Positioning and Transport
Accurate positioning and reliable transport are essential for uniform electron beam exposure. Different conveyor system designs, such as crawler conveyors and fixed-distance transport mechanisms, help maintain consistent distances between the electron beam source and the product. This consistency ensures uniform curing and sterilization across various product shapes and sizes.
The table below outlines common conveyor system designs used in electron beam processing facilities:
| Conveyor System Design | Product Type Description |
|---|---|
| Horizontal beam and carrier conveyance | Optimized for rectangular boxes, sensitive to excessive handling/flipping or higher temperatures. |
| Vertical beam and box/tray conveyance | Suitable for rectangular boxes and bagged or loose bulk products that can tolerate flipping or higher temperatures. |
| Reel to reel conveyance | Used for crosslinking cables or materials on rolls; few medical devices fall into this category. |
Technologies that ensure accurate positioning and transport include:
- Precision timing belt conveyors, which offer high accuracy and throughput.
- Pallet conveyors with lift-and-locate devices, minimizing lateral and axial movement.
- Lift-and-locate devices, which position pallets at designated stations for precise processing.
For example, a crawler conveyor with a concave frame allows for precise beam delivery, while a fixed-distance transport mechanism keeps the product at a consistent distance from the electron beam source. These features prevent uneven curing and improve overall process reliability.
Energy Efficiency
Energy efficiency remains a top priority in the design of any product conveyor system for electron beam processing. Modern systems incorporate high-efficiency motors, variable frequency drives, and low-friction components to reduce energy losses.
