Problems solved by technology

[0003] When most of the existing liquid sterilization filters are used for sterilization and filtration, they mainly take over the material and filter directly without considering the nature of the filter element and the risk of bacterial contamination. For example, the filter element is hydrophilic and cannot be sterilized by air. The filter has a high filtration efficiency in the early stage of use, and the upper part of the filter element may not be soaked in liquid, and there may be bacteria-carrying air passing through the filter element, resulting in the risk of bacterial contamination

Abstract

The invention discloses design of a liquid filtering device and an online sterilization and degerming method. The liquid filtering device comprises a material supplementing tank, a liquid coarse filter, a liquid degerming filter and a reaction tank; a first stirrer is arranged at the central axis of the top end of the inner wall of the material supplementing tank, and a V4 pressure gauge is arranged on one side, far away from a hand hole, of the top of the material supplementing tank. The air sterilization filter, the material supplementing tank, the liquid coarse filter, the liquid sterilization filter and the reaction tank are connected through pipelines and valves, high-temperature steam sterilization can be independently carried out, safety and sanitation are achieved, bacterial pollution factors caused by the external environment are eliminated, then sterile air enters the material supplementing tank, and the positive pressure is increased; liquid raw materials or component raw materials in the material supplementing tank are pumped into the liquid coarse filter and the liquid degerming filter through pressure to be filtered and degermed and then enter the reaction tank, the situation that the first filter element is blocked due to the fact that the liquid raw materials or component raw materials are exposed in the external environment for a long time in pretreatment is avoided, and the safety, reliability and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of low-temperature liquid sterilization, in particular to a design of a liquid filter device and an online sterilization and sterilization method. Background technique [0002] The liquid sterilizing filter is composed of a filter element and a filter housing. The filter element is installed in the designated filter housing according to the operating procedures. The quantity is variable and depends on the specific production process. Finally, the filter housing sleeve is put on and fixed with clamps or bolts. . The filter element generally adopts a microfiltration filter element with a large specific surface area and a filtration accuracy of 0.22 μm or more, which can prevent impurities, harmful bacteria, and microorganisms in the culture solution from entering the culture container, production line, etc., thereby preventing product contamination. [0003] When most of the existing liquid sterilization filt...
