A surface-worked granular product is produced by supplying raw granular material to a cylindrical retainer having apertures and retaining sites, floating the granular material by suctioning air from the cylindrical retainer, rotating a rotary working device installed in the cylindrical retainer, and contacting working protrusion protruding from the working device with the granular material to remove foreign substances and to perform surface-working of the granular material so as to form a rough surface without causing degeneration, denaturation or substantial removal of useful ingredients, wherein the surface-worked granular product has surface characteristics different from raw granular material.

The present invention is directed to setting an operation parameter of a grain milling machine appropriately according to the characteristics of grain targeted for processing. An operation aid apparatus for a grain milling facility including a grain milling machine and a color sorter includes a first acquisition portion configured to acquire first information regarding characteristics of grain that should be processed in the grain milling facility, and a second acquisition portion configured to acquire second information regarding an evaluation of a sorting result acquired by milling first grain by the grain milling machine and sorting them by the color sorter after that. The second information is associated with the first information regarding the first grain. The operation aid apparatus further includes a setting portion configured to determine an operation parameter for processing second grain by the grain milling machine based on the first information regarding the second grain that should be newly processed in the grain milling facility and the second information associated with the first information regarding the first grain.

A flexible polishing apparatus for granulated grains is provided. The flexible polishing apparatus includes a housing, a feeding device, at least one flexible polishing unit, a bran discharging device, and a rice outlet. The flexible polishing unit includes a radial gravity self-flow flexible polishing chamber. The feeding device, the flexible polishing chamber and the rice outlet are sequentially arranged from top to bottom along the gravity direction. The flexible polishing apparatus for granulated grains avoids the shear effect of granulated grains in the polishing chamber, improves the flexible friction effect, and greatly reduces the damage to rice in the polishing process while ensuring that rice bran is cleaned and the rice is polished, thereby improving the rate of polished rice and reducing energy consumption.
