However, in the sorting device, if the airflow is simply diverted, rice, rice husks and straw debris will flow forever along with the airflow, and the sorting efficiency will be very poor. However, it is necessary to arrange a large number of plates, which not only increases the size of the sorting apparatus and increases the cost, but also is inconvenient when cleaning the sorting apparatus.

Further, in the conventional starter device, unnecessary operation may be performed, operation may malfunction, wasteful energy may be used, and the cost may be increased or smooth operation may be hindered.

In view of the above-mentioned circumstances, the present invention provides a de-sorting device that can be downsized and an efficient paddy because the sorting device exerts an efficient sorting function with an extremely small number of plate arrangements. The purpose of the present invention is to provide a starter for shaving / rice polishing.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is configured as follows.

1) In a fully automatic de-sorting device having a sorting device provided between the desorption chamber and the suction chamber, an eddy current sorting unit was provided in the sorting device, and the vortex flow sorting unit was formed in a downward opening type.

2) In 1) above, a downstream sorting path portion in which an obliquely upward airflow is generated is provided below the eddy current sorting portion, and a rectifying blade is provided above the lower end port of the downstream sorting path portion.
3) In a fully automatic de-sorting device with a sorting device provided between the de-chamber and the suction chamber, the sorting device and the intake chamber by the fan are connected by a communication hose, and a wind force adjusting plate is installed on the fan-side duct of the communication hose. It was provided with an inner collar on the suction adjustment mouth of the wind force adjusting plate.

4) The same switch has a built-in timer function, and the rice hulling function and rice polishing function can be activated, and the mode switching switch enables switching between single operation and simultaneous operation of rice hulling and rice polishing.

[Action]

Since the fully automatic descreening device is configured as described above, it operates as follows.

1) In the eddy current sorting unit, since the air flow temporarily stagnates, heavy rice falls in the meantime, and light rice husks, straw debris, etc. accompany the air flow, so that sorting is efficiently performed.

2) Since the airflow is suppressed by the flow straightening vanes above the downstream sorting path, rice drop is promoted at that portion, and the airflow is accelerated below, so that rice husks and straw debris are blown up, and sorting is performed. Is surely done.

3) Since the rice husks and the like hit the inner collar, it is possible to prevent the inconvenience that the rice husks and the like leak from the suction adjusting port.

4) Since it is possible to easily switch between single operation and simultaneous operation of hulling and rice polishing with one switch, malfunction is prevented,
Cost reduction has been established.
