Abstract— Cardamom is a valuable spice that is obtained from the seeds of a continuing plant. India is the largest producer of small and large cardamom in the world with 54% share in world production followed by Kerala, Karnataka and Nepal and Bhutan. For long-duration storage of cardamom and in order to bring out its aroma, the fresh cardamom capsules (with 80%-85% moisture) has to be dried immediately after harvesting to bring down its moisture content to less than 10% through a drying  process. Still a primitive and inefficient (operating efficiency level of about 5%-15%) smoking method (using traditional method) is being used for drying of cardamom resulting in huge wastage of fuel wood (estimated 25,000 MT per year) and poor (burned and darkened) quality of dried cardamom capsules. An electric dryer is an improvement over the use of a wood fuelled fire and is the best choice for drying large quantities of cardamom, especially in places, where there is rainfall during the drying season. The alternate design of electricity based cardamom dryer, which is designed by some essential parts that is 1500W electric heater, air blower or electric fan for exchange the heat from heater to drying chamber and rotating type drying chamber and stepper motor. This paper gives a brief description of efforts made to obtain effective drying of small cardamom under different environmental conditions.
