Our solutions guarantee efficient filtration using food-grade materials and a design that facilitates cleaning, maintenance, and operational continuity. We understand the operational needs of the food industry, where controlling emissions is key to ensuring safety, hygiene, and regulatory compliance.
Our filtration systems adapt to the changing nature of dust, humidity variations, and the cleaning requirements typical of the sector, providing reliability without compromising process safety or product quality.
We create specific filtration systems to safeguard critical equipment in food processing, such as compressors, fans, and pneumatic systems. Our solutions are designed to minimize cross-contamination risk, allow quick cleaning, and comply with strict sanitary standards.
We design each model to match key parameters such as type of dust, working temperature, humidity or particle load, which allows us to guarantee efficiency and durability in our equipment.
Emission source
Typical particle size range (µm)
Main characteristics
Reception and milling of grains/cereals
10 – 500 µm
Organic dust, explosion risk; predominantly coarse fraction with respirable fines.
Mixing and dosing
20 – 200 µm
Heterogeneous dust; hygroscopic and occasionally corrosive (salt, mineral additives).
Drying and roasting (coffee, cocoa, cereals, etc.)
1 – 50 µm
Fine particles, combustion risk; possible presence of volatile corrosive compounds.
Sieving and packaging
2 – 100 µm
Fine, light dust with high respirable fraction; explosion risk from airborne suspension.
Pneumatic transport and conveyors
10 – 150 µm
Dust of variable density; tendency to stick due to moisture or grease.
Storage (silos, hoppers)
20 – 300 µm
Suspended organic dust, explosion risk (ATEX); high hygroscopicity.
Mainly fine dust from cereals, flours, sugars, spices, and other organic materials, which often have corrosive or hygroscopic properties and can vary in size and density.
Bag filters prevent particles from different processes or batches from mixing, maintaining product purity and ensuring food safety according to sanitary protocols.
They are applied in milling, drying, packaging, ingredient handling, and bulk product processing, where dust generation is significant and emission control is critical.
Filters are made with certified food-grade materials, with smooth surfaces and designs that facilitate periodic cleaning, preventing residue buildup and enabling disinfection.
Efficiency depends on the type and quality of the filter material, the design and frequency of the pulse cleaning system, environmental conditions such as temperature and humidity, and proper sizing according to the treated air volume.
With proper maintenance and optimal operating conditions, filter bags in food applications can last between 3 and 7 years, depending on dust abrasiveness and composition.
Food safety regulations such as FDA, EC 1935/2004, and certifications for food-contact materials are essential, along with compliance with environmental regulations on atmospheric emissions.
