The gas generated in the composting reaction of the kitchen waste is filtered by the activated carbon filter device 19 and discharged into the atmosphere. After the reaction stops, start the first motor 321, and the first motor 321 drives the left rotating shaft 311a and the right rotating shaft 312a to rotate respectively through the transmission mechanism, so that the left side door 315 and the right side door 316 move towards the direction away from each other. Then the discharge port 31a of the reaction chamber 31 is opened, and the kitchen waste after the composting reaction falls into the material storage box 17 under the action of gravity for reuse.

Because the bottom bent part of the left side door 315 overlaps with the bottom bent part of the right side door 316 and is in close contact, the contact area between the two is increased, the airtightness of the discharge port 31a can be improved, and the airtightness of the discharge port 31a can be improved to avoid The fertilizer formed by the kitchen waste in the composting reaction falls out or the leachate leaks to dirty the kitchen waste biochemical treatment device or pollute the environment. Simultaneously, because discharge opening 31a is arranged on the bottom of reaction chamber 31 and is formed on the entire length of reaction chamber 31 along the front-to-back direction, increases the discharge area of discharge opening 31a, makes the kitchen waste after composting reaction under the gravity It is easier to discharge under the action, which is beneficial to improve the discharge speed. In addition, since the front end of the drainage channel 33 is slightly higher than its rear end, the leachate formed by the kitchen waste in the composting reaction is discharged into the liquid storage tank 18 under the action of gravity, which can play a role of diversion, which is beneficial to The liquid drainage effect is improved, and the accumulation of liquid in the liquid drainage channel 33 is avoided.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention.
