Solar microbial fermentation device

Abstract

The invention discloses a solar microbial fermentation device. A hollow stirring device with holes is arranged, an air inlet pipe and a water inlet pipe are communicated with the stirring device so that during a stirring process of the device, even oxygenation can be carried out, the stability of oxygen content during a fermentation process is effectively kept, meanwhile, the air inlet pipe and the water inlet pipe are connected with a solar heat collecting device through an electric heater, temperature is adjusted in the process of oxygenation, water can be sprayed out from the holes of the stirring device to form high-pressure water columns, and the inner portion of a fermentation tank is washed and disinfected by rotating of blades. In addition, a lower supporting plate with a double-layer structure is arranged so that the collecting efficiency of fermentation liquor can be effectively improved, and the fermentation liquor can be filtered preliminarily. The solar microbial fermentation device has the advantages of being even and stable in oxygen content, fermentation temperature can be easily controlled, and washing and disinfecting are convenient.

Description

technical field

[0001] The invention relates to the fields of solar energy utilization and fermentation equipment, in particular to a solar microbial fermentation device. Background technique

[0002] A fermenter is a commonly used device for the cultivation of microorganisms or cells, either for research, analysis or production. Different microorganisms require different fermentation conditions. For example, the fermentation of aerobic microorganisms requires a certain amount of oxygen in the fermenter, and the amount of oxygen and its stability directly affect the fermentation time and fermentation products of microorganisms. Therefore, the current methods for aerobic microorganisms Fermentation tanks often use stirring to add oxygen. There are generally two stirring methods. One is to install a motor on the top of the tank. The main shaft of the agitator goes deep into the tube from the top of the tank. Poor performance, less exposure to air at the bottom of the fermenta...
