SOLAR TUNNEL DRYER(CAE, Raichur maodel)

The solar tunnel dryer is a polyhouse dryer suitable for drying of most of the food crops. It consists of a tunnel type semi-cylinderical drying chamber provided with windows to allow the ambient air to enter the dryer. An exhaust fan is provided to evacuate the moist air from the dryer. A sliding door is also provided to facilitate easy handling of the produce. Trolleys and trays (50 Nos.) are provided to hold one tonne chilli for drying. The maximum temperature of the air inside the dryer was observed to be 53-54°C. The drying time of 43-45 hours is required to dry one tonne byadagi chilli against 70 hours required for open sun drying. Saving in drying time was observed to be about 40 -60 per cent by using this dryer for drying Byadagi chilli. The dryer can also be used for drying grapes, sapota, figs, mango, amla, fish etc.
