Abstract
Apparatus for conditioning granules of plastic resin comprises a barrel having a hopper feed at its upper portion and a resin discharge at its lower portion to provide for gravitational flow of the granular resin through the barrel. The barrel periphery is perforated to permit passage of heated gases into the barrel and over the granular resin. A channel is defined centrally of the barrel and extends therealong to collect gases flowing over the resins and discharge such gases externally of the barrel.
