Pneumatic Conveying and Dust Control System for Flour Mills - LEFILTER Solution

Product Introduction:

LEFILTER's flour mill dust control system is an integral part of the pneumatic conveying process, designed for hygiene, efficiency, and safety. We specialize in cyclone receivers and final polish filters that separate the flour product from the transport air. Our cyclones are designed for minimal product degradation and high separation efficiency. The final filtration stage typically employs food-grade, FDA-compliant polyester needle-felt filter cartridges with a smooth surface for easy cleaning. For areas with explosion risks (like filter receivers after grinders), we integrate full NFPA-compliant explosion protection, including explosion vents, isolation valves, and pressure-shock resistant construction. All surfaces in contact with product are smooth and accessible, designed to meet stringent food safety standards.

Application Area:

This system is deployed throughout wheat and rye flour mills, from grain intake to finished product loading. Dust is generated at virtually every stage: grain cleaning, tempering, breaking, sieving (sifting), and purification. Flour dust is highly combustible (Kst > 200 bar*m/s), creating a serious explosion hazard. Furthermore, uncontrolled dust leads to product loss, creates housekeeping nightmares, poses respiratory risks (including baker's asthma), and can attract pests. Effective dust control is therefore a critical component of safety, quality assurance, and profitability in milling.

Our Solution:

LEFILTER engineers understand the milling process. We design systems that balance effective dust capture with optimal product recovery. Our approach involves source capture at key generation points like sieves and conveyors, connected via a network of ducts to central collectors. For pneumatic transfer lines, we provide high-efficiency filter receivers that act as both product separators and vent filters. Our explosion protection engineering ensures safety in designated zones. We focus on designing systems that are easy to inspect and clean, supporting your food safety programs like HACCP. The result is a cleaner, safer mill environment, reduced product giveaway, and assured compliance with health, safety, and environmental regulations.
