Abstract

---- The invention discloses an aerobic fermentation tank, which mainly includes a fermentation tank body, a feed inlet, an air inlet, a material outlet and an exhaust outlet. A motor is arranged in the middle of the top of the fermentation tank body, and the motor is connected to a transmission rod. The transmission rod is connected to the rotatable air main pipe installed inside the fermentation tank. Several rotatable air branch pipes are evenly distributed on the rotatable air main pipe. Several air holes are evenly distributed on the rotatable air branch pipes. The air inlet is set through the fermentation tank body. The internal sterilizer is connected to the fixed air main. The beneficial effects of the present invention are as follows: through the rotation of the rotatable air main pipe and the rotatable air branch pipe, it plays the role of introducing air and stirring at the same time, reducing energy consumption, distributing air through air distribution holes, and improving the efficiency of dissolved oxygen; There is a sterilizer to remove germs in the gas; heat is provided by an electric heater to make the microorganisms reach a temperature suitable for metabolism.

Description

technical field [0001] The invention relates to a fermenter, in particular to an aerobic fermenter, which belongs to the field of biological equipment. Background technique [0002] Aerobic fermenter is the key equipment for the production of antibiotics, glutamic acid, citric acid, yeast and other fermentation industries. Since the oxygen needed for the respiration of aerobic microorganisms and the oxidation of the substrate is dissolved oxygen in the liquid phase, the gas-liquid mass transfer of oxygen is very important in the aerobic fermentation process, and air needs to be continuously introduced into the fermentation liquid during the fermentation process. for the oxygen consumed by microorganisms. The oxygen uptake of the microbial group is very large, usually 10-50×103mol / (L h), but the solubility of oxygen in the fermentation broth is very low. The saturation solubility in the medium is only 0.2×103mol / L, and insufficient dissolved oxygen will seriously affect the...
