Both fruit wine and fruit vinegar are produced by fermentation process. The raw liquid contains many solid protein, pectin, starch, plant fiber, macromolecular pigment, bacteria, yeast and other impurities. These impurities are semi-dissolved or exist in the form of macromolecules. Traditional filtration methods, such as diatomaceous earth and plate and frame filtration, cannot completely intercept impurities. Although no precipitation can be seen in a short period of time, temporary clarification can be achieved, but the gloss is not Well, within a certain period of time, due to the effects of electric charge, temperature, etc., these impurities will polymerize again, forming impurities that can be seen by the eyes, and will cause the filtrate to become turbid or precipitate. This is what we call:'Two Sub-precipitation phenomenon'.Fruit wine and fruit vinegar ultrafiltration membrane filtration equipment mainly uses the principle of selection and screening of polymer membrane materials to completely intercept these macromolecular impurities at one time, and through the cross-flow operation process, the impurities are not easily blocked on the surface of the membrane, and the effective ingredients follow The filtrate penetrates the surface of the membrane to achieve the separation and clarification effect of fruit wine and fruit vinegar, while also solving the problem of filter clogging.

Advantages of ultrafiltration membrane filtration of fruit wine and vinegar:
(1) The pore size of the ultrafiltration membrane is 1000Da-50nm, the impurities are separated thoroughly, and the filtrate is clear and transparent; (2) The material liquid is operated in a cross-flow mode, without adding filter aids, which can solve the pollution blockage (3) Pure physical process, no chemical reaction, and no change to the taste of the wine; (4) Run at room temperature without damaging the flavor; (5) Advanced modular design, convenient filter material replacement and simple operation; (6) Long-term storage will not be muddy, and there will be no "secondary precipitation";
