Abstract

Disclosed is a process for cleaning feathers in a cyclone, wherein feathers are introduced into the interior of a tubular-shaped cyclone in a tangential direction thereof, so that a swirl motion of feathers can be generated in the cyclone together with the downward movement of feathers toward the bottom of the cyclone. A flow of ionized air from compressed air nozzles provided with high voltage electrodes is discharged onto the feathers in a direction transverse to that of the swirl motion. A turbulent flow is created in the cyclone, thereby permitting the feathers to be effectively opened. The impurities attached to the feathers are thus separated therefrom. Thereafter, purified feathers are exhausted out of the cyclone. Ozone generated by the corona discharge in the high voltage electrodes causes the feathers to be sterilized, deodorized and decolorized.
