The control principle of the fermentation box with the high-precision temperature and humidity control system is as follows: when an operator needs to process food, the food is placed in the box body 1, and a processing temperature value, a processing humidity value and starting time are set through the human-computer interaction panel. After the setting is completed, the start button is triggered, and the controller 6 receives the start signal, the machining temperature value, the machining humidity value and the start time. After receiving the start signal, the controller 6 starts the temperature sensor 9, the humidity sensor 5, the temperature heating pipe 8, the humidity heating pipe 4, the temperature detection module 10, the rotation driver 13, and the second driving shaft 162, opens the second valve 174, and closes the first valve 173.

The temperature sensor 9, the humidity sensor 5, the temperature heating pipe 8, the humidity heating pipe 4, the temperature detection module 10 and the rotation driver 13 are started, so that each element is switched from a non-working state to a working state, the switching-on and the switching-off of an electrified switch of each element can be controlled, and the switching-on and the switching-off of the control end of each element can also be controlled directly. After the second driving shaft 162 is started, the second driving shaft 162 winds the connecting rope 164, and the connecting rope 164 pulls the blocking piece 163 until the blocking piece 163 winds onto the second driving shaft 162, so that the second driving shaft 162 is controlled to brake. At this time, the respective sub-chambers in the placing chamber 11 are independent of each other and separated by the baffle 163.

The controller 6 receives the temperature value in the cavity uploaded by the temperature detection module 10, the detection temperature value uploaded by the temperature sensor 9 and the humidity value in the cavity uploaded by the humidity sensor 5 in real time. And when the temperature value in the cavity is greater than the preset temperature set value, the electromagnet 724 is controlled to be electrified, so that the placing cavity 11 is communicated with the processing cavity 12.

The temperature set value is calculated by the controller 6 through a processing temperature value, and in the embodiment, the temperature set value is 5 ℃ higher than the processing temperature value; in other embodiments, 8 degrees celsius or 10 degrees celsius higher may be used. Before the electromagnet 724 is powered on, the processing chamber 12 and the placing chamber 11 are independent of each other, and air cannot be exchanged. The temperature heating pipe 8 only heats the temperature in the processing cavity 12, the rotary driver 13 drives the rotary fan blades 15 to rotate, the air flow in the processing cavity 12 is accelerated, the air temperature at each position in the processing cavity 12 is equal, and the uniformity of the temperature in the processing cavity 12 is improved.

After the processing cavity 12 and the placing cavity 11 are communicated, air flows mutually, hot air transfers heat to low-temperature air in the placing cavity 11, and the humidity value in the processing cavity 12 is gradually close to that in the placing cavity 11.

After the controller 6 receives the starting signal and the temperature value in the cavity is greater than the temperature set value for the first time, whether the detected temperature value is greater than the processing temperature value is judged. If the current value is larger than the preset value, controlling the electromagnet 724 in the corresponding air exchange tube 721 to be powered off; if the current value is less than the preset value, the electromagnet 724 in the corresponding ventilation pipe 721 is controlled to be electrified. Since the placing chamber 11 is divided into a plurality of sub-chambers, the controller 6 independently controls the temperature in each sub-chamber.

The controller 6 is also used for starting the humidity heating pipe 4 when the humidity in the cavity is smaller than a humidity set value; when the humidity value in the cavity is larger than the humidity set value, the humidity heating pipe 4 is braked. The humidity set value is calculated by the controller 6 through the process humidity value, and in the embodiment, the humidity set value is 5 times higher than the process humidity value; in other embodiments, the height may be 8 or 10.

The controller 6 is configured to determine whether the humidity reduction value is greater than a preset humidity reduction threshold value within a preset time threshold value after the humidity value in the chamber is greater than the humidity set value. If the power is larger than or equal to the preset duration threshold value, the power of the humidity heating pipe 4 is increased for the preset duration threshold value. After the placing cavity 11 is communicated with the processing cavity 12, the humidity in the placing cavity 11 is sharply reduced, and at the moment, the power of the humidity heating pipe 4 is increased, which is helpful for ensuring the humidity in the box body 1. Because the controller 6 will close the humidity heating pipe 4 after the humidity value in the chamber is greater than the humidity set value, the humidity in the placing chamber 11 is not easy to be greater than the processing humidity value.

The controller 6 is further configured to control the first valve 173 to open and simultaneously start the first driving shaft 161 to separate the end of the blocking piece 163 connected with the connecting rope 164 from the second driving shaft 162 when the detected temperature value is within the preset time threshold and the temperature decrease value exceeds the preset temperature decrease threshold. The storage box 17 stores high-temperature high-humidity air, and when the temperature value in the storage box suddenly drops a lot, the first valve 173 is opened to facilitate quick recovery of the temperature and humidity environment in the storage cavity 11.
