KQ＝Ae rt ；
in the formula, Q is the number of target theoretical yeasts corresponding to the weight of the input material, K is the target coefficient of a colony to be generated in the first high-temperature bin, A is the number of yeasts when the material is added, e is a natural number, r is the proliferation rate of the yeasts in the current environment, and t is a time value corresponding to the proliferation rate;
k in the above formula is set manually, which needs to satisfy the following conditions:
f' (K) is not less than 1, and 1/r. LnQ (1-K)/A is not less than T a ；
In the above, T a For the estimated minimum residence time of the material in the second high temperature bin, T a The average residence time is multiplied by a safety coefficient, and the value range of the safety coefficient is 0.4-0.8.
2. The machine of claim 1, wherein: the first high-temperature bin and the second high-temperature bin are closed bin bodies, the inner walls of the closed bin bodies are adhered with heat insulation material layers, and the adjacent inner walls of the first high-temperature bin and the second high-temperature bin are covered with double-layer heat insulation material layers.
3. The machine of claim 1, wherein: the feeding machine is a shaftless screw feeding machine which is vertically arranged.
4. The machine of claim 1, wherein: the squeezing dehydration device is obliquely arranged, and the included angle between the squeezing dehydration device and the ground is larger than 25 degrees and smaller than 45 degrees.
5. The machine of claim 4, wherein: the rotary bin conveyor is also obliquely arranged, and the axis of the rotary bin conveyor is parallel to the axis of the squeezing dehydration device.
6. The machine of claim 4, wherein: the axis of the feeding machine is parallel to the axis of the rotating bin conveyor.
7. The machine of claim 1, wherein: the first high-temperature bin and the second high-temperature bin are connected with a power device in the power bin through the same stirring main shaft.
8. The machine of claim 1, wherein: the circulating dehydration biochemical treatment machine is controlled by a field control unit, a temperature sensor, an air pressure sensor and a weight sensor are arranged in the first high-temperature bin and the second high-temperature bin, the temperature sensor, the air pressure sensor and the weight sensor are electrically connected with the field control unit, the field control unit is connected with a power device in the power bin, and the control end of the electric control door is electrically connected with the field control unit.
