The first motor 210 drives the first rotating shaft 212, which rotates smoothly under the support of three first supports 211. The first rotating shaft 212 drives two blades 213 to rotate, cutting the raw materials.

The sieve plate 311 can return to the normal position through the connecting ring 312 and the spring 313, so that the sieve plate 311 can shake and screen the dried raw material. Then the raw material is taken out through the sieve hole 318 and the through hole 319.
