Using a desiccant-based dryer, the drying chamber is tested in the heat transfer laboratory, Faculty of Engineering, Dayalbagh educational institute, Agra. Experiments are carried out to analyze the effect of heat on the drying maize at a different time and different drying trays positions. After harvesting, drying is an indispensable process for extraction of moisture content of grain production and improving overall performance for better outcomes. In India, sun drying is the main drying method used by farmers for drying their crop grain yield. The desiccant dryer is used for dehumidification of maize to remove moisture contents. The present research work emphasizes to analyze dehumidification on maize in the drying chamber at different time interval by using a thermal camera. A thermal camera is used to find the drying rate and performance evaluation of maize. Performance of dehumidifier is also correlated with the heat parameters. Thermal imaging gives a realistic and deeper view of grain drying. The efficiency was calculated to be 76.45% using desiccant drying.
