Thermal performance evaluation of modified active greenhouse dryer

A prototype model of modified active greenhouse dryer has been designed, developed, and tested in no-load conditions at the Maulana Azad National Institute of Technology, Bhopal, India. The proposed dryer has been tested under two conditions: (1) with covered inside floor and (2) with uncovered floor. This study revealed that the covered floor condition of the greenhouse is favorable for drying due to higher raise in greenhouse temperature and decrease in its relative humidity.
