Abstract:

An apparatus to mix, extrude, shape, and cut an outer layer of viscous material about the core of another material, especially for preparing fresh ravioli, dumpling and similar pastry in kitchen. The apparatus includes two co-centric containers for holding materials, a mixing assembly for preparing the materials, an extrusion system wrapping core material inside the viscous outer layer, and a shaping and cutting assembly to form desired food units whether its ravioli, dumplings or other shapes. The container for core materials is removable and enclosed inside the container for outer layer materials. The mixing assembly for both core materials and outer layer materials comprises of a plurality of mixing and scraping blades attached to the spinning cylinder which is mounted in between outer container and inner container and to a centrally located tube inside the inner container, the centrally located tube is mounted on an inner lid which is securely caped on the spinning cylinder. And an extrusion system comprising of extrusion screw and dies, is mounted under the bottom of the outer container, through which contents of the outer container are extruded into desired tube-shaped outer layer and core materials are fed in a shape of continuous cylindrical link inside the outer layer before they are fed into the cutting roller. The shaping and cutting assembly comprises of two rollers where at least one roller is engraved for the desired shape and cut of food units. A single drive means rotates a main shaft that in turn drives rollers, turns spinning cylinder and the attached mixing and scraping blades, and turns extrusion screw. The extrusion screw, dies, the spinning cylinder and the inner container for core materials are removable from the apparatus for easy cleaning.
