[0028] Specifically, when the other side of the sieve plate 22 is tilted upward, the ingredients are transported into the cylinder, and with the vibration of the cylinder and the rolling of the ingredients on the sieve plate 22, particles with smaller particle sizes can pass through the sieve holes and fall into the lower hopper; when there are a lot of large-particle ingredients accumulated on the sieve plate 22, the other side of the sieve plate 22 is driven by the driving member 23 to tilt downward, and with the vibration of the cylinder, the large-particle ingredients can be discharged from the through hole 2a, without the need to manually clean the large-particle ingredients inside the cylinder, thereby reducing the workload of the operator.
