Food Processing & Grain Handling
Food processors and commercial flour mills rely on positive displacement air movers for dense-phase and dilute-phase pneumatic conveying of dry bulk powders like wheat flour, corn starch, refined sugar, cocoa, and animal feeds. Oil-free operation ensures that ingredients retain 100% purity and aroma.
Critical Engineering & Design Requirements
- Food-Safe Lubricants & Certified Seals: Food-grade oil used exclusively in external gear housings with certified food-contact lip seals.
- Minimal Heat Transfer: Controlled discharge air temperatures to prevent melting or caramelization of sugar crystals.
- Continuous Duty Cycle: Uninterrupted operation during harvesting and round-the-clock packaging cycles.
Engineering Selection Advice
When conveying heat-sensitive powders like milk powder or chocolate mix, incorporate an air-to-air aftercooler directly after the blower outlet to keep conveying temperatures below 40°C.
