Abstract

In the work being presented, the expressions for crop and moist air temperatures of open sun drying system in quasi - static state conditions have been derived. The analysis was carried out by writing energy balance equations for crop surface and moist air above the crop surface. A computer model was developed to predict the crop temperature and moisture evaporation rate of potato slices of approximately 2.5 mm thickness exposed to open sun radiation environment. The validation of theoretical thermal model was carried out by experimental model for 18 April 2015 and 19 April 2015 in Lucknow, India. Internal heat and mass transfer coefficients have been evaluated and its average value 3.142711714 (w/m2  ) has been achieved. Predicted value of moisture evaporation rate and crop temperature has been computed and a fair agreement has been observed between predicted and experimental results.  Keywords: open sun drying, crop temperature, moisture evaporation, heat and mass transfer coefficient Cite this Article Srivastava A.K., Dr. Shukla S.K.
