Abstract

This utility model discloses a beer fermentation external circulation timed stirring device, relating to the field of beer processing technology. It includes: a fermentation tank with a stirring component in the middle; a liquid outlet pipe fixed to the bottom of the fermentation tank; a liquid discharge component disposed inside the liquid outlet pipe and at the bottom of the stirring component; a first connecting pipe fixedly installed at one end of the liquid outlet pipe, and a three-way valve fixedly installed at one end of the first connecting pipe; a second connecting pipe fixedly installed at the top of the three-way valve, and a discharge pipe fixedly installed at the bottom of the three-way valve; and a disturbance component installed at the top of the second connecting pipe. This utility model automatically discharges the fermentation liquid from the bottom of the fermentation tank without requiring an additional power source, reducing energy consumption, creating a circulating stirring effect, and ensuring that the liquid re-entering the fermentation tank is fully mixed with the internal fermentation liquid, avoiding uneven local concentrations, promoting uniform fermentation, and achieving automated timed control.
