Odour Control in the Animal Feed Industry

Odour Control in the Animal Feed Industry

Your Problem

The animal feed industry has its roots in the way traditional millers ground grains centuries ago using wooden windmills. Nowadays, feed is produced for chickens and other poultry, as well as for cattle, pigs, and horses. There is a wide variety of feed and grains produced, with different raw materials (nutrients) applied in several compositions.

In this modern era, electric-driven pellet mills are used, and grains are cooled mainly in counterflow coolers. To remove dust from the cooling air, a baghouse filter is usually used, which meets current severe dust emission standards. After this, the air is eventually blown outside. Especially the cooling air of poultry feed and pig feed production should be deodorized to prevent complaints.

Initially, the animal feed industry built higher chimneys as a measure against odour nuisance. This did not always solve the problem sufficiently, especially because the tonnages of feed per factory were increasing significantly.

Our Solution

A factory usually has multiple pellet lines in service, with about 15,000 to 25,000 m³/h of cooling air per line. Aerox has developed specific solutions for this industry.

A compact Aerox-Injector can be installed per pellet line. Alternatively, airflows of different production lines can be joined together and treated with one compact Aerox-Injector. In practice, this can be up to four lines with a total airflow of up to 90,000 m³/h.

Since the Aerox-Injector can run on different capacities, unnecessary power consumption is prevented when not all pellet lines are in service. This benefits the environment and reduces operational costs.

Rothkötter, Germany

One of our first Aerox-Injector clients, Rothkötter in Germany, purchased two Aerox units for a brand-new factory. The company’s decision to invest in odour abatement technology was image-driven — its owners wanted to maintain a good relationship with the local population.

Aerox first supplied an Aerox-Injector to this company in 1998, before delivering two more in 2001. All three units still perform outstandingly. When the company later tested a competitor’s cold plasma solution, the results confirmed that Aerox-Injector remains the Best Available Technology (BAT) on the market.

The company subsequently purchased new Aerox-Injectors for their new production plant and one more for a pellet line in their existing factory. They now operate six Aerox units across two poultry feed factories.

Moy Park, United Kingdom

Moy Park, a major poultry feed producer in the UK, operates two pellet lines at one of its feedmills. Based on recommendations from AB Agri Feed Mill in Uffculme (which successfully treats two lines with a single compact Aerox-Injector), Moy Park installed Aerox technology to guarantee effective, complaint-free odour control.

Using Aerox allowed Moy Park to treat the cooling air from its pellet lines efficiently, reducing odour emissions and ensuring good relations with neighbours while keeping energy use economical.

Fransen Gerrits — The Netherlands

Fransen Gerrits, a feed producer in the Netherlands, applied Aerox solutions for odour control across their production lines. They installed Aerox-Injectors to manage combined cooling airflows from several pellet lines, achieving strong reductions in odour nuisance.

The flexible capacity of the Aerox-Injector let Fransen Gerrits adapt to variable production loads — treating only the air volume required at any given time. This resulted in reliable odour control, lower power consumption during partial production, and improved compliance with local environmental expectations.
