Heat-insulating bin for fermentation of soy sauce

Abstract

The invention discloses a heat-insulating bin for fermentation of soy sauce. The heat-insulating bin for fermentation of soy sauce comprises a fermentation bin, wherein an opening is formed in the upper end of the fermentation bin; a sealing cover is mounted on the opening; a filter layer is arranged in the fermentation bin; the fermentation bin is divided into a material cavity and a liquid cavity which are arranged vertically by the filter layer; an extracting device which penetrates through the material cavity from the opening and extends into the liquid cavity is mounted in the fermentation bin; an interlayer for filling hot water for heat insulation is arranged on the inner wall of the fermentation bin; and a water inlet and a water outlet are formed in the interlayer. In a fermentation process, fermentation failure and environment pollution due to leakage of fermentation liquor can be avoided, and the quality of the product is ensured effectively; and by arrangement of the filterlayer and the extracting device, raw materials and fermentation mature liquor are separated and extracted during fermentation, the utilization rate of the raw materials is high, the quality of the fermentation mature liquor is also high, an extracting mode is simple and convenient, and is easy to operate, environment pollution is avoided, moreover, the interlayer is arranged on the inner wall ofthe fermentation bin, thus, the fermentation bin is subjected to heat insulation by water bath heating, temperature difference change of the fermentation bin is relieved, and thus, soy sauce fermentation grains in the fermentation bin are heated uniformly, and are fermented consistently.

Description

technical field [0001] The invention relates to the field of food processing equipment, in particular to a soy sauce fermentation heat preservation bin. Background technique [0002] Fermentation is the core link in the brewing process of soy sauce. It is necessary to put the sauce into the fermentation chamber and add yeast for closed fermentation. During the whole fermentation process, it is necessary to keep the brewing tank at a suitable fermentation temperature; the structure of the fermentation chamber in the traditional brewing method It is unreasonable, the sealing effect is poor, and there are many defects in the fermentation process. It is easy to be polluted by miscellaneous bacteria such as film-forming yeast, which produces peculiar smell and leads to fermentation failure. In addition, the fermentation process is often infested by mosquitoes and flies, and the hygienic situation is worrying, which affects the quality of the product and leads to a decline in the ...

AI Technical Summary

Problems solved by technology

In the traditional process, a false bottom is set about 20cm away from the bottom in the tank, and heating equipment is installed under the false bottom, which can only be heated but not cooled, and the heating is uneven, and the heat preservation effect is poor, which may easily lead to inconsistent local fermentation
