The unique mechanism of microwave make the material heated inside and outside at the same time.Vacuum,in other word in a negative pressure,the material can be dried in a low temperature.This makes the material being heated evenly,maintain its originalcolor,and the material composition don’t be changed.All in all, microwave vacuum drying equipment effectively guarantees the quality of raw materials.
Compared with conventional vacuum drying equipment:
1)Penetration: because it is in vacuum situation when using conventional vacuum drying equipment,heat cann't transfer in the form of convection and can only conduct.So the heating speed is slow,drying time is long and the energy consumption is excesive.However,Microwave vacuum drying equipment adopts radiation way to transfere energy and it heat wholly without any medium.Itavoids the above shortcomings.
2)Evenly: microwave heating is in and outside of the material at the same time,the temperature difference is very small in and outside of the material.So it is more evenly when drying materials,and the heating efficiency is greatly increased.
3)Quickly: because of the penetration of the microwave and the radiation way to transfere energy, materials is heated inside and outside at the same time.Thus the drying speed is greatly improvedl.
