Abstract
Three types of solar energy based dryers viz. solar cum electrical dryer, solar cum biomass dryer and solar tunnel dryer developed by Central Plantation Crops Research Institute were compared with reference to their Specific Fuel Consumption (SFC), Solar Collector Efficiency and cost ofdrying ofcoconut. These three dryers were selected because the shape and size of the drying chamber of all dryers were the same and capacity is 1500 coconuts (225 kg. copra) per batch. It was seen that SFC was better in the case of solar cum electrical dryer followed by solar tunnel dryer but efficiency of the solar collection was found to be the least in the case of solar tunnel dryer. Cost of drying was minimum for solar tunnel dryer and maximum for solar cum electrical dryer.
