Abstract
A compact dedusting apparatus induces air flow through the housing by a vacuum generator mounted within the housing. The discharge of dust and debris can be passed through a conduit to a remote location without losing air flow velocity to facilitate the use of the compact dedusting apparatus within a clean room. The metering device is formed from stainless steel and mounted on a spring-loaded mounting plate to permit vertical movement of the metering device when a jam of the particulate material is encountered. The metering device can be driven by a low torque stepper motor operable at selectively variable speeds to control the flow rate of the particulate material. The discharge transition is formed with an enlarged cross-sectional area compared to the shape of the Venturi zone so that carryover pellets can be returned to the product flow instead of being lost with the dirty air discharge.
