ABSTRACT:
The invention provides an apparatus for continuously and efficiently treating volume-reduced polystyrene resin in gel state, thereby removing solvent and recovering resin. A volume-reduced gel-state polystyrene resin is heated in the separation/recovery apparatus under ambient pressure or reduced pressure, for removal of solvent and recovery of resin. The apparatus includes an apparatus main unit10having at the top of the unit a solvent-recovering section for continuously recovering evaporated solvent and having at the bottom of the unit a resin-recovering section for recovering the solvent-removed resin; a heating medium flow pipe20provided inside the apparatus main unit10for allowing flow of a heating medium inside the pipe; a gel-state resin-feeding means14for feeding the volume-reduced polystyrene resin in gel-state such that the resin is brought into contact with the heating medium flow pipe20; a resin-holding section13provided in the bottom of the apparatus main unit10for holding the resin flowed down to the member after contact with the heating medium flow pipe20; a heating means25for heating the resin held in the resin-holding section13; and a stirring means26for stirring the resin contained in the resin-holding section.
