- Gentle lifting flights maintain product movement within roughly the 4 o’clock to 8 o’clock positions of the drum
- Lifting flights impart no forward movement (viewed from this end drum at left turns counterclockwise)
- Product dwell time is controlled by slope angle that can be adjusted manually or by hydraulic lifting jack
- Helical exit flights auger product out of the drum at a consistent rate
- Drums are normally made of 304L stainless but can be ordered in 316L stainless when needed for extra corrosion resistance against salty products
