The heart of a PHE is a pack of embossed plates with apertures. The plates are assembled in a 180° angle to each other, resulting in flow gaps on each side. Each plate is provided with a gasket, which securely seals the flow gaps from the atmosphere and separates the two media used in the heat exchange. The gasketed plate pack is mounted in a rack and is compressed with tightening bolts between the fixed plate and the movable plate. To guarantee maximum heat transfer, warm and cold media are normally fed through the PHE in one-pass or multi-pass counter flow. Connections are on the fixed plate, but can also be on the movable plate for multipass flow.Multipass Plate Heat Exchanger is widely used in food industry such as salt, dairy, soy sauce, vinegar sterilization, cooling, animal and vegetable oil heating, cooling, beer production, heating and cooling of beer, wort, sugar, gelatin concentration, sterilization, cooling, manufacturing sodium glutamate.
