Abstract
This study aimed on the construction of a prototype electric palay dryer that would be able to work indoors without the sun as the heating medium.
Upon building this prototype, we were able to visualize its potentials on how it would be improved and what its uses are.
The researcher was able to produce as a household level dryer that would let families who have palay (unhusked rice) stacks of their own to dry palay on their homes.

The study aims to promote the utilization of improvised palay drying machine from a discarded materials such a motor and a spinner from an old washing machine assembled in an old body of a gas range. The machine can help farmers to ensure the good quality of harvested grains, reduce harvesting losses and dependence on weather conditions.
There are 3 treatments made to determine the significance of the methods used in dying harvested grains. In treatment I-sun-dry method, Treatment II-blow-dry-method and Treatment III-blow-dry-with charcoal method. The amount of grain was kept constant. Each treatment used 3kg of harvested grains. There are three trials for each treatment. The length of drying time will be recorded. For every trial the amount of weight loss were measured to determine if dried palay was able to attain the desired dryness.
The data gathered were analyzed using ANOVA or analysis or variance. Results showed that there is a significant effect in using improvised palay drying machine. Treatment III showed the shortest time in drying palay. It took 3 minutes to dry 3kg of grains or an average of 1 minute to dry a kilo of harvested grains. On the other hand, Sun drying and mechanical drying method using improvised drying machine has no significant difference in attaining the desired dryness of palay. An average weight of 14%is desirable. Therefore, it is concluded that
