Drying using solar radiation,i.e. drying direct sunlight,is one of the oldest techniques used by mankind to preserve agriculture based food and non-food products. This form of energy is free,renewable and abundant in any part of the world specially in tropical countries. However, in order to maximize its advantages and optimize the efficiency of drying using solar radiation,appropriate technology need to be applied order to keep this technique a sustainable one. Such technology is known as solar drying and is becoming a popular option to replace mechanical thermal dryers owing to the high cost of fossil fuels which is growing in demand but dwindling in supply.
Various topics in sun and solar drying are discussed in many scientific reports, research manuscripts and books. This project will be fabricating and testing for drying agriculture produceby using flat plate collector and vortex circulating bed. The model can predict the change in absolute humidity of air across the bed, the temperature of air, the moisture content and the dryer thermal efficiency. By using vortex circulating bed, efficiency is increase and reduces the time for drying.
