ABSTRACT:
Apparatus for continuous production of intumesced, expanded, puffed, or exfoliated particles. A rotatable processing table is driven by a speed controllable motor connected to rotate the table at a desired rotational rate. Particulate feeding means overlie the table for depositing the particles to be intumesced onto a first sector in the path of the upper surface of the processing table during rotation thereof. Heating means are mounted above and below the plane of the processing table at a second sector in the rotational path of same which is spaced from the first sector, and heat expand the particles during passage through the second sector. A scraper blade is mounted above the processing table at a third sector in the rotational path of the table which is spaced and downstream from the second sector. The bottom of the blade is in sliding contact with the rotating table, the blade being adapted to intercept the expanded particles advancing on the table surface from the second zone and move the particles toward the periphery of the table. A collector is positioned to one side of the processing table and beneath the end of the scraper blade remote from the table axis of rotation, for receiving the expanded particles as same are swept by the blade from the table.
