PURPOSE:To obtain an efficient blending and grinding apparatus for coffee beans, etc., by providing a rotor with a given coveyer in a vessel whose upper part and a horizontal semicylindrical bottom is attached to the lower part of the vessel is formed into a square box and a blind plate and a metallic net can be exchanged with the cylinder at will. CONSTITUTION:When coffee beans, for example are put in the charging port 2 and the rotary shaft 5 is turned by a motor, and beans are completely raked up by sliding rotation on the inner surface of the cylinder 14 of the scraping blade 11 slightly inclined to the generatorix and the put successively into the aperture in the ribbon-type conveyers 6 and 7. The movement is repeated. Then, part of the coffee beans is sent little by little toward the left direction by the rotation of the large diameter ribbon-type conveyer 7 and at the same time partly sent toward the right direction by the rotation of the small diameter ribbon-type conveyer 6. In case where rice is cleaned, the horizontal cylinder 14 is exchanged with the metal net b. |
