7. Strawberries contain 15% solids and 85% water. To produce 100 kg/h of strawberry jam, crushed strawberries and sugar are mixed in a mixer. After mixing, the mixture is sent to a heated evaporator where water is removed. The strawberry jam leaving the evaporator has a final composition of 63% sugar, 7.7% solids and 29.3% water. All percentages given are in mass percent. (a) Draw a block flow diagram of the process. (b) Calculate the mass of crushed strawberries and sugar fed to the mixer. (c) Calculate the mass flow rate of water removed in the evaporator. (d) Calculate the composition of the mixture leaving the mixer.
