[0008]

The operation of the present invention is as follows.

Brown rice or white rice to be weighed falls into a discharge case body constituting a shutter device below the storage tank, and is read into a flexible container bag placed on a platform scale. At that time, a small amount of brown rice or white rice to be weighed flows into the discharge case body from the attached sample intake section.

Further, the sample extract constituting the sample extractor which is a main part of the present invention is driven by a motor. And the predetermined amount of extraction by the sample extract,
For example, it can be changed to about 30 g, 50 g, 100 g, or the like. In addition, by using the timer at two locations, it is possible to extract a sample more evenly within the supply time.

[0011] When the above-mentioned sample extract is rotated at a set time for extracting a predetermined amount of sample within a preset time, the partition formed by the extractor stores the sample extract. A predetermined amount of brown rice or white rice is stored in the unit.

[0012] As described above, brown rice, white rice, or the like stored in the storage unit is discharged to the sample outlet by rotating the sample extract at a predetermined speed. The discharged sample is sent to a sample packing machine or the like.

The sample extract of the present invention is designed so that a large amount of brown rice or the like falling in the discharge case body in large quantities is taken into the sample intake section, and the taken-in partial brown rice or the like is dropped into the storage section of the sample extract. Therefore, when stored in the storage unit from the sample intake unit, brown rice or the like does not scatter at all. This is a point that is significantly different from the above-described conventional one.
