Fermentation tank overflow collecting, separating and recycling device

Abstract

The invention relates to a microbial fermentation device, in particular to a fermentation tank overflow collecting, separating and recycling device which comprises a fermentation tank and an exhaust pipe on the fermentation tank. The device is structurally characterized in that the device comprises a vapor-liquid cyclone separator and a centrifugal separator, the vapor-liquid cyclone separator is connected between the exhaust pipe and an exhaust pipe outside the tank, a liquid collecting pipe is connected on the lower portion of the vapor-liquid cyclone separator, the centrifugal separator is arranged in the liquid collecting pipe, and a motor drives the centrifugal separator to rotate. By the aid of primary separation of the cyclone separator and secondary separation of the centrifugal separator, separation, collection and backflow fermentation broth overflowed and foam carried by the fermentation broth can be timely and simultaneously achieved, so that the fermentation broth is cultured and propagated under good process condition, and yield and quality of microbial varieties are ensured.

Description

Technical field [0001] The invention relates to a microbial fermentation device, in particular to a fermentation tank overflow collection, separation and recovery device. Background technique [0002] In the entire process of fermentation and reproduction of microorganisms in the proposed fermentation equipment, the absorption and transformation of raw materials and auxiliary materials will release a certain amount of energy under specific process conditions, which affects the reproduction and growth of bacteria. The main manifestations are: fermentation With the increase of liquid material, when the amount of liquid material exceeds the tank capacity, the phenomenon of full tank drainage will occur, which is termed "jumping". Liquid skipping affects the product quality and output of the tank, and it pollutes the environment during the liquid skipping process. Similarly, microorganisms will produce foam in many varieties during the process of reproduction and fermentation. Repe...

AI Technical Summary

Problems solved by technology

Repeated generation of foam will also exceed the capacity of the tank and cause liquid jumping, which will affect the output and quality and pollute the environment
