Paddle dryer for the Chemical industry
Salts, hydroxides and process cakes dried in an enclosed, corrosion-resistant system with optional solvent recovery.
- Typical feed
- Wet cake from filter press or centrifuge
- Heating
- Steam or thermic fluid
- Contact parts
- SS 316 / Duplex 2205
- Mode
- Atmospheric or vacuum, solvent recovery

The challenge
The Chemical drying problem
- ✕Sticky, corrosive cakes crust on hot surfaces
- ✕Solvent vapours must not escape
- ✕Dust and operator exposure in open dryers
With an AS Engineers paddle dryer
Chemical cakes are sticky, corrosive and sometimes hazardous – the material rotary and fluid-bed dryers struggle with.
Why a paddle dryer fits
- SS 316 or Duplex 2205 contact parts
- Indirect heating – no combustion-gas contamination
- Purged, enclosed design with solvent recovery
- Self-cleaning paddles stop crusting and cross-batch residue
Typical process
Wet cake from the filter or centrifuge enters the dryer; steam or thermic fluid controls temperature; vapours are condensed or scrubbed.

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.
