  General Introduction

  Microwave is a sort of electromagnetic wave which frequency is 300MHz to 300GHz. The water molecule in medium materials is polar molecule, under the effect of the rapid change of electromagnetic field, its polarity orientation will alter with the changes of the external electric field with the high-speed, causing the movement 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, drying, sterilize, roasting, puffing and a series of physical and chemical processes.

  Features of Design

  1.Fast heating

  Microwave heating is completely different with traditional heating mode. It makes heating medium become heater, do not need heat transfer process. Although thermal conductivity is poor materials, also can achieve heating temperature in a very short time.

  2.Save energy and efficiency

  Because materials contain water absorb microwave easily and fever, so in addition to a small amount of transmission loss outside, almost no other loss, so high thermal efficiency, save energy.

  3.Heating even

  No matter how shape of each part of the body, microwave heating all can make the object and evenly infiltration and electromagnetic wave list to produce the heat. So heating good uniformity, won't appear the endogenous phenomenon focal.

  4.Mouldproof, sterilization, fresh

  Microwave heating has thermal and biological effect, can sterilize and mould proof in low temperature.Due to heating rapidly, the time is short, can maximum limit save material activity and thevitamin original colour and lustre and nutrition of food.

  5.Craft is advanced, control easily

  Microwave heating just have the basic conditions ofwater, electricity, as long as control power, can realize microwave heating or terminate immediately, use microwave equipment can process automation control of heating process and heating process specification.

  6.Covers less area, safety and harmless

  Because microwave can be controlled in made of metal heating indoor and wave, so microwave leak is few, no radiation hazards andharmful gases,do not produce the waste heat and dust pollution; Neither polluting food,also do not pollute the environment.
