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.

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.

Pressure assist feature for pressure fryer

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.

An apparatus and method for determining a load size of a food product in a cooking device is described. The apparatus includes a carrier assembly for receiving a food product; a cooking vessel containing a cooking medium, for receiving the carrier assembly; a lid assembly for raising and lowering the carrier assembly; a weight-bearing portion for supporting the lid assembly and the carrier assembly; a load sensor placed on the weight-bearing portion so as to measure a weight of the carrier assembly, the load sensor providing an output signal; and a control device for receiving the output signal and determining cooking parameters for the food product. A method for determining a load size of a food product in a cooking device includes the following steps: weighing a carrier assembly when the carrier assembly is empty to determine an empty carrier weight; weighing the carrier assembly when the carrier assembly contains a food product to determine a loaded carrier weight; determining a differential between the empty carrier weight and the loaded carrier weight, resulting in a food product load; reporting the food product load; and modifying cooking parameters responsive to the food product load.

Apparatus and method for determining load size of food product

A cooking medium management system and method from manipulating a cooking medium during cooking operations. The system has a controller generating a lock-out signal and a transfer signal, and selectively generating one control signal selected from the group consisting of a discard signal, a fresh fill signal, a drain signal, a filtration signal, and a polish signal. The system also has a cooking medium transfer pump and a transfer conduit for transferring the cooking medium to and from a frypot, wherein the transfer pump activates in response to the transfer signal. The system further includes a lock-out device, which receives the lock-out signal and disables a fryer heater. Moreover, this system includes a discard device, which receives the discard signal and includes the frypot, the drain pan, a drain valve and a cooking medium drain. The frypot and the drain pan are placed in communication with the transfer conduit via the drain valve. Subsequently, the drain pan and the cooking medium drain are placed in communication with the transfer conduit to discard used cooking medium. In addition, the system includes a fresh fill device, which receives the fresh fill signal and includes the frypot and a cooking medium source. The frypot and the cooking medium source are placed in communication with the transfer conduit to fill the frypot with fresh shortening. The system also includes a filtration device, which receives the filtration signal and places the frypot and drain pan in communication with the transfer conduit to filter the cooking medium. Finally, the system includes a polish device, which receives the polish signal and places the frypot and the drain pan in communication with the transfer conduit in response to the polish signal, fills the frypot to a predetermined level, and places the frypot and the drain pan in communication with the transfer conduit for a predetermined time period, and places the frypot and the drain pan out of communication with the transfer conduit after completion of the predetermined time period.

Cooking medium management system

The invention relates to a cooking device including a vessel for heating a cooking substance. The cooking substance is divided between a heating zone, a transition zone, and a cold zone. A first heating element is used to heat the cooking substance in the heating zone, and a transition zone heating device is used to heat the cooking substance in the transition zone. The transition zone heating device may be a pump for introducing a mixing medium into the cooking substance in the transition zone whereby the cooking substance in the heating zone mixes with the cooking substance in the transition zone. The mixing medium may be air, whereby the cooking substance in the heating zone is turbulently mixed with the cooking substance in the transition zone. The mixing medium also may be a portion of the cooking substance withdrawn by the pump from the transition zone and then reintroduced to the transition zone, thereby creating turbulence in the transition zone. The transition zone heating device may also be a second heating element. A method for operating a cooking device includes a vessel for heating a cooking substance. The cooking substance is divided between a heating zone, a transition zone, and a cold zone. The method comprises the steps of heating the cooking substance in the heating zone to a predetermined temperature and mixing the cooking substance in the transition zone with the cooking substance in the heating zone, thereby creating turbulence within the cooking substance in the transition zone. The turbulence is created by introducing air into the cook substance in the transition zone or by withdrawing a portion of the cooking substance from the transition zone and reintroducing the portion to the transition zone.
