Description

Technical Field

[0001] The utility model relates to the technical field of enzyme processing, in particular to a liquid enzyme raw material filtering device. Background Art

[0002] Biological enzymes are organic substances with catalytic effects produced by living cells. Most of them are proteins, and a very small part is RNA.

[0003] The preparation of enzymes can be divided into solid fermentation and liquid fermentation. After the production raw materials are inoculated with microorganisms for fermentation, the solid fermentation method requires the solid raw materials to be crushed to obtain a solid preparation or soaked in water and filtered to obtain a liquid preparation. The liquid fermentation method directly filters after fermentation, concentrates and then dries to obtain an enzyme preparation. The above methods all involve the filtration and separation of the enzyme liquid raw materials. When filtering the existing enzyme liquid raw materials, because the filter residue is relatively fine and crushed, the filtrate will also have different viscosities due to specific production practices. Therefore, the original filtration efficiency of the enzyme liquid is often low, and the filtration effect is poor, and the filtrate is easily mixed with the raw material filter residue.

[0004] Therefore, the enzyme preparation raw material filtering device proposed in the patent with publication number CN208362311U improves the filtering effect by filtering multiple times, but also prolongs the filtering process and increases the filtering time.

[0005] There is also a raw material dissolving and filtering device for extracting biological cellulase, such as the patent with publication number CN217068060U, which pressurizes the interior of the filter bin through the air outlet pipe, and the dissolving bin and the filter bin as a whole should be a sealed environment. With the continuous pressurization of the air outlet pipe, the filtrate is quickly filtered through the ultrafiltration plate. The practicality of the pressurizing mechanism is high, which indirectly improves the extraction rate of cellulase and brings better use prospects. The device speeds up the filtration speed by pressurized filtration, but the device pressurizes by air pressure, which has high requirements for the sealing of the device, and is not suitable for multi-stage filtration, but only for relatively simple liquid raw material filtration. Utility Model Content

The downward pressure of the filter press plate and the downward pressure of the filter press chamber make the filtrate in the third chamber enter the fourth chamber for secondary filtration. At the same time, the downward pressure of the filter press chamber makes the filtrate in the fourth chamber flow into the second chamber for tertiary filtration.

[0019] The utility model can simultaneously coordinate the downward pressure of the filter press plate with the downward pressure of the filter press bin as a whole, so that there is enough pressure for filtration in each filtration process, and the efficiency and effect of filtration are fully guaranteed.
