Abstract

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.

Dependent claims

An apparatus for producing a surface-worked granular product, comprising

a cylindrical retainer having a multiplicity of apertures and a multiplicity of retaining sites for temporarily retaining each granule of granular material circling and traveling along the inner surface of the cylindrical retainer,
a rotary working device which is installed to a rotary shaft extending along the central axis of the cylindrical retainer and has a working protrusion protruding from the outer surface of the working device for removing foreign substances and surface-working the granular material so as to form a rough surface by contacting with the granular material,
a raw material supply site for supplying raw granular material to the cylindrical retainer,
a product takeout site for taking out a surface-worked granular product from the cylindrical retainer, and
an occurring dust discharge site for discharging, by suction, occurring dust from upper portion of the cylindrical retainer through the apertures causing to float the granular material.
