plate heat exchanger
Quick Summary
A plate heat exchanger is a type of heat exchanger that uses a large number of thin, vertical steel plates clamped together in a frame. These plates are separated by gaskets that create channels for liquids to flow between them. The liquid product and a heating or cooling medium, such as hot water, are pumped through alternate channels. The gaskets prevent the product and the medium from mixing, ensuring efficient heat transfer.
Plate heat exchangers are particularly effective for rapid heating and cooling applications and are commonly used in processes like pasteurization for liquids such as milk and fruit juices. This design allows for a large surface area for heat exchange within a compact unit.1
