Product Description

Industrial microwave vacuum dryer


In the traditional heating method, the heat is carried out by convection, conduction, and radiation from externally to internally, but it is difficult to carry out heat transfer through air

convection under vacuum, and heat is supplied only to the material by means of heat conduction and radiation. The surface temperature is high, the internal temperature is low, the internal and external temperature difference is large, the temperature is difficult to control. Therefore, the conventional vacuum drying method heat conduction speed is slow, energy consumption is big, efficiency is low, drying time is long.

Microwave heating is a kind of radiation heating, the microwave has a direct effect on the object, so that it is heated at the same time inside and outside, without convection or conduction to transfer heat, so the heating speed and thermal efficiency are high, processing time is short, uniform temperature inside and outside the material, energy saving, high drying efficiency, good drying quality.

Intelligent static microwave vacuum drying equipment is a new microwave energy application equipment through a high-tech intelligent control with combination of microwave energy technology and vacuum technology, which combines the advantages of microwave drying and vacuum drying, while

overcoming shortcomings of conventional vacuum in which  drying temperature is high, time is long and energy consumption is big.

In the general material drying process, the drying temperature is about 30-60 degrees Celsius, with high drying yield, good quality, low processing costs, as well as precise control of water content by intelligent control system. In addition, the oxygen content is low at low temperature and low pressure, and the oxidation reaction of the dried material is weakened, so as to ensure the flavor, appearance and color of the material. It has unique advantages to easily dry the heat-sensitive material, especially the extract of

Chinese medicine, beef sauce, chemical raw materials and agricultural products at low temperature.

Working principle

Microwave drying is such a drying method that material absorbs microwave energy which can be converted into heat, so that the material has an overall heating both internally and externally at the same time and it is completely different from other conventional drying methods.

Conventional drying method is based on the principle of heat conduction, convection and radiation which transfer heat from external to internal, inevitably there is a temperature gradient in the material, therefore, heating is uneven and there may result in local overheating.

Microwave drying technology is different from the conventional drying method, which is by means of high frequency reciprocating motion of the dipolar molecule of the material, resulting in internal friction heat which heats material, without any heat transfer process, and the material is heated both internally and externally at the same time with high speed drying and uniform drying result, and energy consumption is far less than traditional heating. Main features

1, high efficiency: its production efficiency is 4 times the conventional drying;

2, the heat distribution is good: microwave has a selective drying on water molecules; the internal part of the material has high water content, heating from internal to external, consistent with the direction of diffusion of water and the internal and external temperature difference is small, there will be no uneven heat distribution phenomenon compared to regular drying;

3, easy to control: microwave vacuum adjustment can be programmed through the PLC control, external is installed  with a dedicated mirror, you can observe the whole process of drying;

4, good quality: the active ingredient is not easy to be broken down and destructed due to the low temperature, and also it has disinfection and sterilization effect so as to extend quality life;

5, low energy consumption, high degree of automation.

6, low temperature and high efficiency:  Microwave vacuum drying machine dries heat-sensitive substances, drying rate is also much higher than the conventional drying, the ratio is generally more than a dozen or even dozens.

7, improve the quality: drying in low temperature and anaerobic environment guarantees a better quality of the product.


Vacuum microwave dryer is mainly used for high value-added and heat-sensitive agricultural and sideline products, health products, food, herbs, fruits and vegetables and chemical raw materials; used for low temperature concentration of chemical products, removal of crystal water and drying of enzyme preparations; and also used for vacuum extraction of Chinese herbal medicine; and applicable to the laboratory of scientific research institutions
