APPARATUS FOR ENCRUSTING A FILLING MATERIAL

摘要

An apparatus for encrusting a filling material is provided. The apparat us includes a screw-transferring apparatus to transfer a filling material and encrusting material, and vane pumps to transfer the respective filling and encrusting materials to a combining nozzle. The combining nozzle combines th e crust that is supplied by the vane pump for crusts out of the filling materi al that is supplied by the vane pump for filling materials. Each screw-transferring apparatus includes horizontal screws. Each vane pump has a vertical rotating shaft. The end of each screw is free and is positioned at the inlet of each vane pump. At the inlet of each vane pump a food-guide plane is formed. That plan e is tangent to a trajectory of the outer edge of the vane of the vane pump. T he trajectory forms a circle that has the biggest diameter among all of the trajectories defined by the outer edges of the vanes when the vanes rotate.
