Generally, solar dryer cabinets are made up of sheet metals that are heavy, costly, tend to rust over time, and possess the high heat rate to the outer atmosphere. In order to overcome these drawbacks, this research urges to develop a natural fber reinforced polymer•based cabinet dryer, specially designed and fabricated for the purpose of solar drying. Nylon is used as the matrix material and Prosopis julifora in particulate form is used as the natural fber reinforcement. Te dryer cabinet was designed at industrial scale to dry 5kg of ginger at a single setting. Tis work also studies the efciency of the polymer composite cabinet integrated with a fat plate solar collector system that is coated with copper and black chrome attached to corrugated fns in between the absorber plate and storage medium. Te FRP chamber was compartmented in its interior with aluminium perforated sheets and experimentation was performed to determine the efciency of the composite cabinet based on reduction of heat loss from the system. Te performance of the coating, storage medium materials, and overall storage efciency were also studied. Te FRP cabinet resulted in a moisture level less than 8.5% within 4–7 days. Exergy studies showed 75% efciency and energy studies gave 25.5kJ/kg peak readings of drying efciency for a period ranging between 11 and 12hours. Tis was a 75% increment in energy efciency. Termal degradation of the FRP material was found to be stable up to 300 ° C. Te overall weight of the constructed polymer cabinet was 25% lesser than the conventional systems. 1.Introduction Ginger is a popular spice and cash crop all over the world. India, China, Japan, Nigeria, and Indonesia are among the countries that grow it. India is the world’s greatest producer and consumer of ginger, accounting for 32.75 percent of global output [1]. Te consumption pattern shows that green ginger is used 50% of the time, dry ginger is used 30% ofthetime,andseedmaterialsareusedjust20%ofthetime. Dried ginger has a large market and is exported due to its medicinal characteristics, which are used to cure stomach aches, nausea, indigestion, asthma, and other ailments [2]. To avoid waste due to microbial and fungal attacks, the economically valuable spice must be dried efectively to achieve a very low moisture content. Drying has tradi• tionally been crucial for preserving agricultural products and extending the shelf life of food [3]. Drying diferent food products can be carried out in a variety of ways. Te traditional open•air drying method has a number of drawbacks. For limiting product deterioration and re• ducing drying time, numerous energy•based dryers are available. Due to the increasing cost of energy, traditional dryers and drying procedures are not cost efective [4, 5]. Drying has become an energy•intensive and unafordable practice for farmers due to diminishing fossil fuel supplies and rising costs [6].
