Solid state fermentation device and solid state fermentation method

Abstract

The invention relates to a solid-state fermentation device and a solid-state fermentation method, and belongs to the technical field of white spirit brewing. Through the structural design of the solid-state fermentation device, the production mode of a traditional pit mud cellar is changed, a traditional brewing container becomes an automatic modern fermentation tank, and automatic transformation of brewing fermentation is facilitated; in the method, yellow water and alcohol fragrance are circulated up and down in the fermentation process, so that the fermented grains at the upper part and the lower part in the fermentation tank are in relatively consistent environmental conditions, and the fermentation quality of the fermented grains at the upper layer and the lower layer is kept consistent. Through staged control of heat preservation of the tank body, pit mud can be kept in a proper fermentation temperature stage, the influence of the external environment on the microbial fermentation process in the pit mud is reduced, and aroma-producing fermentation of pit mud is promoted. According to the invention, the innovation of an automatic production mode of a traditional mud pit fermentation mode is successfully realized, the production automation degree is improved, and the labor cost is reduced; meanwhile, the uniformity and consistency of fermentation are regulated and controlled, and the stability of fermentation quality is promoted.

Description

technical field [0001] The invention relates to a solid-state fermentation device and a solid-state fermentation method, belonging to the technical field of liquor brewing. Background technique [0002] Solid-state fermentation is a traditional fermentation technology in my country, and it is widely used in food fields such as liquor, soy sauce and vinegar in China, especially the liquor industry occupies an important position in my country's food industry. Traditional liquor is usually mixed with grain and koji medicine to make wine fermented grains, which are solid and filled into cellars for fermentation. Among them, Luzhou-flavor liquor occupies more than 70% of the liquor market in my country, and is accepted and loved by Guangfa consumers. Luzhou-flavor liquor is made in a mud cellar as a fermentation vessel, with sorghum and wheat as raw materials, and is made by traditional solid-state fermentation, and has a typical Luzhou-flavor style.

Problems solved by technology

At the same time, due to the lack of heat preservation and heat dissipation of the traditional mud pit pit, the temperature of the upper and lower layers of the traditional pit pit and the temperature of the inner and outer layers are different

Therefore, in the traditional mud pit pit, the environmental conditions such as temperature, moisture, and alcohol aroma substrate concentration of different levels of fermented grains are all different, resulting in different quality of fermented grains in different parts of the pit, and different The quality of cellars in local workshops is also different, which affects the stability of product quality and the stability of typical styles
