Problems solved by technology

[0008] The above methods have a certain effect on solving the environmental pollution of winemaking solid waste, but the economic benefits are very small
In China, which has a very large liquor consumption group, the production of fermented and brewed seasoning liquid (natural essence) through the by-products and wastes of liquor self-fermentation will undoubtedly have a huge impact on social and economic benefits, especially the largest liquor. There are no relevant reports at home and abroad on the harmless treatment methods of solid waste disposal

Embodiment 1

[0052] Example 1 solid state fermentation stage

[0053] Put the discarded grains evenly in the liquor distiller, dry-steam them with 100°C saturated steam for 20 minutes, put them in a retort, and spread them in the air. When the temperature of the discarded grains drops to 60°C, sprinkle them with rehydrated and activated glucoamylase, and mix well; continue to spread in the air Cool down to 50°C, then sprinkle the cellulase after rehydration and activation, add acid protease, mix well; spread it out to cool down to 30°C, and then sprinkle the rehydration-activated high-temperature-resistant active dry yeast Saccharomyces cerevisiae activation solution , and the middle-temperature Daqu, which accounts for 2% of the weight of the grains, are mixed evenly, put into the cellar and fermented at a temperature of 28-30°C for 16 days to obtain grains.

[0054] The residue content of the discarded grains was 9.2% (W / W).

[0055] The rehydrated and activated glucoamylase is obtai...

Embodiment 2

[0061] Embodiment 2 solid-state fermentation stage

[0062] Put the discarded grains evenly in the liquor distiller, dry-steam with 110°C saturated steam for 15 minutes, place in a retort, and spread to dry. When the temperature of the discarded grains drops to 59°C, sprinkle the rehydrated activated glucoamylase and mix well; continue to spread to dry Cool down to 45°C, then sprinkle the rehydrated and activated cellulase, add acid protease, mix well; spread it out to cool down to 28°C, and then sprinkle the rehydrated and activated high temperature-resistant active dry yeast Saccharomyces cerevisiae activation solution , and the middle-temperature Daqu, which accounts for 2% of the weight of the grains, are mixed evenly, put into the cellar and fermented at a temperature of 30-33°C for 12 days to obtain grains.

[0063] The residue content of the discarded grains was 9.2% (W / W).

[0064] The rehydrated and activated glucoamylase is obtained by dissolving 20 times the glucoa...

Embodiment 3

[0073] Embodiment 3 solid-liquid combined fermentation stage

[0074] In the fermented grains prepared in Example 1, add 6% compound esterase and 8% high-temperature Dakoji by weight, mix well, stack at 35°C for 24 hours, then add 10% concentrated hexanoic acid to ferment liquid and 15% distilled grains wine, and finally fermented in the cellar for 8 days to get the fermented grains, the fermentation temperature is 36~40°C.

[0075] The compound esterase is formed by mixing Rhizopus and Monascus in a weight ratio of 7:4.

[0076] The caproic acid content of the concentrated caproic acid fermentation liquid is 28g / L, which is obtained from the fermentation workshop of Sichuan Yinfan Biotechnology Co., Ltd.

[0077] The distilled grains liquor is 57% vol, which is taken from the liquor experiment base of Sichuan Yinfan Biotechnology Co., Ltd.

Abstract

The invention discloses a resource and harmless processing method for biggest solid waste distiller's grain of traditional white spirit. The method comprises the following steps: adding diastatic enzyme, acid protease, thermostable active dry yeast, moderate-temperature yeast and cellulase into the distiller's grain of white spirit, and putting the mixture in a pit for solid state fermentation; adding rhizopus, red yeast, high-temperature yeast, distiller's grain wine and concentrated hexanoic acid fermentation liquid into the pit for solid-liquid combined fermentation; extracting and distilling the fermented grains to obtain natural essence for thick-flavor white spirit, natural essence for table vinegar and substance prepared into protein feed at the same time. The method disclosed by the invention has low cost, short production period, can process 35,000 tons of distiller's grain annually for the production scale of 8,000 t / a, reduces the pollutants CODcr, BOD5, SS and ammonia nitrogen discharged to environment, and plays a tremendous effect in the regional environmental protection. Meanwhile, the essence products prepared from the distiller's grain effectively improve the quality of white spirit and table vinegar, and sufficiently reflect the recycling value of the resource and harmless processing of solid waste of white spirit.

Description

technical field [0001] The invention relates to a resourceful and harmless treatment method for liquor brewing solid waste, which belongs to the field of environmental protection. Background technique [0002] We know that the production of traditional solid liquor is a multi-step process with a long production cycle. For every ton of 60% raw wine produced, 3-4 tons of waste will be thrown away. Due to the strong adsorption of precipitation, cellulose and hemicellulose in the waste grains, water and many organic matters are wrapped in the waste grains. Generally, after 2 days of waste dumping, due to the action of air and microorganisms, a large amount of organic wastewater seeps out, and its average CODcr is as high as 5.65*10 5 mg / L. Under normal circumstances, small and medium-sized wine companies sell when the waste has accumulated to a certain amount. The local water environment pollution will inevitably be caused during the residence time of waste waste. Large-scal...
