Industrial Microwave Vacuum Dryer

Industrial Microwave Vacuum Dryer is mainly used for dehydration and drying of high value-added and heat-sensitive agricultural and sideline products, health products, food, medicinal materials, fruits and vegetables, chemical raw materials, etc.; 
Under the condition of vacuum, low evaporation temperature of the water, realized the low temperature drying, intact to keep the processing material is original color, aroma, taste and nutrition, avoid the active ingredient of the oxidation in the material, products after good water .
for low temperature concentration of chemical products, removal of crystal water, enzymes Preparation drying, etc.; vacuum extraction of Chinese herbal medicine; suitable for laboratories in scientific research institutions.
To material heating by microwave equipment, its speed and efficiency is 4 ~ 20 times as high as that of the conventional heating method.

Loyal Microwave Vacuum Dryer Design :

1.Using four magnetron, high efficiency, strong ability to resist load, long life (7000 hours). using the fan for cooling protection device,in order to better protect the stability of the magnetron and service life.

2.Use a special transformer with overheating protection system .

3.Adopt the ultra-high voltage capacitor, the specifications of 1.05 uf 2500 v, more stable and durable than the conventional 1.0 uf 2300 v.

4.Using high-voltage silicon stack, its reverse repetitive peak voltage of 12 kv, positive rectifier current is 450 ma, and checked by practice, durable, completely suitable for the microwave equipment required.

5.Use the circular heating cavity (304 # stainless steel plate, thickness is about 4mm), ensure that it can withstand pressure, long-term use of deformation, conform to the requirements of the GMP pharmaceutical industry and food industry "QS" requirements. Elaborate design phase complementary form microwave energy supply, ensure the normal operation of magnetron completely, the output matching superior performance, prolong service life.

6. According to characteristics of material drying, microwave heater in strength distribution, used on the power density distribution of the temperature of the material as required in order to facilitate random set, and has a corresponding thermal process, make the material drying out evenly, not gelatinization.

7.Using heating system.Well-designed phase form complementary feed mouth, after a large number of theory and practice and design of the microwave waveguide, so as to ensure the normal operation of magnetron completely, the output matching performance is superior, the uniform heated material more thoroughly and lengthen the service life of the microwave tube and transformer core, such as the original.

8.Use stainless steel material, beautiful and generous.

9.In the middle of the heating chamber straight large opening door, choke devices, microwave equipment to ensure long-term use does not leak, ensure use safety, the operation is convenient.

10.The cavity body adopts horizontal rotating tray technology, make dry more quickly and evenly. Wheel diameter is about 300mm.

11.The vacuum pump and the platoon is wet chamber link at the bottom of the chamber and the upper.

12.Microwave generator and the power part is equipped with cooling device, ensure that all electrical components without damaging long-term work, not aging.

The principle of Industrial microwave vacuum dryer:

The working principle of Industrial microwave vacuum dryer is similar to that of microwave vacuum dehydrator.It is a drying technology based on sublimation principle. It freezes the dried substance rapidly at low temperature, and then sublimates the frozen water molecule directly into the water vapor escaping under appropriate vacuum environment.

In the microwave drying process, the temperature gradient, heat transfer and vapor pressure migration directions are consistent, which greatly improves the water migration conditions in the drying process. As a whole, the inner drying first overcomes the problem that the outer layer of the material dries first and forms hard crust which prevents the internal moisture from continuing to move out in the conventional drying process.

Which Market Did The Loyal Industrial Microwave Vacuum Dryer?

Questions and Answers:

How does vacuum drying work?

Vacuum drying is to put materials under vacuum negative pressure, so that the boiling point of water is reduced. The boiling point of water under one atmospheric pressure is 100 ℃. Under vacuum negative pressure, the boiling point of water can be reduced to 80 ℃ , 60 ℃, 40 ℃ and start to evaporate.

Industrial microwave vacuum dryer 30 solves the problem of drying heat sensitive materials. During vacuum drying, high-energy water molecules diffuse to the surface and evaporate at low pressure, preventing oxidation and maintaining the color, texture, and flavor of the dried product.

Factors affecting for Industrial microwave vacuum dryer:

•  Type and size of materials

•  Equipment vacuum

•  Microwave power

•  Microwave working time
