Problems solved by technology

[0003] However, the temperature drop in the above-mentioned cooling process is relatively rapid, which is not suitable for the fermentation of yellow rice wine.
At the same time, the investment cost of arranging coil pipes in the fermenter or jackets outside the fermenter is relatively high, thereby increasing the production cost

Embodiment Construction

[0022] The present invention relates to a process for cooling yellow rice wine fermented mash, which comprises the following process steps: first heat the yellow rice wine fermented mash to 30-32°C, and then open the rake, so that the warmed yellow rice wine fermented mash passes through a coaxial heat exchanger 1, And the temperature of the coaxial heat exchanger 1 is controlled at about 7.5° C., and the warm rice wine fermented mash passes through the coaxial heat exchanger 1 to obtain cool rice wine fermented mash. Wherein, the coaxial heat exchanger 1 is provided with freon as a cooling medium, and direct use of freon for evaporative refrigeration can effectively increase the cooling capacity.

[0023] Please refer to the attached figure 1 to attach image 3 As shown, it is specifically a kind of rice wine fermentation mash cooling equipment, which consists of a coaxial heat exchanger 1, a refrigerant compressor 2, a hot gas bypass valve 3, a water condenser 4, a solenoid...

Abstract

The invention relates to a process for cooling yellow wine fermented mash. The process comprises the following steps of: preserving temperature of the yellow wine fermented mash at 30-32 DEG C, harrowing, enabling the warm yellow wine fermented mash to pass through a coaxial heat exchanger, controlling the temperature of the coaxial heat exchanger about 7.5 DEG C, and enabling the warm yellow wine fermented mash to pass through the coaxial heat exchanger so as to obtain the cold yellow wine fermented mash. Through the process for cooling the yellow wine fermented mash, the temperature cooling is mild; the energy is saved, the consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a brewing process, in particular to a cooling process and equipment for rice wine fermented mash. Background technique [0002] The traditional saccharification and fermentation process needs to be kept warm at 30-32°C first, and then cooled by raking. In the cooling process, the chiller is used to cool the water first, and then the cold water is injected into the coil installed in the fermentation tank or (and) the jacket installed outside the fermentation tank to reduce the temperature of the fermented mash. [0003] Yet the cooling of above-mentioned cooling process is comparatively rapid, is not suitable for the fermentation of yellow rice wine. At the same time, the investment cost of arranging coil pipes in the fermenter or jackets outside the fermenter is relatively high, thereby increasing the production cost. [0004] Therefore, in order to solve the above-mentioned technical problems, it is really necessary to provi...
