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";
