Paper Abstract

Microwaves of 2450 MHz have been attracting attention from researchers of various fields. The most distinguished characteristics of microwave from conventional heating are volumetric and selectivity. Due to these characteristics, when combined with convective air, microwave-assisted drying can greatly reduce drying time and energy usage to achieve certain moisture content. These characteristics also make it possible to combine this highly efficient heating method with vacuum drying by passing the energy through a microwave-transparent vacuum chamber. Microwaves also have various applications in chemistry such as extraction of natural products from plant materials and microwave-assisted synthesis. In this paper, the work conducted in our lab on the applications of microwave energy in agriculture and chemistry is briefly reviewed.
