Encapsulation is one of the final steps of the manufacturing process and requires the final blended powder to be transferred into the encapsulation machine. Preventing product segregation, providing a consistent product feed-rate, and managing dust control are all common challenges with this process. Rheo offers several material handling packages for this process. A slewing Drum Inverter with a single or dual sided powder feed chute provides an operator friendly, semi-closed powder transfer system. An integrated Ventilation Sleeve provides local dust extraction at the transfer connection.

Drum Inverter
The Rheo Drum Inverter features a very robust and portable design that allows operators to lift and position drums above tall applications. Custom options on the Drum Inverter allow it to accommodate a wide variety of applications. A variety of compression cone designs are available to allow the Drum Inverter to be used with a range of drum diameters. The optional empty assist feature addresses the issues associated with powders trapped in the folds of the drum liner during inversion.
The Mobile Drum Inverter can accommodate a wide range of drum diameters and heights.
Ventilation Sleeve
The Rheo Ventilation Sleeve provides localized dust extraction to capture airborne dust and vapor. The full perimeter slot design provides 360 degrees of extraction to ensure that the required capture velocity is achieved across the entire opening of the Ventilation Sleeve. Each Ventilation Sleeve is engineered to interface with the equipment it serves. The Ventilation Sleeve can be offered as a standalone fixture or mounted on an articulating, height adjustable arm. These arms can be integrated with a portable cart or a wall mounted plate.
Several options are available to ensure the best solution for the application. These options include bag landing tables, bag disposal ports, integrated lids, custom adapter plates, and product grates.
Drum Cart with Integrated Weighing
Rheo Drum Carts allow drums to be easily moved from one location to another. Drum Carts are ideal for environments where GMP compliance is a priority. Integrated weighing allows for drums to be weighed while on the Drum Cart, eliminating the tedious step of loading a drum onto a scale. Stainless rollers are available to help facilitate the transfer of drums to and from pallets.
The load cells and readout are battery powered and capable of full wash-down. An integrated charger for the weighing system is included.
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.
