Fluid Bed Drying technology is a common method for the wet granulation process. Loading and unloading the large fluid bed dryer bowl can introduce many material handling challenges. Rheo offers containment and material handling solutions for filling the fluid bed dryer. The Vacuum Transfer Station with an integrated weighing system allows the operator to easily transfer the powders in an contained process. The system uses the fluid bed dryer vacuum system as the conveyance mechanism to draw the powder for the vacuum hopper.

Vacuum Transfer Station
The portable Rheo Vacuum Transfer Station features a small footprint that optimizes ergonomics and the functional requirements of a vacuum transfer system. The integrated Drum Tipper and vacuum hopper eliminate the ergonomic and exposure issues associated with open manway charging. The Vacuum Transfer Station can be configured to achieve containment levels of less than 1 μg/m³.
This Vacuum Transfer Station can utilize the evacuated vessel or PTS pump to carry out the powder transfer. Nitrogen inertion can also be achieved during the vacuum transfer of powders.
Air Filtration Unit (Supporting Product)
Rheo offers a complete line of portable and stationary Air Filtration Units that provide a local HEPA filtration device to serve Local Exhaust Ventilation (LEV) systems. The Rheo Air Filtration Unit is designed to meet the utility requirements of multiple Rheo Ventilation Sleeves; it is also a good fit for any application with similar extraction utility requirements.
Each system is configured to comply with international electrical standards. The GMP compliant design features a small footprint and noise rating of 76 dBa. Safe Change filters and activated carbon filters for VOC’s are also available.
Rheo Air Filtration Units are a cost effective alternative to upgrading house exhaust systems that have become over utilized or where there is a need to prevent the contamination of the house exhaust system ducting.
Vacuum Conveyance System (Supporting Product)
The Rheo Vacuum Conveyance System [VCS] provides a safe, efficient, and contained means for transferring material using a vacuum source instead of relying on gravity. The VCS is ideal for transferring highly toxic or potentially explosive powders that are present in the pharmaceutical, food, and chemical industries. Safety, containment, and productivity are all addressed with this simple to use machine.
