In a drying process, the moisture content of 25 kg of food will be reduced from 88% to 8%. The air used for drying enters the dryer at 85 ° C and exits at 70 ° C. 200 kg of saturated steam is used at 120 ° C to heat the air. Food enters the dryer at 30 ° C and exits at 65 ° C. Calculate the drying efficiency for an adiabatic operating dryer as the ambient air temperature is 25 ° C. (specific heat of food = 2.98kj / kg ° C)
