PURPOSE:To remove by discharging efficiently water contents out of an apparatus, by pressurizing or heating a viscose material in a kneading area to make temperature higher than ordinary and make inner water contents in easily evaporating state, and then by stopping the pressurization and heating, and by removing by sucking gaseous contents in the material. CONSTITUTION:A rubbery material led in an introducing part 2 is applied by forwarding thrust and simultaneously pressurized to raise its temperature at a kneading area where the pitches of a screw 6 are small. Then the rubbery material fed into an apparatus itself 3 is forwarded with received thrust in spiral direction by the screw 6 and mixing effect is improved by contacting with a protruding part 8b of a pin member 8 which protrudes inside. After passing the kneading area, the pitches of the screw 6 become larger to relieve pressurization and also gaseous contents are sucked from a suction hole 9' of a hollow bottle member 9 for suction at downstream side where gaseous contents have a tendency of retention. At the same time because the boiling point of water contents is lowered owing to the lowering of pressure at the surroundings, water contents in the rubbery material are evaporated and gasified, and removed by being discharged outside from the suction hole 9'. |
