Lipid substances, such as ethyl palmitate, ethyl oleate, ethyl linoleate and the like, are inevitably generated in the wine brewing process, and the lipid substances can be dissolved in wine at normal temperature, but can be separated out from the wine at low temperature or in the case of cooling to form white floccules, so that the wine is turbid. In order to remove lipid substances from the wine body, the wine body is generally subjected to low-temperature freezing treatment to reduce the temperature of the wine body, so that the lipid substances are separated out from the wine body, and then the lipid substances are filtered by a diatomite filter. Although the diatomite filter has a good filtering effect on lipid substances in the wine body, the problem that part of diatomite particles are mixed into the wine body again and are not removed in time easily to cause blockage of a subsequent fine filter, influence on normal use of the fine filter or shorten the service life of the fine filter and increase production cost can not be avoided.
