Under a certain pressure, when the raw material flows through the membrane surface, the many small pores on the membrane surface allow only water and small molecular substances to pass through and become permeate. Substances in the raw material with a volume larger than the micropores on the membrane surface are trapped on the inlet side of the membrane and become concentrate, thus achieving the purpose of separating and concentrating the raw material.

Chinese nameConcentration and separation equipment

TypeProcessing Machine

CharacteristicsSmall size and simple structure of the equipment. Application areas include enzyme preparations and protein products

Membrane concentration and separation technology is widely used in protein products, antibiotics, traditional Chinese medicine, fruit juice, dairy products, wastewater treatment, and other fields due to its advantages of not polluting the environment, saving manpower and resources.

The use of PSPP ultrafiltration membrane technology with different cut-off molecular weights for the separation and concentration of enzyme reagents, chondroitin sulfate, amino acids, peptides, fruit juice, animal and plant extracts, polysaccharides, glycerols, biological fermentation preparations, traditional Chinese medicine, proteins and other materials not only has no environmental pollution and saves manpower and material resources, but also does not require heating and operates at low temperatures without damaging the structure of the above substances, ensuring the original flavor of the materials and saving energy consumption

Separation and concentration are carried out at room temperature and low pressure, resulting in low energy consumption and lower operating costs of the equipment.

The equipment has a small volume and simple structure, so the investment cost is low.

The membrane separation process is just a simple pressurized transportation of liquid, with a simple process flow and easy operation and management.

The membrane, as a filtering medium, is a homogeneous continuum made of polymer materials. It is filtered purely by physical methods, and the substance does not undergo any qualitative changes during the separation process (i.e., it does not affect the molecular structure of the material).
