Drying is one of the major problems in Postharvest Operation. The traditional method of drying (sun drying) is weather dependent and unhygienic as affecting food storage. Bio-mass dryer was designed, fabricated and tested for performance as a solution to drying of Agricultural Produce. The dryer consist of the following operating component parts: a cabinet, blower, tray, heating element, temperature controller, Light Emitting Diode (LED) screen and switch. The factors considered in the study, using groundnut, was weight (50g, 100g and 150g), temperature (550C, 600C and 650C) and each were replicated 3 times. The results show that temperature of 600C and 650C favors the drying of the three weights than temperature of 550C. The time taken for each sample at different weight and temperature differs. Hence, the higher the temperature the lesser the time taken for the groundnut to dry, the higher the weight the higher the time taken for the groundnut to dry.
