Microwave processing uses the thermal effect generated by microwave radiation to heat, dry, sterilize, and other processes on food or other substances. Common microwave equipment requirements for processed product materials include:

1. Electromagnetic wave absorption characteristics: The working principle of microwave equipment is that the electromagnetic wave energy generated by microwave radiation is absorbed by the material and converted into heat energy. Therefore, processed products need to have a certain ability to absorb electromagnetic waves. Generally speaking, foods with high water content, high salt content or specific additives are more likely to absorb microwave energy.

2. Transparency and reflectivity: Some materials have high transparency to microwaves, and microwave energy can pass through the material without being absorbed, making it impossible to heat effectively. Conversely, materials with higher reflectivity reflect microwave radiation, resulting in poor processing results. Therefore, when choosing a processed product, its transparency and reflectivity need to be considered.

3. Thermal conductivity: During microwave processing, heat is usually conducted outward from the inside of the material. Therefore, the thermal conductivity of the processed product will also have an impact on the processing effect. Materials with better thermal conductivity can conduct heat more evenly and achieve a more uniform heating effect.

4. Safety: Certain materials may create the risk of fire or explosion, or release harmful gases under microwave radiation. Therefore, processed products must be microwave-safe materials that do not cause safety issues.

Different types of microwave equipment may have different requirements for the materials of processed products. Before using microwave equipment for processing, you should carefully read the equipment's operating manual and related instructions to understand the equipment's specific requirements for the material of the processed product, and operate according to the actual situation.
