They decide that it would be best to sell it as a frozen product and want you to calculate how much heat will have to be removed to reduce the temperature from 72°C at which it is processed to a final temperature of -18°C. Unfortunately, all they know about their product is that it freezes at -0.9°C. How much heat must be removed from a batch of their product to reach the desired

frozen temperature? For purposes of this calculation, express your answer to the nearest kiloJoule.

Formulation:

High molecular weight starches (dry)= 37.7 kg

Sucrose (5% moisture by weight)= 24.3 kg

Protein powder (dry)= 5.7 kg

Pure mountain spring water= 215.3 kg

Cp= 1.424 m_carb+ 1.549 m_protein+ 1.675 m_fat+ 0.837 m_ash+ 4.187 m_water+ 2.050 m_ice

Heat=mass*Cp*delta T

heat= latent fusion*mass

Latent fusion of water= 333.5 KJ/kg

latent heat of a material=latent heat of water*water content
