[0028] Furthermore, one end of the multiple feed pipes 501 is fixedly connected to the same manifold;

[0029] The top surface of the cylinder 1 is fixedly connected with a transfer box 3, and the feed end and the discharge end of the transfer box 3 are respectively connected to the output end of the manifold and the feed port of the cylinder 1 through a conduit;

[0030] Furthermore, a preliminary separation assembly is provided inside the transfer box 3, and the preliminary separation assembly includes a spiral conveying roller 301 fixedly connected to the inner wall of the bottom of the transfer box 3, and a plurality of grinding rollers 302 spirally distributed on the outer wall of the spiral conveying roller 301;

[0031] Preferably, one end of the grinding roller 302 is rotatably connected to the circumferential outer wall of the spiral conveying roller 301, and a gap of 0.3-3 cm is left between the outer wall of the grinding roller 302 and the spiral blade of the spiral conveying roller 301;

[0032] The discharge amount of ingredients in each material barrel 5 is accurately controlled by the metering valve 4, and the ingredients are transported to the transfer box 3 through the manifold. While the spiral blades of the spiral conveying roller 301 are automatically transported downward, the ingredients will come into contact with the grinding roller 302 above, and the grinding roller 302 will rotate under the action of friction and gravity, thereby preliminarily grinding the ingredients rolling on the spiral blades, so as to break up the lumps of ingredients.

[0034] Furthermore, a material chamber 101 is opened inside the cylinder 1, and the bottom inner wall of the material chamber 101 is rotatably connected to a stirring frame 8 that is evenly divided into a "human" shape when viewed from above; a motor [not shown in the figure] is fixedly connected to the bottom inner wall of the cylinder 1, and the output end of the motor is connected to the bottom end of the stirring frame 8 through a coupling; the stirring frame 8 is started by the motor to stir the various ingredients in the material chamber 101.
