Kinetics Modeling of Thin-Layer Drying of Button Mushroom in Combined Infrared-Hot Air Dryer

Drying of button mushroom in a combined infrared-hot air dryer at power of 150, 250 and 375 W, temperatures of 50, 60 and 70 °C and air flow rates of 1, 2 and 3 m/s was investigated. The effect of lamp power, temperature and air flow rate on time and drying rate, moisture diffusion coefficients and activation energy were evaluated in a completely randomized design. The results showed that the effect of lamp power, temperature and velocity of air displacement on the drying process of button mushroom production is significant (p
