Abstract
A beer frothing device for stably generating froth without degrading beer quality is provided. The device frothing beer in a vessel by squirting a pressurized gas through a nozzle submerged in the beer, includes a pressurized gas supply, a squirting mechanism, connected to the gas supply and having a cutoff valve to obstruct the gas squirting through the nozzle, a lifting mechanism for supporting the squirting mechanism during its vertically reciprocating up-and-down movement with a half track between a start point where the nozzle is positioned right above the vessel and a lower point where the nozzle is submerged at a predetermined depth in the beer, a start switch for lowering the lifting mechanism, a direction change switch for raising the lifting mechanism when the lower point is detected during lowering operation, a stop switch for stopping the lifting mechanism when the start point is detected during rising operation, and an open-valve switch, arranged between the direction change switch and the stop switch, for opening the cutoff valve to detect an appropriate position where the nozzle is submerged in the beer. The direction change switch and the stop switch make a limit switch.
