Description

Technical Field

[0001] The utility model relates to the technical field of brewing equipment, in particular to a temperature controlling and grain moistening device for brewing. Background Art

[0002] In the winemaking process, grain moistening is a relatively important link. After being moderately crushed by the winemaking masters, the grains must be moistened with water before steaming and cooking. Taking sorghum as an example, after moistening, the sorghum grains expand, which can lay the foundation for subsequent steaming and gelatinization. Moistening the grains can not only make the starch granules in the sorghum absorb enough water, but also remove some substances that are prone to produce astringency during winemaking, thereby improving the quality of the wine.

[0003] The traditional manual grain moistening and mixing is to spread the grain on the ground to cool, moisten and mix the grain manually without using special grain moistening equipment. The traditional manual grain moistening and mixing of twelve wine steamers requires at least 24 workers. Not only is the labor consumption high and the work efficiency low, but there are also problems such as insufficient moisture absorption by the grain and uneven grain moistening, which seriously affect the improvement of the wine quality.
