Enzyme preparation is a product that extracts this protein from biological tissues and refines it. It is mainly divided into amylase, lipase, protease and cellulase, etc. Because the temperature, PH value, oxygen and nutrients in the fermentation process are very important for the production of high quality enzyme preparations, it is necessary to install a filtration system to remove pollutants from the enzyme preparation during the production process. Let us take a look at which filtration processes are used in the production process of enzyme preparations.


1. Fermentation Additive Filtration Process

Fermentation additives mainly include water, liquid nutrients and pH regulators, etc. The filtration system is mainly to trap microorganisms, bacteria and other pollutants that may pollute the additives. Ensure that the enzyme preparation is not contaminated during the fermentation process. The equipment of the fermentation additive filtration system generally chooses Sanitary SUS316L Filter Housings, and the filtration consumables usually use Hydrophilic PVDF Membrane Pleated Filters with 0.2 micron.

2. Fermentation Air/Gas Filtration Process

The fermentation air/gas filtration system is mainly installed on the fermentation tank and the liquid storage tank. Its function is to trap the air/gas pollutants such as fine particles, bacteria, microorganisms and phages, and ensure that the fermentation broth of enzyme preparations in the tank is fermented under aseptic conditions. The equipment of the filtration system generally chooses Sanitary SUS316L Vent Filter Housings, and the filtration consumables usually use Hydrophobic PTFE Membrane Pleated Filters of 0.2 micron.

3. Sterilization Filtration Process

The sterilization filtration process is generally used in the upstream of the enzyme preparation filling process. As the last protective barrier of enzyme preparation, it ensures that there are no contaminants such as bacteria and microorganisms in the enzyme preparation, and improves product quality. The equipment of the filtration system generally chooses Sanitary SUS316L Filter Housings, and the filtration consumables usually use Hydrophilic PVDF Membrane Pleated Filters of 0.2 micron and 2 layers of PVDF membrane filter media.

Enzyme preparations are now widely used in the fields of food and beverage, textiles, medicine and papermaking. Because the types of enzyme preparations used in different fields may be different, when designing the filtration system, the appropriate filter housing and filter element should be selected according to the types of nutrients and PH adjustment fluids.
