Effect of airflow on Heat Pump in drying mode

Manufacturers develop new technologies to process sensitive food materials to supply new products with improved properties and high quality. Heat pump technologies for drying can contribute to increased productivity, product quality, environmental and energy-saving benefits. Development of heat pump increase to decrease the drying time. A heat pump has been designed and fabricated. This paper improves the drying process with a variance air flow of the heat pump. During the experiment, the temperature, and relative humidity of hot drying air was the measure. The heat was analysed during the drying experiment. The result showed that the airflow of the drying has a high impact on drying. The temperature on the drying are plotted. This fact suggests that the direct contact on surface commodity, made the temperature on commodity has high.
