The inner wall of the working box 2 is rotatably connected to a first spiral conveying rod 33 on the side inside the pre-sterilization cylinder 31. The outer wall of the working box 2 is fixedly connected to a first drive motor 34 for driving the first spiral conveying rod 33 to rotate on the side close to the first spiral conveying rod 33. The outer wall of the pre-sterilization cylinder 31 is fixedly connected to an upper electric heating wire 35. The lower surface of the pre-sterilization cylinder 31 has a first lower opening 36 on the side away from the first upper opening 32. When using the equipment, first open the sealed box door 10, then put the material into the collection hopper 7 through the feed inlet 6, and then close the sealed box door 10 again. The material falls from the collection hopper 7 into the pre-sterilization cylinder 31 through the first upper opening 32. Turn on the first drive motor 34 to drive the first spiral conveyor rod 33 to rotate, so that the first spiral conveyor rod 33 moves the material towards the first lower opening 36. At the same time, turn on the electric heating wire 35 to heat and sterilize the material moving in the pre-sterilization cylinder 31 (the rotation speed of the first spiral conveyor rod 33 should be controlled so that the time from when the material falls into the pre-sterilization cylinder 31 to when it moves to the first lower opening 36 is sufficient to fully sterilize the material at high temperature, and the residence time of the material in the pre-sterilization cylinder 31 is not less than 30 minutes). The secondary sterilization assembly 5 includes a secondary sterilization cylinder 51 fixedly connected between the two sides of the inner wall of the support 1 (both the inner walls of the pre-sterilization cylinder 31 and the secondary sterilization cylinder 51 are coated with polytetrafluoroethylene). A second upper opening 52 is provided on the upper surface of the secondary sterilization cylinder 51 near the first lower opening 36.

The outer side walls of the first rotating shaft 42 and the second rotating shaft 43 are fixedly connected to the grinding rollers 44. The outer side wall of the working box 2 near the first rotating shaft 42 is fixedly connected to the crushing motor 45. The output end of the crushing motor 45 passes through the working box 2 and is fixedly connected to the first rotating shaft 42. The end of the first rotating shaft 42 away from the crushing motor 45 passes through the pulverizing box 41 and the working box 2 and is fixedly connected to the first gear 46. The end of the second rotating shaft 43 away from the crushing motor 45 passes through the pulverizing box 41 and the working box 2 and is fixedly connected to the second gear 47 that meshes with the first gear 46. After the material is initially sterilized, it falls through the first lower opening 36 and first falls into the crushing box 41 and then between the two grinding rollers 44. At the same time, the crushing motor 45 drives the first rotating shaft 42 and the first gear 46 to rotate. Furthermore, the first gear 46 drives the second gear 47 and the second rotating shaft 43 to rotate in the opposite direction to the first rotating shaft 42, thereby driving the two grinding rollers 44 to rotate and perform preliminary crushing on the material falling between the two grinding rollers 44 (mainly for crushing sealed containers). After initial crushing, the material continues to fall and enters the secondary sterilization cylinder 51 through the second upper opening 52. At the same time, the second drive motor 54 drives the second spiral conveyor rod 53 to rotate, moving the initially crushed material along the secondary sterilization cylinder 51 towards the second lower opening 56. During this process, the lower electric heating wire 55 is turned on to heat and sterilize the material moving in the secondary sterilization cylinder 51. (The rotation speed of the second spiral conveyor rod 53 should also be controlled so that the time from when the material falls into the secondary sterilization cylinder 51 to when it moves to the second lower opening 56 is sufficient to allow for a second high-temperature sterilization of the material, and the residence time of the material in the secondary sterilization cylinder 51 is not less than 30 minutes.)

After the material undergoes secondary sterilization, it moves to the second lower opening 56 and falls through it. During the falling process, the material first enters the degradation tube 83. At the same time, the crushing motor 93 drives the crushing rod 91 and the crushing blades 92 on the outer wall of the crushing rod 91 to rotate, which performs secondary crushing on the material passing through the degradation tube 83 (mainly crushing materials such as fiber plastics). The crushed material enters the degradation cylinder through the degradation port 82. At the same time, the fermentation agent spray head 86 sprays the fermentation agent in the fermentation agent storage box 85 into the degradation cylinder 81. The stirring motor 810 drives the stirring rod 88 and the stirring blades 89 to rotate, which stirs and ferments the fermentation agent and the material.

[0024] The implementation principle of this utility model is as follows: During operation, first open the sealed box door 10, then put the material into the collection hopper 7 through the feed inlet 6, and then close the sealed box door 10 again. The material falls from the collection hopper 7 into the pre-sterilization cylinder 31 through the first upper opening 32. Turn on the first drive motor 34 to drive the first spiral conveyor rod 33 to rotate, so that the first spiral conveyor rod 33 moves the material towards the first lower opening 36. At the same time, turn on the electric heating wire 35 to heat and sterilize the material moving in the pre-sterilization cylinder 31 (the speed of the first spiral conveyor rod 33 should be controlled so that the time from the material falling into the pre-sterilization cylinder 31 to moving to the first lower opening 36 is greater than 30 minutes, so as to fully sterilize the material at high temperature). After the material is initially sterilized, it falls through the first lower opening 36 and first falls into the crushing box 41 and then between the two grinding rollers 44. At the same time, the crushing motor 45 drives the first rotating shaft 42 and the first gear 46 to rotate. Furthermore, the first gear 46 drives the second gear 47 and the second rotating shaft 43 to rotate in the opposite direction to the first rotating shaft 42, thereby driving the two grinding rollers 44 to rotate and perform preliminary crushing on the material falling between the two grinding rollers 44 (mainly for crushing sealed containers). After initial crushing, the material continues to fall and enters the secondary sterilization cylinder 51 through the second upper opening 52. At the same time, the second drive motor 54 drives the second spiral conveyor rod 53 to rotate, moving the initially crushed material along the secondary sterilization cylinder 51 towards the second lower opening 56. During this process, the lower electric heating wire 55 is turned on to heat and sterilize the material moving inside the secondary sterilization cylinder 51 (the rotation speed of the second spiral conveyor rod 53 should also be controlled so that the time from the material falling into the secondary sterilization cylinder 51 to moving to the second lower opening 56 is greater than 30 minutes, so as to carry out a second thorough high-temperature sterilization of the material). After the material undergoes secondary sterilization, it moves to the second lower opening 56 and falls through it. During the falling process, the material first enters the degradation tube 83. At the same time, the crushing motor 93 drives the crushing rod 91 and the crushing blades 92 on the outer wall of the crushing rod 91 to rotate, which performs secondary crushing on the material passing through the degradation tube 83 (mainly crushing materials such as fiber plastics). The crushed material enters the degradation cylinder through the degradation port 82. At the same time, the fermentation agent spray head 86 sprays the fermentation agent in the fermentation agent storage box 85 into the degradation cylinder 81. The stirring motor 810 drives the stirring rod 88 and the stirring blades 89 to rotate, which stirs and ferments the fermentation agent and the material.
