Ribbon blending is a long established blending technology that creates many material handling challenges both in the loading and unloading process. Rheo offers a few customizable material handling packages for this process. The Vacuum Transfer Station package offers a portable vacuum transfer system that comes with an operator workstation and a portable lifter to lift and position the vacuum canister above the blender opening. A Ventilation Sleeve can be place on the top opening of blender for local dust extraction. The Mobile Ventilation Sleeve or portable Product Screener can be used to capture airborne dust during the emptying process of the blender. The vacuum system can also be used wand out any remaining residual powder that may not get fully removed during the emptying process.

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.
Custom Lifter
The Rheo manual lifter offers a cost effective, GMP handling device that is small footprint, and can be configured to lift and hold a wide variety of components.
Product Screener
The Rheo Product Screener provides a simple and GMP solution for security screening of powders. This design is ideal for the screening and repackaging of incoming raw materials as well as the point of discharge of blenders and dryers. With interchangeable screen sizes, a variable speed vibrator, and an integrated Rheo Ventilation Sleeve to capture dust, this device is a very versatile product for the important task of capturing foreign material.
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.
