Tofu and soy processing uses compressed air for grinding, pressing, forming, filling and packaging, with air frequently contacting the product. Hygiene is essential, and the system must be oil-free and dry.
Key applications
- Grinding and extraction controls
- Pressing and forming systems
- Filling, capping and sealing
- Packaging and palletising
Air quality
Product-contact air must be ISO 8573-1 Class 0 oil-free, with drying to prevent moisture issues. Control air needs a low dew point for reliable operation of filling and pressing machines.
System design
Use oil-free compression with drying and filtration, design for washdown, and provide redundancy for continuous processing and packing lines.
