China supplier microwave dryer and dehydrator machine for shiitake, often colloquially shortened to microwave, is a kitchen appliance that heats food by bombarding it with electromagnetic radiation in the China supplier microwave dryer and dehydrator machine for shiitake spectrum causing polarized molecules in the food to rotate and build up thermal energy in a process known as dielectric heating. China supplier microwave dryer and dehydrator machine for shiitake 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.

Drying principle
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 ,puffing and a series of physical and chemical processes ,and so ,microwave heating is achieved.
Features of Design
1.Homogeneous and quick heating
Microwave has penetrability and changes with the frequency,the depth of penetration normally from several mm to tens of cm,both the outside and inside of the material can be heated at the same time,therefore avoiding the phenomenon of overheating of the outside while the inside uncooked.Microwave heating changes the heated object to be the heating object,no heat conduction will be necessary.It takes short time for the poor heat conductivity material to reach the heating temperature.The efficiency will be increased greatly by using the microwave,and also the productivity and the quality.
2.Power saving and high efficiency
Material containing water can easily absorb the microwave and be heated,thereby there is almost no loss except the loss during the transportation,therefore high heating effect with low power consumption.
3.Mold proofing,sterilization and keeping freshness
Microwave heating has both heat effect and biological effect,can sterilize and proof mold in lower temperature.Because of the rapidly heating within short time,microwave heating can mostly save the activity,color and nutritious parts of the material.
4.Advanced technology with auto-control
The heating and the termination can be realized by the control of the power of the microwave,there will be no thermal lag.It can be automatically controlled by control panel.
5.Selectivity of heating
Microwave has different functions for material with different dielectric properties,this is beneficial to heating process,because water molecule absorb microwave the best.The part containing high water absorbs more microwave power than the one containing the less water,this is the selectivity of the microwave .While heating wood and paper,this feature can be used to heat and dry homogeneously.Please pay attention that some material will absorb the microwave better at higher temperature,the positive feedback causes the temperature of this material to increase dramatically.It’s necessary to set reasonable heating process.
6.Safety and harmless,the improvement of working environment
The microwave can be controlled in the heat conducting room made of metal and waveguide tubes,so there will almost be no leakage of microwave,no the harm of radiation and the disposal of harmful gas,no waste heat and dust,thus greatly improving the working environment and intensity of labour.
