A stirrer includes a stirring shaft; a plurality of mixing wings extending from the lower end of the stirring shaft and spaced from each other around the stirring shaft; and a conical hub connecting the lower ends of the mixing wings.

A beer line dispensing and cleaning system has a keg tapping head for connection to an outlet of a beer keg. A beer dispensing line is connected between the keg tapping head and a beer dispensing tap. An electrolytic ozone generator has a water inlet for connection to a water supply and an ozone water outlet for connection by an ozone water line to the beer dispensing line for delivery of ozone water through the beer dispensing line to sanitize the beer dispensing line.

An example of a beverage dispenser includes a nozzle and a valve coupled upstream of the nozzle. A sensor is operable to detect an object within a detection zone and provide a signal representative of a distance between the object and the sensor. A controller is configured to receive the signal from the sensor. The controller is configured to determine a sub-zone from a plurality of sub-zones within the detection zone in which the object is located. The valve is controlled between an open condition to dispense the substance through the nozzle and a closed condition based upon the determined sub-zone.

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.

An example beverage dispensing system includes a liquid circulation loop including a reservoir. The system also includes an inlet coupled to the liquid circulation loop to enable liquid to enter the liquid circulation loop, a thermoelectric cooling assembly configured to lower a temperature of liquid in the liquid circulation loop, a carbonation assembly configured to add carbonation to the liquid in the liquid circulation loop, a pump configured to circulate liquid through the liquid circulation loop, and an outlet coupled to the liquid circulation loop to enable liquid to exit the liquid circulation loop.

A beverage system that produces a beer includes a first source comprising uHGB, a second source including a carbonated and/or nitrogenated water, a first fluid line fluidly coupled to the first source and configured to allow the uHGB to flow from the first source through the first fluid line, a second fluid line fluidly coupled to the second source and configured to allow the water to flow from the second source through the second fluid line, a mixing point, that fluidly couples the first fluid line to the second fluid line, configured to allow the uHGB to blend with the water at the mixing point to produce the beer, first and second one-way valves on either side of the mixing point, and a third fluid line fluidly coupled to the mixing point and configured to allow the beer to flow to a dispensing tap.

Disclosed is a water dispenser. The water dispenser includes a water outlet component; a water cooling module for accessing a water source, an output port of the water cooling module being communicated with the water outlet component through a first water pump; and/or a water heating module, an input port of the water heating module accessing the water source through a second water pump, an output port of the water heating module being communicated with the water outlet component, the water outlet component accessing the water source through the second water pump.

A beverage supplying apparatus that supplies a beverage into a beverage container, includes: an ingredient storage unit to store a beverage ingredient; a compressed gas supplying means to supply compressed gas to the ingredient storage unit and pressurize the beverage ingredient; and a beverage supplying means to, when receiving a supply command, allow the pressurized beverage ingredient to be supplied to a nozzle, and supply compressed nitrogen gas to the nozzle, so that the nitrogen gas and the beverage ingredient are mixed and stirred at the nozzle and the beverage is discharged to the beverage container through the nozzle.

A refrigerator appliance includes a cabinet with a food storage chamber defined in the cabinet. The refrigerator appliance also includes a door rotatably mounted to the cabinet. The door includes an outer surface and an opposing inner surface, wherein the inner surface faces towards the food storage chamber when the door is in the closed position and the outer surface faces away from the food storage chamber when the door is in the closed position. The refrigerator appliance also includes a dispenser assembly with a plurality of liquid sources fluidly coupled to the dispenser assembly and a multi-fluid tube. Each liquid source of the plurality of liquid sources is fluidly coupled to the dispenser assembly through the multi-fluid tube.

Devices, systems, and solutions for cleaning tap lines are described herein. One tap line cleaning system, includes a beverage dispensing tap, a beverage storage container, a tap line allowing fluid communication of a beverage between the beverage storage container connected at a first end of the tap line and the beverage dispensing tap connected at a second end of the tap line, a cleaning solution reservoir, a cleaning solution line allowing fluid communication of a cleaning solution into the first end of the tap line such that the cleaning solution can pass into the first end of the tap line, out of the second end of the tap line and exit the system via the beverage dispensing tap, and a valve to switch a valve position between closed and open to allow fluid communication of the cleaning solution to the tap line.
