co current rotary dryer

co current rotary dryer

Dec 11, 2018 The co-current rotary dryer usually is used to dry the material with surface water which is easy to be dried and evaporated into water vapor, and also it needs some shorter drying time. Here we takes sand as sample. For the water in the wet sand, it is surface water which is easier to be dried and evaporated into water vapor.

    Numerical modeling of a co current cascading rotary dryer

    Jul 01, 2016 Similar to the model developed by Thorpe (1972), the co-current rotary dryer is axially divided into n fixed control volumes of length L/n, where L is the total length of the dryer. A schematic of a control volume is shown in Fig. 1.In order to conduct steady state heat and mass balances on each section of the co-current dryer, the following assumptions were made:

    Co Current Vs. Counter Current Drying

    Disadvantages of the Co-Current Rotary Dryer Higher Exhaust Gas Temperatures. The primary disadvantage of the co-current design is that it is slightly less thermally efficient, because the exhaust gas can never be cooler than the temperature of the solids, requiring more energy to be spent on keeping the exhaust temperature up.

    co current drying method yeast advantages disadvantages

    The dryer can be divided into co-current and counter-current types, depending on the flow direction of the drying gas. Although the counter-current dryer can produce materials with a lower moisture content than that of the co-current dryer, while the biomass is dried, it could catch fire (Amos, 1999). Thus, this study used a co-current rotary ...
