Question Statement:
Osmotically dehydrated cherries, finish-dried from 18% (dry basis) to 11.5% (wet basis) moisture content, final mass flow rate 5000 kg/h. Dryer efficiency 70%, latent heat 2345 kJ/kg, c_p(air)=1.005 kJ/kg·K, drying temperature 50°C, specific volume of ambient air at 25°C = 0.866 m³/kg. The air flow requirement, in m³/min, is: [note: marked "Marks to All" in the official key owing to an ambiguity/error in the original question]
