The Importance of Clean Air
Food and pharmaceutical producers today require hygienics and sanitation in their manufacturing process to help ensure safety and quality in the fi nished product. A major part of these processing environments is the air; its temperature, moisture, fi ltration and maintaining positive room pressure.
The air is in contact with the products, equipment and employees. Even a small amount of unconditioned air can adversely affect the processing room and may interrupt production, costing the manufacturer time and money. Proper sizing, features and construction are all key considerations when choosing a hygienic air handling system.
Why Use Hygienic Air Handlers?
The goals of today’s food processing facilities are simple: maximize production capacities and profi t potential while supplying safe products to consumers. However, recent product recalls and illnesses linked to unsafe food products have created several challenges for the entire food industry. Government regulations and programs such as Hazard Analysis and Critical Control Points (HACCP) and the Food Safety Modernization Act (FSMA) are designed to help ensure that food processing plants are following the necessary guidelines to provide consumers with the safest products possible.
The integrity of safe food products can be related to proper airfl ow, room pressurization, balance and maintaining appropriate room conditions.
What Does A Hygienic Air Handler Do?
During production, the unit utilizes a combination of return air and outside air to satisfy room conditions. When the process room stops production and goes into sanitation cycle, the PHOENIX™ PH unit is then switched to “clean-up” mode, introducing 100% outside air into the room.
Depending upon the ambient conditions, fresh air may require heating to maximize drying of the process room.
