Wurster coating system for fine powders and pellets
When working with fine powders or small pellets in industries such as pharmaceuticals or food processing, achieving uniform, high-quality coatings can be challenging. Problems like agglomeration and inefficient coating times may arise, requiring an advanced solution to optimize the coating process.
Enhance coating quality and minimize agglomeration
The Wurster Accelerator from Freund is a sophisticated coating system designed for the efficient coating of fine powders (~10 microns) to small pellets (2-3 mm). This system utilizes a patented processing insert that fits into a fluid bed processor. The key feature of this system is the use of compressed air to divert the product away from the spray nozzle tip, optimizing product movement through the spray zone. This minimizes agglomeration and improves both coating quality and coating times. The increased atomization volume from the accelerator spray gun enables faster solution application rates while ensuring proper atomization. Freund’s specially designed perforated plate further enhances particle movement through the spray zone, leading to consistent and efficient coatings.
Benefits
- Minimized agglomeration for uniform coatings
- Faster coating application rates
