Description

Maotai-flavor liquor production equipment

Technical Field

The invention relates to the field of Maotai-flavor liquor production, and particularly relates to Maotai-flavor liquor production equipment.

Background

Maotai-flavor liquor is one of three typical flavor liquor in China, and the unique process of the Maotai-flavor liquor makes the unique flavor characteristics of the Maotai-flavor liquor. One of the characteristics of the Maotai-flavor liquor is that the content of high boiling point substances, particularly organic acid, is very high, and the acid has the functions of enhancing the immunity of human bodies, softening blood vessels and the like, so that the Maotai-flavor liquor has a large consumer group and has huge market development potential. However, the Maotai-flavor liquor is very complex in process, long in production period, high in management difficulty, high in production cost and relatively slow in research on Maotai-flavor in industry, so that the Maotai-flavor liquor is slow to develop and only accounts for one percent of the whole liquor consumption.

Maotai-flavor liquor is an important type of liquor in China, represented by Maotai liquor and Lang liquor, and has the advantages of delicate Maotai-flavor, mellow liquor body, limpidity, transparency, light yellow color, long aftertaste and lasting fragrance of an empty cup. The traditional production process of Maotai-flavor liquor comprises 2 times of feeding, 9 times of stewing, 8 times of fermentation, 7 times of liquor taking, long-time storage and blending. The first feeding is called sand (sorghum raw material in the production of Maotai-flavor liquor is called sand), the second feeding is called brown sand, eight times of fermentation are needed after each feeding, each time of fermentation is about one month, and a large period is about 10 months. In the production process of the Maotai-flavor liquor, raw materials are crushed to be coarse, the ratio of the whole grains of the lower sand to the crushed grains is 80% to 20% (% is mass percent, and all the percentages refer to mass percent if not specifically stated below), the ratio of the whole grains of the coarse sand to the crushed grains is 70% to 30%, and the feeding amounts of the lower sand and the coarse sand respectively account for 50% of the total feeding amount. Distilling to obtain various types of wine base, storing in separate container, and aging for three years to make the wine mellow and soft. Blending the stored wine base, storing, and packaging to obtain the final product after qualified physical and chemical inspection and evaluation.

In the brewing process of the Maotai-flavor liquor, the grains are steamed in the sand, then the fermented grains are placed in a cellar for fermentation, the brown sand is discharged from the cellar for liquor steaming, the steamed liquor is called raw Sha liquor, the liquor yield is low, the raw Sha liquor is heavy in astringent taste, and the raw Sha liquor is diluted and then completely splashed back to the fermented grains of the brown sand and then participates in the fermentation again. Steaming coarse sha fermented grains, fermenting in cellar, and storing the wine called Huisha wine or Roisha wine, wherein the first wine should be stored separately and blended, and the tail should be poured back into fermented grains for fermentation. And (3) after the distillation of the Huisha liquor is finished, removing the fermented grains from the steamer without adding new materials, spreading for cooling, adding the shaggai liquor and the yeast powder, uniformly stirring and stacking, fermenting in a cellar for one month, taking out the liquor for distillation, and obtaining the liquor for the second time, wherein the liquor is more fragrant, mellow and slightly astringent than the shaggai liquor. The third, fourth and fifth wines, collectively called "Dahui wine", are fragrant and thick in quality, mellow in taste, full in body and free of foreign flavor. The liquor steamed by the sixth fermentation is called 'Xiaohui liquor', is mellow in quality, good in paste aroma and long in taste. The seventh steamed wine is "withered wine", also called Zhui-Chi wine, which is mellow and fragrant but slightly bitter and has strong taste. After the seventh wine is finished, the grains can be discarded or the wine can be taken by the next fermentation.

In the traditional production process of Maotai-flavor liquor, sorghum is required to be crushed and watered before sand and brown sand are added, the sorghum is steamed and fermented after sand is added, the brown sand after being watered is mixed, the existing watering process adopts natural soaking, the sorghum is required to be soaked for a long time in order to fully absorb water during watering every time, and the production efficiency is low to a certain extent.
