Specifically, when the humidity value collected by the humidity collecting component 342 is smaller than the preset humidity value, the controller 500 determines that the moisture content in the stacking structure 400 is low, so that the humidity value collected by the humidity collecting component 342 at the top of the compost can 100 is smaller than the preset humidity value.

Specifically, when the first temperature value acquired by the first temperature acquisition component 341 is greater than the first preset temperature value, the controller 500 determines that the temperature in the stacking structure 400 is too high, resulting in the excessive heat of the stacking structure 400, and at this time, water needs to be sprayed to the stacking structure 400 to cool the stacking structure 400.

Specifically, when the second temperature value acquired by the second temperature acquisition component 101 is less than the second preset temperature value, the controller 500 determines that the ventilation condition in the circumferential direction of the stacking structure 400 is normal.

Specifically, when the humidity value collected by the humidity collection assembly 342 is greater than the preset humidity value, the controller 500 determines that the humidity of the stacking structure 400 is too high or the surrounding of the stacking structure 400 is blocked to cause the air humidity to exceed the preset value.

Specifically, when the first temperature value acquired by the first temperature acquisition component 341 is greater than the first preset temperature value, the controller 500 determines that the fermentation temperature of the stacking structure 400 is too high, or that the surrounding of the stacking structure 400 is blocked, so that the temperature in the top space of the compost can 100 exceeds the preset value.

Specifically, when the second temperature value acquired by the second temperature acquisition assembly 101 is greater than the second preset temperature value, the controller 500 determines that the temperature around the compost tank 100 is too high due to the blockage around the stacking structure 400.

In combination with the above judgment, the stirring assembly 300 is controlled to drive each stirring rod 330 to rotate, so that a gap is formed between the side wall of the composting pot 100 and the outer side wall of the stacking structure 400 by the stirring rods 330, the stirring rods 330 clear the periphery of the stacking structure 400, the ventilation property of the periphery of the stacking structure 400 is ensured, and the smooth performance of primary fermentation is ensured.

Specifically, the first period of time may be 3 to 10 minutes, and the ventilation between the sidewall of the compost tank 100 and the outer sidewall of the stacking structure 400 after the first period of time is natural airflow ventilation, so as to facilitate observation of the temperature change generated by the stacking structure 400 itself.
