Material Transfer Station with Tray Drying

Tray Drying

The Rheo Material Transfer Station is a small footprint workstation that improves operator safety and efficiency during the material transfer and weighing process. The operator workstation with the integrated drum tipper provides a compact, GMP, ergonomic means of transferring material.

The Material Transfer Station with Rigid Glovebox Containment is designed for highly contained, closed transfers for highly toxic products and APIs. Containment levels of 1-0.01 µg/m3 can be achieved via the rigid glovebox.

Rheo has conducted performance verification tests on the Material Transfer Station. The tests showed excellent results for each of the different configurations tested. Copies of the executive summary, full reports, and supplemental documentation are available upon request.

Tray dryer technology is a long established drying process that requires a lot of tedious and potentially hazardous product handling. There are two challenging material handling processes associated with tray dryers, and Rheo offers a solution for both processes. The Material Transfer Station can be designed with the Tray Dryer package. This system provides a high level of containment for both the drum emptying (tray filling) process as well as the tray emptying (drum filling) process after the powder has been dried.


The Material Transfer Station with Rigid Glovebox Containment has several benefits when implemented in the manufacturing process:  

  • Ergonomic Product Transfer
  • Minimal Consumable Costs
  • Cleanability (WIP Sprayball)
  • Controlled Atmosphere
  • Easy Drum Docking (Inflatable Seals)
  • Portable Dispensing Suite
  • Containment (1-0.01 µg/m3)
  • Small Footprint

Drum Tipper:

integrated Drum Tipper with Powered Drum Slide for easy dispensing

Side Tables with Rollers:

allows trays to easily be rolled in and out of the glovebox.


designed to help ergonomically position the Material Transfer Station

Load Cells for Weighing:

integrated weighing with washdown load cells for cleanability.

Drum Support Module:

integrated wash-down rollers make it easy to slide drums in and out.


non-marking rigid or swivel casters for GMP compliance.

Rigid Glovebox:

environment can be controlled to the desired specifications, achieves containment levels to 1-0.01 µg/m3.

Controlled Environment

The rigid glovebox can be controlled by a programmable logic controller to monitor and maintain a safe operating environment within the glovebox. The operating conditions are customized to a specific application and automatically change based on what mode the glovebox is in. A touch-screen HMI is used to control the operating mode and to display the system conditions or give user prompts. Glovebox pressure and oxygen concentrations are the two primary operating conditions that are controlled. 

Integrated Weighing

The integrated weighing system provides a compact solution for the weighing and dispensing operation. The weighing module that holds the receiving container is isolated from the workstation to provide excellent weighing accuracy.


The typical integrated weighing system includes the following features:

  • 150 kg Weighing Capacity
  • Mettler Toledo IND570 or IND560X Readout
  • 4X Mettler Toledo Load Cells
  • Load Cell and Readout are Washdown Rated for Cleanability
  • Weigh Accuracy to +/- 50 grams
  • Can be Integrated with Computer, PLC, or Printer
  • High accuracy, low capacity options are available

The Rheo design library and fast track design services allow our team to efficiently tailor our products to meet the specific requirements of each application. During the design phase, the Rheo engineering team analyzes the application to develop a custom and comprehensive material handling solution. By using standard options as well as custom-designed features, a GMP operator-centric design can be achieved. Various 3rd party components such as mills, RTP’s, or HEPA/carbon filters are often integrated into Rheo equipment to provide a custom turnkey product or system of products.

Material Transfer Station by Rheo is engineered with operator centric design.

Operator Centric Design

By designing around an analysis of operator movements during the drum charging process, an unmatched level of safety, operating simplicity, and functionality is achieved. A drum can be raised, lowered, and tipped into the proper position by using a single hand or foot control. This approach to drum handling allows the operator to easily control the product flow during the entire charging process.  


All exposed surfaces on the Material Transfer Station can be fully washed-down for cleaning. Some configurations of the Material Transfer Station include WIP spray-ball systems to wash the product contact surfaces.
