Fermentation pool for brewing soy sauce

Abstract

The invention relates to the technical field of soy sauce brewing, and in particular relates to a fermentation pool for brewing soy sauce. The fermentation pool for brewing the soy sauce comprises a fermentation pool; a heat insulation water tank used for dividing the fermentation pool into two parts is arranged in the middle of the fermentation pool; an overflow hole is formed in the heat insulation water tank; a heat insulation channel is arranged around the fermentation pool and the heat insulation water tank; the heat insulation channel is provided with a water inlet on the top of the fermentation pool and is provided with a water outlet at the bottom of the fermentation pool; an electric heating pipe is arranged in the heat insulation channel and is connected with a power supply. By adopting the technical scheme, the fermentation pool for brewing the soy sauce is good in heat insulation effect and is capable of guaranteeing the fermentation quality.

Description

technical field [0001] The invention relates to the technical field of brewing soy sauce, in particular to a fermentation tank for brewing soy sauce. Background technique [0002] The production process of brewed soy sauce mainly includes wheat selection, fried wheat, crushing, soybean meal cooking, mixing, inoculation, koji making, koji absorption, fermentation, pressing, filtration, blending, sterilization, filtration and packaging. [0003] At present, most domestic soy sauce manufacturers mainly use the solid-state low-salt fermentation method to produce soy sauce in the fermentation process. The soy sauce brewed by this process has the advantages of stable quality, good flavor, easy operation and management, and short fermentation cycle. The fermentation tank is a common fermentation equipment produced by solid-state low-salt fermentation method: the fermentation tank is generally square, rectangular, underground or semi-underground. There is a false bottom 20cm away fr...

Problems solved by technology

[0006] The fermentation tank for brewing soy sauce adopting the above-mentioned technical scheme has the following advantages: in the fermentation tanks on both sides of the heat preservation pool, the heat preservation water tank can effectively keep the heat in the middle of the two fermentation tanks, and at the same time, the heat preservation channel passes the fermentation tank and the heat preservation The pools are all surrounded, increasing the contact area between the heat preservation water and the fermentation tank, and at the same time, it also has a certain heat preservation effect on the water in the heat preservation pool. The electric heating tube in the heat preservation channel can heat the water in the heat preservation channel. Using the technology of the present invention The temperature difference effect of the fermentation tank for brewing soy sauce in the scheme is good, which can make the fermented grains of soy sauce in the fermentation tank be heated evenly, overcome the problems of large heat preservation temperature difference, poor heat preservation effect, and uneven heating of the fermented grains of soy sauce in the prior art, and ensure the fermentation quality
