The electrical fryer further includes: a knob mechanism comprising a knob presenting an oil filtering position and at least one heating position; an oil filtering control mechanism connected between the knob mechanism and the oil filter; a temperature control mechanism comprising a switch assembly being drivingly connected with the knob mechanism; wherein, the knob is turned so as to switch between the oil filtering position and said at least one heating position, and when the knob is turned to the oil filtering position, the knob mechanism drives the oil filtering control mechanism to open the oil filter and the knob mechanism controls the switch assembly to switch it off so that the electrical heater is not energized, and when the knob is turned to said at least one heating position, the knob mechanism controls the switch assembly to switch it on so that the electrical heater heats the inner pot.

Some implementations of the described methods relate to a process for frying coffee beans (and/or another food product) in a fry medium (such as cooking oil) and then centrifuging the coffee beans (and/or other food product) to remove a significant portion of the fry medium. Although the frying and centrifugation can occur in separate devices, in some cases, the described systems comprise a device that acts as both a fryer and a centrifuge. Indeed, in some cases, after the coffee beans (or other food product) has been fry roasted in a perforated container (e.g., a basket), the fry medium is drained from the container, and container is spun. In some cases, liquid nitrogen is also applied to the beans (or other food product), before and/or after being fry roasted. Other implementations are described.

An electric deep cooker including a main body and cover adapted to fully enclose food therein that includes a plurality of main electric heating elements connected along the interior surfaces of the main body and cover and are adapted to uniformly heat and cook food through its entire outer surface from the outside in, and further includes an electric interior heating element attached to the cover and adapted to be placed within the food being cooked and thereby heat and cook the food from the inside out while the plurality of main heating elements heat and cook the food from the outside in, to thereby uniformly and properly heat and cook the food, and in a shorter amount of time, than prior art electric deep cookers, and without the need to rotate the food within the main body of the electric deep cooker.

An induction fryer includes: a case having a space with an open upper part; a lid installed by means of a hinge at an upper part of the case; a frying container, installed in the case, for containing oil so as to be able to fry frying ingredients; a frying basket having a space and a fixing rod formed therein so as to be lifted up and down; an induction heating unit installed on an outer circumferential surface of the frying container and having a coil and a plurality of magnets fixed to an assembly body so that electric energy is converted into thermal energy by electromagnetic induction and; and a control unit for electrically controlling the induction heating unit so that the frying ingredients being fried by the electromagnetic induction phenomenon, wherein the coil is fixed only by fixing the magnet to the assembly body without using an adhesive.

A deep fryer tank made of a deep-drawn metal material includes a bottom and several sides connected to the bottom by curves, at least one of the sides having at least one rigidifying lateral indentation forming a lateral recess extending in one direction.

At least one side has at least one other rigidifying lateral indentation forming another lateral recess extending in another direction, and the at least one rigidifying lateral indentation intersects the at least one other rigidifying lateral indentation.

An electric deep fryer comprises a deep fryer tank of the aforementioned type.

A deep fat fryer (1) comprising: a housing (2), a pot (3) adapted to contain a cooking medium, one or more heating elements (4a, 4b), external to said pot (3), for heating a cooking medium contained in said pot (3), a temperature sensor (5) adapted to measure the temperature of a cooking medium contained in said pot (3), a control unit (9), controlling the electrical components of the deep fat fryer (1). The deep fat fryer (1) comprises one or more heat-shield elements (6a, 6b) arranged for slowing down the heat transfer from said one or more heating elements (4a, 4b) to a cooking medium contained in said pot (3).

An easy handling and installable fryer for cooking materials in an electric-field carrying space includes an oil pot base including an oil pot having an inner surface at least partially being a metal plate, and a metal mesh basket placeable in and out of the pot. The base includes a pot fastener that allows the basket to be placed in the pot without electricity conduction to the inner surface, and a conductor including a conducting electrode on an upper portion of a pot surface opposing a handling side, and insulated from the inner surface that conducts an alternating current to the basket in the pot. The basket includes a basket fastener that allows, with the pot fastener, the basket to be placed in the pot without electricity conduction to the inner surface, and an electricity receiver that receives electricity from the electrode and conducts electricity to the mesh basket metal.

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.

An automatic cooking system is provided to reduce and/or optimize the amount of cooking medium required to operate the fryer, while improving the temperature and flow characteristics of cooking medium in the fryer. To this end, the cooking vat of the system is designed with one or more heating elements and one or more lanes for flow of cooking medium and food products between inlet and outlet ends, with the heating elements defining a low profile and/or being mounted externally to the cooking vat to avoid impeding flow of the cooking medium. One example of such a heating element is a printed heating element that is coupled to or directly printed on the cooking vat. This arrangement reduces the total volume of retained cooking medium needed to flow and move food products along a length of the cooking vat during a cooking process.
