Liquid fermentation culture medium online degassing apparatus

Abstract

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.

Description

technical field [0001] The invention relates to a degassing device, in particular to an online degassing device for a liquid fermentation medium. Background technique [0002] In the prior art, the aseptic filtration of soluble fermentation medium usually adopts membrane filtration technology; membrane filtration technology is applied to prepare aseptic fermentation medium on the aseptic filtration of soluble fermentation medium, instead of traditional steam elimination, It has the advantages of energy saving, light color of prepared culture medium and the like. The specific operation is that the prepared fermentation medium enters the sterile liquid filter through the pipeline, and enters the pre-sterilized fermenter after being filtered by the filter. However, in this technology, when the liquid medium is transported under pressure, air bubbles will be generated during the pipeline transport process due to the pressure drop of the pipeline. After these bubbles enter the l...

Problems solved by technology

However, in this technology, when the liquid medium is transported under pressure, air bubbles will be generated during the pipeline transport process due to the pressure drop of the pipeline. After these bubbles enter the liquid filter, they will affect the normal filtration of the liquid filter element, and the flux of the filter element will be greatly reduced. , resulting in a decrease in the filtration efficiency of the liquid filter
