Description

[Detailed Description of the Invention] This invention provides a method for making grains such as rice and wheat grains,
This is a vertical type grain sorter that separates large-diameter grains and small-diameter waste grains while moving the grains upward in a cylindrical sorting net installed vertically inside the shell.

In a vertical granule sorter, the upper surface of the sparsal material that fits into the cylindrical sorting net and performs the granule lifting action.

It is conceivable to improve the sorting rate by making the dynamic friction resistance larger than that of a flat metal plate, thereby reducing the grain lifting efficiency and increasing the chances of the grains coming into sliding contact with the inner circumference of the sorting net. Invention based on this idea.

The present applicant has already appeared as Tokuton Sho 57-37 Otsu Tata No. by carrying out the nuclear invention.

The selection rate has improved dramatically.

However, since the dynamic frictional resistance of one surface of the spiral blade is made uniform from the center toward the outside, as the amount of grains processed increases, the sorting rate is rapidly decreased.

This invention is designed to reduce fluctuations in the sorting rate depending on the amount of processing, and is configured in a first-order manner. That is, in a vertical grain sorter in which a cylindrical sorting net +11 and a shaft (2) with spiral wings for lifting grains fitted in this sorting net [11] are installed upright so as to rotate concentrically with each other, the spiral Wing 13) Grain lifting efficiency on the upper surface is determined by at least the sorting holes (4) of the sorting net body fil.
) The position corresponding to the drilling range was changed so that it became better as it went outward from the rotation center side.

The present invention achieves the first technical effect with the above configuration. In other words, one sorting net (11t) is supplied by a claw, that is, if the throughput is small, one moss, and a spiral blade i31 is used.
Crabs subjected to grain lifting action on the outer periphery of the upper surface. At that time, even if good grain lifting action is received, the grains slide into contact with the inner peripheral surface of the 1 sorting net (1) and are sorted due to the small throughput. There are many opportunities to be sorted through hole (A), and the sorting rate is good. In addition, when the amount of crabs to be processed is large, depending on the amount of crabs to be processed, the spiral blade; Since the inner circumferential surface of the body is sorted through the sorting hole (4), the sorting rate does not drop much compared to the case where the throughput is small (8). In this way, it has become possible to maintain a nearly constant sorting rate even when the throughput fluctuates.

Next, the configuration of an embodiment of the present invention will be described with reference to one drawing.

The overall structure of the vertical granule sorter is as shown in Figure 1, with a large number of sorting holes (4) inside a square cylindrical shell (5).
