Method for flash heat treatment of e.g. materials by microwave radiation, involves heating material by stirring material and pre-heated bed for predetermined time so that heat is transferred to material by conduction and convection

摘要

The method involves preheating, by microwave radiation, a material bed (L) permeable to microwave radiation in a rotating bowl (2), so as to bring the bed to predetermined flash heating temperature. A material to be treated (P) is introduced through an opening (4a) into the material bed as soon as the bed reaches the predetermined temperature. The material to be treated is heated by stirring the material and the bed for predetermined time so that heat is transferred to the material by conduction and convection from the bed and by microwave radiation, and the treated material is removed. An independent claim is also included for a device for flash heat treatment.
