Whether transferring to intermediate containers or to process equipment on the floor below, the gravity chute is a simple method for connecting a vertically oriented process.
The Bulk Bag Unloading Station: Paddles and Spout Clamp with Gravity Chute configuration offers the following benefits:
Tilt paddles are 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.
The gravity chute is the simplest method for transferring powders to receiving vessels directly below the system.
Fully Automated System
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.
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.
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.
Crushers, mills, or screeners can be easily integrated in-line to help with material flow and to reduce a process step.
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.
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.
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.
