High Frequency Electromagnetic Field Modeling and Experimental Validation of the Microwave Drying of Wheat Seeds
By
Progress In Electromagnetics Research B, Vol. 41, 419-439, 2012
Abstract
The aim of this study is to determine the effects of the thermal treatment with microwaves on the germination of wheat seeds, type Apache × Renan for different processing parameters. With the experimental data we intend to find out the optimum balance between applied energy and material humidity so that the material can be dried without its structure being adversely affected. From the analyze of experiments regarding wheat seeds drying with the aim of obtaining a quality product we mention that the best results are referring to the situation of using the microwave power of 0.3 W/g combined with hot air stream and having the measured temperature in the seed bed below the value of 75°C.
