Vacuum Conveyance System

[Patent Pending]

The Rheo Vacuum Conveyance System [Patent Pending] provides a safe, efficient, and contained means for transferring material using a vacuum source instead of relying on gravity. The Vacuum Conveyance System is ideal for transferring highly toxic or potentially explosive powders that are present in the pharmaceutical, food, and chemical industries.

 

Safety: Creates a closed transfer system that can achieve containment levels of less than 1 μg/m3. For potentially explosive products, nitrogen can be used to ensure the product is flooded with nitrogen before being discharged to the receiving vessel.

Efficiency: Continuously transfer material without operator involvement, which can eliminate one entire step of the manual material transfer process. Control systems allow for optimization of flow rates for various materials and conditions.

Reliability: Automated controls ensure a repeatable process.

Clean in Place Design

The Rheo Vacuum Conveyance System has an integrated full-flush CIP system in the receiver head and can additionally be equipped with a retractable spray device to ensure coverage.


Product Testing

Rheo has extensive experience with the vacuum conveyance of numerous types of bulk solids, however every product is unique and needs to be tested using application-specific conditions to confirm the transfer rate.

  • Process verification testing at Rheo provides proof of concept testing for new projects.
  • The Rheo Testing Center has many powders on-hand in inventory as well as a testing performance database for reference.
  • Multiple vacuum line configurations, diameters, lengths, and heights are set-up in our Testing Center for a wide range of testing options.
