After cereal after filter screen 201 handles falls to the storeroom, when cereal piles up to sheltering from first proximity switch 4011, main control unit 8 makes first control valve 1012 close, and makes sieve motor 2025 stop working shakes to inform the user by audible-visual annunciator 7, whether or not in order to remind the user to need to grind. When needing to grind, main controller 8 opens second control valve 4013, and cereal piles up to grinding storehouse 402 in, when second proximity switch 4021 is sheltered from by cereal, second control valve 4013 closed this moment, and main controller 8 makes grinding motor 4031 rotate, and drives grinding blade 4032 and grind cereal. After grinding, the main controller 8 controls the third control valve 4022 to open, and when the powdered grain is accumulated in the finished product bin 501, the main controller 8 closes the third control valve 4022 and starts the electric pushing cylinder 502, and the electric pushing cylinder 502 drives the finished product bin 501 to slide away from the lower part of the grinding bin 402. The whole process, cereal is dried, is shaken the sieve, grinds and the unloading process and all accomplishes voluntarily, has saved the manpower, and has improved the grinding machining efficiency of cereal.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
