Embodiment 1

[0025] The pilot koji room of the koji-making workshop was selected as the test room to carry out the experiment of the method of making koji with medium and high temperature Daqu without overturning. The koji room entered at the same time was selected as the control room, and the fermentation process of the control room was carried out according to the traditional Daqu fermentation method. After the fermentation starts, the fan is turned on to ensure that the whole fermentation process of the test room is in a state of air circulation.

[0026] According to the room temperature and humidity, carbon dioxide and Daqu temperature changes in the test room, the researchers adjusted the fan frequency and valve opening from time to time to ensure the normal fermentation of Daqu.

[0027] The first is the constant room entry stage. When Daqu enters the room, adjust the fresh air valve to 25%, adjust the fan frequency to 20Hz, and turn on the external heating source to keep the tempera...

Embodiment 2

[0041] The 2 pilot-scale koji rooms in the koji making workshop of Yibin Liuchixiang Liquor Industry were selected as the test koji room to carry out the test of the method of making koji with medium and high temperature Daqu without turning over the koji. Two traditional koji rooms that entered the room at the same time were selected as the control room. trials. When the fermentation is over, the results are as follows:

[0043]

[0044] Table 3: Comparison table of Penicillium infection rate in the second experiment

[0045]

[0046] From the above two tests, it can be seen that the moisture in the traditional koji room is higher than that of the test group, and Penicillium infection is prone to occur. The method of making koji with medium and high temperature Daqu without turning over the koji of the present invention has better water control, and there is basically no Penicilliu...

Abstract

The invention discloses a Non-turning making method of medium-high temperature Daqu. In a heat preservation yeast room, the pressed yeast blocks are stacked on a frame or a shelf and are uniformly placed in the yeast room, and a fan and an air pipe are introduced; in the fermentation process of Daqu, according to the temperature change of the yeast center, the yeast heating is sequentially divided into six stages, namely a constant room entering stage, a low-temperature heating stage, a medium-temperature heating stage, a high-temperature constant stage, a medium-high-temperature cooling stage and a low-temperature constant stage; wherein the temperature control of each stage is realized by adjusting the frequency of a fresh air valve, the frequency of a fan and an external heat source. Environmental parameters of all positions of the yeast room are adjusted in an air circulation mode, it is guaranteed that environments where yeast blocks are located basically have no difference, and normal fermentation of yeast in the yeast room is achieved.

Description

technical field [0001] The invention relates to the field of Daqu production, in particular to a medium-high temperature Daqu koji making method without overturning. Background technique [0002] Chinese liquor has a history of thousands of years. With the continuous development of science and technology, the liquor industry has also begun to transform from traditional handicrafts to mechanization. Thanks to the efforts of pioneers in the industry, Daqu’s simple processes such as wheat moistening and crushing, water mixing, and buckling molding have been mechanized, but fermentation management processes such as koji turning, ventilation and moisture removal are still at the traditional level. During the fermentation process of Daqu, due to the differences in the environment of each location of the koji room, the temperature rise rate of Daqu at different locations is inconsistent. It is necessary to turn the koji upside down, turn the four sides in the middle, and turn the m...
