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
