[0033] The present invention provides an operating method for a kitchen waste bin that ferments kitchen waste into animal feed: Optionally, there are two feeding boxes 4, referred to as the first feeding box and the second feeding box. The first feeding box contains lactic acid, and the second feeding box contains bacterial culture. There are two water inlet branch pipes 22 and two water inlet valve bodies 221. The water inlet branch pipe 22 connected to the first feeding box is referred to as the first water inlet branch pipe and the first water inlet valve body, and the water inlet branch pipe 22 connected to the second feeding box is referred to as the second water inlet branch pipe and the second water inlet valve body. There are also two water outlet branch pipes 32. The one located at the higher position is referred to as the first water outlet branch pipe and the first water outlet valve body, and the one located at the lower position is referred to as the second water outlet branch pipe and the second water outlet valve body.

[0034] Step S1: After the inner barrel 1 is filled with a certain amount of plant waste, close the rotating door 20. The first feeding box contains lactic acid and the second feeding box contains bacteria. Press the start button to connect the working circuit and start the device. At this time, the display screen shows "Processing". Step S2: The main control board controls the main water inlet valve body 212 and the first branch water inlet valve body to open. Water in the kitchen will enter the first feed box through the main water inlet pipe 21 and the first branch water inlet pipe, and flush the lactic acid in it into the diversion ring 23, so that the water flows out from the annular opening 231 and flows down along the inner wall of the inner tank 11. At the same time, the first water flow sensor 211 will monitor the water flow rate through the main water outlet pipe 31 in real time. Step S3: When the water flow rate monitored by the first water flow sensor 211 received by the main control board reaches the set value, the main control board will control the main water inlet valve body 212 and the first water inlet valve body to close, and the main control board will send a signal to control the stirring motor 51 to start. The stirring motor 51 drives the stirring blade 54 to stir the mixture at a low speed. After stirring for a specified time, the main control board will send a signal to control the stirring motor 51 to stop. Step S4: The main control board then controls the heating component 6 to work. The heating component 6 starts to work at a higher power to heat the mixture contained in the inner liner 11. At the same time, the temperature and humidity sensor 50 monitors the temperature of the mixture in real time and transmits it to the main control board. When the temperature received by the main control board reaches 95 degrees, the timing starts. After the specified time is reached, the main control board sends a signal to stop the heating component 6 from heating. Step S5: After the main control board has been settling for a specified time, it controls the first outlet valve to open, so that oil and other impurities in the upper layer of the inner tank 11 are discharged from the outlet assembly 3. At the same time, the second water flow sensor 311 will monitor the water flow through the main outlet pipe 31 in real time and transmit it to the main control board. After the water flow monitored by the second water flow sensor 311 reaches the set value, the main control board closes the first outlet valve. Step S6: Next, the main control board will control the second outlet valve to open to drain the lower area of ​​the inner tank 11. After the water flow rate monitored by the second water flow sensor 311 received by the main control board reaches the set value, the second outlet valve will be closed. The heating component 6, the ventilation component 7 and the stirring motor 51 will be started. The ventilation component 7 will start to work to ventilate and exhaust the inner tank 11. The heating component 6 will start to work at a low power. The stirring blade 54 will stir the mixture at a low speed. Step S7: The temperature and humidity sensor 50 will monitor the humidity of the mixture in real time. When the humidity of the mixture is lower than the first set value, the heating component 6 stops working, while the stirring motor 51 and the ventilation component 7 continue to work until the temperature and humidity sensor 50 detects that the humidity of the mixture is lower than the second set value and then stops working.

[0035] Step S8: Then control the main water inlet valve body 212 and the second water inlet valve body to open. The water in the kitchen will pass through the main water inlet pipe 21 and the second water inlet branch pipe, and will enter the second feeding box, flushing the bacteria inside into the diversion ring 23, so that the water flows out from the annular opening 231 and flows down along the inner wall of the inner tank 11. At the same time, the first water flow sensor 211 will monitor the water flow rate through the main water outlet pipe 31 in real time. Step S9: When the water flow rate monitored by the first water flow sensor 211 received by the main control board reaches the set value, the main control board will control the main water inlet valve body 212 and the second water inlet valve body to close, and the main control board will send a signal to control the stirring motor 51 to start. The stirring motor 51 drives the stirring blade 54 to stir the mixture at a low speed. After stirring for a specified time, the main control board will send a signal to control the stirring motor 51 to stop. Step S10: At this time, the display screen shows "Fermentation in progress". The main control board starts timing and controls the heating component 6 to start working at a low power. The temperature and humidity sensor 50 monitors the temperature of the mixture in real time and adjusts the ventilation component 7 or the heating component 6 to work intermittently according to the temperature to maintain the temperature of the mixture at the fermentation temperature and ensure air permeability. At the same time, the stirring motor 51 works at a low speed for 10 minutes every hour to ensure that the mixture ferments evenly and fully.

[0036] Step S11: After the main control board sets the timer for the specified duration (which can be 15 hours), the heating component 6 starts to work at a higher power. At the same time, the stirring motor 51 drives the stirring blade 54 to stir the mixture at a lower speed. At this time, the display screen shows "Drying in progress". The temperature and humidity sensor 50 monitors the humidity of the mixture. When the humidity of the mixture is lower than a certain value, the heating component 6 stops working, and the stirring motor 51 works intermittently at a higher power for a certain period of time, driving the stirring blade 54 to break up the mixture.

[0037] Step S11: After the stirring motor 51 stops working, the display screen shows "Please remove". The user pulls out the plug 40, the foolproof switch disconnects the working circuit, and the user removes the fermented product. After removal, the user puts the plug 40 back into the discharge pipe 30, and the plug 40 presses down on the foolproof switch to connect the working circuit.

[0038] Step S12: The user presses the operation button, and the display shows "Cleaning in progress". The main water inlet valve 212, the first water inlet valve, and the second water inlet valve open, allowing clean water to enter the inner tank 11. When the water flow rate monitored by the first water flow sensor 211 received by the main control board reaches the set value, the main control board will control the main water inlet valve 212, the first water inlet valve, and the second water inlet valve to close. Then, the stirring motor 51 drives the stirring blade 54 to stir the water in the inner tank 11 at a low speed. After the specified time is reached, the stirring motor stops working. The first and second water outlet valves are opened to drain water. When the water flow rate monitored by the second water flow sensor 311 received by the main control board reaches the set value, the first and second water outlet valves are closed. Then, the stop button is pressed, and the machine stops working.

[0039] If the user observes an error in the fermentation process or another emergency situation through the transparent observation window 201, the user can press the emergency stop button to disconnect the working circuit and stop the machine from working.
