Description

Sand setting flexible closed system of white spirit fermentation tank

Technical Field

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

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. Among these, the most complex and important process is the fermentation process. The fermentation process of the Xiaoqu wine generates considerable heat, and the heat is derived from two aspects: one is respiratory heat and one is decomposition heat of fermentation. The heat can cause the temperature in the fermentation container to rise, if the fermentation temperature is too high and exceeds 40 ℃, the metabolism of rhizopus and yeast can be inhibited, the fermentation is slowed down and even stopped, so that the residual starch or residual sugar of the fermented grains is higher, the alcohol content is lower, the fermentation efficiency is reduced, and the direct result is that the wine yield is obviously reduced.

The fermentation process is mainly carried out in a sealed fermentation container, and the yeast converts sugar in the brewing raw material into alcohol in an anaerobic environment, so the fermentation container must be sealed in the fermentation process, oxygen in the air is prevented from entering, and the yeast is isolated from the air. 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. However, the existing fermentation container sealing technology inevitably has the following disadvantages:

(1) sealing liquid and sealant are adopted for auxiliary sealing, and because of small self weight, the whole volume can expand as the brewing raw materials generate gas at the beginning in the fermentation process for the large-area non-mechanically-processed fermentation container sealing joint surface; after several days, the whole volume of the wine brewing raw material is reduced along with the continuous decomposition of the wine brewing raw material to generate alcohol and water, so that the wine brewing raw material can continuously collapse downwards in the fermentation container, and the original sealed container has an empty space inside; in the face of the swelling and shrinking change of the whole volume of the brewing raw materials, the sealing liquid and the sealant can not be changed adaptively, so that the sealing effect is poor in persistence, the phenomenon of air leakage is easy to occur in the fermentation process, the operation is complex, and the brewing raw materials are easy to pollute;

(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;

(3) for a severe working environment, the probability of poor sealing caused by other various reasons is high;

(4) the recycling property of the sealing material is poor.

Referring to fig. 3, preferably, the pit 1 is a cuboid structure formed by cement and arranged underground, and the pit 1 has a length of 3.2-4.8 meters, a width of 3-3.2 meters and a depth of 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.

Referring to fig. 1, preferably, a fine sand interlayer 10 with a thickness of 0.4-0.7 m is arranged inside the wall of the pit 1.

In the embodiment, because the airtight flexible sealing cover 11 has the function of extending deformation, the flexible sealing cover 11 is selected to be combined with the fine sand 12 with certain mass as a sealing packing material, so that the filling mobility is good, the sealing packing material can better adapt to various deformations, and a better sealing state is kept. Because the clean fine sand 12 is different from yellow mud, the mud particles which are easy to mix in water are not contained, and the mud particles can not enter the pit 1 along with the water or the micro-gap with the particle size smaller than the fine sand to pollute grains for brewing wine. As the brewing raw materials generate gas at the beginning in the fermentation process, the whole volume can expand; after several days, the whole volume of the wine brewing raw material is reduced along with the continuous decomposition of the wine brewing raw material to generate alcohol and water, so that the wine brewing raw material can continuously collapse downwards in the fermentation container, and the internal fermentation space of the originally sealed container is dynamically changed; and facing to the change that the fermentation space is expanded and reduced, the flexible sealing cover 11 can also follow the deformation of adaptation shape, and the sealing effect of pressing and attaching between the flexible sealing cover 11 and the wall part of the cellar 1 is kept in real time.
