Solar Dryer System

Solar dryers could be classified as direct or indirect types. The former involves directly exposing the material to the sun. While in the latter, the material is dried by circulating hot air over it without directly exposing the material to the sun. The merits of any solar dryer would depend upon the type and quantity of material to be dried.

Mechanical drying systems - IRRI Rice Knowledge Bank

Solar drying - latest drying technology that is able to simulate sun drying even during rainy conditions. This is done through: Solar bubble dryer - can be locally-built and used by smallholder farmers; Grain cooling - cools the grain to safe storage conditions instead of drying it, …

The main objective of th is study was to design and develop a solar hybrid copra drying technique suitable for small holders. Three components; solar collector, furnace and heat exchanger were evaluated separately. It was found that the efficiency of the drum type solar collector was only 4%. The drum shape drying chamber of coconut cups was designed as the solar collector as well.
