​COMAS is one of the pioneers of air drying tobacco using towers, having started supplying this type of equipment in the early 70's, with the original puffing plants.
Over the years, this wealth of experience has enabled us to develop and supply the latest advanced air drying technology.

Our tower design uses a compact tower height to minimise the need to access components at high level, with most of our drying towers being less than 7.0m tall.
The COMAS tower type CTD, is a closed re-circulation loop air dryer that provides accelerated drying, using superheated steam in a low oxygen environment.
The process gas is heated using an indirect heat exchanger of tubular construction, heated in turn by a gas/oil fired burner.
After the product has been dried, it is discharged through a tangential separator fitted with a rotary air​lock, allowing the product to be handled gently at discharge, by not having to pass through a cyclone.

The COMAS tower dryers can process flows from 500 - 10,000 kg/h of Cut Lamina and 500 - 4,000 kg/h of CRS​.
