microwave vacuum dryer

Introduction

A microwave vacuum dryer is a specialized type of drying equipment that combines microwave radiation with a vacuum environment to dry materials quickly and efficiently. This technology is particularly useful for drying heat-sensitive materials or those that require gentle processing to preserve their quality, such as food products, pharmaceuticals, and herbs.

Working principles of microwave vacuum dryer?

The principle of vacuum microwave dryer is a new drying method that combines microwave heating technology and vacuum technology. Its working principle is as follows:
Principle of microwave dielectric loss: Microwave is a penetrating electromagnetic wave that can be absorbed by polar molecules such as water molecules. Under the action of microwaves, water molecules in the material will swing and collide rapidly with changes in the electric field, thereby generating heat energy.
Simultaneous internal and external heating: Since microwaves can penetrate the material, the inside and outside of the material can be heated at the same time. This heating method does not require heat conduction, so the heating speed is very fast and can significantly shorten the drying time.
Advantages of a vacuum environment: In a vacuum state, the boiling point of water is reduced, which means that water can evaporate at a lower temperature, so that the drying process can be carried out at a lower drying temperature, which can avoid the material being damaged by high temperatures. damage.
