Process for the separation of main material and supplementary material of vinegar grains

Abstract

The invention relates to a method for separating main material and auxiliary material of a vinegar residue, which belongs to the field of reproduction and utilization of vinegar derivatives, i.e. the vinegar residue. The method aims to sufficiently reutilize the vinegar residue by oven-drying and screening utilizable main material and auxiliary material of the vinegar residue. The separation method comprises the following steps: collecting a proper amount of vinegar residue; feeding into a drying device; oven-drying at 200 to 230 DEG C for 10 to 15 min in the first stage; oven-drying at 150 to 180 DEG C for 10 to 15 min in the second stage; oven-drying at 80 to 130 DEG C for 10 to 15 min in the third stage; oven-drying at 40 to 60 DEC G for 10 to 15 min in the fourth stage; spreading and airing for 2 to 3 h; separating the main material from the auxiliary material in a screening device; and stacking in a dry warehouse. The method has the advantages of simple and practical process, low cost and high efficiency and is suitable for reutilization of various kinds of vinegar.

Description

technical field [0001] The method for separating main and auxiliary materials of vinegar grains of the invention relates to the field of reproduction and utilization of vinegar derivatives, vinegar grains, in particular to a method for separating main and auxiliary materials of vinegar grains. Background technique [0002] There are many vinegar production enterprises in my country, especially in Shanxi. The derivatives of vinegar, vinegar grains, come from the residues left after brewing vinegar from rice, wheat, sorghum, etc. It is recorded in the Compendium of Materia Medica: barley vinegar grains, sour, slightly cold, non-toxic, The main ingredients in vinegar grains are sorghum and bran, and the auxiliary materials include rice bran and rice husk. At present, vinegar grains are used in the application field of vinegar grains without separation of main materials and auxiliary materials. The main materials and auxiliary materials of vinegar grains are separated. The field i...

Problems solved by technology

A small number of domestic enterprises use vinegar grains as raw materials for feed production, but most enterprises use vinegar grains as supplementary feed for livestock or as fertilizer for soil improvement or discarded, resulting in great waste

The reuse of vinegar grains produced by vinegar production has not attracted enough attention from vinegar production enterprises, and the reused vinegar grains have not undergone the separation process of main materials and auxiliary materials, so the utilization rate of vinegar grains is low and the effect is not good
