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.
Microwave vacuum drying technology combines the advantages of microwave technology and vacuum technology, and is extremely beneficial for the drying of heat sensitive materials. Compared with the conventional drying method, it has the characteristics of low energy consumption, short drying time, low working temperature, good product color and high vitamin preservation rate. It is suitable for low-temperature drying sterilization and low-temperature concentration of heat-sensitive, easily oxidizable, high-viscosity, high-concentration liquid materials in medicine, chemical, food, biological products, agricultural and sideline products, such as: Chinese herbal extract, ginseng, donkey-hide gelatin, antler, Vegetables, flowers, biochemical products, health products, additives, etc.
