Abstract

The granulated material is heated, at a temperature below its melting temperature, to a plastic condition. The granulate is subjected to the stages of partial crystallisation, drying and final crystallisation and subsequent homogenisation by direct contact with hot inert gases or heated air. The through of the granulate is directly controlled in all the stages by a metering unit at the dryer output or by a processing machine connected to the dryer.
