Solar Drying System for Jute Fibre

Jute is one of the most important crops in Bangladesh and its quality, to a great extent, depends on the system used for drying the fibre. In this study, a solar drying system for jute fibre is developed in order to improve the quality of raw-jute and jute products. A thorough review of existing literature is presented in order to exhibit the current state-of-art of fibre drying. The solar energy availability is reviewed also in the context of Bangladesh. The theoretical and experimental investigations of different solar air collectors used as solar air heaters are carried out. The thermo-physical properties of jute fibre are defined and air heater ducts, drying chamber and fan and ducting systems are designed which cover the technical aspects of the study. A cost benefit analysis of the developed system is carried out to examine its economic feasibility from where it is found to be a feasible proposition.Necessary discussion and conclusions are laid down. Finally recommendationsare put forward for future and further work.
