ABSTRACT:
In order to decrease or eliminate environmental contaminants which are added to fluent particulate matter removed from bulk material carriers by vacuum conveyor systems, the bulk material carrier is moved into an enclosure which can be closed off from the environment after the carrier is within the enclosure. Clean air containing a prescribed maximum number of particles above a given size floods the entire enclosure and air of even greater cleanliness is fed to each hatch of the material carrier to entrain the particulate matter in the clean air streams which pass though the bulk material under the influence of the vacuum conveyor.
