Liquor Membrane Filtration

Application of membrane separation technology in removing impurity from Baijiu1

The main raw material of baijiu is grain, which is made from starch or sugar raw materials into fermented grains or fermented and then distilled. The production of baijiu in my country has a long history and is a traditional beverage in China. In recent years, membrane separation technology has been gradually applied in the Liquormaking industry, especially in the application of turbidity removal of low-alcohol liquor, which can not only remove the turbid substances in the Liquor body, but also does not affect the flavor of the Liquor, and is increasingly valued by Liquorries. Today, the editor of Bona Bio will introduce the application of membrane separation technology in the removal of impurities in liquor.

The traditional method of filtration and clarification of liquor is to use activated carbon adsorption and then filter the activated carbon through a horizontal diatomaceous earth filter for clarification. Diatomite filtration equipment has the phenomenon of low filtration accuracy, easy soil leakage, cumbersome operation, and unstable filtration effect, while powdered activated carbon is a very small particle, which is easy to leak through the diatomite layer, making liquor with carbon particles, The diatomaceous earth itself has a general filtering effect, so the gloss of the liquor is not very ideal. Bona Bio’s liquor separation membrane filtration equipment screens and intercepts the Liquor body at the molecular level, selectively removes macromolecular impurities in the Liquor, and solves the “secondary precipitation”, return to turbidity and poor light transmittance of the Liquor body and other problems, improve the Liquor quality and corporate image, and bring real economic benefits to the enterprise.

Advantages of Membrane Separation Technology for Liquor Impurity Removal:

1. Use ultrafiltration equipment to remove turbidity, improve the clarity of liquor, and reduce harmful substances such as fusel oil;
2. The design of cross-flow operation can solve the problem of pollution and blockage without adding filter aids;
3. Pure physical process, no chemical reaction, does not change the taste of the Liquor;
4. Remove the pungent and bitter taste of liquor, reduce the irritating fragrance, highlight the main ester fragrance, and achieve the effect of removing impurities and enhancing fragrance;
5. Unlike traditional filtration, which uses filter media to control the filtration precision, membrane filtration does not require filter media, so there is no need to replace the filter media frequently, and there is no loss due to the media taking away the product and the pollution of the product by replacing the filter media;
6. Made of 304 or 316L stainless steel, in line with QS certification requirements.
