Abstract
Falling film evaporators is an essential equipment of dairy powder production facilities. Evaporation is one type of thermal separation processes which makes the evaporation plant fundamentally energy intensive. Hence, improvements to its operation can have a significant impact on the energy usage. The studied plant has a two-effect falling film evaporator. Based on the current setup of the studied evaporator, a helical heat exchanger is designed and installed in order to reduce the steam usage by recycling the heat from vapor. With the new heat exchanger, one extra heat exchange step is added for transferring heat from hot vapor to cold liquid product. The results demonstrate that the total usage of steam, cooling water and electricity have been reduced.
