Hot air dryers

Non-hygroscopic materials retain moisture only on the surface. The presence of moisture during processing can compromise the final quality of the product.

A dryer consists of a fan that sends ambient air into a process chamber where it is heated to a set temperature. The resulting hot air passes into the drying vessel containing the material, circulating from bottom to top, where it heats the granules and removes surface moisture, vaporising it into the hot air stream.
