The control circuit board 70 analyzes the amount of decomposition enzymes required to be added to the kitchen waste according to the weight signal, and controls the time length of the action of the medicine supply driver 24 of the medicine adding device 20, so as to influence how much decomposition enzymes are pushed by the blades of the screw rod 26 of the medicine adding device 20 to leave from the medicine release opening 22b and release into the inner barrel 34, thereby accelerating the decomposition of the kitchen waste by the biochemical method.

The heater 40 continuously heats the kitchen waste in the inner tub 34 to facilitate the evaporation of water in the kitchen waste. The exhaust fan 64 of the air filter 60 continuously extracts the air, such as odor and moisture, in the inner tub 34, and the air is filtered by the filtering pipe 62 of the air filter 60 and then discharged out of the kitchen waste processing device 100, thereby achieving the effect of purifying the air. It should be noted that, in the process of heating the kitchen waste by the heater 40, the temperature is first raised to 50 degrees and the kitchen waste is heated at the temperature, after three hours, the control circuit board 70 controls the temperature of the heater 40 to be raised from 50 degrees to 80 degrees, and the heater 40 heats the kitchen waste at 80 degrees until the water content of the kitchen waste is lower than or equal to 15%, and the control circuit board 70 controls the weight sensor 36, the heater 40, the driving motor 52 of the stirrer 50 and the exhaust fan 64 of the air filter to stop operating, that is, the kitchen waste is converted into the organic fertilizer. Or the kitchen remainder processing device 100 will send out warning sound to remind the user to press the closing button 164, so as to form an open circuit between the control circuit board 70 and other components.

It should be noted that in the present embodiment, the water content of the kitchen waste is calculated by continuously obtaining the weight value of the kitchen waste by the weight sensor 36 during the operation of the heater 40, and transmitting the weight value to the control circuit board 70 as a weight signal. When the control circuit board 70 determines that the ratio of the weight value of the kitchen waste at the moment to the original weight value of the kitchen waste is less than or equal to 0.15, the control circuit board 70 determines that the water content of the kitchen waste is less than or equal to 15%. However, in practice, the water content of the kitchen waste can be calculated by other methods, but not limited to this.
