Description

Technical Field

[0001] This utility model relates to the field of gelatin preparation filter technology, specifically to a multi-stage gelatin filtration device. Background Technology

[0002] Gelatin is made from the collagen in the bones and skin of animals such as pigs, cattle, and sheep through denaturation and degradation. During gelatin production, the gelatin solution is pressurized and passed through a filter media layer to trap impurities including insoluble inorganic salts, bone or skin fragments, and thermosetting protein aggregates, thereby improving the purity and transparency of the gelatin.
