Food heating method of radio-frequency heating equipment

Abstract

The invention provides a food heating method of radio-frequency heating equipment. The method comprises the steps of obtaining a cooking worksheet corresponding to received food information, wherein the cooking worksheet includes multiple cooking subsidiary stages which are arranged according to a preset sequence; sequentially executing all the cooking subsidiary stages according to the preset sequence. Each cooking subsidiary stage comprises the steps of obtaining and determining, wherein multiple energy absorbing rates of heated food under radio-frequency heating with different frequencies are obtained, the maximal energy absorbing rate is determined as the food absorbing capability, and the frequency corresponding to the maximal energy absorbing rate is determined as a main working frequency of radio-frequency heating modules; heating, wherein the radio-frequency heating modules conduct heating for a preset duration in real time according to the corresponding main working frequencyand a working frequency determined by a corresponding frequency deviation value; repeating of the step of obtaining and determining; finishing. By means of the food heating method of the radio-frequency heating equipment, the speed of cooking the food can be greatly increased, and excellent mouthfeel is achieved.

Description

technical field [0001] The invention relates to the field of radio frequency heating equipment, in particular to a food heating method of radio frequency heating equipment. Background technique [0002] With the continuous development of home appliances, people put forward higher and higher requirements for home appliances. For example, many people are not satisfied with heating food only through electric heating, and often use microwave ovens or integrated microwave ovens, etc. A device that uses microwaves to heat food to obtain rapid heating performance and a better taste of cooked food, and can better retain food nutrients and color. A microwave oven is generally composed of a power supply, a magnetron, a waveguide, a control circuit, and a furnace cavity. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, which are then coupled into the furnace cavity ...

AI Technical Summary

Problems solved by technology

In the process of realizing the present invention, the inventors of the present application found that although the microwave oven heating food using the magnetron as the microwave emission source in the above-mentioned scheme of the prior art is fast, the heating uniformity of the food is poor, the taste is not good, and it is suitable for cooking. narrow range
