Perfect Companion in Thailand produces dry pet food. The pet food is produced at several extruder lines. The company wanted to reduce its odour emission and therefore searched for more effective technologies than scrubbers.
Compact odour control system
The Thai company ordered an Aerox-Injector in 2011 to reduce the odours produced by one of the extruder lines. An important requirement was the installation being compact and efficient, for the factory having limited space. The process airflows coming from the counterflow dryer and cooler, together with pneumatic transport (from extruder to dryer), were cleaned by cyclones and then joined into one central duct. At the end we installed an Aerox-Injector to treat a total airflow of 60,000 m3/h.
Reducing pet food odours
After a thorough validation process determining the effect of the Aerox-Injection technology, Perfect Companion will decide upon the best approach to reduce the odours coming from all other extruder lines.
