Experimental 60 equipments, used for example for dielectric heating, drying and polymerization. The cooling system of the microwave oven is based on recirculation of air. This is inhaled from a fan, placed at the bottom of the oven, and then blowed on electric resistances, and therefore put in the cavity, through a pipe, positioned at the begin of microwave region on the top of the cavity. In this way the temperature can be maintained at the value selected by the user. The temperature control is devolved to a main PLC (Programmable Logic Controller). The PLC manages the electric resistances according to the signal received from temperature probes inserted in the inhaling system, and the value set by the user. In Figure 2.4, 2.5, 2.6 and 2.7 are presented some pictures of the microwave oven used for performing the microwave experiments. Figure 2.4: Front oven view. Two schemes are reported in Figures 2.8 and 2.9, the first showing the microwave distribution inside the cavity and the second illustrating the position of the magnetron. 60
