The pneumatic conveyors used in the food industry represent one of the most efficient solutions for moving powder and granular raw materials within production plants. The food industry in Brazil makes up a significant share of the country’s economy, with strict quality and sanitary control requirements — and pneumatic conveyors for the food industry emerge as a direct response to that scenario, combining total sealing, guaranteed hygiene, and excellent operating cost.

Pneumatic Conveyors for the Food Industry: How the System Works

The movement of raw materials, inputs, and supplies is one of the main operational challenges in the food industry. This process needs to be carried out with maximum efficiency to minimize waste and preserve product integrity at every stage of production.

The system of pneumatic conveyors for the food industry moves powdered or granular products through fully closed piping that’s isolated from the atmosphere. Driven by the airflow generated by a pump or compressor, the material moves from an origin point to its destination quickly, efficiently, and with minimal waste — without contact with the outside environment at any stage.

It’s this sealed operation that makes pneumatic conveyors the preferred choice for the food industry, especially in plants that need to comply with ANVISA Good Manufacturing Practices.

Why Choose Pneumatic Conveyors for the Food Industry

The system’s total sealing is the main advantage of pneumatic conveyors for the food industry. Because of this feature, cross-contamination is reduced to nearly zero — a critical requirement in plants that process food for human and animal consumption. Compared to mechanical conveying systems such as belts, screws, and elevators, pneumatic conveyors offer advantages across multiple operational dimensions.

Greater Hygiene and Cleanliness in the Food Industry

Just like the pharmaceutical industry, the food industry must meet strict hygiene and cleaning criteria. Pneumatic conveyors are 100% sealed, ensuring sensitive materials are transported with near-zero contamination risk. Because they have few moving parts and friction points, cleaning and sanitizing between product changeovers is simple and fast. The piping material can also be adapted for each application — ensuring suitability for different types of raw materials.

Less Material Waste

The sealed design of pneumatic conveyors for the food industry ensures that virtually all the material fed in at the inlet is available at the outlet — with no spills, buildup on equipment, or dirt on the factory floor. In processes involving high-value ingredients, this reduction in losses translates into direct financial gain and improves line yield.

Flexibility in Installation and Adaptation

The pneumatic conveying systems for the food industry can be designed for virtually any type of operation and plant layout. The design takes into account the quantity and type of material, the conveying distance, and the specific characteristics of the installation. This flexibility also allows for future adaptations: changes to the production line or product type can be accommodated without a full system replacement and without major costs.

Excellent Operating Cost-Benefit

The acquisition cost of pneumatic conveyors for the food industry is competitive compared to equivalent mechanical systems. Maintenance is comparatively simpler and cheaper, with fewer wear parts and less frequent unplanned downtime. The system also allows for full automation, being reliable and robust — boosting productivity and reducing dependence on operational labor.

Pneumatic Conveyors for the Food Industry: Dense Phase or Dilute Phase?

Choosing the right pneumatic conveying system for the food industry depends on the characteristics of the material being conveyed. For fragile, heat-sensitive, or high-value ingredients — such as proteins, probiotics, and additives — a dense phase system operates at lower speed with less risk of particle degradation. For robust granular materials such as flours, starches, and sugars, a dilute phase system offers simplicity and lower installation cost.
