Experimental results from the transient drying of sheets of polyester in an infrared (IR) dryer were used to derive a performance model. Separate drying experiments were done using sheets of material of various densities and thicknesses. The formulations expressed the core temperature of the web to the surface temperature of the web as a function of the residency time in the dryer and the elect...

The present study examined the effect of ultrasonic pretreatment at three time levels 10, 20 and 30 min on some thermodynamic (effective moisture diffusivity coefficient(Deff), drying time, specific energy consumption (SEC), efficiency, thermal efficiency) physical (color shrinkage) properties kiwifruit under hybrid hot air-infrared(HAI) dryer different temperatures (50, 60 70 °C) thicknesses (...
