Product Profile of Agricultural Solar Crop Dryer
Agricultural Solar Crop Dryer consists of semi-cylindrical tunnel structure which is covered with ultra violet stabilized polyethylene as collector material and the solar radiation is transmitted through ultra violet collector sheet to tunnel chamber. The Solar Crop Dryer is walk-in type and facilitates loading and unloading of the product to be dried. The Solar Crop Dryer has the floor constructed with cement concrete and coated with special black or high thick black polyethylene sheet. Process Ekuipment Engineers is manufacturing Agricultural Solar Crop Dryer.
Key Features of Agricultural Solar Crop Dryer
- Solar crop dryer is working based on Green House Effect principle.
- The solar radiation is transmitted through ultra violet collector sheet to tunnel chamber.
- The polyethylene cover has the property of transfer short-wave radiation and opaque for long wave radiation.
- After reaching absorber surface, the shortwave radiation is converted into long-wave thermal radiation and reflected back to collector material.
- As ultra violet polyethylene collector is opaque for long-wave radiation hence heat trapped inside the dryer, raising its temperature.
- It is expected that 15-20°C increase in temperature above ambient temperature inside the solar crop dryer to dry the product from initial moisture to safe storage moisture.
