Description

Microbial fermentation equipment is with discharge valve that has defoaming function

Technical Field

Background

The strains used in the fermentation industry are mostly aerobic microorganisms, oxygen is consumed for growth, a large amount of sterile air needs to be introduced into the tank and stirred in the fermentation process to maintain the dissolved oxygen level in the fermentation liquor, and as the growth respiration of the microorganisms generates equivalent gas, fermentation culture media providing nutrition for the microorganisms and microbial metabolites usually contain a large amount of organic matters and proteins, foam is easily generated in the tank under the conditions of ventilation and stirring, once the foam is generated, the foam is difficult to eliminate by itself and continuously grows, the whole fermentation tank is finally filled with the foam, the foam touches the top of the fermentation tank and each interface and is even flushed out from an exhaust port, so that the liquid escape phenomenon is caused by taking away the fermentation liquor, somatic cells and the fermentation products, a large amount of foam seriously influences the normal production, such as blockage of an outlet pipeline and even scrapping of the fermentation liquor in the whole tank, measures need to be taken to eliminate the foam in the process operation, the foam phenomenon in biosurfactant production is more prominent because the presence of the surfactant stabilizes the foam and is more difficult to eliminate, which has limited the industrial scale production, and in order to avoid the liquid escape phenomenon and pollution problem caused by the foam, the technicians in the field initially take measures to reduce the charging coefficient, so that the upper part of the fermentation tank is allowed enough space to contain the growing foam, the foam is prevented from touching the top of the fermentation tank, and simultaneously, the aeration and stirring speed are reduced to reduce the generation of the foam. However, the reduction of the charging amount reduces the volume utilization rate of the fermentation tank, the reduction of the oxygen supply amount also greatly limits the growth rate of microbial cells, which obviously reduces the productivity of the fermentation tank, and the normal exhaust valve only can play a role of exhausting, so that the exhaust valve which can quickly and thoroughly defoam and simultaneously avoid the pollution of external bacteria is needed.
