Problems solved by technology

For a long time, most wineries have generally not effectively utilized the discarded waste and discarded it directly, which not only wastes resources, but also causes environmental pollution
[0003] With the enhancement of people's awareness of resource conservation and environmental protection, people began to pay attention to the development of the utilization value of wastes and other substances, such as making esterification liquid, string steaming liquid, returning cellar fermentation liquid, etc., but the above methods still have low extraction utilization rate. , improve the shortcomings of unstable product quality
[0004] In recent years, with the supercritical CO 2 The development of extraction technology, there is the use of supercritical CO 2 Related reports about extracting aroma substances from fermented by-products such as waste grains, yellow water, and bottom pot water have improved the extraction rate of aroma substances, but they have the disadvantage of high recycling costs

example 1

[0030] Example 1 adopts the inventive method to produce liquor

[0031] Spread out 8000kg of grains from the retort and let it cool down to 35°C, then start to sprinkle high-temperature Daqu, the amount of koji used is 400kg, mix evenly, so that the waste is evenly adhered to high-temperature Daqu powder, and control the stacking temperature at 28°C to 32°C . The piled fermented grains are piled up from the center outward, covering one layer after another, and start to pile up. The diameter of the pile is 4m and the height is 1.4m.

[0032] After the temperature at 20cm from the surface of the heap reaches 55°C, the pile is broken, and the broken grains are spread to cool to 32°C. Before the grains are put into the cellar, the wall of the cellar is sprayed with hot water higher than 85°C, and each layer of the pile is broken. After the unstrained spirits are mixed evenly, they are fermented in a stone wall and mud bottom cellar. After the accumulation of bad grains is finis...

[0039] Example 2 adopts the inventive method to produce liquor

[0040] Spread out 8000kg of grains from the retort and let it cool down to 32°C, then start spreading high-temperature Daqu, the amount of koji used is 100kg, mix evenly, so that the waste is evenly adhered to high-temperature Daqu powder, and control the stacking temperature at 28°C to 32°C . The piled fermented grains are piled up from the center outward, covering one layer after another, and start to pile up. The diameter of the pile is 5m and the height is 1.2m.

[0041]After the temperature at 20cm from the surface of the heap reaches 50°C, the pile is broken, and the broken grains are spread to cool to 25°C. Before the grains are put into the cellar, the wall of the cellar is sprayed with hot water higher than 85°C, and each layer of the pile is broken.

Abstract

The invention relates to a method for producing white spirit by utilizing waste spent grains, belonging the wine-making field. The technical problem solved by the invention is to provide a method for producing high quality white spirit by utilizing waste spent grains. The method comprises the following steps: 1) distiller's yeast is added in waste spent grains to mix evenly and stack; 2) when the temperature of the waste spent grains 20cm below the surface of the heap is 45-65 DEG C, the heap is broken and cooled to 25-35 DEG C, the waste spent grains are placed in a cellar to ferment; and 3) after the fermentation, the product is discharged from the cellar and then distilled to obtain the white spirit. The method uses the white spirit waste spent grains with rich nutrients as fermentation source and adopts the piling production technology of the Maotai-flavor liquor; the obtained white spirit has the delicate and mellow taste of the luzhou-flavor liquor and the mellow and refreshing taste and fragrant Maotai-flavor of the Maotai-flavor liquor; and the product quality reaches the level of the high-quality wine. By adopting the method, the consumption of grains can be reduced and the yield of the high-quality wine can be increased, thus the method has wide application prospect.

Description

technical field [0001] The invention relates to a method for producing liquor by using discarded grains, and belongs to the field of brewing. Background technique [0002] Distilled grains are fermented grains made from fermented grains and fermented by solid-state distillation to extract wine, which contains rich aroma substances of wine body and a large amount of organic nutrients such as starch, fat, and protein. For a long time, most distilleries have generally not effectively utilized the discarded waste and discarded it directly, which not only wastes resources, but also causes environmental pollution. [0003] With the enhancement of people's awareness of resource conservation and environmental protection, people began to pay attention to the development of the utilization value of wastes and other substances, such as making esterification liquid, string steaming liquid, returning cellar fermentation liquid, etc., but the above methods still have low extraction utiliz...
