Abstract

The invention relates to a bacterial culture fermentation tank device and a fermentation technology thereof. The bacterial culture fermentation tank device is characterized in that the top of the fermentation tank is provided with a cleaning and disinfecting charging tube, a feeding tube and an air input tube; the fermentation tank is controlled by a PLC controller, and the input end of the PLC controller is connected with a temperature sensor, a pH value sensor, a dissolved oxygen value sensor and a stirring speed sensor which are arranged in the tank body; the lower side of the fermentationtank body is provided with a dumping tube; the cleaning and disinfecting charging tube is communicated with a pure steam input tube, an input tube of water for injection, an acid-base lotion input tube, a purified water input tube and a drinking water input tube, wherein the bypass direction of the pure steam input tube is provided with the air intake tube of the air filter; and the air intake tube extends to the bottom of the fermentation tank. The device has good online cleaning, online sterilization and heat preservation effect and is favourable for culturing and fermenting bacteria.

Description

technical field [0001] The invention relates to a bacteria culture and fermentation device, in particular to a bacteria culture and fermentation tank device and a fermentation process thereof. Background technique [0002] Fermentation engineering consists of three parts: upstream engineering, midstream engineering and downstream engineering. Among them, the upstream project includes the selection of excellent seed strains, the determination of the optimum fermentation conditions (pH, temperature, dissolved oxygen and nutrient composition), the preparation of nutrients, etc. Midstream engineering mainly refers to the process technology of cultivating cells in large quantities and producing metabolites in fermentors under optimal fermentation conditions. There must be a strict aseptic growth environment here, including the technology of using high temperature and high pressure to sterilize the fermentation raw materials, fermentation tanks and various connecting pipes before...
