Abstract
PURPOSE: To simplify washing when a lot is changed and to make lavor-saving possible, by providing rotary sealing plates between the both ends of a heating drum and the wall of a vacuum chamber, and providing a reflection board along the wall between said plates.
CONSTITUTION: A polycondensed resin chip is heated with agitation in the absence of oxygen in pretreatment chamber 1, in which vacuum is broken with N2 gas, by alternately opening and closing vacuum valves at the top and bottom ends, advancing crystallization of the surface layer. After thus preventing the occurrence of snagging during subsequent heating at a high temperature, it is intermittently dropped into high-vacuum container 2, and supplied from the bottom thereof to one end of drum 5 revolving in a high-temperature, high-vacuum chamber, by screw feeder 3. After vacuum drying and solid-phase polymerization proceed, by rotation, agitation and heating by means of conveyer 6, it is dropped from the other end of the drum into high-vacuum discharge hopper 7, and intermittently discharged into normal-pressure hopper 9, after cooled in N2 gas with agitation in after-treatment chamber 8. The product is prevented from contamination by providing the rotary sealing plate 10, between the both ends of the heating drum 5 and the wall of the vacuum chamber 4.
