Here, the first motor 513 is axially connected to the first gear 512, the first gear 512 is gear-connected to the first gear 511 formed on the outer circumference of the grain storage container (100). The controller 530 controls the rotation of the first motor 513. The controller 530 rotates the shaft of the first motor 513 at a constant rotation speed.

By the operation of the second rotating part 520, the screw rod 160 is rotated at 60 RPM per minute. Here, the second motor 523 is axially connected to the second gear 522, the second gear 522 is gear-connected to the second gear 521 formed on the outer periphery of the screw rod 160. The controller 530 controls the rotation operation of the second motor 523. The controller 530 rotates the shaft of the second motor 523 at a constant rotation speed.

The controller 530 determines whether the rotation time of the grain storage container 100 and the screw rod 160 through the first and second rotation parts 510 and 520 reaches a preset set time.

When the rotation time reaches the set time, the controller 530 opens the drain valve 620.

Therefore, the water supplied to the inside of the grain storage container 100 and discharged to the outer cylinder is discharged to the outside of the main body 800 through the water drain 610.

Subsequently, the controller 530 determines whether draining is completed.

A water flow sensor (not shown) may be further installed in the water drain pipe 621 connected to the water drain port 620.

The flow sensor measures the flow rate of the water flowing in the water drain pipe 621 and transmits it to the controller 530.

When the supply amount of water reaches a predetermined set amount, the controller 530 operates the vacuum pump 340.

Here, a vacuum suction force is formed in the upper discharge pipe 310, the first and second extension pipes 320 and 330, and the connection pipe 380.

Accordingly, the washing is completed and the grain stored in the grain storage container 100 is sucked through the lower end of the upper discharge pipe 310 to the outside along the connecting pipe 380, the first extension pipe 320, the second extension pipe 330. Discharged.

At this time, the grains discharged along the second extension tube 330 collides with the grain moisture removing protrusions 350 installed at a plurality of inner circumferences of the second extension tube 330, and thus moisture is easily removed. The grain container 700 is discharged.

Subsequently, the controller 530 determines whether grain discharge is completed.

The grain detection sensor 370 installed at the lower end of the second extension tube 330 may detect the grain discharged to the second extension tube 330 and transmit it to the controller 530.

Therefore, the controller 530 determines whether grain discharge is completed according to the detection signal transmitted from the grain detection sensor 370.

When the discharge of grain is completed, the controller 530 stops the operation of the vacuum pump 340.

The control unit 340 generates an alarm for notifying the end of washing using the second alarm generator 920.
