Abstract

Hot toner pellets are cooled and separated from the airstream output of a hot melt granulator, without attrition of the pellets, by the use of a cyclone separator to which internal vanes have been added to produce non-laminar airflow in the cyclone.

Toner Manufacture

Hot toner pellets are cooled and separated from the airstream output of a hot melt granulator, without attrition of the pellets, by the use of a cyclone separator to which internal vanes have been added to produce non-laminar airflow in the cyclone.

Hot melt granulator 10 issues its hot pellet output to pipe 11.

A blower 12 produces below atmospheric pressure in pipe 13, cyclone separator 14 and pipe 11, thus causing the hot pellets to flow to the separator. The separator includes one or more internal vanes 15 which operate to disrupt the airflow within the separator, converting the airflow to nonlaminar flow. As a result, the toner pellets are cooled and separated, to exit out of pipe 16. Exhaust air exits by way of pipe 17.
