Microbial expanding culture system

Abstract

A microbial expanding culture comprises a culture and fermentation tank, an oil-free mute air pump, a material hot water circulating pump and a hot water tank, a heating pipe coil and an aeration distributor are arranged in the culture and fermentation tank, the oil-free mute air pump is connected with the aeration distributor through a pipeline, the hot water tank, the material hot water circulating pump and the heating pipe coil are connected through a pipeline to form a closed loop, the pipeline between the hot water tank and the material hot water circulating pump is provided with a culture tank water supplementing butterfly valve, the pipeline between the heating pipe coil and the material hot water circulating pump is provided with a hot water circulating butterfly valve, a branch pipeline is arranged between the hot water tank and the material hot water circulating pump, the branch pipeline is provided with a discharging control butterfly valve, the material hot water circulating pump is connected with a discharging pipeline, and the discharging pipeline is provided with a discharging butterfly valve. The microbial expanding culture system has the advantages of simple structure, realization of intelligent control of the temperature and the aeration on-off, less energy consumption, and meeting of energy saving and miniaturization demands due to multiple uses of one circulating pump used for providing hot water circulation and meeting material discharge.

Description

technical field [0001] The invention belongs to the field of microorganism cultivation, and more specifically relates to a microorganism expansion cultivation system. Background technique [0002] The fermentation culture of the bacterial liquid requires ventilation and song song to ensure the oxygen demand, refrigeration, ventilation and song song to meet the temperature demand, and water to ensure the water demand, so the demand for fermentation equipment is high; and the general fermentation equipment is large in size and inconvenient to move. The convenient and energy-saving production of bacteria cannot be satisfied; in addition, the control of water, gas and temperature of fermentation equipment is generally controlled manually, which requires a large amount of labor and cumbersome operation. Contents of the invention [0003] The object of the present invention is to provide a microbial expansion cultivation system to solve the deficiencies of the prior art, which h...
