Drying system for flammable loose material - has conveyor carrying material through oven using microwaves to dry material and has vacuum system

摘要

The drying system has a conveyor conveying the material through a drying oven. The oven uses microwaves to dry the material. The frequency of the modulated microwave radiation depends on the molecular structure of the material. The conveyor conveys the materials at different speeds through the microwave field. The oven is fitted with a vacuum system that allows drying to occur at pressures below atmospheric. The vacuum system may also be filled with an inert gas (or another gas) so that drying occurs in an inert atmosphere.
