Abstract

PURPOSE:To prevent the entrainment of content to the volatile matter, by fixing the sealing rotor of titled apparatus which removes the residual monomer etc. from thermoplastic resin and hollow cylinder porvided to the lower end of said rotor, to the rotating shaft. CONSTITUTION:Content is entered near the upper end of the stirring blade 3 of the main body 1 from the inlet mazzle 8. At this time, the content is made foamy by rapid flashing, because the pressure of the body 1 is reduced and form of the foamy content is broken by the thin film making action by the blade 3 and after that, the content is moved downward repeating refoaming and rebreaking of foam by the blade 3. Meanwhile, volatile matter in the content is evaporated and removed and then, the content having nearly no foam, is reached the lower end of the blade 3. Further, the content is taken out of system by the discharge screw 20 and the product is obtained. The content made foamy by entering into the body 1 from the nozzle 8, is not moved to the upper side of the body 1 nearly by the work effect of the sealing rotor 16.
