Abstract: Methods for adjusting the pressure in a cooking chamber of a pressure fryer are provided. 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.

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: 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.

Abstract: A fryer apparatus is disclosed herein for rapidly increasing pressure in a pressure fryer cooking chamber during a cooking cycle. Such fryer apparatus may determine whether a pressure output in the cooking chamber is closed. The fryer apparatus also determines a pressure of the cooking chamber, compares the pressure of the cooking chamber to a predetermined optimal pressure to determine whether the pressure of the cooking chamber is less than the optimal pressure, and activates a filter pump that supplies air from a drain pan into the cooking chamber in response to determining that the pressure output is closed and the pressure of the cooking chamber is less than the optimal pressure. The fryer apparatus further deactivates the filter pump when the pressure within the cooking chamber is equal to or greater than the optimal pressure.

Abstract: A fryer apparatus includes a cooking chamber, at least one heating element in the cooking chamber, a filter pan that filters cooking medium from the cooking chamber, a drain valve that controls flow of cooking medium from the cooking chamber, and a filter pump that pumps filtered cooking medium from the filter pan to the cooking chamber. Inlet orifices are disposed in the cooking chamber, and selectively eject filtered cooking medium into the cooking chamber. A controller controls the drain valve to adjust the rate of flow from the cooking chamber, and selectively activates at least inlet orifice of the plurality of inlet orifices to eject filtered cooking medium into the cooking chamber. The controller is configured to control the drain valve and the selective activation of the at least one inlet orifice to maintain a substantially constant level of cooking medium in the cooking chamber throughout a filtering operation.

Abstract: An automatic filtering system for filtering a cooking medium in a fryer, includes a frypot; a filter manifold having removable filter; a pump, that supplies cooking medium from the filter manifold to the frypot; a pressure sensor that senses a pressure of the cooking medium supplied by the pump; and a controlling mechanism that controls an operation of the pump in response to the sensed pressure data. The control mechanism halts the operation of the pump after sensing a drop in the pressure of the cooking medium pressure that is greater than or equal to a predetermined pressure drop threshold. The systems and methods of the invention provide automatic filtering that may reduce or eliminate an incorrect refilling operation after the filtering of cooking medium, so that the filtering process may be performed correctly each time.
