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.

By using microwave energy we avoid the main disadvantage of the present technology for producing electric insulations of condenser type; this disadvantage is exposing the deposited insulation layers at supplementary thermal cycles, layers that had already been thermal treated. This fact results by comparing the temperature values of the insulation layers between which a layer of conductor paint has been introduced, the first stratus being thermal treated with microwaves in a previous intervention. Microwave thermal processing of the new deposited insulating layer emphasizes the electromagnetic screen role that the conductor paint layer has in limiting the dissipation zone of the microwave energy only in the superior isolation layer.
