  • Evaporators - an overview | ScienceDirect Topics

    R. Paul Singh, Dennis R. Heldman, in Introduction to Food Engineering (Fifth Edition), 2014. Evaporators are commonly used to concentrate foods by using heat to evaporate water from the food. As the liquid is concentrated, its boiling point is elevated. Using low pressure, boiling of liquid foods (such as juices) is carried out at low temperatures and the heat labile food attributes are preserved.
