A device for forming a stuffed proteinaceous patty, the device comprising: a) a first proteinaceous food product dispensing hopper providing a first and a second stream of proteinaceous food product; b) an upper conveyor belt traveling in a select direction at a select speed for receiving said first stream of first proteinaceous food product; c) a lower conveyor belt for receiving said second stream of first proteinaceous food product travelling parallel to, in the same select direction, and at the same select speed of the upper conveyor; d) a food grade particulate dispensing hopper, said food grade particulate hopper being in dispensing communication with a variable speed conveyor belt with a first end and a second end where the first end is positioned to receive the food grade particulate dispensed from the food grade particulate dispensing hopper and the second end is positioned between said upper and lower conveyors (58U, 58L), to discharge the food grade particulate directly onto said second stream of said first proteinacous food product; and wherein the food grade particulate hopper includes a metering volumetric cleated dispensing cylinder, a first low level sensor and a second high level sensor for detecting the level of food grade particulate in the hopper to maintain a substantially constant weight pressure thereof on the volumetric cleated dispensing cylinder, said sensors being connected to a hopper volume control system including an ingredient conduit, an in-line vacuum suction module, a solenoid and compressed air source to force to the ingredients through the conduit to the hopper when the food grade particulate in the hopper is detected at level below a set minimum, the device further comprising e) a patty forming device for receiving said first stream of said first proteinaceous food product and said second stream of said proteinaceous food product bearing said food grade particulate where said first and second streams converge and are formed into an integrated patty containing said food grade particulate. a) a first proteinaceous food product dispensing hopper providing a first and a second stream of proteinaceous food product; b) an upper conveyor belt traveling in a select direction at a select speed for receiving said first stream of first proteinaceous food product; c) a lower conveyor belt for receiving said second stream of first proteinaceous food product travelling parallel to, in the same select direction, and at the same select speed of the upper conveyor; d) a food grade particulate dispensing hopper, said food grade particulate hopper being in dispensing communication with a variable speed conveyor belt with a first end and a second end where the first end is positioned to receive the food grade particulate dispensed from the food grade particulate dispensing hopper and the second end is positioned between said upper and lower conveyors (58U, 58L), to discharge the food grade particulate directly onto said second stream of said first proteinacous food product; and wherein the food grade particulate hopper includes a metering volumetric cleated dispensing cylinder, a first low level sensor and a second high level sensor for detecting the level of food grade particulate in the hopper to maintain a substantially constant weight pressure thereof on the volumetric cleated dispensing cylinder, said sensors being connected to a hopper volume control system including an ingredient conduit, an in-line vacuum suction module, a solenoid and compressed air source to force to the ingredients through the conduit to the hopper when the food grade particulate in the hopper is detected at level below a set minimum, the device further comprising e) a patty forming device for receiving said first stream of said first proteinaceous food product and said second stream of said proteinaceous food product bearing said food grade particulate where said first and second streams converge and are formed into an integrated patty containing said food grade particulate.
