The challenge
The Plastics drying problem
- ✕Dust and fines from high-shear dryers
- ✕Thermal degradation and yellowing
- ✕Grade changeovers and cleaning
With an AS Engineers paddle dryer
Polymers need uniform drying with tight temperature control and minimal dust.
Why a paddle dryer fits
- Low-speed paddles minimise attrition and dusting
- Precise temperature through indirect heating
- Optional closed loop with inert purge
- Easy cleaning for grade changeovers
Typical process
Wet chips or cake are dried to specification and discharged to bagging or silo.

Inside the dryer
From sticky cake to dry granules – one continuous pass
Wet cake
Dark, heavy, sticky lumps enter the hopper.
Plastic phase
Heat softens it; paddles knead and stretch.
Shearing phase
Paddles shear the mass into crumbs.
Dry granules + powder
Free-flowing granules and fines discharge.
Illustrative moisture along the dryer. Dried output goes to fuel · cement kilns · bricks · agriculture.
