Abstract
Devices and methods for RF heating of food, using techniques which allow uniformity and/or controlled non-uniformity.
Claims17
A heater for dielectrically heating a load positioned in a cavity using UHF or microwave energy, the heater comprising:
- an UHF or microwave heating element for feeding UHF or microwave energy into the cavity;
- a memory storing a computer executable program;
- and
- a controller device communicatively connected to the memory, wherein when the computer executable program is executed by the controller device, the controller device performs operations comprising:
- selecting between first and second heating modes;
- identifying at least one absorption peak at a corresponding peak frequency;
- and
- for each identified absorption peak:
- determining a frequency band associated with the identified absorption peak, the frequency band including the peak frequency corresponding to the identified absorption peak, wherein the frequency band is determined to be broader when the first heating mode is selected than when the second heating mode is selected;
- and
- controlling the UHF or microwave heating element to heat the load by feeding the cavity with UHF or microwave energy at frequencies of the determined frequency band.
