Hot air dryers
New Omap produces high performance ranges of hot air dryers HD series, mounted on machine, trolley mounted solutions HDC and floor standing large volume models HDS.
These dryers are particularly designed to dry non-hygroscopic thermoplastic materials in granules.
Non-hygroscopic materials retain the moisture only on the surface, trapping relatively small amount of humidity.
However any plastic transforming process in presence of humidity may seriously affect the final product quality.
Hot air drying consists of a fan which takes ambient air into an heating chamber to heat it up to a set temperature.
The hot process air is blown into a drying hopper, from the bottom to the top, passing by the granules thus heating them up and removing the moisture by stripping it off from granule surface and evaporating in the hot airstream.
The return air is filtered by a cartridge filter and then partially or totally exhausted in atmosphere by a bypass valve, thus optimizing drying cycle and improving energy saving.
