A heating element includes a filament that conducts electricity. In some embodiments, the filament is encapsulated in a silicon nitride cover. The heating element provides a heating zone located relatively closer to the tip of the heating element and relatively further from a connection where electrical leads connect to the filament.

Examples are disclosed herein that relate to a cooking system having multiple heating elements for heating a cooking surface. One example provides a cooking system, comprising a continuous cooking surface comprising a plurality of individually controllable heating zones, and for each heating zone, a temperature sensor configured to detect a temperature for the heating zone separately from the temperatures of other heating zones, and a heating element disposed beneath the heating zone and configured to provide heat to the heating zone. The cooking system further comprises a controller configured to individually control the heating element of each heating zone.

An oven includes a plurality of walls, a fan, and a heating element. The plurality of walls defines an internal cavity in which food may be placed for cooking. A first of the plurality of walls defines a plurality of orifices that establishes fluid communication between the internal cavity and a fluid path. The fan is configured to direct air from the fluid path, through the plurality of orifices, and into the internal cavity. The heating element is disposed on the first of the plurality of walls and adjacent to the plurality of orifices. The heating element is configured to heat the air being directed from the fluid path, through the plurality of orifices, and into the internal cavity.

Systems and methods to improve an industrial heater are disclosed. The heater comprises a horizontal cylinder oriented parallel to the ground and may encase an interior recess running the length of the heater. The heater may be divided into a plurality of sections or zones. One or more mid-rings may support the structure of the heater, and may be disposed at the intersections of adjacent sections or zones. A plurality of interior boards and/or insulation layers may line the interior façade, and may be configured to overlap each other and/or interlock together. The interlocking structure may be absent of any gap or space to prevent heat loss from the interior recess. One or more heat strips may be configured in a sinusoidal pattern. The strips may be mirrored on the opposite side of the interior recess, and may be configured to elongate in the direction opposite of gravity.

An oven system to heat a moving item includes a conveyor capable of moving at more than one speed along a path of movement; a heat source positioned along the path of movement; a baseline heating profile for heating the moving item at a constant velocity; a sensor to detect energy available for the heat source at a particular moment or over a period of time; and a system to dynamically modify, based on the energy available, the baseline heating profile into a modified heating profile including a variable conveyance speed, where, when the moving item exits the oven system, the energy supplied by the heat source to the moving item equals the energy to be supplied per the baseline heating profile.

A heating element can be moved by a machine, such as a machine including a fan, an actuator, or a conveyor. The heating element can be attached to or embedded in a fan or an actuator. Or, the heating element can be attached to or embedded in a conveyor belt of a conveyor. A combination of a heating element and a mover machine can be further combined with a heat radiating wall. The heating element and the machine can be arranged behind the wall. And, when the heating element and the machine are powered on, the heating element converts electrical energy into heat, which increases the temperature of the wall, and the machine moves the heating element to be next to different areas of the wall. This allows for heat to be distributed more evenly to the wall than it would be if the heating element did not move.
