The stale bread drying is one of the best economical ways to prevent wastage of bread and prevent cancer in animals. In this study, the effect of convective dryer on drying time, energy consumption and water activity of stale bread were investigated. For this purpose, the design expert software is used to design the tests and investigate the impact of the temperature and velocity of the inlet air in the convective dryer on drying time, energy consumption and water activity of samples. The results of these studies showed that the laboratory data are in good agreement with the predicted data.
