Microbial culture concentrated filtration system

The present invention relates to a microbial culture concentrated filtration system, in particular to a microbial culture concentrated filtration system capable of concentrating a microbial culture solution or producing a microbial-free filtration solution.

Microbial fermentation includes liquid fermentation and solid fermentation. The fermentation quality of liquid fermentation is relatively stable, and the fermentation speed is fast. It can be mass produced in a short time. Generally, it can be divided into "primary culture method" and "batch feed culture. The method and the "continuous culture method", wherein the primary culture method is a conventional culture method in which all the raw materials and microorganisms are added to the culture tank until the culture is completed, and then the contents are completely taken out;

The "batch fed culture method" refers to a method of intermittently or continuously replenishing fresh culture materials in batches at different growth stages of microorganisms. The raw materials to be supplemented may be all materials, or may be nitrogen sources, carbon sources, etc., in order to prolong the synthesis time of metabolites to achieve greater mass production or control the quality of specific products, and the like;

The "continuous culture method" refers to a fermentation method in which a new culture solution is added to a fermenter while the original culture solution is also recovered. The advantages are high equipment utilization, stable product quality, easy automatic control, etc. The disadvantage is that it is easy to contaminate the bacteria. It is usually only suitable for strong microorganisms that have great adaptability to the environment, such as acetic acid bacteria.

As a result, as shown in FIG. 4C, when the filtration is stopped, the positive pressure type micropore filter 154 is internally a concentrate 15421 having a microorganism, and then the concentration relay unit 13 and the concentrate 15111 having the microorganisms in the positive pressure microporous filter 154 are taken out by the liquid take-out unit 19, and collected and stored in the collection unit. 20;

Alternatively, the concentrate having the microorganisms is not returned to the concentration relay unit 13, but according to the limit that the concentrated filter unit 15 can bear and the minimum point limit of the liquid inside the concentration relay unit 13, The raw liquid of the microorganism is continuously transported to the concentrated filter unit 15 to discharge the liquid 15422 having no microorganisms, and after the limit that the concentrated filter unit 15 can bear, the filtering operation is not performed, and when the filtration is stopped, the liquid is also stopped. The microbial concentrate 15421 is retained inside the positive pressure microporous filter 154, and then the concentrated relay unit 13 and the positive pressure microporous filter 154 have microorganisms in the positive pressure microporous filter 154. The concentrate 15111 is taken out and collected and stored in the collection unit 20.

Further, in addition to being used to concentrate microorganisms, the present invention has an effect of discharging a liquid having no microorganisms, and therefore, if a liquid having no microorganisms is to be obtained, it can be achieved by the system.
