Embodiment 1

[0107] A method for processing distiller's grains, comprising the steps of:

[0108] 1) Soak the distiller's grains with alcohol, stir the distiller's grains every other day, and stop stirring after 2 weeks, so as to separate the chaff and cortex in the distiller's grains, and the remaining substances in the distiller's grains are mixed with the distiller's grains The leaching solvent forms an elution suspension;

[0109] 2) filtering and separating the chaff, the cortex and the eluting suspension in the distiller's grains;

[0110] 3) Ethanol in the eluted suspension is distilled off to obtain a distillation residue. Wherein, the weight percent of alcohol in the distillation residue is 5%.

Embodiment 2

[0112] The distillation residue obtained in Example 1 was subjected to detection analysis and storage time experiment. Store the distillation residue in an airtight container at room temperature. The corresponding indicators were measured before storage and after 2 years of storage, and the results are shown in Table 1.

[0113] As can be seen from the results, after the distillation residue is preserved for 2 years, its appearance has no difference, and there is no spoilage; the nutrient content it contains has no obvious change, and it can be seen that the distiller's grains after the treatment of Example 1 can be stored for at least 2 years. Affect the later high-value utilization.

Embodiment 3

[0117] A method for preparing vinegar from distiller's grains, comprising the following steps:

[0118] The distillation residue and chaff obtained in Example 1 are placed in a fermentation device, the weight ratio of the distillation residue and the chaff is 1:0.4, and Jiuqu balsam ester vinegar with 150% of the weight of the distillation residue fermented for 6 to 8 days is added Vinegar unstrained spirits and 80% of the weight of the distillation residue are grain-processed skin substances, mixed evenly, and fermented for 12 days to obtain a fermented product;

[0119] Transfer the fermented product into a glass tank, compact and fill it up, tighten the lid with a sealing plug, and seal it with gypsum and glue to ensure a tight seal, and age the unstrained spirits for 180 days in an environment of 2°C to 25°C to obtain aged unstrained spirits product;

[0120] Take 50% of the aged unstrained spirits product and put it into a smoked unstrained spirits tank, heat it with a s...

Abstract

The invention belongs to the biotechnology field, and particularly relates to a distillers' soluble treatment method which comprises the following steps of: soaking and eluting distillers' solubles by using a leaching solvent so as to separate out rice husks and skin substances in the distillers' solubles, and forming an elution suspension by residual substances in the distillers' solubles and the leaching solvent; filtering and separating the rice husks, the skin substances in the distillers' solubles as well as the elution suspension; and distilling to remove the leaching solvent in the elution suspension to obtain distillation residues. The problems of resource waste and environmental pollution in the existing distillers' soluble treatment technology are solved, and high-value utilization and clean production of the distillers' soluble are realized.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for processing distiller's grains, vinegar and a preparation method thereof. Background technique [0002] Distiller's grains are solid waste produced in the brewing process, and its output is huge. In 2016, the total production of liquor in my country reached 13.584 million tons, and from 2017 to 2018, an additional production capacity of 1.7214 million tons / year was added. According to conservative calculations, the production of distiller's grains alone will reach 50 million tons in 2020. Fresh distiller's grains contain a lot of nutrients, coupled with high water content, they are easily spoiled by microorganisms. The storage period of fresh grains should generally not exceed 2 to 3 days, otherwise a series of deterioration characteristics such as odor and hair growth will occur. The accumulation of a large number of distiller's grains will not only occupy...
