Problems solved by technology

Adopt these methods, the output that has is little and is difficult to form industrial batch production; Some have residue after processing, and product is difficult for keeping, and management department is unwilling to sell; Some total acid and total fat loss are more, affect the local flavor of wine, and fragrance is poor, The taste is light; some are costly; some processes are complex and difficult to master, and it is not easy to form industrial mass production. These clarification methods all have certain defects

Abstract

The invention discloses inorganic ceramic membrane technology used for baijiu clarification. The inorganic ceramic membrane technology used for baijiu clarification comprises following steps: 1, baijiu pretreatment, wherein a sodium hydroxide solution is added into baijiu stock solution, an obtained mixture is heated to boiling, and a diatomite filter is adopted for impurity removing; 2, inorganicceramic membrane is prepared; 3, baijiu is delivered through the inorganic ceramic membrane, wherein membrane filtration parameters are adjusted and controlled for filtering of the pretreated baijiu;4, the inorganic ceramic membrane is washed. According to the inorganic ceramic membrane technology, inorganic ceramic membrane is adopted for filtering clarification of baijiu; operation is simple;separation precision is high; the inorganic ceramic membrane technology is suitable for production of purified baijiu of baijiu factories of different sizes; suspended matters and sulfoprotein, whichare the sources of foreign flavor, can be blocked effectively; volatilization of aldehydes, sulfides, and free ammonia is accelerated; impurity removing and flavor enhancing are realized after filtering; intermolecular hydrophobic association of alcohol and water in baijiu stock solution is improved obviously; the obtained baijiu is gentle, fine, mellow, thick, and sweet in taste.

Description

technical field [0001] The invention belongs to the technical field of inorganic ceramic membranes, and in particular relates to an inorganic ceramic membrane technology for liquor clarification. Background technique [0002] When the alcohol content of liquor is above 50°, it is relatively clear and transparent. When it is below 50°, as the alcohol content decreases, the transparency also decreases, and even slightly turbid. This will appear when white wine is reduced in concentration, because the higher alcohols, higher fatty acids and their esters in white wine, mainly ethyl palmitate, ethyl oleate, and ethyl linoleate are present in the wine. The solubility decreases and precipitates. This phenomenon is more obvious when producing low-alcohol wine. The solubility of the above-mentioned higher fatty acid ethyl esters in liquor is not only related to the alcohol content, but also has a great relationship with the temperature. As the temperature decreases, so does their ...
