A solar dryer was designed and constructed to dry fodder for livestock. The objectives of this project were to design and construct solar dryer systems for fodder drying and to evaluate the performance of the systems developed so that farmers can compare and choose an appropriate drying system to dry fodder. Two types of solar driers were designed in this study named as a) prototype solar dryer and b) greenhouse solar dryer. The performances of both systems were evaluated by observing their ability to achieve and maintain an optimum temperature of 60oC for a perfect drying process. In 2011, the prototype solar dryer was constructed at the Malaysia Veterinary Institute; however the results obtained were not as expected as the highest temperature achieved with the system was 44.9oC. Therefore, in 2012, the greenhouse solar dryer was constructed to replace the prototype model and the system has the ability to achieve the temperature up to 72.7oC.
