The pet food industry produces dry and ‘wet’ food for pets. The odour emission of a pet food factory can be high and likely leads to odour nuisance in the surrounding neighbourhood, badly influencing the image of the factory.
In the Fish feed process the product is usually conducted to the dryer through pneumatic transport, after which it falls out from the dryer into the cooler. Odour sources in this process are the flash- off of the extruder, transport air, dryer air and possibly also air from the cooler.
The amount of air per line that is emitted and should be deodorized depends amongst others of the type of dryers/coolers (vertical or horizontal), but also whether air is recycled from cooler to the dryer.
...In the late nineties, long before `Biodiesel` and `Bioethanol` were commonly known, Aerox already developed solutions to get rid of odours from oil seed processing! This industry gains oil and meal out of the seeds of grains, like soy or rapeseed / canola. The oil is used in feed and food industry, but nowadays also can be used to produce biodiesel or bioethanol.
The animal feed industry has its roots in the way traditional millers grinded the 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 applied and grains are cooled mainly in counterflow coolers. To remove dust from the used cooling...
During the processes in the aqua feed industry large air volumes are emitted containing a lot of smelly components. This can cause annoyance in the surrounding neighbourhood.
The animal feed industry produces a wide variety of feed and grains, applying different raw materials. Especially the cooling air of poultry and pig feed production should be deodorized to prevent complaints.
