Description
Technical field
The present invention relates to a kind of method and apparatus controlling Chinese liquor solid-state fermentation temperature, belong to liquor production technical field.
Technical background
Chinese liquor solid fermentation is with pit for carrier, with grain unstrained spirits for raw material, and inoculation, multiple-microorganism synergism naturally.Solid, liquid, gas (grain unstrained spirits, fermentation liquid, fermentation gas) three-phase has carried out the material energy metabolism process of series of complex in pit.Showing after deliberation, the fermenting and producing of grain unstrained spirits is produced material impact by temperature.Various microbial growth metabolism in grain unstrained spirits sweat are had material impact by temperature, high temperature stacking fermentation technique, kind and the quantity of microorganism in cellar for storing things can be enriched, kind and the content of the metabolite of microorganism can be increased, the formation of fragrance matter is played an important role by the control of temperature, and the fermentation temperature in cellar for storing things is required also different by simultaneously different fermentation times.So fermentation temperature is conducive to formation and the coordination of liquor flavor material in control pit, make distilled spirit fragrance more quiet and tastefully laid out, fine and smooth；Taste is more plentiful, mellow, soft, long.Therefore, control fermentation temperature in Chinese liquor pit the product quality of deduction Chinese liquor is significant, and fermentation temperature control method is both for whole pit and carries out rough overall control in existing Chinese liquor pit, temperature control effect is not ideal enough, and the yield of the Chinese liquor produced and quality yet suffer from the space improved.
Summary of the invention
Applicant finds in a large amount of research practices: the temperature of each position and different fermentations time period in pit in sweat, the poor unstrained spirits fermentation of diverse location is caused very big diversity, also affects the quality of production of Chinese liquor simultaneously.In pit, the poor unstrained spirits fermentation diversity of three positions, upper, middle and lower is very big, and the diversity of the poor unstrained spirits fermentation in edge and centre position is also bigger.In summer, high temperature causes the material excess accumulations such as the acid in pit, aldehyde, affects the quality of Chinese liquor, thus can not produce, in winter, low temperature causes longer fermentation times, affects the formation of the fragrance matter of Chinese liquor simultaneously.Zones of different in pit is respectively adopted different temperature curves carry out temperature control can improve product quality and shorten fermentation time.
Based on the studies above, the invention provides a kind of method of fermentation temperature in new control white spirit solid state fermentation cellar.
The present invention is achieved through the following technical solutions:
A kind of control the method for fermentation temperature in white spirit solid state fermentation cellar, fermentation pit is divided into some regions, by arranging temperature control equipment in fermentation pit, regional is carried out respectively temperature control.By zones of different being carried out respectively temperature control, to adapt to the diverse location environment minute differences to temperature requirement in pit, ensure that each position is all in optimum fermentation temp, thus improving product quality, and effectively shorten fermentation time, when fermenting in the winter time, the effect shortening fermentation time is particularly evident；When fermenting summer, control fermentation temperature, it is to avoid the effect of abnormal fermentation is also particularly evident.
Alternately, in above-mentioned control white spirit solid state fermentation cellar in the method for fermentation temperature, it is performed continuously over temperature control at the bottom of the pit wall of fermentation pit and pit.
Alternately, in above-mentioned control white spirit solid state fermentation cellar in the method for fermentation temperature, in winter, before charging feedstock, first will be preheating to 15 ~ 20 DEG C with pit wall bottom pit.In winter, owing to weather is colder, it is likely to occur freezeout in cellar for storing things, so directly affect grain unstrained spirits and enter cellar for storing things, meanwhile, temperature is relatively low also can extend fermentation time, and such winter is by the efficiency of impact grain unstrained spirits fermentation, can effectively shorten fermentation time by preheating, and can solve that temperature is too low causes pit to freeze thus causing the problem that cannot be carried out of fermenting.
