Benefits of using a microwave vacuum dryer
Western countries as early as the 1980s began for industrial microwave vacuum drying equipment development and practical application to obtain good results . France International Microwave Corporation microwave vacuum drying equipment, processing seedless raisins, the traditional craft 65 ℃, 24小时hot air drying becomes 50 ℃, 5小时microwave vacuum drying , the product quality and yield are greatly enhanced.

Microwave Vacuum Drying of several major advantages:

1 , energy efficient
Efficient conventional vacuum drying equipment heated by steam , the need for heating from the inside to the outside , slow heating takes a lot of coal, while the microwave vacuum drying equipment is used in electromagnetic heating , no heat transfer medium heated directly inside the object , heating speed , one kilowatt of microwave energy at room temperature within 3-5 minutes in the water is heated to 80 ℃, to avoid the above drawbacks , the speed , high efficiency , greatly reducing the drying cycle , reduce energy consumption . Compared with conventional drying techniques can improve work efficiency more than four times .

2 , uniform heating
Because microwave heating , from the inside to the outside on the material while heating , the material temperature difference is small , there will not occur in conventional heating and external heating inconsistent condition , resulting puffing effect , beneficial pulverized greatly improved the quality of the dried .

3 , easy to control , easy to automate continuous production and
Because microwave power can be adjusted quickly and without inertia characteristics , easy real-time control , at 40 ℃ -80 ℃ can be adjusted between temperatures.

4 , prepare small size, easy installation and maintenance , do not take up much of the space.

5 , good product quality
Microwave vacuum drying equipment to extend the shelf life of food , preserving food the original flavor and nutrients , keep raw physical activity, enhance functional health food , improve the added value of agricultural products and so on. Compared with the conventional method , the processing of the product quality has improved greatly .

6, with microwave sterilizer , microwave sterilization efficacy , product safety and health , long shelf life .

7 , significant economic benefits
The traditional drying time required is very long, very slow, high energy consumption , high processing costs . Microwave heating , can save a lot of energy, improve the speed of heating and drying . This is because the microwave penetrating in the object is heated, does not require any media both inside and outside the material and can be heated . According to the domestic information shows that the microwave heating apparatus of the material , the speed and effectiveness of the conventional method of heating 4 to 10 times .

From the above described features , the energy conservation, energy , improve product quality , health and safety aspects of equipment investment and low cost can be seen its remarkable economic and social benefits . The invention of the microwave vacuum dryer for many areas of our national economy and scientific research departments to provide a modern, high-tech drying equipment.
