Description

Fermentation brewing system of white spirit

Technical Field

The utility model relates to a xiaoqu white spirit brewage system especially relates to a fermentation vat of xiaoqu white spirit fermentation brewage system.

Background

Xiaoqu white spirit has a long history in China and is one of the main wine varieties with traditional characteristics. At present, the Xiaoqu liquor is generally brewed by adopting red sorghum, and the traditional brewing process of the Xiaoqu liquor is as follows: soaking → preliminary steaming → grain stewing → secondary steaming → spreading for cool → adding yeast → fungus culture in box → fermented grain tank → fermentation → distillation. In the brewing process of the Xiaoqu white spirit, the fermentation process is the most complex and important process, the fermentation process is mainly carried out in a sealed fermentation container, and because the saccharomycetes convert sugar in brewing raw materials into alcohol in an anaerobic environment, the fermentation container must be sealed in the fermentation process, so that oxygen in the air is prevented from entering, and the isolation of the saccharomycetes from the air is realized. The containers used at present are more, and comprise stone pottery jars, mud pottery jars, plastic barrels, plastic bags, cement cellar pools, cellars, stainless steel containers and the like. No matter which kind of container is adopted, various sealing modes are required to be adopted for sealing, such as sealing liquid and sealant are adopted for auxiliary sealing; if the traditional process is adopted, the wet yellow mud is generally used for sealing the gap at the top end of the pit to realize sealing. Sealing the red sorghum subjected to the treatment of the processes before fermentation in a fermentation container, and fermenting for several days to obtain yellow water; the yellow water is yellow slurry drenching water which is leaked from fermented grains in the white spirit cellar to the lower layer, and contains 1-2% of residual starch, 0.3-0.7% of residual sugar, 4-5% (V/V) of alcohol, acetic acid, humic substances, autolysate of yeast bacteria and the like. The yellow water is more acidic, the acidity is as high as about 5 degrees, and some domesticated caproic acid bacteria and precursor substances of the fragrance of white spirit are also provided, and the yellow water is a good material for manufacturing the artificial old cellar, promotes the old aging of a new cellar, and improves the quality of the spirit; it is usually collected and steamed in a common factory to obtain yellow wine, which is fermented together with wine tails. The fermentation container generally adopts a traditional pottery jar or a cement pond, and in order to be grounded, when mass production is carried out, most of the fermentation container adopts a cement pond which is formed by pouring cement after a pit is dug on the ground. The traditional process generally adopts manual operation, and the yellow water is fished out manually after the cellar is opened. However, the existing fermentation vessel sealing technology and yellow water extraction technology inevitably have the following disadvantages:

(2) yellow mud is adopted to seal the cellar, and because the yellow mud is exposed outside, the yellow mud becomes dry, cracks and even falls off after a long time, oxygen in the air enters a fermentation container, and the dry yellow mud can enter the fermentation container inevitably, so that the pollution of brewing raw materials is caused, time and labor are wasted, the workload of cleaning the cellar is increased, and the yellow mud is scattered to pollute the environment when the yellow mud is unsealed; moreover, the recycling property of the sealing material is poor;

(3) the sealing measures of the fermentation container during the brewing and fermentation process lead to the failure to monitor various data of the red sorghum in the fermentation process of the fermentation container;

(4) yellow water is inevitably accumulated after the fermentation pit is opened, so that a large-scale fermentation container is inevitably polluted, and the production environment of fermentation is influenced; the surrounding environment is also influenced when the yellow water is cleaned, such as the discharge of wastewater containing the yellow water and the volatilization of the odor of the yellow water; the labor intensity of the yellow water extraction is high, the labor cost is high, and the reduction of the manufacturing cost is not facilitated.

Preferably, the pit 1 is a cuboid structure which is arranged underground and is formed by pouring cement, a pipe laying groove 15 for laying a yellow water drainage pipe is dug beside the cement pit, and an overhead plate 15 for covering the pipe laying groove 15 is laid above the pipe laying groove 15; the length of the pit 1 is 3.2-4.8 meters, the width is 3-3.2 meters, and the depth is 1.2-1.8 meters; the top edge of the cellar pool 1 is provided with a rectangular enclosure wall 9, the height of the enclosure wall 9 is 0.2-0.8 m, and the thickness of the enclosure wall 9 is 0.5-0.8 m.

Preferably, a fine sand interlayer 10 with the thickness of 0.4-0.6 m is arranged inside the wall of the pit 1.

In this embodiment, the fermentation temperature in the pit 1 can be monitored by the temperature detector 8. During fermentation, rhizopus, saccharomycetes and other bacteria generate respiratory heat and fermentation decomposition heat, so that a brewing raw material can generate certain heat in the fermentation process in the pit 1, the heat can cause the temperature in the pit 1 to rise slowly, if the fermentation temperature is too high and exceeds more than 40 ℃, the metabolism of rhizopus and saccharomycetes can be inhibited, and the fermentation is slowed down or even stopped, so that the residual starch or residual sugar in fermented grains is higher, the alcohol content is lower, the fermentation efficiency is reduced, the direct result is that the wine is obviously reduced, the quality of finished wine is reduced, and the like, the easy lactic acid content is too high. When the fermentation temperature in the monitoring cellar 1 appears unusually, can carry out temperature regulation for cellar 1 through technical means, if during the high temperature, strengthen the ventilation and accelerate the heat dissipation of cellar 1, guarantee that whole fermentation process is controllable to the quality that makes the white spirit of producing obtains the sound guarantee.

In addition, in this embodiment, the fermentation temperature in the pit 1 can be monitored by the temperature detector 8. During fermentation, rhizopus, saccharomycetes and other bacteria generate respiratory heat and fermentation decomposition heat, so that a brewing raw material can generate certain heat in the fermentation process in the pit 1, the heat can cause the temperature in the pit 1 to rise slowly, if the fermentation temperature is too high and exceeds more than 40 ℃, the metabolism of rhizopus and saccharomycetes can be inhibited, and the fermentation is slowed down or even stopped, so that the residual starch or residual sugar in fermented grains is higher, the alcohol content is lower, the fermentation efficiency is reduced, the direct result is that the wine is obviously reduced, the quality of finished wine is reduced, and the like, the easy lactic acid content is too high. When the fermentation temperature in the monitoring cellar 1 appears unusually, can carry out temperature regulation for cellar 1 through technical means, if during the high temperature, strengthen the ventilation and accelerate the heat dissipation of cellar 1, guarantee that whole fermentation process is controllable to the quality that makes the white spirit of producing obtains the sound guarantee.

In this embodiment, the difference from the existing spirit brewing technology is mainly three processes, namely, a pit 1 sealing process, a yellow water and lees separation process in the pit 1, and a temperature monitoring process in the fermentation process, wherein the temperature monitoring process is integrated between the two processes. In addition, the brewing process of other white spirits is the same as the conventional one.

The sealing process of the pit 1 is implemented as follows: (1) stacking the brewing raw materials in a pit 1, and properly flattening and compacting the brewing raw material pile; (2) pushing a part of grains around the top of the brewing raw material pile to the top to form a brewing raw material pile with a flat and convex middle part; (3) then, a circle of inverted triangular groove belt 13 is drawn downwards around the top of the raked wine making raw material pile; (4) placing a temperature probe of a temperature detector 8 in a wine making raw material pile, and placing a reading meter of the temperature detector outside the pit 1; (5) laying a flexible sealing cover 11 on the top of the brewing raw material pile, wherein the flexible sealing cover 11 is tightly attached to the surface of the brewing raw material pile to completely cover the brewing raw material pile, and a circle of inverted triangular flexible groove belt 13 is also formed in a groove in the top of the brewing raw material pile by the flexible sealing cover 11; (6) then wetting the fine sand 12, uniformly paving the wetted fine sand 12 between the edge of the flexible sealing cover 11 and the wall part of the pit 1, and filling the flexible groove, wherein the height of the paved fine sand 12 is equal to or higher than the convex part at the top of the brewing raw material pile; (7) and finally, compacting the fine sand 12, so that the flexible sealing cover 11 and the wall part of the pit 1 are sealed through the fine sand 12, thereby forming a sand setting flexible closed system which can change along with the shape change of the brewing raw material pile, and ensuring that the sealing effect of the whole fermentation process is unchanged.

The process of the yellow water and vinasse separation process is as follows: (1) fermenting the brewing raw material in the pit 1 to generate yellow water, and collecting the yellow water at the bottom of the pit 1 under the action of gravity; (2) the yellow water can be extracted by opening the flow control valve 5, and is filtered by the floor drain 4 under the action of gravity, flows out of the water collection port 2 to the drain pipe 3, and is metered by the flowmeter 6; (3) and after the yellow water is drained, the vinasse can be elutriated from the pit 1.

The invention is not limited to the embodiments disclosed and described above, but rather, modifications and variations of the invention are possible within the scope of the invention as defined in the claims.
