AIR QUALITY INTERVENTION STRATEGIES IN THE PROCESSING PLANT: A SYSTEMS APPROACH

摘要

The air handling system is an integral part of the poultry processing plant. When changes are being made to a processing plant one needs to consider the impact of these changes on the air handling system. The design of a proper air handling system for adequate control of moisture, dust, and microorganisms is critical for worker health, product safety, and overall plant performance. The current trend in red meat and poultry processing plant ventilation is toward positive pressure. Recent conversations with poultry processors suggest that many are considering and some are converting their processing facilities from negative pressure to positive pressure air handling systems because of the better control over air distribution, air infiltration, and the ability to filter make-up air. As processors continue with HACCP and focus on food safety, air handling is going to become a higher priority and positive pressure air handling systems offer greater flexibility than negative ventilation systems and can reduce potential food safety hazards that might occur as a result of the air handling system.
