Abstract

PURPOSE:To obtain products poor in thermal deterioration by a method wherein two kneaders are provided, water is poured there, kneaded and the water content is extracted out of the material at a vent part. CONSTITUTION:The material supplied from a material supply part 5 into a cylinder 11 is melted and stirred by screws 1, 2 , fed forward and reaches a kneading part 6. The material enters blind grooves at the kneading part 6 and passes through a clearance delta with the cylinder 11, a clearance l between a plate ring 9 and a disk body 10 and a clearance between plate rings 9 and gross particles are crushed and kneaded fully. Thermal degradation is prevented by reducing the temperature of the material which has passed the kneading part 6 and a small amount of water is poured from a water injection part 12 in order to raise kneading effect. Filler is diffused and kneaded in the same way as the material sent to the kneading part 7 and a small amount of water is injected from an injection port 13. The water content injected from a vent hole 14 is extracted from the material sent into the 2nd stage 4 and the material is exhausted from a material exhaust hole following the front head of the 2nd stage 4.
