Abstract (en)
[origin: EP1847791A1] The method involves loading sludge (5) inside a tub spaced from walls of an enclosure (1) by a material inlet (8). Heated vapor is injected into the sludge by using a mixer (3) operating closer to a tub`s wall that is spaced with respect to a microwave source. The sludge is heated to the core by emission of microwaves (23) of frequencies comprised between 400 and 2450 mega Hertz in a direction of a tub (7). Water collected by condensation on walls of the enclosure is evacuated, via small openings, towards the bottom of the enclosure by using a valve (6) communicating with the exterior. An independent claim is also included for a device permitting to implement a method for drying sludge.
