By adjusting the speed at which the vibrator vibrates vertically toward the end by adjusting the transfer amount of the vibration conveyor type drying device 2, it is possible to perform drying in an optimum state. Alternatively, only the perforated plate 28 may be vibrated.

[0011]

[Operation] Next, the operation will be described. The motor 11 is energized to rotate the rotating shaft 9 in the forward direction via the drive pulley 12, the belt 13, and the passive pulley 10 to rotate the agitator 16 in the normal direction. At the same time, the motor 8 is energized to rotate the coating drum 1 by the rollers 6 and 7. Rotate forward. Both the stirring body 16 and the coating drum 1 rotate normally, but the stirring body 16 rotates slightly faster than the coating drum 1. Further, the variable speed motor 33 is energized, and the entire vibration conveyor type drying device 2 (or only the perforated plate 28) is obliquely vertically vibrated toward the terminal end via the eccentric wheel 31, and the blower 29 is rotated to cause the heater 30 to rotate. Energize to generate hot air and vibrate conveyor dryer 2
Supply to. The hot air supplied to the vibration conveyor type drying device 2 tries to blow up from the supply cylinder 26, but the discharge port 2
4 has a wind stop valve 25, so it does not blow up.

When rice grains are supplied from the hopper 18 in this state, the rice grains are fed by the feeding valve 21 rotated by the motor 22 by a predetermined amount, fed into the coating drum 1 through the feed port 19 and agitated by the agitator 16. . At the same time, since an appropriate amount of the coating material is sprayed from the coating material spray nozzle 20, the rice grains are agitated by the agitator 16 while being sprayed with the coating material and gradually move to the discharge part 5, so that the coating material is evenly attached. Then, it is discharged from the discharge port 24 and reaches the inside of the vibration conveyor type drying device 2. A variable speed motor 3 in the vibration conveyor type drying device 2
The perforated plate 28 vibrated by the eccentric wheel 31 rotating at 3 dries while being transported, and reaches the end and is taken out from the take-out port 34. However, since the variable speed motor 33 can adjust the speed of the number of revolutions of the motor, The rotation of the wheel 31 is adjusted to adjust the vibration of the vibrating conveyor-type drying device 2, and the speed of taking out to the outlet 34 is adjusted to adjust the dryness.

[0013]

The present invention comprises a coating drum 1 and a vibrating conveyor type drying device 2 connected to the coating drum 1. The coating drum 1 is a horizontal cylinder rotary type, one end of which is a supply unit 4 and the other end of which is a discharge unit. 5, a rotary shaft 9 having a plurality of agitating members 16 mounted on the outer periphery at a predetermined interval is provided at the center of the coating drum 1, and the supply unit 4 of the coating drum 1 has an internal drum. In the apparatus provided with the coating material spraying nozzle 20 for spraying toward, the vibrating conveyor type drying device 2 is a horizontal tube type and is provided with substantially horizontal perforated plates 28 in the upper and lower middle portions thereof.
8 is a rice grain coating device configured to vibrate up and down obliquely toward the outlet 34 at the end through the eccentric wheel 31 rotated by the variable speed motor 33, which is different from the conventional known spray. Since the stirrer 16 is configured to spray the rice grains that are in a stirring state, the coating can be performed uniformly, and the supply unit 4 is provided with the coating material spraying nozzle 20 that sprays into the drum. Can be coated well because it is surrounded by the atmosphere of the coating material. Further, since the perforated plate 28 is configured so as to vibrate obliquely up and down toward the outlet 34 at the end via the eccentric wheel 31 rotated by the variable speed motor 33, the best drying is possible. Further, according to the present invention, since the perforated plate 28 is a rice grain coating device which vibrates together with the vibrating conveyor type drying device 2, the perforated plate 28 can be easily vibrated.
