Abstract
An extrusion system () includes at least one sensor () to detect localized presence of oil () on an exterior surface () or skin of wet extrudate material (e.g., ceramic material having a honeycomb cross-sectional shape), and at least one infrared emitting device () configured to impinge infrared emissions on at least a portion of the exterior surface responsive to one or more sensor signals. Localized impingement of infrared emissions may reduce presence of oil streaks () without undue differential drying of the extrudate skin (), and avoid surface fissures that would otherwise result in fired ceramic bodies. Separately controllable infrared emitters (), or at least one controllable infrared blocking or redirecting element (), may be used to impinge infrared emissions on selected areas. A humidification section () arranged downstream of infrared emitters () may be used to at least partially rehydrate the wet extrudate material, if necessary.
