Sun drying is still the most common method used to preserve agricultural products in most tropical and subtropical countries. Some of the problems associated with open-air sun drying can be solved through the use of a solar dryer who comprises of collector, a drying chamber and sometimes a chimney.

Dryers have been developed and used to dry agricultural products in order to improve shelf life. Most of these either use an expensive source of energy such as electricity or a combination of solar energy and some other form of energy.
