Drying characteristics of coal slime in forced draft tray dryer

Dec 10, 2021

The forced draft fans were mounted in two rows in the upper part of the drying plant, while the exhaust fans were installed on the front wall. The forced draft fans are designed to circulate the air inside the dryer in order to improve mass and heat exchange, whereas the exhaust fans are designed to expel humid air from inside the dryer

    Drying is a crucial step in the processing of algae as it influences the biomass quality and economy of the process. Characteristics of solar drying (SD), oven drying (OD), and freeze drying (FD) of marine Chlorella sp. were studied. To reach a final moisture content below 10% it took 24, 23 and 72 h for FD at −50 C, OD at 80 C and SD at 25–58 C, respectively
