Description

Strictly anaerobic water bath constant temperature solid state fermentation device

Technical Field

The utility model relates to a solid state fermentation technology, in particular to a strict anaerobic water bath constant temperature solid state fermentation device.

Background

The temperature is an important condition for fermenting the solid fermented grains of the white spirit, and is also a main characteristic of the regular expression of the fermented grains, and in the solid fermentation process, the temperature is a main factor influencing the fermentation. Under the present fermentation process conditions, the geothermal energy which changes in four seasons is mainly utilized to provide the fermentation temperature. Because of the environmental changes, the fermentation temperature is not easy to control, for example, in hot summer, the pit temperature is too high, fermented grains can become sour, in cold winter, the pit temperature is too low, the fermentation is slow, and in both cases, the pit yield is severely reduced. Therefore, in the fermentation of each stage of spring, summer, autumn and winter, corresponding measures are adopted to change the environment temperature, so that microorganisms in the cellar can survive and propagate in an optimal temperature range all the time.

In the solid state fermentation process of white spirit, the microbiota in the fermented grains are used for carrying out growth, propagation and metabolism activities by utilizing the nutrient substances, and heat is generated at the same time, so that the temperature of the pit is raised, and finally, the microbial action is slowed down along with the consumption of the nutrient substances and the replacement action of the microbial flora, and the quantity of the pit Chi Nare is reduced, so that the temperature of the pit is lowered. Therefore, the temperature of the fermented grains in the pit is different at different stages of the fermentation of the fermented grains. During long-term practice it was found that: for pits buried below the ground in traditional fermentation, the pit temperature can be affected by the ground temperature; different environmental temperatures in different seasons can also influence the temperature of the pit; in addition, the densities of the fermented grains and the air in different places in the same pit are different, so that the temperatures of different height layers of the same pit are also different. The temperature plays an important role in the fermentation process of the fermented grains, and the fermentation of the fermented grains needs a proper temperature.

However, the traditional lack of a temperature regulation method for fermented grains after being sealed and put into a cellar can only be released, or actions such as stopping fermentation can be adopted, so that the wine yield and the quality can be influenced, the production is seriously stopped, and the production cost is increased.
