The present invention relates to an apparatus and method for processing reusable fuel wherein the apparatus comprises a support body and a plurality of augers disposed within the support body. The augers may be configured to rotate against a vapor flow to clean carbon char from vapors comprising condensable and non-condensable hydrocarbons. A drive system may be connected to drive and control the plurality of augers. An exhaust system is connected to the support body. A gearbox housing is connected to the exhaust system, wherein the drive system is accommodated in the gearbox housing. A ventilation system is disposed within the gearbox housing. Additionally, a thermal expansion system may be connected to the support body.
