Abstract: The invention relates to an electric machine (fixed, mobile or portable) suitable to the physical, dynamic, continuous conditioning of materials having the ability to absorb electromagnetic radiation, which have the need to be treated through the irradiation of UV or IR, even without entering into contact with the machine and this also through the vacuum. The invention mainly uses the Lambert and Stefan-Boltzmann postulates, or rather the physical assumptions of the transmission of energy by radiation and in particular the concentration and the emission proximity of energy between transmitter and receiver (which varies with the square of the distance) and the emission intensity (which varies with the fourth power of the temperature). The extremely small distances between transmitter and receiver of electromagnetic energy and the cylindrical shape and concentric electromagnetic emission source (reflected from the outside towards the centre) are the main essence and novelty of the invention.
