Industrial Rotary Microwave Vacuum Dryer SUS 304 PLC Panel Control

SUS304 PLC Panel Control Rotary Microwave Vacuum Drying Machine

Application Range

The microwave drying equipment adopts the combination of microwave heating and vacuum dryer, which can well meet the needs of faster production of high-quality heat-sensitive materials.

The huge advantage of microwave drying over conventional heating is that heat is generated by the direct conversion of electromagnetic energy into molecular kinetic energy, so the heat occurs inside the material. Especially in vacuum drying, this advantage is very obvious for viscous and bulky substances with low thermal conductivity. Suitable process control and even explosion-proof applications can be achieved. 

Vacuum dryers can be integrated into continuous production lines for the handling of granules, powders, lumps, and hard materials on tooling.

Microwave can heat the crushed material rapidly, vacuuming can make the water in the crushed material boil at low temperature, the water vapor generated can break the cell wall, release the internal effective components, and form a porous and easy-to-rehydrate structure in the crushed material, complete It is widely used in drying of vegetables, fruits, traditional Chinese medicine and meat to preserve various components in scraps.

Features of Microwave Vacuum Drying Machine:

(1) The drying rate is high. Common drying methods such as hot air drying, for the material, heat is transferred from the surface to the inside, while the moisture migrates from the inside to the outside, and the temperature gradient is opposite to the direction of the moisture transfer, which will lead to a decrease in the drying rate. Microwave drying is to directly apply energy to the entire material through microwaves, so that the material as a whole is heated evenly, which greatly shortens the heating time; at the same time, due to the existence of pressure migration power, microwave drying has the characteristics of drying from the inside to the outside, which overcomes the need for conventional drying. Due to the fact that the outer layer of the material is first dried to form a hard shell, which prevents the internal moisture from continuing to move out, the drying rate is high.

(2) Improve drying quality. Microwave heating is uniform heating inside and outside the material at the same time. The place with high water content absorbs more radiant energy, and the dry matter is relatively small, which can be dried more quickly, which plays a role in the automatic balance of heat distribution; at the same time, vacuum drying can reduce the amount of water. The high evaporation temperature makes the material evaporate rapidly at a lower temperature, avoiding the burns, coking, crusting and hardening caused by simple microwave heating due to overheating, and at the same time avoiding oxidation, thus improving the drying quality. Especially in the case of heat-sensitive materials in the fields of medicine, food and chemical industry, low temperature and rapid drying conditions are required; at the same time, for food and medicine, due to the biological effect of microwaves, the purpose of sterilization can be achieved at a lower temperature.

(3) Low cost and no pollution. Microwave vacuum drying is used, without electric heating drying equipment and steam heating equipment, microwaves directly interact with materials, without heating air, large-area walls and conveying equipment; Absorbed by materials, it will not leak to the outside, and will not cause environmental pollution. Its energy consumption is 1/3 to 1/4 of ordinary drying equipment, far lower than infrared drying.

(4) High degree of automation control. Immediate heating and termination can be achieved as long as the microwave power is controlled. The application of human-machine interface and PLC can carry out programmable automatic control of heating process and heating process specification, flexible and simple operation, one-key setting, and the system is fully automatic.
