inlet air temperature inlet air velocity drum drive speed feed rate relative humidity of air and feed drive speed on the specific heat transfer coefficient and heat load during drying of fermented ground cassava in a rotary dryer experimentally It is shown that inlet air temperature inlet air velocity
air velocity used is a function of particle size and particle density The particle size distribution of the 2 outlet stream is almost identical to that of the inlet due to air cushioning between the particles While fluidized bed dryers have many advantages when used in continuous operation there are special 6 7
