Extruder Hood

Extruder hoods are utilized in a negative airlift system which utilizes negative air pressure and is used for conveying product from an extruder to a dryer for further processing/packaging.

Advantages of a negative airlift system over mechanical transfer systems
• Partial/Flash pre-drying of the product
• Improved product expansion
• Steam and moisture from the extruder are contained within the conveying airstream
• Reduced opportunity for bacteria growth
