"Function" The raw material beans are first subjected to a coarse selecting machine to remove foreign matters or crushed particles which are not suitable for polishing, and the coarsely selected beans are continuously discharged.

The beans discharged from the roughing machine in the roughing process are supplied to a supply hopper of the beans polishing machine in the next polishing process.

The beans in the supply hopper are supplied from the supply section to the lower part of the polishing cylinder in the vertically elongated outer shell and are fried by the lifting spiral which is rotationally driven by the drive motor, and the beans are also rotationally driven in the relative direction by the drive motor. The beans that have risen while being agitated in the gap between the polishing cylinder and the lifted-up spiral, are polished by the friction of the abrasive, and the beans that have passed through are discharged from the discharge port at the upper end of the polishing cylinder.

The beans are first rubbed by the abrasive in the lower polishing stage while frying, and then gradually ascended and rubbed by the abrasive in the upper polishing stage. The polishing material of each polishing stage is set appropriately according to the condition of the beans to be processed.When the raw material beans are in poor condition, the polishing material of the lower polishing stage is set to be hard or rough, and the polishing material of the upper polishing stage.
