Product Description

1. Summarize:

 In traditional heating methods, heat is conducted by convection, conduction, and radiation, and penetrates from the outside to the inside. However, it is difficult to conduct heat through convection in air under vacuum conditions. Only heat conduction and radiation are used to provide heat energy to the material. High surface temperature The internal temperature is low, the temperature difference between inside and outside is large, and the temperature is difficult to control. Therefore, the conventional vacuum drying method has slow thermal conduction speed, large energy consumption, low efficiency, and long drying time.

Microwave heating is a type of radiant heating, in which microwaves directly act on an object, causing it to be heated both inside and outside, without having to transfer heat by convection or conduction. Therefore, the heating speed is fast, the thermal efficiency is high, the processing time is short, and the temperature inside and outside the material is uniform. Energy conservation, high drying efficiency, and good drying quality. Intelligent static microwave vacuum drying equipment is a new type of microwave energy application equipment that combines microwave energy technology and vacuum technology and is controlled by high-tech intelligence. It combines the advantages of microwave drying and vacuum drying, while overcoming conventional vacuum. The disadvantages of high drying temperature, long time, large energy consumption, drying temperature in the general material, drying temperature 30-60 degrees Celsius, with high drying yield, good quality, low processing cost, and can accurately control the moisture through intelligent control system advantage. In addition, when the oxygen content is low at low temperature and low pressure, the oxygen content of the material to be dried is reduced and the oxidation reaction of the material to be dried is weakened, which ensures the flavor, appearance and color of the material. It is easy to dry the heat-sensitive material, especially the extract of traditional Chinese medicine extract, beef sauce, and chemical raw materials. The low temperature drying of agricultural products has its unique advantages.

2. Application:

Microwave vacuum dryer is mainly used for dehydration drying 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 crystal water, enzymes drying of preparations; vacuum extraction of medicinal herbs; suitable for laboratories of scientific research institutes.

3.Vacuum drying principle and features:

When the equipment is running, microwaves are first generated by the magnetron and input into the microwave cavity through the feeding device. The moisture in the material in the cavity is heated and evaporated under the action of the microwave energy, and the water vapor is eliminated through the dehumidification system to achieve the purpose of drying. Bacteria in the material are killed by the biological and thermal effects of microwave electromagnetic fields. Since the microwaves directly act on the materials, the drying temperature is low, the speed is high, and the loss of active ingredients in the medicine is small.


The vacuum drying of food materials is the same as the drying under normal pressure, except that the evaporation temperature of moisture is lower than the evaporation temperature under normal pressure under vacuum conditions. The higher the degree of vacuum, the lower the evaporation temperature, so the entire drying process can be performed at a lower temperature.


1. High efficiency: its production efficiency is 4 times that of conventional drying;

2. The heat distribution is good: due to the selective heating of water molecules by microwaves, the internal moisture content of the material is high, from the inside to the outside during heating, consistent with the direction of moisture diffusion and the temperature difference between inside and outside is small, and the phenomenon of uneven distribution of the conventional dry heat does not occur. ;

3. Easy to control: The vacuum degree adjustment of the microwave can be controlled through PLC programming. The outside is equipped with a special sight glass to observe the whole process of drying;

4. High quality: Effective ingredients are not easy to decompose and damage at low temperature, but also have the effect of disinfection and sterilization, extending the shelf life;

5. Economical energy consumption, high degree of automation.

6. Low-temperature and high-efficiency: It is known that the gas pressure is reduced and the boiling point of water is reduced at the same time. For example, at a standard atmospheric pressure, the boiling point of water is 100°C, and at 0.073 atmospheres, the boiling point of water is 40°C. Under vacuum conditions, heating the object causes the internal moisture of the object to evaporate without any temperature rise. Microwave vacuum cryogenic heat-sensitive materials, drying speed is much higher than conventional drying, the ratio is generally more than a dozen or even dozens.

7. Improve quality: Dry in low temperature, oxygen-free environment to better ensure product quality.
