[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-6 A kitchen waste processor includes a processing box 1, a crushing component, a mixing component, and a transfer component. The processing box 1 is provided with a processing chamber with an upper opening. The crushing component includes a crushing roller 2, a driving gear 3, a driven gear 4, a first motor 5, and a cover 6. Two sets of crushing rollers 2 are provided inside the processing chamber. The two sets of crushing rollers 2 pass through the processing box 1 and are respectively connected to the center of the driving gear 3 and the driven gear 4. The driving gear 3 and the driven gear 4 mesh. A cover 6 is also provided on the outside of the processing box 1 to cover the driving gear 3 and the driven gear 4. The output end of the first motor 5 passes through the cover 6 and is connected to the center of the driving gear 3.

[0034] The processing chamber is also equipped with a stirring assembly, which is located below the two sets of crushing rollers 2.

[0035] The bottom wall of the processing box 1 is also equipped with a transfer component.

[0036] The processing box 1 is equipped with a material inlet 23, which is also fitted with a hinged cover 24. During operation, the operator unfolds the C-shaped handle 25 (with a load-bearing capacity ≥30kg) hinged to the side wall of the processing box 1 and moves the equipment to the kitchen sink or a designated processing area (such as near a power source or drain). After placement, ensure the processing box 1 is level (calibrated with a level, horizontal deviation ≤1mm / m) to prevent material accumulation or uneven feeding by the transfer pump 14 due to tilting.

[0037] Open the hinged cover 24 on the feed inlet 23 (which can be flipped 180° for easy loading of large pieces of material), and pour the kitchen waste (leftovers, fruit peels, vegetable leaves, eggshells, etc.) into the processing chamber (the feed inlet 23 has a diameter ≥200mm and can accommodate whole cabbages, large pieces of radishes, etc.). Close the hinged cover 24 (to reduce the spread of odors), and start the first motor 5. The output of the first motor 5 (power 300-500W, speed 1500-2000rpm) drives the drive gear 3 inside the cover 6 to rotate. The drive gear 3 drives the driven gear 4 to rotate synchronously in the opposite direction through meshing (transmission ratio 1:1, speeds are completely synchronized).

[0038] Two sets of crushing rollers 2 rotate synchronously in opposite directions with the gears (speed 300-500 rpm). The serrated protrusions on the surface of the rollers interlock with each other. For soft waste (such as leftover rice and vegetable leaves), the protrusions can tear and squeeze to a particle diameter ≤5mm; for hard and brittle waste (such as eggshells and shrimp shells), the protrusions can crush to powder; for fibrous waste (such as celery fibroids), the protrusions can wrap around and cut off, avoiding the entanglement problem of traditional single roller crushing.

[0039] In this embodiment, the stirring assembly includes a second motor 7, a rotating shaft 8, a scraper 9, a flow guide shroud 10, and a support plate 11. The flow guide shroud 10 is in the shape of an inverted cone. The upper edge of the flow guide shroud 10 is provided with a support plate 11 connected to the side wall of the processing chamber. The output end of the second motor 7 passes through the bottom wall of the processing tank 1 and is connected to the rotating shaft 8. The rotating shaft 8 is also provided with a scraper 9 adapted to the inner wall of the flow guide shroud 10. The pulverized fine particles are stirred by gravity. The inverted conical truncated shroud 10 falls into the bottom of the processing chamber. The output end of the second motor 7 (power 100-200W, speed 300-500rpm) penetrates the bottom wall of the processing box 1, driving the rotating shaft 8 to rotate synchronously. The scraper 9 on the rotating shaft 8 (adapted to the inner wall of the shroud 10 and made of food-grade PP material) rotates with the rotating shaft 8, closely scraping off the attached oil and residue (such as rice grains and vegetable scraps) against the inner wall, ensuring that the residual amount on the inner wall of the shroud 10 is ≤0.5g.

[0040] The rotating scraper 9 stirs and breaks up the gathered material, preventing blockage of the subsequent feeding port due to material clumping (such as rice clumps in leftover food).

[0041] In this embodiment, the transfer assembly includes side plates 12, a support frame 13, a transfer pump 14, a transfer pipe 15, a transfer frame 16, and a closure. Side plates 12 are also provided on the left and right sides below the processing box 1. Support frames 13 are provided below the two sets of side plates 12. A transfer pump 14 is provided on the bottom wall of the processing box 1. A discharge port penetrating the bottom wall of the processing box 1 and the flow guide shroud 10 is provided above the transfer pump 14. A transfer pipe 15 penetrating the top wall of the support frame 13 is provided below the transfer pump 14. A closure connected to the support frame 13 is also provided on the front of the support frame 13.

[0042] The discharge port (30-50mm in diameter) at the bottom of the guide shroud 10 is connected to the inlet of the transfer pump 14. The homogenized material enters the transfer pump 14 (using a peristaltic pump or centrifugal pump with anti-clogging design) through the discharge port under the action of gravity and the negative pressure of the transfer pump 14. The transfer pump 14 pressurizes the material (pressure 0.2-0.3MPa) and transports it through the transfer pipe 15 (20-30mm in diameter) that runs through the top wall of the support frame 13, sealing it and conveying it to the transfer frame 16 (capacity 5-10L, suitable for daily household waste production) inside the support frame 13.

[0043] In this embodiment, the closure includes a support block 17, a worm gear 18, a worm 19, a screw 20, a handle 21, and an insert block 22. The front of the transfer frame 16 is also provided with a support block 17. The support block 17 has a movable cavity, in which the worm gear 18 and the worm 19 are arranged. The worm gear 18 and the worm 19 mesh. The worm 19 passes through the support block 17 and is connected to the handle 21. The screws 20 are symmetrically arranged on the left and right sides of the worm gear 18. The support block 17 has storage grooves on the left and right sides, in which the insert blocks 22 are arranged. One end of the insert block 22 is threadedly connected to the screw 20. The left and right sides of the bearing frame 13 have slots that are adapted to the insert blocks 22. When the transfer frame 16 is full, it can be observed through the observation window on the front of the transfer frame 16. The power of the device is turned off, and the handle 21 (with friction texture, grip friction ≥0.8) on the support block 17 on the front of the transfer frame 16 is rotated. Handle 21 drives worm 19 to rotate, worm 19 meshes with and drives worm wheel 18 to rotate synchronously, and screws 20 on both sides of worm wheel 18 (left-handed on the left and right-handed on the right) rotate with worm wheel 18, driving insert block 22 to retract from slot in support frame 13 into storage slot.

[0044] A method for treating kitchen waste, comprising the aforementioned kitchen waste treatment machine, includes the following steps:

[0045] Step 1: Lift the device to the designated location using handle 25;

[0046] Step 2: Open the hinged cover 24, start the first motor 5, the second motor 7 and the transfer pump 14. The first motor 5 drives the drive gear 3 inside the cover 6 to rotate, and the driven gear 4 rotates synchronously. The two sets of crushing rollers 2 crush the material. The second motor 7 drives the rotating shaft 8 to rotate. The scraper 9 stirs the material falling into the guide cover 10. The transfer pump 14 sends the stirred material into the transfer frame 16.

[0047] Step 3: Open the closure to remove the transfer frame 16 that carries the waste material for waste transfer.

[0048] Step 4: After cleaning the transfer box 16, reset the transfer box 16 and wait for the next food waste processing.
