Radiant-heat sterilization tunnels

Figure 3 is a roughly to scale comparison of the two main types of sterilizing tunnel in industrial use, radiant-heat sterilizing tunnels and the more recently developed laminar airflow (LAF) tunnel sterilizers. 

Radiant-heat sterilizing tunnels have had extremely wide usage in pharmaceutical manufacture. Infrared heaters, located in the roof of the tunnel, heat surfaces of product items passing through the tunnel and internal surfaces of the tunnel itself. The heat is then disseminated throughout the product items by...
