Drying process by central drying room
The central drying room is constructed with a dimension of 3.30 m×4.80 m×3.20 m at capacity of about 3 Ton (3,000 kg) of agricultural products. It generates room temperatures to be over 80°C. The hot water t ransfers heat into the heating coil in the drying room. The air inside the room is heated by the 20 kW heating coil. Efficiency test of the empty drying room showed that the room temperature increases from 25°C to be over 80°C within 5 minutes. The heating efficiency of drying room is around 80% (η ) with the water temperatures entering and leaving
heating coil
