ROOM DRYERS

When the quantity of products to b dried in a batch is large the use of room dryers is recommended. They are called room dryers because large barns with high roofs are converted into dryers. The operator of the dryer can walk into the room or enter the drying chamber (in the case of coconut dryers). The combustion chamber and the ducting assembly are conveniently laid at the base of the room. Heat is generated by the combustion of biomass on a grate in the combustion chamber and facilitating the movement of hot gases through the duct pipes. The material of construction of the ducting is varied depending on the expected temperature of the flue gas to get a uniform hot air temperature inside the dryer.  

Features

• Large quantities of products can be dried
• Fuel saving potential of about 25 - 30% (as compared to open smoking of produce)
• Uniform temperature profile resulting in simultaneous drying of produce
• Ducting can be laid in any room of the desired dimensions
• Smoke does not come in contact with the produce thereby ensuring good quality of dried produce
• Quality of produce better than that obtained by other conventional drying techniques
