Abstract
Abstract AN APPARATUS FOR CONTINUOUSLY DELIVERING A UNIFORM SUPPLY GRANULAR MATERIAL, E.G. GRANULAR TABLE SALT, FOR APPLICATION UPON THE SURFACE OF EDIBLE PRODUCTS, E.G. POTATO CHIPS, MOVING BENEATH THE APPLICATION APPARATUS. THE APPLICATOR IS CHARACTERIZED BY A CONTINUOUSLY ROTATING DRUM HAVING AN ANNULAR GROOVE WHICH RECEIVES GRANULAR MATERIAL FROM A FEED TUBE PROJECTING INTO THE GROOVE. AN ADJUSTABLE FLOW CONTROL GATE PROJECTS RADIALLY INTO THE GROOVE. A FLOW CONTROL SLOT IS FORMED BETWEEN THE GATE AND THE GROOVE WHICH MAY BE VARIED IN WIDTH TO CONTROL THE FLOW OF GRANULES AS THE DRUM ROTATES. GRANULES FLOWING THROUGH THE SLOT ARE CONVEYED IN THE GROOVE TO A CHUTE WHERE THEY FALL BY GRAVITY UNTIL STRIKING A SERIES OF BAFFLES WHEREUPON THEY ARE DEPOSITED UPON THE SURFACE OF THE PRODUCT BEING COATED.
