Method and apparatus for preferential heating of a material are based on exposing the material to high intensity, pulsed, non-ionising electromagnetic radiation. The method can destroy microorganisms, sterilize packaging, or sterilize moist food. An embodiment uses microwave radiation with pulse duration of less than 0.1 second with an average power of at least 1 kW to sterilize open-ended metal cans prior to packaging.
L'invention concerne un procédé et un dispositif permettant de chauffer préférentiellement un matériau, qui sont basés sur l'exposition de ce dernier à un rayonnement électromagnétique non ionisant pulsé de forte intensité. Ce procédé permet de détruire les micro-organismes, ainsi que de stériliser des emballages ou des aliments contenant de l'humidité. L'un des modes de réalisation utilise des micro-ondes ayant une durée d'impulsion inférieure à 0,1 seconde et une puissance moyenne d'au moins 1 kW pour stériliser, avant conditionnement, des boîtes métalliques ouvertes.
