What are the advantages of microwave equipment in the ceramic industry

Microwave ceramic drying equipment is mainly used in honeycomb ceramics, craft ceramics, high-voltage insulating ceramics, special ceramic powders, and electronic material powders for shaping and drying.

Conventional heating such as flame, hot air, electric heating, steam drying, etc. all use the principle of heat conduction to transfer heat from the outside of the heated object to the inside, and gradually increase the center temperature of the object, which is called external heating. It takes a certain time for the central part to reach the required temperature, and it takes longer for objects with poor thermal conductivity. This

1. Uniform drying Regardless of the shape of each part of the object, microwave drying can make the surface and the inside of the object evenly penetrate electromagnetic waves to generate heat. Therefore, the drying uniformity is good, and there will be no ingrown outer coke.

2. Rapid drying. Microwave drying is completely different from traditional drying methods. It is a process in which the dried material itself becomes a heating element without heat conduction. Therefore, even though it is a material with poor thermal conductivity, it can reach the drying temperature in a short time.

3. Anti-mold, sterilizing and fresh-keeping Microwave drying has thermal and biological effects, and can sterilize and prevent mildew at lower temperatures. Due to the fast drying speed and short time, it can preserve the activity of materials and the vitamins, original color and nutrients in food to a large extent.

4. High energy-saving efficiency. Because water-containing substances can easily absorb microwaves and generate heat, there is almost no other loss except a small amount of transmission loss. Therefore, the thermal efficiency is high and energy saving. It is more than 1/3 energy saving than infrared drying.

5. Safe and harmless. Because the microwave energy is controlled in the metal drying room and the wave guide, there is little leakage of microwave, no radiation hazard and harmful gas emission, no waste heat and dust pollution, and neither pollutes food nor Does not pollute the environment.
