Caramalization during drum dryer

Only if dusty goods are produced during drying, small amounts of the solid material to be dried are removed with the exhaust air. Very often, however, film-like dry goods are produced during the drying of food products, which means that the extracted dryer vapors are practically dust-free

    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

    1. When processing fine materials, an indirect dryer avoids the risk of entrainment. When processing in a direct dryer, fine materials can become entrained in the drying air, and carried out to the baghouse. An indirect dryer avoids this issue because there is minimal drying air moving through the drum. 2. Less exhaust air treatment is required
