Solar dryers as a promising drying technology: Review

C. K. Pardhi

Abstract


Dryers are used in the food industry and agriculture to extend the life of soldiers. Heat energy is needed to remove water in the drying process, which can be produced from various sources. Solar thermal energy is one of the most suitable sources for drying processes and has several advantages, such as the avoidance of greenhouse gases and its availability. Due to the influence of various factors on the performance of solar dryers, this article focuses on the work done on these systems. In this regard, various types of solar dryers are discussed, including a direct, indirect, mixed mode, and solar hybrids. Based on the results of this review, it can be concluded that the performance of solar dryers depends on several parameters, such as dryer, solar radiation, drying time, and operating conditions. Also, it was discovered that several methods may be used to enhance the general performance of solar dryers, including the use of thermal energy storage systems, a solar tracker, and changed materials. Also, there is a lot of room for efficiency and dependability improvements through the integration of solar dryers with other systems. Solar dryers have been researched in greater detail utilizing exergy analysis in addition to energy analysis and drying capacity, and the relationship between exergy efficiency and operating parameters is looked at. The purpose of this paper is to present an overview of the hybrid solar dryer and its variant for further research
