The invention relates to a liquid
fermentation culture medium online degassing apparatus, which comprises a tank body, wherein the tank body is provided with a material inlet and a material outlet, a
liquid level sensor is arranged on the middle portion of the inner wall of the tank body, a
spiral flow guiding plate is arranged along the inner wall of the tank body, the
liquid level sensor is connected to an
electromagnetic valve arranged on the material inlet, the upper liquid
level line detecting position of the
liquid level sensor is on the middle-upper portion of the flow guiding plate, the lower liquid
level line detecting position is on the end of the flow guiding plate, the material inlet is connected to a variable
diameter flow guiding
pipe having a
diameter of larger than a material liquid port, the material liquid flowing out of the variable
diameter flow guiding
pipe flows along the flow guiding plate, and the top portion of the tank body is provided with a gas
discharge port for discharging the gas in the tank body, and a pressure gauge. According to the present invention, with the liquid
fermentation culture medium online degassing apparatus, the liquid
fermentation culture medium can be degassed before entering the liquid filter, such that the normal
filtration of the material liquid filter filtering core is ensured so as to substantially improve the
filtration efficiency and the
filtration flux of the filtering core.
