Patent ID: 7153119

Claim:
An extruding apparatus using food materials including a filling material and a wrapping material to extrude and envelop the filling material with the wrapping material, the apparatus comprising: an internal cylinder for supplying the filling material; an external cylinder being concentrically arranged outside the internal cylinder, and defining an annular space for supplying the wrapping material between the external cylinder and the inner cylinder such that the cylinders extrude the materials in which the supplied wrapping material envelopes said filling material from said internal cylinder; a rotating member being arranged inside the external cylinder; at least one stirring member for stirring and fluidizing the wrapping material passing through the annular space, wherein the stirring member is mounted on the rotating member such that the stirring member is rotated or swung in the annular space; a driving mechanism being arranged outside the external cylinder to provide a force to drive the rotating member; a sealing section being sealed between the rotating member and the driving mechanism; a transmission mechanism for drivingly and detachably engaging the rotating member through the external cylinder and the sealing section so as to transmit the force of the driving mechanism to the rotating member; and a storage space section being installed near the sealing section for storing the wrapping material that has penetrated therein via the sealing section from the annular space through the rotating member to prevent further penetration of the wrapping material into the driving mechanism.
