Description

TECHNICAL FIELD

[0001] The utility model relates to a high-temperature Daqu preparation device. BACKGROUND

[0002] In the actual production process of high-temperature Daqu, the process measures taken to maintain high temperature are:

[0003] First, increase the amount of heat preservation materials. The whole Daqu block is almost wrapped with straw, and thick straw layers are covered between layers and blocks. The strong-flavor medium-temperature Daqu is not wrapped;

[0004] Second, increase the amount of Daqu. In the same size area of the Daqu room, the amount of Daqu stacked is 4-5 times that of the strong-flavor medium-temperature Daqu. For example, in the same area of the Daqu room, the amount of medium-temperature Daqu is 1500 kg, and the amount of high-temperature Daqu is 6000-7500 kg. Third, no gap between the Daqu blocks. When the medium-temperature Daqu is cultured, only one layer is stacked, and the blocks must be kept 2-3 cm apart (beneficial to heat dissipation and air circulation). The high-temperature Daqu is stacked 5-6 layers, and the blocks are tightly placed together without a gap (only a small amount of straw is used to separate the blocks, which is not beneficial to heat dissipation and air circulation).

[0005] These measures are to ensure the ideal temperature of high temperature koji-making, to promote the chemical, biochemical reactions, especially the enzymatic and non-enzymatic browning reactions, and to cultivate the microorganism population with high temperature resistance, in order to obtain more materials with soy sauce flavor. Some materials from raw materials, through complex microbial fermentation, not only generate some components with high content of aroma, but also form some components with trace amount of main aroma. For example, in the production of Maotai-flavor liquor, in addition to ester and alcohol components, trace amount of pyran and furan compounds with soy sauce and caramel flavor are also found. In the practice of high temperature koji-making, the aroma of koji at different temperature stages is different: the aroma of koji block just entering the koji room is the aroma of wheat, with grayish white color; when the temperature reaches 30-40℃, the aroma is sweet with light rice wine aroma (lees flavor), with light yellow color (the color of koji block surface, the same below); when the temperature reaches 50-58℃, the surface color of koji block turns to light brown, with obvious koji aroma; when the temperature of koji block reaches above 60℃, the surface color of koji block turns to dark brown or black, the cross section of koji block is golden yellow, and emits rich and elegant aroma (similar to the aroma of yellow rice cake, a kind of food made of glutinous rice and brown sugar by long time steaming. This aroma also exists in Maotai-flavor liquor, and the liquor with this obvious aroma and koji aroma is regarded as Maotai-flavor liquor); but this aroma is not soy sauce aroma; after the first turning of koji, with the increase of temperature and evaporation of water, the external color of koji block turns to brown, dark brown, black, and rarely golden yellow, the internal color turns to light brown, and the koji block emits rich koji aroma and light caramel aroma, which is called soy sauce aroma.

[0006] Compared with medium temperature koji, bacteria, spore bacteria and mould are much more in high temperature koji, but yeast is much more in medium temperature koji. Enzyme activity of medium temperature koji is much higher than that of high temperature koji. From the aspect of action condition, the optimum temperature of liquefied amylase produced by bacillus subtilis is 85-94℃, and the optimum temperature of saccharified amylase produced by aspergillus niger and aspergillus ruber is 60-65℃, both of which need high temperature. Wang Zongyan and Hu Yongsong of Sichuan University believe that "microorganisms in high temperature koji mainly come from koji mother, raw materials and environment, which is a complex microbial group. In finished koji, bacteria are absolutely dominant in quantity, only a small amount of mould exists, and yeast and actinomycetes are very few, which shows that high temperature koji-making makes the microbial system in koji transform to the direction of bacteria proliferation. High temperature bacteria are dominant in bacteria, which shows that high temperature koji-making is also an enrichment process of high temperature bacteria". Zhuang Mingyang and others also believe that "in the production process of Maotai-flavor liquor, Maillard reaction is related to microbial fermentation and enzyme system metabolized by microorganisms". All of these show that high temperature can cultivate high temperature microorganisms and various enzymes we need. However, the existing technology still uses ordinary koji room in koji-making process, and each koji material needs to be wrapped with straw, and thick straw layers are covered between layers and blocks, which all need manual operation, and the problem of large amount of manual operation exists. Practical new type content

[0007] Therefore, aiming at the above problems, the present application provides a high temperature koji preparation device, which solves the technical problem of large amount of manual operation in the existing technology in koji-making process.
