A robotic kitchen system for preparing food items in combination with at least one kitchen appliance such as a fryer comprises an automated bin assembly, a robotic arm, and a basket held by the robotic arm. The automated bin assembly comprises at least one automated bin for holding the food items. A camera or sensor array collects image data of the food items in the bin(s). A central processor is operable to compute and provide directions to the first robotic arm and automated bin assembly based on the image data and stored data to (a) move the robotic arm to the bin; (b) actuate the bin to drop the food items from the bin into the basket; (c) and to move the basket into the fryer all without human interaction. Related methods are also described.

An anti-oxidation frying device includes a frying vessel having an electrically conductive body configured to heat cooking oil carried therein by a heating unit. A removable basket, also formed of electrically conductive material, is configured to be carried within the frying vessel to enable the cooking of food in the heated oil. A rectification circuit is coupled to the heating unit, the body of the frying vessel, and the basket. During operation the rectification circuit converts AC power from an external power source into a rippled, rectified AC current signal that is supplied to the heating unit, body of the frying vessel, and the basket, so as to create a reducing environment of available electrons for absorption by the cooking oil and food as it is prepared, thus extending the life of the cooking oil.

Disclosed herein is a cooking system for cooking food, the system including a housing having a hollow interior, a lid movable relative to the housing, at least one heating element associated with one of the housing and the lid, wherein the cooking system is operable in a plurality of modes including a conductive cooking mode and a convective cooking mode, wherein in the conductive cooking mode the cooking system is operable as a conductive cooker and in the convective cooking mode the cooking system is operable as a convection cooker.

A capacitive sensor includes a metal radiator disposed at an extreme end of a sensor assembly. A coaxial electrode is electrically interconnected to the metal radiator. The coaxial electrode has a center conductor, a dielectric around the center conductor, and an outer conductor, the center conductor being in electrical continuity with the metal radiator. An insulator configured to fit adjacent the metal radiator is configured to electrically and thermally isolate the metal radiator from selected electrical and thermal properties in an environment wherein the capacitive sensor probe is disposed. A connector is disposed distal from the metal radiator on the coaxial electrode, a portion of the connector being in electrical continuity with the metal radiator.

Various embodiments provide a method of frying. A method includes heating frying oil to a frying temperature and maintaining the frying oil at the frying temperature for a frying period. During the method no part of the oil exceeds 220° C. A system for using the method of frying includes a pot for holding a frying oil, a heating element for heating the frying oil, and a jacket surrounding the heating element. The jacket prevents direct contact between the frying oil and the heating element. The jacket is configured to uniformly distribute heat produced by the heating element within the pot such that the frying oil has less than 10 area % polymers at the end of heating and maintaining the frying oil at a frying temperature for a frying period.

Disclosed herein is a cooking system for cooking food, the system including a housing having a hollow interior, a lid movable relative to the housing, at least one heating element associated with one of the housing and the lid, wherein the cooking system is operable in a plurality of modes including a conductive cooking mode and a convective cooking mode, wherein in the conductive cooking mode the cooking system is operable as a conductive cooker and in the convective cooking mode the cooking system is operable as a convection cooker.

A fryer system includes a fryer and an oil storage assembly. The oil storage assembly includes a feed pipe coupled at a first end to a fry pot of the fryer and coupled at a second end to a pump assembly. The pump assembly includes a pump and a valve. The oil storage system further includes a storage pipe coupled at a first end to the pump assembly and coupled at a second end to a storage tank. The fryer system can perform an oil fill operation whereby the pump drives cooking oil from the storage tank to the fry pot and an oil drain operation whereby the pump drives cooking oil from the fry pot to the storage tank. A controller controls the oil fill and oil drain operations and transmits communications to a remote command center. The controller can also transmit communications to a driver display device.

Systems, methods, and computer program products for controlling a heating system in a fryer. At startup, a setpoint temperature for a cooking medium is set to a melt temperature. While in melt mode, each of a plurality of heating elements each located in a different region of a fry pot is sequentially activated to control an amount of heat provided to the cooking medium. Once the cooking medium has reached the melt temperature, the setpoint temperature is increased to a target cooking temperature. While in cooking mode, if an order to cook a food product is not received within a predetermined time period, the setpoint temperature is set to an idle temperature which is below the target setpoint temperature and above the melt temperature. The target cooking temperature is adjusted using a set of setpoint bias temperatures that is selected based on a cooking load.

A cooking system for cooking food includes a housing defining a hollow chamber configured to receive a food container. The housing has an upper portion defining an opening to the hollow chamber. A lid is configured to cover the upper portion of the housing and the opening to the hollow chamber in a closed position. The lid is movable to an open position where the lid does not cover the opening to the hollow chamber. At least one heating element associated with at least one of said housing and said lid. The cooking system is operable in a plurality of modes including a pressure cooking mode and a convective cooking mode. In the pressure cooking mode, the cooking system is operable as a pressure cooker, and in the convective cooking mode, the cooking system is operable as a convection cooker.

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.
