Method for producing white spirit by use of waste Maotai-flavor distillers' grains

Abstract

The invention provides a method for producing white spirit by use of waste Maotai-flavor distillers' grains, which comprises the steps of (1) adding corn kernels into clear water and boiling to paste, cooling to normal temperature, adding glucoamylase and mixing uniformly, and sealing for 6-8 hours for later use; (2) dissipating heat of fresh distillers' grains to normal temperature for later use; (3) putting rice hulls accounting for 20% of the weight of the distillers' grains into a steamer, steaming for 20 minutes, taking out and dissipating heat to normal temperature for later use; (4) uniformly mixing the materials obtained by the steps (1), (2) and (3), and adding normal-temperature clear water accounting for 60% of the total weight, and mixing and stirring uniformly; (5) putting the mixture into a fermentation tank, and sealing and fermenting for 15 days; (6) extracting white spirit by a normal distillation process to obtain a finished product. By adopting the method provided by the invention, the distillers' grains after wine production are used again for producing white spirit, and the produced wine has pure taste; for storage, the previous wine and later wine are mixed to obtain the white spirit of about 50 degrees. The method has the characteristics of waste utilization, simple process, low cost and good effect.

Description

technical field [0001] The invention relates to a method for producing liquor, in particular to a method for producing liquor by utilizing waste Maotai-flavored lees and a preparation method thereof. Background technique [0002] Distiller's grains are the waste materials left after the production of liquor, and the raw materials for the production of liquor are mostly grains such as rice, sorghum, and corn. About 2% of cellulose also contains various nutrients such as amino acids and organic acids. Usually, distiller's grains can be used as livestock feed. However, with the emergence of special livestock feed, many farms have added distiller's grains as livestock feed for convenience. Feed nutrition cannot meet the requirements of aquaculture, and the utilization of distiller's grains is no longer widely used, making many distiller's grains waste, which not only causes waste of resources, but also directly involves the potential of enterprise benefits.

AI Technical Summary

Problems solved by technology

[0002] Distiller's grains are the waste materials left after the production of liquor, and the raw materials for producing liquor are mostly rice, sorghum, corn and other grains, and the produced distiller's grains generally contain about 8% of residual starch and about 3% of reducing sugar. About 2% of cellulose also contains various nutrients such as amino acids and organic acids. Normally, distiller's grains can be used as livestock feed, but with the emergence of special feed for livestock, many farms add distiller's grains as feed for convenience Feed nutrition cannot meet the requirements of breeding, and the use of distiller's grains is no longer widely used, making a lot of distiller's grains a waste, which not only causes a waste of resources, but also directly involves the potential of enterprise benefits
