Detailed Description

This is explained in detail below with reference to fig. 1.

The utility model discloses a solve the lees when carrying out solid state fermentation the difference of the several fermentation attribute between the different position levels that meet, provide a fermenting installation with water content detects the function, it is used for the fermentation process of lees. The core of vinasse fermentation is a process of microbial growth and propagation, uniform microbial settlement can be generated at each part of vinasse through good fermentation, a large amount of microbial enzymes generated by the microbes hydrolyze starch, protein and other substances in the vinasse, so that a large amount of ethanol, organic acid and lipid are generated, a large amount of low boiling point substances such as carbon dioxide and the like are discharged, and part of the ethanol, the organic acid and the lipid are necessary substances for brewing white spirit and are one of the keys for finally obtaining the finished white spirit. The environment of the fermentation, in turn, affects the effectiveness of the growth of the microorganisms, where the environmental impact may have a variety of factors, one of which is a factor in spatial location. According to the research, the physicochemical indexes of the fermented grains in the fermentation pit are different at least on the vertical level, specifically, on the acidity: lower layer > middle layer > upper layer; at the moisture content: lower layer > middle layer > upper layer; in terms of starch content: the upper layer > the middle layer > the lower layer. This indicates that in the same fermentation space, the closer to the vertically lower part of the space, the better the fermentation. Meanwhile, in the horizontal dimension, the part closer to the wall of the pit is better in fermentation than the part closer to the middle. The main reason is that the wall of the pit is usually coated with pit mud containing a plurality of fermentation strains, the vinasse close to the wall can be in better contact with caproic acid bacteria and other functional bacteria, and the propagation condition of various functional bacteria at the part is relatively better, so that the fermentation condition of the part is better than that of the vinasse part relatively closer to the middle; the fermentation distribution in the vertical direction has a similar reason, and the vinasse on the upper layer can only contact the pit mud and the functional bacteria in the pit mud less based on the gravity and the overall linear growth direction of the fungi, so the fermentation effect is poorer than that of the middle layer and the lower layer. Based on the above fermentation principle, it can be known that different fermentation effects can cause great differences in the relevant attributes of the fermented products, for example, the concentrations of key output substrates such as ethanol, organic acids, lipids, dissolved oxygen, etc. are different, and the fermentation conditions of each vinasse part are different due to different microorganism growth conditions caused by different positions, so that the physical and chemical properties of distilled liquors obtained through a subsequent distillation process are different, and the problems of yield reduction or yield quality reduction, etc. are caused.
