Abstract:
A cage type compactor and dryer apparatus for waste materials, comprising container means for containing the waste materials to be treated, means for compacting them, means for heating them, as well as means for discharging the water vapor generated by the heating step, characterised in that:said means for containing the waste materials to be treated comprise a cylinder shaped body (10) formed by longitudinal heating conduits (11) run through by a heat transfer fluid, such heating conduits being arranged according to the generatrix lines of said cylinder and in spaced apart relation and having the functions both to act as a bearing structure of the apparatus and to transfer heat from said heat transfer fluid to the waste materials to be treated contained therein,said heating conduits (11) are constrained together by means of retainer hoops (12), arranged under a pre-established mutual spacing in order to assure stability of the conduits forming said cylinder shaped body (1) under the radial generated by the waste materials being pressed as well as thermal gradients,said means for compacting the waste materials comprise two sturdy oppositely arranged and pressing plates (14), operating as mobile bases of said cylinder shaped body (10) and acting as pressing pistons,said means for discharging the water vapour generated by the heating of said waste materials are formed by the longitudinal slots estbalished between said heating conduits arranged according to the generatrix lines of cylinder shaped body (10) and in spaced apart relation.
