Abstract

Generally farmers dry their agricultural products and food stuffs in open sun. In open sun drying the products were sprayed under sun and moisture evaporates from it. This open sun drying is having so many drawbacks such as dust contamination, insect contagion, microbial attack, Decadence due to rain etc. To overcome these drawbacks the new technology emerged in market is Solar Air Dryer. It is a device used for product drying and controlling product quality and taste with proper applications of solar energy. Solar dryer is operated during off sunshine period by using Thermal Energy Storage (TES) technology. Energy storage medium collects solar energy during sunshine period and supply it for product drying during off sunshine period. Developing efficient and cost effective energy storage in solar air dryer is as important as developing new energy sources. There are three kinds of TES technology namely sensible heat storage (SHS), Latent heat storage (LHS) and thermo chemical heat storage (TCHS). Out of these three technologies, due to high energy density and constant working temperature LHS technology is efficiently used in solar air dryer for drying agricultural products and foodstuffs in the temperature range of 45°C -90°C [10]. LHS technology uses Phase Change Material (PCM) as TES medium in solar air dryer which stores the thermal energy during sunshine period and supply the stored energy for drying products during off sunshine period. This paper presents the review on phase change materials, their corresponding performance in respective applications, related methods of performance enhancement of PCM and their applications and various designs of solar air dryers used to enhance its performance. Although a lot of research work on performance enhancement of LHS system has been performed and many valuable results have been obtained, there are still many works need to be performed. It is proposed that the novel phase change material will synthesized by Fischer’s esterification Method. By Fischer’s esterification of glycerin (i.e. Glycerol) with Acetamide in toluene with sulfuric acid as catalyst new PCM will be obtained. The comparative results of performance of glycerin, Acetamide and new PCM obtained by Fischer’s esterification of glycerin (i.e. Glycerol) with Acetamide; can be presented in graph and table format.
