A peach puree (100 kg) initially has a concentration of 7.2% total solids and is heated to 23 to 84 C using steam. Calculate the concentration of total solids in the hot mash leaving the operation. The process is carried out at atmospheric pressure, that is, at a steam temperature of 100 C. The specific heat of solids is 2.10 kJ/(kg K) and for water it is 4.186 kJ/(kg K)..
