An algorithm of a convectional factory tray dryer with performance evaluation on the functionality of the dryer was reported. This is required to reduce drying time of material as well as man-machine interface which can cause slow operation and contamination of the material been dried. The algorithm of the model was developed with an interface accorded with computer software (MATLAB) for its quick implementation. This algorithm was able to predict parameter values needed for dryer automation such as heating element diameter, heating chamber length, pumping power and flow rate of air. Result generated from the algorithm, was found to be of importance in fabrication of a convectional factory electric tray dryer. The algorithm was also validated by manually calculated parameter values. The results were found to be the same, this proved the effectiveness of the algorithm
