Assembly for the continuous plasticising and filtration of materials

Lavit , Ê et al. December 5, 1995

Abstract

Assembly for the continuous plasticising and filtration of materials. The materials include polymers in the pasty, viscous, or molten state, visco-elastic products and proteoleaginous products. The assembly includes two modules, a plasticising module and a degassing and filtration module. A stator accommodates a floating screw and, in succession, a feed zone receiving the material to be plasticised, a homogenization zone, a degassing zone, a zone for the filtration of the non-molten material, and a zone for the outlet of the plasticised material. The portions of the stator which correspond to the various zones are provided with temperature regulating means, formed of a condenser, a heating device, and an annular chamber.
