Vacuum Dilute Phase Pneumatic Conveying
Vacuum dilute phase conveying is a great way to move powders when product degradation, abrasiveness, and segregation are not major concerns. Products are conveyed at higher velocities with higher air volumes and lower air pressures in a continuous or batch manner.
Some vacuum dilute phase convey system characteristics/options include:
-
Inlet air cooling/heating or dehumidification
-
Multiple destinations or multiple sources (divert valves and/or source selection valves)
-
Equipment to meter product into convey line - rotary airlock or feeder
-
Filter/receiver at destination to separate air and conveyed product - many configurations
-
Cyclone receivers to separate granular products, fines, and air
-
Discharge valve based on process requirements - butterfly valve, rotary airlock, slide gate
-
Positive displacement blowers, two or three lobe configurations available
-
Batch or continuous process based on process requirements
