EXTRUDER HOOD FOR PNEUMATIC CONVEYING SYSTEM

摘要

An extruder hood (10) configured to operate in a steady-state configuration and a non-steady-state configuration. The extruder hood (10) comprises an air inlet (18), an extruder hood outlet (20), and an extruder discharge zone (14) within an interior space of the extruder hood (10), with the extruder discharge zone (14) configured to receive extruded material. In the steady-state configuration, the extruder hood (10) is configured to direct air received from the air inlet (18) across the extruder discharge zone (14) to cause extruded material to be ejected from the extruder hood (10) via the extruder hood outlet (20). In the non-steady-state configuration, the extruder hood (10) is configured to direct air received from the air inlet (18) out of the extruder hood (10) via the extruder outlet (20) without being directed across the extruder discharge zone (14).
