Description

Technical Field

[0001] The utility model relates to the technical field of gelatin membrane concentration, in particular to a gelatin membrane concentration ultrafiltration processing device. Background Art

[0002] Gelatin has no fixed structure and relative molecular weight. It is partially degraded from collagen in connective tissues such as animal skin, bone, fascia, and myometrium to form white or light yellow, translucent, slightly shiny flakes or powder particles. It is a colorless, tasteless, non-volatile, transparent and hard amorphous substance. It is soluble in hot water but insoluble in cold water, but it can slowly absorb water to swell and soften. Gelatin can absorb water equivalent to 5-10 times its weight. Gelatin is one of the most important natural biopolymer materials and has been widely used in food, medicine and chemical industries. Membrane concentration is a technology that reforms traditional processes to achieve efficient purification and concentration. It uses the difference in molecular weight between the active ingredient and the liquid to achieve directional separation and achieve the effect of concentration. Compared with traditional heating concentration, it has the advantages of low energy consumption, room temperature, and little impact on the product.

[0003] Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, small molecular solutes and solvents are allowed to pass through a hollow fiber ultrafiltration membrane with a certain pore size, while large molecular solutes cannot pass through and remain on one side of the hollow fiber ultrafiltration membrane, thereby partially purifying the large molecular substances. Existing gelatin membrane concentration devices often use filter screens, heating and other filtering devices during filtration, which have poor effects and are easy to damage the gelatin components, thereby reducing the quality of the gelatin concentrate.
