Problems solved by technology

In the existing production, the conditions of entering the cellar, such as starch concentration and acidity, are mainly controlled to affect the microbial flora in the cellar, so as to achieve the purpose of indirectly controlling the temperature change trend in the cellar for Daqu wine production. Therefore, it is impossible to effectively control each fermentation. The temperature in the cellar during the stage affects the product quali

Embodiment 1

[0023] like figure 1 , figure 2 As shown, in this embodiment, multi-layer heat exchange tubes with horizontal tube diameters are arranged in the Daqu wine cellar pool. The tube spacing of each layer of heat exchange tubes in the horizontal direction is 60 cm, and the layer spacing of each layer of heat exchange tubes is 40 cm. All heat exchange tubes are connected in parallel.

[0024] The cooled grain troughs are hoisted into the cellar pond equipped with heat exchange tubes by driving in stages, and the cellar is stepped on, and the cellar is sealed after entering the cellar. In summer, 2 to 3 days after the grain grains enter the cellar, the cooling water that is 3°C to 10°C lower than the temperature in the cellar is passed into the cellar, so that the temperature in the cellar slowly rises to 33°C to 38°C in 8 to 15 days. ℃, until the temperature no longer rises, reduce the amount of cooling water, and finally stop the cooling water. When the temperature in the cellar...

Embodiment 2

[0027] like image 3 , Figure 4 As shown, in this embodiment, vertically arranged heat exchange plates are used as heat exchange components, and the heat exchange plates are arranged at a distance of 70 cm in the cellar, and the heat exchange plates are connected in parallel. After the installation of the heat exchange plate in the cellar is completed, the cooled grain troughs are hoisted into the cellar in stages by driving, and the cellar is stepped on, and the cellar is sealed after entering the cellar. 2 to 3 days after the winter grain grains are put into the cellar, the production waste hot water or hot water that is 3°C to 10°C higher than the temperature of the mother grains in the cellar is passed into the cellar, so that the temperature in the cellar rises to 8-15 days. After 29 ℃ ~ 38 ℃, reduce until stop feeding production waste hot water or hot water. When the temperature of the cellar begins to drop below the maximum temperature by 2°C to 3°C, the production w...

Abstract

The invention relates to a fermentation temperature control method in cellar pools for Daqu liquor production and belongs to the technical field of Daqu liquor production. The fermentation temperature control method realizes the fermentation temperature control inside the Daqu liquor producing cell pool in a heat exchanging way by arranging a heat exchanging device inside a Daqu liquor producing cell pool. When temperature of maternal fermented grains in the cell pool is too low or the temperature rises too slowly, hot water is charged, and heat is fed so as to heat the maternal fermented grains and shorten temperature rise time; when temperature of the maternal fermented grains in the cell pool is too high or the temperature rises too fast, cold water is charged, and heat-removing is carried out so as to cool the maternal fermented grains and reduce temperature rise speed; and in middle and late fermentation stage, waste hot water in workshop production is used for reserving temperature of the maternal fermented grains. The fermentation temperature control method of the cellar pools for Daqu liquor production can raise fermentation speed, shorten fermentation time and improve liquor quality.

Description

technical field [0001] The invention discloses a method for controlling the fermentation temperature in a cellar for producing Daqu wine, which mainly uses cold water or hot water to control the temperature in the cellar through heat exchange, and belongs to the technical field of Daqu wine production. Background technique [0002] Daqu liquor is a unique product in China, and its production process adopts the traditional solid-state fermentation distillation brewing technology. Studies have shown that the production and coordination of aroma components in Daqu liquor are the key factors affecting product quality, and the aroma-producing fermentation of Daqu liquor is the result of the synergistic action of many different types of microorganisms. Temperature has an important impact on the growth and metabolism of microorganisms. Different microorganisms have different sensitivities to temperature. The production and coordination of aroma components are closely related to the...
