Product Introduction
Microwave vacuum dryer is a new generation of new, efficient drying and sterilization equipment successfully developed for food engineering, pharmaceutical engineering, bioengineering, chemical engineering, material engineering and deep processing of agricultural and sideline products by utilizing the mature microwave energy application technology. It has significant advantages such as fast drying speed, small energy consumption efficiency ratio, and uniform drying and sterilization effect of materials. It can directly replace the traditional dryer for material dehydration and drying. ; The sterilization capability of microwave energy can also be used to sterilize Chinese medicinal materials, Chinese medicinal powders and other materials. It is mainly used for dehydration, drying and sterilization of high value-added and heat-sensitive agricultural and sideline products, health products, food, medicinal materials, fruits and vegetables, chemical raw materials, etc. ; Used for low-temperature concentration of chemical products, removal of crystallization water, drying of enzyme preparations, etc. Microwave vacuum dryers are suitable for laboratories in scientific research institutions.

Product Features
1. Energy saving and high efficiency: Conventional vacuum drying equipment, because in vacuum conditions, it is very difficult to transfer heat through convection and can only be conducted by conduction, the heating speed is slow, the drying cycle is long, and the energy consumption is large. Microwave vacuum drying equipment uses radiation energy transfer to heat the medium as a whole without the need for other heat transfer media. It avoids the above shortcomings, so it is fast, efficient, the drying cycle is greatly shortened, and energy consumption is reduced. Compared with conventional drying technology, the efficiency can be improved by more than four times.
2. Uniform heating: Since microwave heating heats the inside and outside of the material at the same time, the temperature difference between the inside and outside of the material is small, and the inconsistent heating between the inside and outside that occurs in conventional heating will not occur, greatly improving the drying quality.
3. Easy to control: Due to the rapid adjustment of microwave power and the characteristics of no inertia, it is easy to control in time and facilitate the adjustment and determination of process parameters. The microwave power can be continuously adjusted as the temperature of the material changes. The human-machine interface and PLC can be used to perform programmable automatic control of the heating process and heating process specifications.
4. The equipment is small in size and easy to install and maintain.
5. Extended shelf life: The biological effect of microwave energy can sterilize and prevent mildew at lower temperatures. Due to the fast heating speed and short heating time, the activity, vitamins, original color and nutrients of the material can be preserved to the maximum extent.
6. Environmental protection: Microwave vacuum equipment does not produce "three wastes". Since the microwave energy is controlled in the heating chamber and waveguide made of metal, there is very little microwave leakage and can be controlled at 2.0mw/cm 2 , no radioactive hazards and harmful gas emissions, no waste heat and dust pollution, neither polluting materials nor the environment.
7. Significant economic benefits.
Microwave vacuum equipment has significant economic and social benefits in terms of energy saving, consumption reduction, product quality improvement, safety and hygiene, and low equipment investment cost.
