A food grilling device includes a lower portion for holding food, an upper portion for trapping food between the upper and lower portions, and a sliding, adjustment mechanism. The upper portion is positioned over the lower portion and is movable relative to the lower portion. The sliding, adjustment mechanism is coupled between the lower portion and the upper portion and permits the upper portion to move forward, rearwardly, upwardly, and downwardly relative to the lower portion. The food grilling device has an open position and a closed position. In the open position, food is inserted between the lower and upper portions. In the closed position, food is trapped in the food grilling device by pressure or friction exerted on the food by the upper portion. Movement of the upper portion relative to the lower portion in a forward and rearward direction turns the food positioned between the upper and lower portions.

A thermal processing apparatus (20) includes a spiral conveyor system (22) configured into an ascending spiral stack (26). An air balance tunnel (40) includes a tunnel housing (76) positioned inside of a thermal processing chamber adjacent an outlet opening (36). A conveyor belt (24) travels through the housing on its way out of the processing chamber. An air pervious ejector assembly (78) is positioned within the housing at an elevation above the conveyor belt (24). An air pervious evacuation sheet (80) is located within the housing at a location beneath the conveyor belt (24). An air pervious cover assembly (150) is positioned over the conveyor belt (24) at a location just before the conveyor belt enters the air balance tunnel (40). The cover sheet (150) is connectable to the ejector assembly (78) so as to remove the ejector assembly from the tunnel housing (76) by manually moving the cover assembly (150).

A cooking device (1) for cooking foods on a barbecue includes a support frame provided with two longitudinal members (12) and at least one food-holding grill (10) pivoted between the longitudinal members (12). The cooking device (1) is provided with a control transmission formed by at least one sprocket (14, 305, 425) connected to the grill (10) and engaged with a chain (15, 302, 303, 424), the chain (15) being actuated by a motor (16) controlled by a timer (17) for automatically inverting the grill (10) around the corresponding axis of rotation (X). The control transmission is adapted to mechanically and periodically invert the grid (10), allowing a uniform cooking of the food.

A heat transfer system for cooking a food product is provided. The heat transfer system includes an enclosure, heat sources within the enclosure operate to output heat for a cooking process, at least one conveyor positioned relative to the cooking heat elements, and a warming assembly. The warming assembly is configured to receive at least one pan configured to store cooked food product. The warming assembly defines an controlled environment about the at least one pan. A blocking element defines an opening through the enclosure into the controlled environment of the warming assembly.

A forced hot air roller conveyor drying assembly is provided. It consists primarily of two parts; a roller conveyor for rolling cylindrical elongated food members while transporting them horizontally from one end of the conveyor to the other, and a hot air drying assembly for blowing hot air around the product as it is being rolled. The combined rolling of the product and the drying of the product helps ensure that the physical roundness of the food product remains nice and uniform while it is being uniformly dried. The forced hot air assembly may include a fan and heating elements, the fan directing warm air to the product rolling horizontally through the assembly and the roller conveyor may be comprised of a multiplicity of paired roller members driven by chain links, which chains are in turn driven by an axle engaging a drive sprocket.

Disclosed is a mesh heating system including: two or more electrodes configured to supply a current to the wire mesh heating element; a mesh heating element comprising filaments disposed between the two or more electrodes; and a tensioner to maintain the wire mesh heating element at tension along an axis of tension as the wire mesh heating element is heated, wherein some of the filaments of the mesh heating element are disposed to intersect the axis of tension at a non-orthogonal angle.

A rotisserie oven for cooking food, eg spatchcock chicken, comprises an oven enclosure (23), a solid fuel conveyor (2) for conveying a burning solid fuel (eg charcoal) bed through the oven enclosure, and a food conveyor (3) crossing the solid conveyor transversely within the oven enclosure. The charcoal is lit outside the oven enclosure by a gas burner (21) and high temperature combustion, eg at 250 C. to 450 C., is supported by a jet of hot air (c) injected by a hot air blower (19) into the oven enclosure. Hot combustion gas circulates within the enclosure and the speed of the solid fuel conveyor is controlled in response to the output signal of a thermocouple (17) to maintain a desired cooking temperature.

Systems and methods for cutting and cooking a substance are disclosed. Exemplary implementations may: convey, via a primary conveying subsystem, a layer of food substance along a conveyance path along which the layer of food substance is conveyed; cut, via a cutter, the layer of food substance into food pieces; apply, via a primary pressurized fluid outlet, primary pressurized fluid such that the food pieces are released from the cutter; heat, via the heating mechanism, a chamber; apply, via a secondary pressurized fluid outlet, secondary pressurized fluid so that the food pieces are held flat to the primary conveying substrate, and hold, via a secondary conveying subsystem, the layer of food substance flat between the primary conveying substrate and a secondary conveying substrate for at least a portion of the chamber.

A heat transfer device for thermal treatment of food items includes an enclosure defining an interior of the heat transfer device. A first and second driven conveyor systems are positioned within the enclosure. A first primary heater is arranged interior of the first chain conveyor belt. A first chain heater is arranged proximate to the first chain conveyor belt at a location of the first chain conveyor belt proximate to the opening. A second primary heater is arranged interior of the second chain conveyor belt. A second chain heater is arranged proximate to the second chain conveyor belt at a location of the second chain conveyor belt proximate to the opening.

The present invention discloses a movable type grill roaster. In the present invention, bucket depressions and a rod rolling part are provided in a chain. Accordingly, when grilling rods constituting a grill roasting plate are sequentially transferred via the chain, the grilling rods may be transferred while being rolled. The phenomenon in which meat adheres to the grilling rods is prevented. The sequentially supplied grilling rods are arranged at stable locations, and thus there is overcome the problem in which meat falls between the grilling rods constituting a grill roasting plate. When the grilling rods fall to a collection container, the falling grilling rods may be evenly distributed without being concentrated on any one point in the collection container via a fall guide piece. The convenience in use is improved during a grilling rod supply process, a meat roasting process, and a grilling rod collection process.
