Product Introduction

1、 The principle of microwave heating drying:
Microwaves are electromagnetic waves, and the microwave frequencies used in industry are 915MHz and 2450MHz. High voltage direct current is converted into microwave energy through the resonant cavity of a magnetron. When the magnetron emits microwave energy at a frequency of 2450MHz, the zinc sulfate water molecules placed in the microwave heating cavity oscillate at a frequency of 2.45 billion kilohertz per second. The zinc sulfate molecules vibrate in a high-frequency magnetic field, collide and rub with each other to generate heat energy, causing the temperature of zinc sulfate to rise. The high-frequency oscillation friction between molecules rapidly increases the temperature of zinc sulfate, reaching 200 degrees Celsius for about 2 minutes. The free water and crystalline water inside the zinc sulfate evaporate, and the water vapor is discharged through a dehumidification fan to achieve the drying effect of zinc sulfate. Due to the controllable temperature of microwave heating drying, the drying temperature and speed can be adjusted according to the customer's moisture requirements for zinc sulfate. Microwave drying of zinc sulfate can achieve a moisture content of less than 0.2%, without the need for heat conduction during the drying process, and without polluting zinc sulfate, which is difficult to achieve with conventional dryers.
Due to the fact that the material is heated both internally and externally, and the surface of the material is in direct contact with air. Therefore, the internal temperature of the material will be slightly higher than the surface temperature, so the moisture inside the material will migrate from the inside to the surface and then be discharged into the air.

2、 Main characteristics and advantages of microwave heating drying:
1. Heating quickly
Microwave heating is completely different from traditional heating methods. It is the process of making the heated material itself a heating element without the need for thermal conduction. Therefore, even materials with poor thermal conductivity can reach the heating temperature in a very short time.
2. Heating evenly
Regardless of the shape of each part of an object, microwave heating can uniformly penetrate electromagnetic waves both inside and outside the object, generating thermal energy. So the heating uniformity is good, and there will be no phenomenon of external focus or internal generation.
3. Energy saving and efficient
Due to the fact that substances containing moisture easily absorb microwaves and generate heat, there is almost no other loss except for a small amount of transmission loss. Therefore, it has high thermal efficiency and energy saving. It saves more than one-third of energy compared to infrared heating.
4. Mold prevention, sterilization, and preservation
Microwave heating has thermal and biological effects, which can sterilize and prevent mold at lower temperatures. Due to the fast heating speed and short time, it can maximize the preservation of the activity of materials and the vitamins, original color, and nutritional components in food.
5. Advanced technology and easy control
As long as the microwave power is controlled, immediate heating and termination can be achieved. The application of human-machine interface and PLC enables programmable automation control of heating processes and heating process specifications.
6. Safe and harmless
Due to the fact that microwave energy is controlled to operate in metal heating chambers and waveguides, microwave leakage is minimal, there is no radiation hazard or harmful gas emission, no waste heat or dust pollution is generated, and neither food nor the environment is polluted.
