Flour dust
What is flour dust?
Flour dust is an almost invisible yet highly potent pollutant. Composed of tiny particles—measuring up to 10 micrometers—it primarily consists of carbohydrates and proteins. This makes it particularly challenging: its lightweight nature allows it to remain suspended in the air long after being released. Harmful dust clouds are mainly generated during flour processing, mixing, and sifting. And it doesn’t matter which type of flour is used—whether wheat, rye, or barley, flour dust is always present.
Is flour dust harmful to health?
Yes, flour dust is indeed harmful to health. Prolonged and frequent inhalation of large amounts can lead to serious health issues. The tiny particles penetrate deep into the airways, triggering allergies, chronic bronchitis, baker’s asthma, and severe eye and skin irritation. But there’s another danger: when flour dust accumulates in high concentrations, it can ignite and even cause an explosion. That’s why effective dust control is essential—to protect both employees and the entire company.
Symptoms of a flour allergy
A flour dust allergy develops gradually, but once it appears, it’s far from harmless. Common symptoms include itchy, red eyes, a persistent stuffy or runny nose, and a cough that can lead to shortness of breath. What makes it particularly deceptive is that symptoms often emerge hours later—sometimes even at night—long after leaving the workplace. Without treatment, a flour allergy can progress into baker’s asthma, a serious occupational disease. To detect it early and take effective action, an allergy test is essential.

Baker asthma treatment
Treatment for baker’s asthma focuses on relieving symptoms and improving quality of life. The most effective strategy is avoiding exposure to flour dust—those who don’t come into contact with it at work are not at risk. Workplace extraction systems significantly reduce dust levels, while respirators provide additional protection. Medically, baker’s asthma is treated similarly to regular asthma, with a focus on controlling airway inflammation. Some individuals also benefit from immunotherapy, which can lessen the severity of flour allergies over time. Comprehensive patient education helps individuals recognize symptoms early, manage them effectively, and practice proper breathing techniques.
Protect extraction systems against flour dust
Dust extraction systems are true all-rounders: they keep the air clean, protect employees, and ensure compliance with strict hygiene regulations. This is especially crucial in the food industry, such as bakeries and mills, where food safety and regulatory compliance are top priorities. But how do dust extraction systems actually work? The technology follows a multi-stage process that begins with dust capture. Extractor hoods or pipes collect dust directly at the source, and strong airflow transports it through the system. The airflow speed keeps particles suspended, preventing them from settling. In the filter unit, flour dust is separated from the air. The dust remains trapped inside the system, while the purified air is either recirculated into the workspace or safely released outside.
Benefits of flour dust extraction systems
- Reduces dust concentration in the air
- Improves air quality
- Protects against respiratory diseases and allergies
- Reduces the risk of dust explosions
- Helps to comply with legal limits and hygiene regulations
- Automated operation
- Customized solutions for all companies and sectors
Beware of flour dust explosions!
When a high concentration of flammable flour particles accumulates in an enclosed space and encounters an ignition source, it can trigger a devastating explosion. This process typically occurs in two stages: first, a small primary explosion disturbs the settled dust, creating a cloud of airborne particles. This is followed by a much more powerful secondary explosion, as the suspended dust ignites and spreads rapidly. Fortunately, effective protection is available. ATEX-certified extraction systems significantly reduce the risk of flour dust explosions. The ATEX guidelines mandate that all equipment and installations in explosive environments be explosion-proof. These extraction systems, constructed from stainless steel, feature explosion-proof components and electronics. By capturing dust directly at the source before it disperses, they maintain dust concentrations below critical levels—ensuring a safe workspace.
