In order to make the greenhouse dryer more effective, various researchers have worked to minimize its various losses. Gupta et al. have proposed that for the small-scale greenhouse, loss of solar fraction through the north wall of the greenhouse is the most prominent loss [7]. It has attracted the attention of the researcher. There are various concepts proposed by various scientists and researchers. Jain has proposed the application of packed bed thermal storage in the north wall of the active greenhouse dryer [8]. A test was conducted to dry onion in the proposed dryer. Onion took only twentyfour hours to dry up in the proposed dryer.
