Abstract: Systems and methods for delivering a cooking medium in a cooking apparatus are disclosed. A delivery system includes a rotary valve having a rotary inlet and a plurality of rotary outlets. The rotary inlet is configured to be in fluid communication with a source of cooking medium and the plurality of rotary outlets are configured to be in fluid communication with a corresponding plurality of receptacles. A rotary position sensor generates a signal, having continuous angular position resolution, based on an angular position of the rotary valve. A controller receives the signal generated by the rotary position sensor and selectively places the rotary inlet in fluid communication with one of the plurality of rotary outlets based on the signal generated by the rotary position sensor. The rotary position sensor may include a Hall-effect sensor that functions at elevated operating temperatures associated with the cooking medium.

Abstract: Systems and methods for adjusting the pressure in a cooking chamber of a pressure fryer. The pressure inside the cooking chamber is determined in response to detecting closure of a valve that vents the cooking chamber. The pressure in the chamber is compared to a predetermined pressure. If the pressure in the chamber is less than the predetermined pressure, a pressure assist system is activated. The pressure assist system includes an air pump and/or pressure source, and when activated, supplies a gas to the cooking chamber to increase the pressure in the cooking chamber. The pressure may be determined at a predetermined time after closure of the valve, and an amount of gas to be added to the cooking chamber determined based on a difference between the measured pressure and the predetermined pressure. Use of the pressure assist system allows for optimal cooking of batches of food of many sizes.

Abstract: A fryer apparatus and method of frying food products includes a cooking chamber, a heater disposed external to the cooking chamber, a fuel system disposed external to the cooking chamber, a blower configured to propel an airflow toward a heater, and a fuel injector configured to inject fuel into the airflow to create an air-fuel mixture. The fuel system is configured to deliver an air-fuel mixture to the heater. The heater is configured to ignite the air-fuel mixture to provide an external heating source for the cooking medium within cooking chamber. The temperature of the cooking medium is controlled by varying the speed of the airflow.
Abstract: A gas fryer and associated methods of cooking food products are disclosed. The gas fryer includes an infrared burner and a fry pot including an interior casing defining a cooking chamber, with the interior casing including a bottom wall and opposing sidewalls that extend upwardly from the bottom wall. The opposing sidewalls include lower, central, and upper sidewall panels that are angled from one another to define a tapered profile that narrows towards the bottom wall. The tapering of a well defined at a lower chamber portions of the cooking chamber allows for a shallow depth at this portion of the fry pot and easy visibility and access for cleaning. Furthermore, the opposing sidewalls and a rear end wall of the interior casing include heat exchange fins on an external surface.

Abstract: An automatic fryer apparatus and method of frying food products includes a cooking chamber, a heating mechanism disposed in the cooking chamber, and a pump disposed at an end of the cooking chamber to circulate cooking medium within the cooking chamber. Food product is added to the cooking chamber and flows along with the cooking medium in a flow direction. A controller controls a plurality of gates by individually actuating each gate. The controller stores data regarding predetermined time periods, which regulate when to raise and lower each gate. Food product moves downstream of each gate along a flow direction when each respective gate is raised. Food product is automatically transferred to a holding station when it reaches an outlet end of the cooking chamber.

Abstract: An automatic cooking medium level control system for a cooking apparatus, e.g., a fryer, may include a cooking vessel having a first temperature sensor at a first level of the cooking vessel and a second temperature sensor at a second level of the cooking vessel. A reservoir holding a cooking medium, such as cooking oil, may be in fluid communication with the cooking vessel. A controller may monitor temperature data from the first and second temperature sensors to determine whether the level of cooking oil in the cooking vessel has lowered. Upon determining that the cooking oil level has lowered, the controller may actuate a supply mechanism, such as a pump, which may be disposed on a fluid communication path between the reservoir and cooking vessel, which may enable the introduction of cooking medium from the reservoir to the to the cooking vessel.

Abstract: A diverter, and a cooking chamber and cooking apparatus including the diverter, is capable of diffusing liquids, semi-solid substances, and the like. The diverter includes a diverter plate and an orifice that projects from a surface of the diverter plate. The orifice has an open sidewall portion. The diverter further includes a recessed portion formed in the diverter plate, extending from the orifice, and a bumper portion that projects from a surface of the recessed portion and is disposed proximate to the orifice. The cooking chamber includes a heating element, a wall, an inlet port formed in the wall, and a cooking chamber fitting disposed adjacent to the inlet port. The cooking apparatus includes a cooking chamber, a filter pan, a filter pump, and an inlet port formed in a wall of the cooking chamber.
Abstract: A cooking apparatus comprises a heated compartment to warm cooking media that may be packaged in metal containers or the like. The heater system includes at least one heater disposed at a location to heat the bottom of the unused cooking medium container. The heater system may also include at least one heater disposed at a location to heat at least one side of the unused cooking medium container. A cooking apparatus comprises at least one supply reservoir, a fluid motive device, various enclosed cooking medium conductors or lines, a three-way valve that introduces air for purging the lines, and a cooking medium receiving system.
Abstract: A fryer apparatus includes a selectively closeable frypot to alternate a mechanism of operation between an open frying platform and a pressure frying platform. The selectively closeable frypot includes a cover with a locking mechanism disposed within the cover that is actuated by rotation of a handle such that the footprint of the selectively closeable frypot may be sized comparable with a typical open frypot to accommodate space constraints of limited service restaurants. The fryer apparatus may also include a pressure assist feature so that the selectively closeable frypot efficiently reaches a desired pressure for smaller batches of food product when used as a pressure frying platform.

Abstract: Methods and systems disclosed herein may be methods for rapidly increasing pressure in a pressure fryer cooking vessel during a cooking cycle. Such methods and systems may comprise determining whether a pressure output in the cooking vessel is closed. Such methods and system may also include determining a pressure of the cooking vessel, comparing the pressure of the cooking vessel to a predetermined optimal pressure to determine whether the pressure of the cooking vessel is less than the optimal pressure, and activating a filter pump configured to supply air from a drain pan into the cooking vessel in response to determining that the pressure output is closed and the pressure of the cooking vessel is less than the optimal pressure. Such methods and systems may further include deactivating the filter pump when the pressure within the cooking vessel is equal to or greater than the optimal pressure.
