Abstract

Relating to the technical field of liquor processing, the invention discloses a filtration and clarification process for baijiu. The process includes: firstly adding diatomite into baijiu, conductingstirring, standing, centrifuging and precipitate removing to obtain coarse filtered liquor, then adding a chitosan solution into the coarse filtered liquor, mixing the substances evenly, conducting ultrasonic treatment, then adding an active adsorbent, and carrying out stirring, standing, centrifuging and filtering. The preparation method of the active adsorbent includes: grinding attapulgite andsodium silicate, then performing high temperature calcination, mixing the treated mixture with shrimp shell powder, then performing grinding and granulation, and finally adding the granules into a sodium hydroxide solution for soaking treatment. The process provided by the invention can remove calcium ions, magnesium ions and iron ions from liquor targetedly, effectively prevents excessive solid content and fishy smell of the product, and improves the product quality.

Description

【Technical field】 [0001] The invention relates to the technical field of liquor processing, in particular to a filtration and clarification process for liquor. 【Background technique】 [0002] Filtration and clarification is one of the important links in the production and processing of liquor. In addition to alcohol and water, newly brewed liquor also contains insoluble substances, proteins, tannins, pigments, colloids and other components, which are prone to browning, loss of light, turbidity and precipitation during storage. Filtration and clarification will shorten the shelf life and reduce the quality. At present, diatomite, bentonite, chitosan or gelatin are generally used in liquor production to settle and remove impurities, or to filter and clarify by natural clarification, which have good results. [0003] Debao County, Guangxi is located in the Shishan area. Its underground mineral content is rich, and its water is mostly hard water. The content of calcium ions, m...
