Spiral Dryer

Small Components


ACI’s Spiral Drum Component Dryer is a compact and efficient drying system that allows for continuous in-line surface drying of small and/or light components. The system comprises a single helix rotating drum constructed from perforated stainless steel, mounted horizontally. Parts enter the drum via a simple chute whereupon they are exposed to a blower-driven air knife which is suspended in the centre of the drum.

How it works


The combination of the tumbling motion of the product, and the powerful, high velocity air stream produced by the air knife, means that emerging parts/components are dried both efficiently and effectively. Once parts/components have been dried they can simply be collected manually or passed onto another process.

The blower supplying the air knife system can be remotely sited or mounted directly on-top of the dryer itself.
