  • Thermal Drying - an overview | ScienceDirect Topics

    Trevor Sparks, George Chase, in Filters and Filtration Handbook (Sixth Edition), 2016. 5.1.1.1 Dryer throughput. In many processes, a thermal drying step can be a bottleneck, limited by the amount of water that can be evaporated. Reducing the amount of moisture in the cake will give an increase in solids throughput. To take the above example, but in this case assume that the dryer throughput ...
