[0038] It should be noted that the present invention is an electric meat mincer with replaceable blades. When in use, the operation of the drive motor 4 drives the feeding screw 8 in the meat feeding pipe 6 to rotate through the transmission box 3. When the feeding screw 8 rotates, it also drives the blade mounting ring 22 and the meat mincing blade 23 to rotate through the blade docking head 9. The meat to be minced is put into the meat feeding pipe 6 through the feeding pipe 7. Then the meat contacts the rotating feeding screw 8, so that the feeding screw 8 squeezes the meat and forces the meat to be pushed towards the meat mincing blade 23. A relative movement is generated between the rotating meat mincing blade 23 and the discharge screen plate 19, so as to mince the raw meat into granular form. The minced meat particles are discharged through the holes on the discharge screen plate 19.
