Performance evaluation of hot liquid transmitting system in a solar dryer
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 2
Abstract
The aim of this study is to evaluate the Operation of System of hot liquid transmission in an automatic solar dryer. In this research the automatic solar dryer in order to use solar energy for drying agricultural crops, was designed and constructed. we evaluated the influence of time setting of pump timer in 3 levels (5, 10 and 15 Minutes) and the environment temperature in four levels of (24, 28, 32 and 36 Degree Celsius) on the function of the solar collector and the dryer chamber. The measured parameters included the temperature of the solar collector, the maximum and the minimum temperature of the drying chamber. From variance analysis of data showed that Influence of environment temperature was significant in 1% on temperature of the solar collector, maximum and the minimum temperature of the dryer chamber. Also it showed that Influence of setting of the pump timer was significant in 1% on maximum and the minimum temperature of the dryer chamber. But it was insignificant on the temperature of collector. The results of this study showed that by increasing the environmental temperature, rises temperature of collector and dryer chamber was obtained, also in order to make a moderate and uniform temperature, 10 minutes were calculated for the time setting of the pump’s ideal level.
