[0023] Reference Figure 1-7As shown, the food waste disposer of the present invention comprises a housing 1, a hopper 2 arranged at the upper end of the housing 1, and a crushing device 3 arranged in the housing 1. The crushing device 3 comprises a barrel 4, a screw 5 arranged in the barrel 4, and a motor 6 connected to one end of the screw 5. The discharge port 7 at the lower end of the hopper 2 is connected to the feed port 8 at one end of the barrel 4. The spiral outer wall of the front end of the screw 5 corresponding to the feed port 8 of the barrel 4 (i.e., below the discharge port 7 of the hopper 2) is provided with a sawtooth 9, and the outer wall of the barrel 4 is provided with a drying device 10. The sawtooth 9 can be used to crush some coarse food residues (such as bones, etc.). The drying device 10 is a cylindrical dryer, which wraps the outer wall of the barrel 4 as a whole, and can quickly dry the food residues on the surface of the screw 5. Different discharge effects can be achieved by setting different temperatures of the drying device 10. If dried at high temperature (around 200 degrees), the food residues can be completely dehydrated and the output can be used as animal feed. If dried at ultra-high temperature (around 350 degrees), the food residues can be nearly carbonized and can be used as fertilizer.

[0024] Preferably, the rear end of the screw 5 is provided with a fine grinding thread 11, and the rear end of the barrel 4 is provided with a barrel end cover 12, and the barrel end cover 12 is connected to the barrel 4 by a thread. The inner wall of the barrel end cover 12 is circumferentially arranged with straight teeth 24 that cooperate with the fine grinding thread 11, and the end surface of the barrel end cover 12 is arranged with a plurality of discharge holes 13, and the discharge holes 13 are conical. Through the cooperation of the fine grinding thread 11 and the straight teeth 24, the food residue is further finely ground, so that the food residue can be discharged from the smaller discharge hole 13 and formed into a thin strip shape or formed into a granular shape through processing, so as to facilitate recycling.

[0025] Preferably, a blade 17 is provided on the outer side of the barrel end cover 12, and the blade 17 is connected to a connecting shaft 18 at the rear end of the screw 5. The blade 17 rotates synchronously with the screw 5, and the blade 17 cuts the squeezed thin strips of food residue into granules during the rotation process, so that it is easier to recycle and is also convenient for some animals to eat.

[0026] Preferably, a plurality of drainage holes 14 are provided at the bottom of the discharge port 7 of the barrel 4. The screw 5 can separate the water slag through the drainage holes 14 during the crushing and extrusion process.

[0027] Preferably, mounting lugs 15 for connecting with the box body 1 and the hopper 2 are provided on both sides of the discharge port 7 of the barrel 4. The mounting lugs 15 are provided with screw holes, and bolts are screwed into the screw holes to achieve quick installation with the box body 1 and the hopper 2. To prevent water leakage, sealing gaskets can be provided on both sides of the mounting lugs 15.

[0028] Preferably, a flange 16 is provided on one side of the hopper 2, and the ends of the barrel 4 and the motor 6 are connected to the flange 16, so as to realize the rapid installation between the barrel 4, the hopper 2 and the motor 6.

[0029] Preferably, the screw 5 is conical in shape to improve the conveying and squeezing effect of food residues.

[0030] Preferably, the water receiving drawer 20 in the box body 1 is provided with a handshake groove 21 to facilitate the treatment of the separated water.

[0031] Preferably, a group of radial extrusion strips 22 are provided on the rear end surface of the screw 5, and the extrusion strips 22 have inclined surfaces 23. The extrusion strips 22 can promote the extrusion of food residues.

[0032] Preferably, a protective cover may be provided on the hopper 2 and the blade 17 to prevent the user's hands from being cut.

[0033] The above does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the structure and technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
