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.
