Chem Plate Type Evaporator involves the use of a number of plate packs, each consisting of alternate plate cavity for steam and the product. Multiple plates are hung in a frame which resembles that of a plate heat exchanger. Each body of Plate Evaporator are designed to give full flexibility in thermal performance. Normally, the feed liquor is introduced at a temperature slightly higher than the evaporation temperature in the plate annuli and the ensuing flash distributes the liquor across the width of the plate. Useful to handle asymmetrical flows - when a limited pressure drop is acceptable for one of the media but pressure drop is not a limiting factor for the other. Also used for even and gentle evaporation of the product.
