1、 Overview of Microwave Drying Technology
Microwave drying is a drying technology that uses electromagnetic waves to directly act on water molecules inside materials, causing them to undergo thermal motion. Compared with traditional hot air drying, microwave drying has significant advantages such as uniform heating, fast speed, and low energy consumption. Its working principle is based on the penetration and selective heating characteristics of microwaves, which can achieve a rapid drying process from the inside out.
