One way to improve the drying capacity is by using multilevel drying equipment system and fuel energy. The use of multilevel dryer in the drying chamber particularly remains divergent temperature. In this regard, a non-uniform drying air temperature correspondingly decreases the drying quality. Large temperature variations can be overcome by inhibiting the rate at which hot air escapes from the drying chamber. Such formulated investigation can be performed by reducing the angle of the chimney roof. In this research-based paper, the researchers will therefore turn the attention towards the effect of the chimney roof angles on the temperature uniformity in the multi-stored drying chamber. Such drying machine is equipped with combustion chamber, start-up, hot gas flow, multi-stored drying chamber and exhaust chimney of residual hot air. The chimney roof tested varies on angles 15°, 25° and 35°, respectively. The findings disclosed that the angle of chimneys is 15° which results in a more uniform drying chamber temperature. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
