The present invention generally relates to thawing a cryogenically frozen sample. The systems, devices, and methods may be used to heat a sample holder, the sample holder configured to receive a sample container holding the frozen sample. A sample thaw start time may be identified by measuring a temperature of the sample container and/or a temperature of the sample. A sample thaw end time may be calculated as a function of the sample thaw start time. In some embodiments, the same thaw start time may be identified by a significant change in a first derivative of a warming curve of recorded temperature measurements. The sample end time may be calculated by adding a constant to the sample thaw start time. The constant may be the average sample thaw time per the sample container.

A method for the provision and conservation of communal meals is provided, in which a plurality of foodstuff and meal components are brought into packaging units and sealed therein following the preparation of said food by heating at a temperature of at least 75° C. A water bath at a temperature of less than 3° C. is used to cool the sealed packaging units in order to bring the meal component from a core temperature of 65° C. or higher to a core temperature of 3° C. or lower within no more than 90 min. Methods for regenerating the cooled packaging units for consumption are also provided, in a water bath having a temperature of 80°-90° C.

A method of arranging an induction coil in a food service well includes supporting, by supports in an extended position, the induction coil at a first height in the food service well, rotating the supports from the extended position to a retracted position, and supporting, with the supports in the retracted position, the induction coil at a second height in the food service well, the first height different than the second height.

A cooking machine equipped with such a lid assembly, wherein, the lid assembly includes: a cover lid, venting holes arranged at a middle part of the cover lid; a baking assembly arranged on the cover lid and communicating with the venting hole; an air discharging tube passing through the cover lid; a pressure limiting valve arranged on the air discharging tube; a sealing hood detachably arranged below the cover lid and including a first annular position-limiting protrusion protruding upward, the first annular position-limiting protrusion surrounding the outer side of the venting holes and located at the inner side of the air discharging tube; a first sealing part includes a first sealing lip, a second sealing lip, and a position-limiting part in cooperation with the first annular position-limiting protrusion to fix the first sealing part to the sealing hood. The first sealing lip cooperates in a sealed manner with the outer face of the first annular position-limiting protrusion, and the second sealing lip cooperates in a sealed manner with a lower surface of the cover lid, to separate the air discharging tube from the baking assembly.

A kitchen appliance is disclosed. The kitchen appliance comprises: a user interface control unit for interacting with a user; a plurality of driver units configured to control power supply to a plurality of coils; and the plurality of coils configured to heat one or more cookers based on electromagnetic induction effect, wherein each driver unit is configured to generate a control signal for a corresponding coil of the plurality of coils, and the control signal is used for controlling the power supply to the corresponding coil by controlling turn-on or turn-off of an insulated gate bipolar transistor (IGBT) in a single-pipe module.
