted beverage, a first flow control configured to decrease pressure of the gas-infused liquid prior to mixing with the concentrate, and a second flow control configured to decrease pressure of the concentrate prior to mixing with the gas-infused liquid. A restrictor device downstream from the mixing chamber and configured to apply backpressure on the concentrate and the gas-infused liquid, and a dispensing valve is configured to dispense the reconstituted beverage.

Beverage dispensing system (10) comprising: —one or more pressure chambers comprising a connectable base (14) part and lid (12) defining a sealed inner space (16) for accommodating and encapsulating a —40 collapsible beverage container (18) having a beverage outlet connectable to the base part (14), —a tapping device (34) comprising one or more tapping heads (36) for extracting the beverage from the collapsible beverage to container(s), —a tapping line (28) extending from said base part (14) to said tapping device, said tapping line comprising one or more beverage lines, and —at least one measuring device (56) configured for monitoring at least one physical quantity of the tapping line, sealed inner space, base part, lid and/or collapsible beverage container, said measuring device configured to have a sampling rate of at least 10 Hz, wherein the beverage dispensing system is configured for —processing data from the measuring device, and —detecting an event in the system by continuously analysing data from the measuring device.

A liquid sales management device is to be added to a liquid supply system supplying a liquid within a storage container to a dispensing device through a supply pipe with the liquid pressurized in order to cool the liquid in the dispensing device, and dispensing the cooled liquid to a drinking container. The liquid sales management device includes an actual flow rate determining unit that determines an actual measured flow rate of the liquid dispensed into the drinking container from the dispensing device, a cleaning mode detection unit that detects a cleaning mode in the liquid supply system, and a consumption flow rate acquisition unit that determines an actual consumption of the liquid based on the number of cycles of the cleaning mode, a known liquid amount consumed in one cycle of the cleaning mode in the liquid supply system, and the actual measured flow rate.

Provided is a water purifier. The water purifier includes an agitator configured to agitate cooling water and heat-exchange the cooling water with a cooling coil, a motor coupled to the agitator to allow the agitator to rotate, the agitator operating at at least two rotational speeds other than zero, and a control assembly configured to control the rotational speed of the motor.

Cooler control system for a beverage dispense system 1 having a beverage line (2) extending from a beverage source to a dispense site via a cooler (6). The cooler control system comprises: a controller (51) for adjusting the cooling of the beverage line; a flow rate sensor (41) measuring the flow rate in the beverage line, a temperature sensor (40); and an electronic control unit (31) for receiving a signal from the temperature sensor and/or the flow rate sensor and sending a signal to said controller. Cooler monitoring system comprising: at least one sensor (45) for monitoring energy consumption of the cooler (6); and an electronic control unit for receiving a signal from the at least one energy consumption sensor and for sending a signal to a remote location when energy consumption increases above a predetermined maximum value.

A roving beverage dispensing device has a beverage container in a cooled compartment and a flexible beverage dispensing line with connecting means coupling its inlet end to the container. A pressure line is releasably connected to the container and to a source of pressurized gas. An elongated tapping column fixed to the top of the compartment comprises elongated inner channel bringing in communication the interior of the compartment with tapping valve element suitable for receiving a portion of the outlet end of the dispensing line and for controlling the flow of liquid therethrough. The largest diameters of the dispensing line and the connecting means are sufficiently small so that the dispensing line can be introduced from the top end of the tapping column through the elongated channel into the compartment and connected to the container.

A cooling device is provided for cooling a beverage in a dispensing line. The device comprises two heat exchangers for exchanging thermal energy between the beverage and a coolant fluid in a cooling circuit; the coolant fluid having a lower temperature than the beverage. Placing the two heat exchangers in series relative to the dispensing line, provides two-stage cooling, allowing more accurate cooling. This may be improved by placing brute force cooling to a particular temperature window, followed by accurate cooling. This makes the cooling process is less sensitive to whatever the initial temperature of the beverage may be. Relative to the cooling circuit for the coolant, the two heat exchangers may be placed in parallel and, optionally, further in parallel to a buffer circuit. A distribution module may be provided to control distribution of coolant over the heat exchangers, optionally from the buffer, to control temperature of the beverage.
