Bulk Bag Unloading Station

The Rheo Bulk Bag Unloading Station is a modular, GMP system that is designed to work with a wide range of containers and processes. This system utilizes the Rheo Ventilation Sleeve technology to provide a high-containment, dust free, and easy to clean transfer system. From high-force conditioning to integrated nitrogen inerting options, the modular design of this unloading station can be configured to address a wide range of process challenges.

Safety: Reliably empty bulk bags without operator intervention.

Containment: Achieve various levels of containment; from simply containing visible dust using local exhaust ventilation to creating a completely closed transfer system using a split cone valve.

Productivity: Multiple flow aid options are available based on specific product properties to prevent bridging and ratholing and to increase the flow rate.

Vacuum transfer for bulk material transfer - Rheo Bulk Bag Unloading Station

Vacuum Transfer

The Vacuum Transfer Module allows for the bulk bag to be unloaded into a vacuum transfer system that conveys the product downstream to the receiving vessel.


Gravity chute transfers bulk material from Bulk Bag Unloading Station

Gravity Chute

The Gravity Chute Module allows this system to be configured so that the bulk bag can unload directly into a receiving vessel on the floor below.


Rheo Bulk Bag Unloading Station with Disperser System to allow for mixing and transferring of bulk materials

Disperser System

The Disperser System allows the Bulk Bag to unload into a disperser system that can mix the product with a solution and pump it directly to, or recirculate through, the receiving vessel.


Rheo Bulk Bag Unloading Station with screw conveyor, allows the product to be fed into the receiving vessel

Screw Conveyor

The Screw Conveyor Module allows the system to be configured with a screw conveyor system that can be used to feed the product into the receiving vessel.


Docking Systems and Discharge Aids

Rheo can conduct material testing with materials to meet the containment requirements and to optimize product throughput by customizing docking systems and discharge aids.

Docking Systems

  • Automated Docking System with SoliValve® 250
  • Bag Clamp with Extraction and Pinch Valve

Discharge Aids

SoliValve® 250

The SoliValve® 250 is an improved version of a Cone Valve system. It allows fully automatic and contained handling of big bags, containers, and drums. The SoliValve® 250 doses the material vertically from the storage container, allowing re-closing of partially empty vessels and changing to another ingredient without the need to empty the dosing hopper. The SoliValve® 250 can achieve containment levels of less than 100µg/m³ and can reach a dosing accuracy of +/- 20g.


Specifications

  • Control Interface: pushbutton controls, lift/lower of bulk bag, forward/aft of lifting trolley, lift/lower of bag tensioner system, on/off of rotary valve
  • Utilities: electric, compressed air, Nitrogen, dust extraction
  • Hoist Specifications: stainless steel clad GMP strap hoist on motorized trolley, options available for hazardous environments
  • Common Options: powered horizontal drive on lifting trolley, bag conditioning arms, rotary feed valve, vacuum hopper with fluidizer system, hazardous location configuration, WIP sprayball system, vacuum powered bag collapse system
