Food products can be corrosive or not, but for processing in the food industry, the materials of the equipment must be made of corrosion-resistant stainless steel 304#. Microwave drying and sterilization equipment not only performs drying but also includes sterilization features. Microwave is a thermal conversion of electromagnetic energy, typically with wavelengths between 1mm to 1m, and only polar molecules within the material absorb microwave energy.

After absorbing microwave energy, polar molecules vibrate and rub against each other at a frequency of 24.5 billion times per second, generating heat that evaporates moisture to achieve the drying effect.
