In order to concentrate 3200 kg/h of a liquid food containing 5wt% solid to 10 wt% solid, a single effect evaporator is beingused, with a heat transfer area of 44 m². The feedenters at 20°C. Saturated steam at 120°C is used for heating andthe pressure in the vapor space of the evaporator is 47.4 kPa Theoverall heat transfer coefficient in the evaporator is 1187W/m².°C. There is boiling point rise in the evaporator.The specific heat of liquid food is a function of solid content anddefined as (Cp= 5.0 – x) kJ/kg.K, where x is the mass fraction ofsolid in the solution. The specific heat of liquid water and watervapor is 4.1 kJ/kg.K and 1.8 kJ/kg.K, respectively. Calculate thekg/h of steam used in the process.
