    Abstract The aim of this work is to analyse different ways for controlling the final moisture content of a product dried on a drum dryer, and to reduce its unevenness in order to obtain a high-quality product and to increase dryer productivity. A new way to determine product moisture content by means of product temperature measurement is presented, which is convenient for a moving and low

    Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155 C.The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later

    The heatless desiccant dryer is the most expensive to operate as 15-20% of its rated flow capacity is consumed as purge air. The rotary drum dryer can lead to significant energy savings because of its unique design and controls. Even compared to a blower purge dryer, rotary drum dryers can save up to 50% of the lifecycle cost. Maintenance cost
