What is Microwave drying?

Microwave is an electromagnetic wave whose frequency is between 300MHZ~300GHZ and wavelength is between 1mm ~1m. the characteristics of microwave usually shows penetration, reflection and absorption . For glass, plastic and porcelain, microwave will penetrate it without being absorbed. For water and food, it will absorb microwave and heating by itself. For metal material, it will reflect the microwave.
Microwave drying : Water molecule is polar molecule, it will change its polarity and friction motion caused by the effect of high speed change of high frequency electormagnetic field. Then the microwave electromagnetic filed energy can be converted into heat energy and achieve the purpose of drying. Due to the strong penetrability, microwave can heat up the material outside and inside simultaneously and evenly, so that won't appear the condition that the outsie dry but inside wet. The formation of body heat source state shortens the time of heat conduction and save a lot of drying time.
Microwave sterilization:Microwave sterilization temperature is from 70℃~105℃, period is from 90 seconds ~180 seconds. Microwave thermal effects can change the bacterial protein and make bacteria to die owing the loss of nutrients, reproduction and survival.Meanwhile, Microwave eletromagnetic field can make normal growth and stability of the genetic breeding of bacteria nucleic acid【RNA】 and deoxyribonucleic acid【DNA】 number of hydrogen bonds slack, breakage and recombination, thereby inducing genetic mutations, chromosomal aberratiuons and even rupture.

What is the characteristic of microwave drying ?

1.Equipment effect at once, power adjustable, transmission speed adjustable, no thermal inertia residues, compare with the convenentional process equipment to save energy by 50%;
2.Make the material itself become body heat source state, owing without heat transfer process, it can achieve the drying teperature within a very short time;
3.Owing to the strong penetrability, microwave drying can heat up the materal inside and outside stimutalouly and evenly and will not appear the conditon that the outsie dry but inside wet;
4,Microwave can fast sterilize nder low temperature sterilization, so the material can store for a long time without mildew;
5.Due to the fast drying speed , microwave drying can maximally save the activity of the materials, nutrition ingredient and the original color;
6.Owing to microwave leakage controlled in metal drying chamber and the waveguide, there is no radiation damage and harmful gas emissions, meanwhile, it wouldn't product waste heat and dust pollution, so microwave drying is an efficient and economic enviromental drying mode.
