Bamboo absorbent charcoal for wine

Abstract

The invention relates to a bamboo active carbon for alcohol. Bamboo wood is used as a raw material and oxygen in air is used as an activating agent, and the bamboo active carbon for the alcohol contains more oxides and oxygenic groups and is prepared. The bamboo active carbon is used for removing impurity and abnormal taste in a mild wine and has good effect.

Description

1. Technical field [0001] The invention belongs to the manufacture of activated carbon, and prepares bamboo activated carbon containing more oxides and oxygen-containing groups, which is used for removing turbidity and odor in low-alcohol wine, and has achieved good results. 2. Technical background [0002] Activated carbon has a large specific surface and developed pore structure, and has good adsorption performance, and can simultaneously adsorb various substances such as ethyl caproate, hexyl acetate, ethyl oleate, ethyl linoleate, ethyl palmitate Esters etc. Activated carbon for wine requires activated carbon to have selective adsorption capacity, which can absorb ethyl oleate, ethyl linoleate, ethyl palmitate, etc. Esters are basically not adsorbed, and at the same time, the processed wine maintains the flavor of the original wine. When ordinary bamboo activated carbon and some activated carbons are used to remove turbidity in low-alcohol wine, they can absorb the tur...

AI Technical Summary

Problems solved by technology

The chemical method of bamboo activated carbon production is generally to crush bamboo materials into fine bamboo chips, and use phosphoric acid and zinc chloride as activators to produce powdery bamboo activated carbon with relatively developed pores. Because it still contains micropores, it will make wine in wine The loss of aroma is relatively large, and the presence of phosphorus and zinc will pollute the wine

Although the activated carbon molecular sieve can make the activated carbon basically free of micropores, the wine-flavored wine produced is still not ideal due to the chemical properties of the activated carbon surface.
