Seasoning and spice production uses compressed air for grinding, blending, filling and packaging. The powders are fine and aromatic, so the air must be clean, oil-free and dry to protect quality and food safety.
Key applications
- Grinding and milling controls
- Blending and batching systems
- Filling, capping and sealing
- Pneumatic conveying of powders
Air quality
Product-contact air must be oil-free and dry, because oil odours taint spices and moisture causes caking. Control air needs a low dew point for reliable operation of filling machines.
System design
Use oil-free compression with drying and filtration, separate product air from utility air, and manage the fine dust with heavy-duty intake filtration. Provide redundancy for continuous packing lines.
