Dehydrated food production uses compressed air for drying, conveying, milling and packaging. The product is hygroscopic and sensitive to moisture, so the air system must be dry and oil-free.
Key applications
- Drying and cooling systems
- Pneumatic conveying of product
- Milling and sizing controls
- Bag filling and sealing
Air quality
Product-contact air must be oil-free and very dry to prevent moisture pickup and caking. Control air needs a low dew point for reliable operation of milling and packaging machines.
System design
Use oil-free compression with adsorption drying and filtration, separate product air from utility air, and provide redundancy for continuous drying and packing lines. Manage the dusty environment with heavy-duty filtration.
