Abstract

PURPOSE: To obtain a purified rubber-like material by an economical and easy operation, by flashing a pressurized and heated rubber-like material solution in a tank having a cooled wall surface, and scraping the solidified rubber-like material deposited on the wall surface to remove the solvent instantaneously.
CONSTITUTION: A rubber-like material solution containing a solvent is fed into a heater 16 by a solution feed pump 15, heated fully and then fed from a feed nozzle 2 to a tank body 1 having a peripheral cooling jacket 4 of a solvent removing apparatus 17. The solvent is separated from the solution instantaneously by the flash evaporation. Furthermore, the rubber-like material solidified and deposited on the inner wall cooled by a refrigerant in the jacket 4 of the tank body 1 is craped by titled scraping blades 9 around the rotating agitating blade 8 and taken out of an outlet 3 for the rubber-like material and further taken from an apparatus 18. The separated solvent vapor is then taken out of a solvent taking out nozzle 7 and recovered in a condenser 19.
