Abstract
Abstract An apparatus and process for continuously producing a co-extruded wrapped food product is disclosed. The apparatus includes a double nozzle extruder member having inner and outer tubular barrels arranged with the inner barrel being positioned centrally within the outer barrel. First and second hoppers are adapted to supply a filling food material and a moldable food material to their respective barrels. Feeding means continuously move the two food materials from each of their hoppers through the barrels to form a filled ribbon of food material. Means is included for continuously shaping, cutting and sealing the ribbon to form the wrapped food product in a single step and without any waste. The shaping, cutting and sealing means is adapted to receive the ribbon of food material and continuously produce the final wrapped food product. The wrapped food product is then either continuously frozen or continuously cooked to the desired level in a cooker which completes the continuous process for partially or completely cooking the wrapped food product.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
270 words
An apparatus for continuously producing a wrapped food product, comprising a filling food material surrounded by a moldable food material, said apparatus comprising: a double barrel extruder member having an inner elongated tubular barrel arranged substantially centrally within an elongated surrounding outer tubular barrel; a first hopper adapted to supply said filling food material to said inner tubular barrel; a second hopper adapted to supply said moldable food material to said surrounding outer tubular barrel; feeding means for continuously moving said food materials from each of said hoppers through each of said tubes respectively to an end of each of said tubular barrels to form a filled ribbon of food material; means for continuously shaping, cutting and sealing said ribbon to form said wrapped food product, said shaping, cutting and sealing means being positioned adjacent said feeding means, and adapted to receive said ribbon of food material and continuously shape, cut and seal to form said wrapped food product; and cooking means operatively connected to a moving means operatively associated with said shaping means, said cooking means comprising, top, bottom and side wall members defining a cooking chamber housing a cooking solution, an elongated entrance tube extending through said top wall member and into said chamber, said elongated entrance tube being adapted to receive a wrapped food product from said moving means and directing it to a bottom section of said chamber, means for creating turbulence in said bottom section of said chamber, means for introducing a heated cooking solution into said chamber, and means for directing a cooked wrapped food product out of a top section of said chamber.
Claim 2
Independent Claim
270 words
An apparatus for continuously producing a wrapped food product, comprising a filling food material surrounded by a moldable food material, said apparatus comprising: a double barrel extruder member having an inner elongated tubular barrel arranged substantially centrally within an elongated surrounding outer tubular barrel; a first hopper adapted to supply said filling food material to said inner tubular barrel; a second hopper adapted to supply said moldable food material to said surrounding outer tubular barrel; feeding means for continuously moving said food materials from each of said hoppers through each of said tubes respectively to an end of each of said tubular barrels to form a filled ribbon of food material; means for continuously shaping, cutting and sealing said ribbon to form said wrapped food product, said shaping, cutting and sealing means being positioned adjacent said feeding means, and adapted to receive said ribbon of food material and continuously shape, cut and seal to form said wrapped food product; and cooking means operatively connected to a moving means operatively associated with said shaping means, said cooking means comprising, top, bottom and side wall members defining a cooking chamber housing a cooking solution, an elongated entrance tube extending through said top wall member and into said chamber, said elongated entrance tube being adapted to receive a wrapped food product from said moving means and directing it to a bottom section of said chamber, means for creating turbulence in said bottom section of said chamber, means for introducing a heated cooking solution into said chamber, and means for directing a cooked wrapped food product out of a top section of said chamber.
Claim 3
Dependent Claim
