[0005] The Chinese invention patent with the authorized announcement number of CN 102181342 B discloses an artificial pit mud and its preparation method. The artificial pit mud is prepared by using yellow mud, sealing pit mud, high-quality pit mud, tail water, yellow water and distiller's grain pressing liquid. The liquid obtained after dehydration and extrusion of distiller's grains is used to prepare artificial pit mud, and most of the distiller's grains are still not utilized

Abstract

The invention belongs to the technical field of wine brewing, and provides a waste vinasse utilization method. The waste vinasse utilization method comprises the following steps: S1, after carrying out ultrasonic pretreatment on waste vinasse, uniformly mixing with double-round bottom vinasse, and fermenting in a fermentation tank to obtain a fermentation mixture; S2, dehydrating and extruding thefermentation mixture to obtain vinasse squeezed liquid and vinasse residues; S3, uniformly mixing the vinasse squeezed liquid, yellow water and tail water to obtain mixed liquid; S4, uniformly stirring yellow mud, pit skin mud, high-quality old pit mud, fresh pond mud, Daqu powder and vinasse residues, and then pouring the mixture into the mixed liquid in the step S3 to obtain raw mud; and S5, uniformly stirring the raw mud until the raw mud is soft and cooked, and fermenting the raw mud in a pit for 60-90 days to obtain artificial pit mud. The waste vinasse subjected to ultrasonic treatmentand the double-round bottom vinasse are mixed and fermented, the waste vinasse can provide a large number of nutritional ingredients for esterification microorganisms in the double-round bottom vinasse, esterification microorganism proliferation is facilitated, vinasse rich in esterification microorganisms is adopted for manufacturing the pit mud, the wine aroma level can be rich, and the aftertaste lasts long.

Description

technical field [0001] The invention belongs to the technical field of brewing, in particular to a method for utilizing waste distiller's grains. Background technique [0002] The distiller's grains are the mixed solids left after distilling the wine after fermenting the distiller's grains. Therefore, there are still quite a lot of unused protein, starch, fat and other components in the distiller's grains, which are similar to the nutrients in the distiller's grains, only in quantity There is a difference. In addition, due to various complex biochemical changes in the whole fermentation and brewing process, quite a lot of new components have also been produced, such as ribonucleic acid, purine, pyrimidine and other secondary metabolites, which are beneficial to the growth of microorganisms. Trace components, which greatly enhance the utilization value of distiller's grains. [0003] At present, the most common way to deal with discarded grains in China is as raw materials ...
