Desilting flexible sealing system of Baijiu fermenting tank

Abstract

The invention discloses a desilting flexible sealing system of a Baijiu fermenting tank. The desilting flexible sealing system comprises a cellar tank used as the fermenting tank, a cellar cover for covering fermenting raw materials in the cellar tank, and a sealed filling and pressing material for sealing the cellar cover and the wall part of the cellar tank. The desilting flexible sealing systemis characterized in that the cellar cover is a flexible sealing cover of which the shape is attached to the wall part of the cellar tank; the sealed filling and pressing material is fine sand which is heaped at the edge of the flexible sealing cover; and a moving type temperature measuring device for detecting the temperature of the cellar tank is arranged in the cellar tank. The desilting flexible sealing system has the advantages that the whole system is scientific and simple in structure, easy to operate and cheap in cost; the flexible sealing cover cooperates with the fine sand to form ashape self-adapting desilting flexible sealing system, so that in the whole fermenting process, the sealing effect of the cellar tank is guaranteed to be kept good; and through the moving type temperature measuring device, in the whole fermenting process, the temperature is controllable, the fermentation quality is guaranteed, and the quality control of Xiaoqu Baijiu is facilitated.

Description

technical field [0001] The invention relates to a liquor fermentation tank, in particular to a closed system of a liquor fermentation tank. Background technique [0002] Xiaoqu baijiu has a long history in my country and is one of the main wines with traditional characteristics. At present, Xiaoqu baijiu is generally brewed with red sorghum. The traditional brewing process of Xiaoqu baijiu is as follows: soaking → initial steaming → stewing grain → re-steaming → cooling → adding koji → cultivating bacteria in a box → fermented grains → fermentation → distillation. Among them, the most complex and important process is the fermentation process. During the fermentation process of Xiaoqu wine, considerable heat is generated, which comes from two sources: one is respiratory heat, and the other is fermentation decomposition heat. These heats will cause the temperature in the fermentation container to rise. If the fermentation temperature is too high, exceeding 40°C, it will inhi...

AI Technical Summary

Problems solved by technology

[0004] (1) Sealing liquid and sealant are used as auxiliary seals. Due to the small weight, for the joint surface of a large-area, non-machined fermentation container, since the raw materials for winemaking will generate gas at the beginning during the fermentation process, the overall volume will decrease. After a few days, as the brewing raw materials are continuously decomposed to produce alcohol and water, the overall volume will become smaller, so that the brewing raw materials will continue to "collapse" downwards in the fermentation container, causing the original sealed container to appear empty inside In the face of the expansion and contraction of the overall volume of wine-making raw materials, the sealing liquid and sealant cannot be adaptively changed, resulting in poor sealing effect continuity and prone to "air leakage" during the fermentation process, and The operation is complicated, and it is easy to cause pollution to the raw materials for brewing;

[0005] (2) Use yellow mud to seal the cellar. Because the yellow mud is exposed outside, it will become dry, cracked, or even fall off after a long time, so that the oxygen in the air will enter the fermentation container, and the dry yellow mud will inevitably enter the fermentation container. Pollution of wine-making raw materials, time-consuming and labor-intensive, and increased workload of cleaning cellar pools, yellow mud scattered when unsealed will also pollute the environment;

[0006] (3) For the harsh working environment, there is a high probability of poor sealing due to various other reasons;

[0007] (4) Poor reusability of sealing materials
