High Quality Commercial Convenient Hot-Air Convection Oven with Instrument

Products description

A microwave oven, often colloquially shortened to microwave, is a kitchen appliance that heats food by bombarding it with electromagnetic radiation in the microwave dryer spectrum causing polarized molecules in the food to rotate and build up thermal energy in a process known as dielectric heating. Microwave dryers heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm of a dense (high water content) food item; food is more evenly heated throughout (except in thick, dense objects) than generally occurs in other cooking techniques. The microwave dryer can Sterilize the food during the drying process by heat and the influence on the protein, RNA, DNA, cell membrane and so on.

Working Principle:

Microwave is a sort of electromagnetic wave which frequency is 300GHZ. The water molecule in medium material is polar molecule, under the effect of the repaid change of electromagnetic field, it is polarity orientation will alter with the changes of external electric field with high-speed, causing the movements and friction of molecule, so that the microwave field energy can be converted to heat energy in medium to rise the temperature of materials, accomplishing heating, puffing and a series of physical processes and so microwave is achieved.
