A defoaming system for a fermenter and a fermenter

Abstract

The utility model belongs to the field of biological fermentation technology discloses a defoaming system for fermentation tank and fermentation tank, and the fermentation tank includes jar body, sprays subassembly, liquid supply subassembly, liquid level detection unit and control unit. Sprays subassembly includes liquid injection pipe and a plurality of atomization spray pieces. The liquid injection pipe is arranged in the jar body and located at the top. A plurality of atomization spray pieces are arranged on the liquid injection pipe at intervals and detachably connected with the liquid injection pipe. The liquid supply subassembly includes a first liquid storage container for storing defoaming agent and a liquid supply pipeline. One end of the liquid supply pipeline is in communication with the inner cavity of the first liquid storage container, and the other end is in communication with the liquid injection pipe. The liquid level detection unit is arranged in the jar body. The control unit is in communication connection with the liquid level detection unit. The control unit is arranged on the liquid supply pipeline and used for controlling the liquid supply pipeline to deliver the defoaming agent to the liquid injection pipe. The fermentation biological surfactant using the fermentation tank can make the defoaming agent fully contact with the foam, effectively eliminate the foam, and reduce the dosage of the defoaming agent.
