    3.1 Rotary Dryers Rotary dryers potentially represent the oldest continuous and undoubtedly the most common high volume dryer used in industry, and it has evolved more adaptations of the technology than any other dryer classification. All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is

    The dryer senergy usemust also beseen in the context of the complete process and, indeed, of the site as a whole. One key tool is pinch analysis (Section 1.4.2), which shows the temperatures at which the dryer heat load is required and where heat can be recovered from the exhaust vapor, and places this in the context of the overall production
