Embodiment

[0042] refer to Figure 1 to Figure 19 , the present embodiment provides a method for preparing pellet fuel by mixing the discarded pit mud and lees of Maotai flavored wine, the method is as follows:

[0043] 1) drying the discarded distiller's grains (moisture content of 80%-100%) of Maotai-flavored wine, so that the moisture content is 5%-10%;

[0044] 2) Pulverize the discarded pit mud of Maotai wine (blocky, with a moisture content of about 20%-30%);

[0045] 3) mixing the above-mentioned dried distiller's grains and crushed cellar mud, wherein the percentage by weight of distiller's grains and cellar mud is: distiller's grains 50%-60%, cellar mud 40%-50%;

[0046] 4) molding the above-mentioned mixed vinasse and pit mud press molding machine;

[0047] 5) The above-mentioned shaped pellet fuel is cooled and bagged.

[0048] This embodiment also provides a system for preparing pellet fuel by mixing the discarded pit mud and lees of Maotai-flavored wine, including a lees ...

Abstract

The invention provides a method and a system for preparing granular fuel by mixing waste pit mud and vinasse of Maotai-flavor liquor. The method comprises the following steps of: drying waste vinasseof Maotai-flavor liquor until the water content is 5%-10%; crushing waste pit mud of Maotai-flavor liquor; mixing the dried vinasse and the crushed pit mud, the weight percentages of the vinasse and the pit mud being as follows: 50%-60% of the vinasse and 40%-50% of the pit mud; molding the mixed vinasse and pit mud by using a pressure molding machine; and finally, cooling and bagging the formed granular fuel. The biomass granular fuel is prepared from wastes generated in the brewing process of Maotai-flavor liquor, so that the problem that waste pit mud and vinasse of Maotai-flavor liquor aredifficult to treat, pollute the environment and the like is solved, and recycling of the pit mud and the vinasse is realized. The invention belongs to the field of wine brewing waste recovery.

Description

technical field [0001] The invention relates to a method and a system for preparing pellet fuel by mixing the waste pit mud of Maotai-flavored wine and the lees, and belongs to the technical field of brewing. Background technique [0002] In the production process of Maotai-flavor liquor represented by Kweichow Moutai, the anaerobic fermentation process is the fermentation in the cellar, which requires the fermented grains to be completely sealed in the cellar. Among them, the pit mud is the clay used for sealing the pit, that is, the sealant of the fermented grains in the anaerobic fermentation surface of the pit pool. The pit mud used is taken from the purple mud within a few kilometers of Maotai Town. The purple mud has strong adhesion and sealing good sex characteristics. The production practice of Maotai-flavor liquor shows that the sealing mud not only plays a role in sealing the pit, but also has a close relationship with the wine quality of the upper fermented grain...
