A tomato-juice evaporator takes in juice at the rate of 1200 kg/h. If the concentrated juice contains 35% of solids and the hourly rate of removal of water is 960 kg, (a) calculate the moisture content of the original juice, (b) the quantity of steam needed per hour for heating if the evaporator works at a pressure of 25 kPa. Assume no heat losses. Assume saturated steam at 50% quality is used to heat the evaporator at a temperature of 125 oC. Condensate exits at 125 oC.

    3-9. 10,000 kg / h of a 20% NaOH solution are treated in a simple evaporator and must be concentrated to 50% by weight. The steam used as the heating medium is saturated steam at 4 at overpressure. An absolute pressure of 150 mm Hg is maintained in the evaporation chamber. The integral coefficient of heat transmission is 2,500 Kcal / m2.h.C. If the supply enters the evaporator at 20 ° C, calculate: a) The heating surface. b) The hourly...

    Tomato juice having a concentration of 12 wt% solids is being concentrated to 25% solids in a film-type evaporator. The maximum allowable temperature for the tomatojuice is 135 °F, which will be the temperature of the product. The feed enters at 100 °F. Saturated steam at 25 psia is used for heating. The overall heat-transfercoefficient U is 600 btu/h·ft2·°F and the area A is 50 ft2. The heat capacity of the feed cP is estimated as 0.95 btu/lbm·°F. Neglect any...
