Abstract: Drying is an energy intensive processes in cashew processing industry. High prizes of electricity and interrupted power supply affecting the production is the motivation for this research. The objective is to develop a solar dryer and check its feasibility to adapt in cashew drying. The end conditions of industrial drying are to bring the moisture content from initial ±13% to ±5% maintaining its color and taste. An electrical heater drying system is developed to find energy required to dry one kg of cashew kernel. A solar air heater developed replaces only electrical heater. Experimental results ensure drying within stipulated time of 6 hours and energy consumption of 255 kJ against 270 kJ and 251 kJ of electrical heater drying and industrial steam drying. Study suggests design is feasible to small and cottage industries. The energy savings up to 25,000 kJ per day for a batch of 100 kg is possible.
