The filtration, separation, concentration and purification of biological enzyme preparations is a process involving multiple steps, which are crucial for enhancing the purity and activity of the enzyme preparations. 

Filtering function: The enzyme preparation filter machine is mainly used to remove impurities from the enzyme preparations, such as microorganisms, fragments, pigments, etc. These impurities can seriously affect the purity and activity of the enzyme preparations. 

Technology: Through the use of precise filter screens, the enzyme preparation filter machine can effectively remove these impurities, ensuring the purity and activity of the enzyme preparations. 

Separation principle: Enzyme separation and purification refers to the process of extracting enzymes from cells or other enzyme-containing materials, separating them from impurities, and obtaining an enzyme preparation that meets the application requirements, has a certain degree of purity and concentration. 

Method: Membrane separation technology is an effective separation method that utilizes semi-permeable membranes to achieve selective separation. It can be carried out at room temperature, avoiding any impact on enzyme activity, and the separated substances can retain their original properties. 

Specific steps: 

First, use ceramic microfiltration membranes or ultrafiltration membranes to separate the broken cells and large molecular substances such as the culture medium from the enzyme preparations. 

Then, nanofiltration membranes are used for concentration and purification, effectively removing small molecule impurities and most of the salts, thereby improving the purity of the product. 

Concentration technology: Membrane separation technology is also used for the concentration of enzyme preparations. Nanofiltration membrane elements have excellent performance at all temperatures, and can achieve effective removal of impurities and concentration even at low temperatures. 

Advantage: It addresses the issue of the impact of temperature on enzyme activity and the high energy consumption of traditional evaporation concentration. 

Refined: 

Objective: The purification process is designed to further enhance the purity and activity of the enzyme preparation, in order to meet specific application requirements. 

Method: The purification process may involve several steps, such as flocculation precipitation method, plate and frame filtration method, vacuum drying method, etc. These methods are selected based on the specific enzyme preparation and the required purity. 

Summary:

The filtration, separation, concentration and purification of biological enzyme preparations is a complex but crucial process, which ensures the purity and activity of the enzyme preparations, thereby enhancing their application effects in the fields of medicine, food, and chemical engineering. 

Membrane separation technology, as a new type of separation technology, has remarkable advantages in the field of enzyme preparations. It can be carried out at normal temperature, avoiding the impact on enzyme activity, and can achieve continuous operation, thereby improving production efficiency.
