Basic Principle:Utilize the mass transfer mechanism of screening to achieve membrane separation processes. The filter elements of membrane separation equipment for macromolecular substances typically use ultrafiltration membrane modules. Ultrafiltration membranes can permeate small molecular solutions, retain components such as proteins, enzymes, viruses, colloids, and polysaccharides, and perform functions like concentrating protein solutions, desalination, and grade purification. Compared to traditional protein separation techniques (such as precipitation, distillation, extraction, and chromatography), membrane separation technology offers advantages such as operation at room temperature, low energy consumption, no need for chemical additives, wide selection range, and strong applicability.

Large molecule substance membrane separation equipment mainly includes hollow fiber ultrafiltration membranes and rolled ultrafiltration equipment. The main characteristics of both are listed in the table below.

Typical Application Fields:
Fermentate (including amino acids, antibiotics, active enzymes, etc.) filtration to remove impurities.
Juices (such as jujube, watermelon, and pear juices) filtered and clarified.
Sugar (starch sugar, polysaccharides, and monosaccharides) separation and clarification
Tea Beverage Filtration and Clarification
Seasonings (soy sauce and vinegar, etc.) filtration
Animal extracts (such as collagen) filtration
Filtered plant extracts (sugars and alcohols).
