Bi.Elle: applications for all the fields
In the last 10 years the use of microwaves has encountered lots of industrial application fields in the processes that concern the warming-up of materials, whose conventional mechanisms (conduction, convection and irradiation) do not allow an effective, fast and homogeneous rise of temperature. Compared to most of conduction heating methods by means of fluid or contact with hot solid bodies or infra-red irradiation, that are transmitted from the items' surface to their inside, the broadly recognized main advantages of this technology are the immediate energy penetration together with highest rapidity of warming-up, the instantaneous activation and disactivation, the exceptional heating selectability of different materials also when they are in contact, the remarkable energetic spare because there is no need to warm-up other material besides the required one (such as for example the traditional oven walls).
