In present analysis it has done some modifications in existing solar greenhouse dryer here it incline the roof of dryer according to the latitude of Bhopal city and also we use black plastic film to increase the absorbing capacity of the dryer with the use of fans for forced convection purpose. To check the effect of inclination with black plastic film, simple greenhouse dryer has been made and it compare results in two different conditions. The performance of modified, simple and open sun drying compared in terms of drying rate in two conditions and also with visual appearance of dried potato flakes. To minimize the obstacles, the roof of dryer is inclined and black plastic film was used with forced convection method by which the heat absorbing capacity is increased. It is found that the dryer with black plastic give better result than the dryer with all side transparent plastic. The modified green-house gives best result in all the condition of atmosphere. It gave better condition for drying potato flakes such as high temperature and less humidity than simple greenhouse dryer and atmosphere.
