Abstract:
An apparatus for sprinkling powder material onto food products, the food products being placed on an upper surface of a conveyor, the apparatus comprising:hopper means, located above said conveyor, for holding powder material in a space defined by inner walls of said hopper means, said inner walls including a first substantially vertical wall, a second vertical wall opposite said first vertical wall, and curved portions located under said vertical walls, said hopper means having an exit opening provided on a bottom thereof;a rotating member, rotatably mounted within said hopper means, said rotating member having a rotation surface wherein recesses are provided thereon for receiving the powder material and wherein said rotation surface rotates in a direction toward an area under said first vertical wall of said inner walls as viewed from said first vertical wall;a narrow passageway provided between said rotation surface of said rotating member and said inner walls of said hopper means for receiving the powder material, said narrow passageway having a width that is narrower at the area near said exit opening than at the area above said curved portion of said inner walls of said hopper means, so that said narrow passageway presses the powder material against said rotation surface of said rotating member in said hopper means;a movable plate slidably supported on said inner wall of said hopper means above said narrow passageway, wherein said movable plate stirs the powder material within said hopper means and feeds the powder material into said narrow passageway by its sliding movement; andmeans for wiping the compressed powder material from said rotation surface of said rotating member adjacent said exit opening of said hopper means, thereby causing the wiped powder material to exit through said exit opening.
