Vacuum Hopper Process - Bulk Bag Unloading Station

BBUS - Vibrating Hopper and Spout Clamp with Vacuum Hopper

Introducing bulk solids to downstream processing can present a number of challenges; safe operator interface, powder containment, and process efficiency.

The Bulk Bag Unloading Station: Vibrating Hopper and Spout Clamp with Vacuum Hopper configuration offers the following benefits to address these challenges:

  • Allows materials to be transferred to various receiving vessels in remote locations.
  • Contained discharge from bulk bag.
  • Bulk Powder Transfer Rate : 100 kg/min
  • Requires buffer hopper and feeding device to achieve dosing accuracy less than +/- 1000 g


Vibrating Hopper and Spout Clamp

The vibrating hopper is a flow aid for non-free flowing powders. These are integrated in the simple manual spout clamp to provide a sealed, dust-free system during the powder transfer. A pinch valve is used in conjunction with the spout clamp to control powder flow.

Testing Center

Bulk powder handling can be a challenging process and there are many factors that lead to the optimal solution. We can handle the risk for you! Our Testing Center is equipped to test your materials, allowing us to design the best solution for your specific needs. We don’t just sell a product – we sell a solution.

Reach out to your Regional Sales Manager to discuss the testing of your next bulk powder handling project.


Rheo Testing Center

Bulk Bag Unloading Station - Customizable

Customizable

We will design custom configurations for your specific process. The Rheo design library allows 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.



Advanced Features

Bulk Bag Unloading Station - Integrated Weighing

Integrated Weighing

An automatic weighing system can be designed into the Bulk Bag Unloading Station configured as either a gain-in-weight (GIW) or a loss-in-weight (LIW) system. The SoliValve® or a pinch valve will automatically adjust to slow down and stop material flow to hit the target weight and to allow for partial bag unloading.


Bulk Bag Unloading Station - Inline Process Tooling

Inline Process Components

Crushers, mills, or screeners can be easily integrated in-line to help with material flow and to reduce a process step.


Bulk Bag Unloading Station - Spray Ball Device - CIP

CIP Spray Devices

Spray devices can be added to the product contact areas to ensure the system is fully Cleanable in Place (CIP). Our GMP retractable spray device fully retracts out of the product stream during powder transfer to ensure no blockage or retention and only extends during the cleaning process.

Water coverage of the CIP system can be validated (Riboflavin) during a Factory Acceptance Test.


Bulk Bag Unloading Station - Controls and Automation

Controls and Automation

Typical controls for the Bulk Bag Unloading Station include a touchscreen HMI that can be connected to your plantwide network. Simpler control options are also available.

Sensors can be integrated into the system to recognize when product flow has slowed or stopped which can trigger flow aids to turn on or warn the operator to intervene.


Pinch Valve for Bulk Bag Unloading Station

Pinch Valve

Controlling the flow of the bulk powder stream can be a challenge to the unloading process. The pinch valve is often used in conjunction with the spout clamp to control flow. It is designed with high powered cylinders to quickly and reliably cut-off the powder stream, capable of achieving dosing accuracy within +/- 1 kg.
