Problems solved by technology

Chinese patent CN201910710248 discloses "a special distiller's grains-straw type bio-organic fertilizer for sorghum and its production method", which uses a certain proportion of strong-flavored, light-flavored, and sauce-flavored wine grains for organic fertilizer production. This method solves the problem of distiller's grains The problem of low potassium content and low C / N value of the organic fertilizer requires adjustment of the initial pH value of the fermented material. The fermentation cycle lasts for more than 50 days, and it is a special organic fertilizer for sorghum, which is not suitable for other crops, which greatly reduces the amount of organic fertilizer. application scenarios
[0004] Most of the methods for producing organic fertilizers from distiller’s grains disclosed in the above-mentioned patent documents require pretreatment of distiller’s grains in terms of acidity and moisture in the production process before they can be properly decomposed and fermented. , the above scheme will undoubtedly increase the production cost and enterprise burden

Abstract

The invention belongs to the technical field of chemical production, and relates to a production process for fermenting an organic fertilizer by using Maotai-flavor liquor vinasse. The production process comprises the following steps: (1) preparing a fermentation inoculant; (2) adding the fermentation inoculant in the step (1) into vinasse and auxiliary materials to prepare a fermentation raw material; and (3) transporting the fermentation raw materials obtained in the step (2) to a fermentation zone, and carrying out compost fermentation to obtain the organic fertilizer, the vinasse being Maotai-flavor liquor vinasse, and the fermentation inoculant being composed of Candida rugosa, Bacillus licheniformis, Paecilomyces variotii and Aspergillus fumigatus. According to the production process, the organic fertilizer production is performed on the Maotai-flavor Baijiu vinasse with characteristics of high acidity, high viscosity and degradation resistance under the conditions of natural pH,natural moisture and no additional chemical material adding, and the obtained organic fertilizer meets the national organic fertilizer standard (NY525-2012) and can be used for more scientifically and more effectively recycling and harmlessly utilizing the spent grains after the production of the Maotai-flavor liquor is finished, and has a wide application prospect in the Maotai-flavor liquor brewing industry.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and relates to a production process for fermenting organic fertilizer with Maotai-flavor liquor distiller's grains. Background technique [0002] Maotai-flavored solid liquor waste is the main by-product of the liquor industry, which has the characteristics of high acidity, high viscosity and refractory degradation, and has become the main solid waste of liquor production. The development of the liquor industry also urgently needs to break through the core and key technologies of clean production, resource utilization, harmlessness, and industrial utilization of waste waste biotransformation, and solve key issues such as disposal of waste waste in the production process of sauce-flavored liquor. [0003] According to statistics, the amount of discarded grains of Maotai-flavored liquor is about 5.5 times that of liquor production. Once it is not handled in time, the discarded grains wi...
