Fluidized bed dryer

conductiongasair

For fine powders (or heat sensitive products) thermal supply brought by fluidization gas is very low due to low gas velocity (or low gas temperature). Therefore, the fluidized bed area would be quite important. Addition of internal immersed heat exchangers will reduce significantly the size of the equipment as most of the thermal balance will be achieved by conduction through these exchangers. Typical height of product layer will be between 600 to 2000 mm in order to allow integration of the immersed heat echangers. Depending on application, different types of exchangers are available (bundle of tubes, dimpled plates, etc.). Depending on customer’s requirements and applications, COMESSA can provide a complete process unit including ancillaries equipment such as : air preparation assemblies, dedusting units, automation, etc.
