Embodiment Construction

[0015] The method for resource utilization of brewing waste tail water of the present invention comprises the following steps: packing a porous material into a column as an adsorption column, passing the tail water through the adsorption column, using wine, non-toxic alcohol or ester as an eluent to elute, collecting and washing dehydration.

[0016] Wherein, the main component of the porous substance is inorganic carbon, the porosity is not less than 50%, and the specific surface area is not less than 1m 2 / g.

[0017] Wherein, the inorganic carbon is powdered activated carbon or granular activated carbon.

[0018] Among them, the adsorption saturation of the tail water passing through the adsorption column is judged according to the following criteria: the relative difference between the content of the main extracted components in the effluent and the influent after the tail water passes through the adsorption column is less than 5%, which can be considered as adsorption sa...

Abstract

The invention relates to a method for recycling tail water of brewing wastes, belonging to the technical fields of brewing and environment protection. The invention aims at providing a method for extracting trace components for wine from the tail water of the brewing wastes. The method for extracting the trace components for wine from the tail water of the brewing wastes comprises the following steps: filling porous substances to a column to be used as an adsorption column, passing the tail water by the adsorption column, eluting by wine, non-toxic alcohol or ester as an eluent, and collecting the eluate. According to the invention, the available components in the tail water are extracted in a pure physical process by the method, so that the method has an important application value in the brewing industry.

Description

technical field [0001] The invention relates to a method for resource utilization of winemaking waste tail water, and belongs to the technical field of winemaking. Background technique [0002] Tail water is the discarded part in the production process of liquor. It is produced by steaming grain or catching acid after extracting the liquor tail. Therefore, tail water is the waste produced by fermentation and distillation process. There are many trace components in the tail water. Through analysis, it is known that the tail water contains acids, esters, acetic acid, furfural, 2,3-butanediol, β-phenylethanol and heterocycles and other skeleton components and trace components required in liquor. , These substances are produced in the winemaking process, if the substances in the tail water can be recycled, the economic benefits are very obvious. [0003] At present, there are no relevant reports on extracting useful components from tail water and further utilizing them. Conte...
