Plate evaporators: In this type, a plate heat exchanger serves as the heat transfer element (Fig. The unique design of plate-type evaporator and plate-type condenser have higher thermal efficiency compared to traditional shell-and-tube facilities, it means the required heat exchange area is greatly reduced. 2 and 3 are elevational views of a plate element and a spacer frame, respectively, shown in FIG. It is one of the most popular feature of plate-type evaporator that you can just add or remove the plate group based on the current frame if you want to expand or reduce the capacity, and it is the major advantage compared to shell-and-tube evaporator which has the fixed capacity when installing. 6. Along the external heat transfer surface, however, the wetted perimeter is constant. The main applications of following heat sensitive product. SWEP evaporators facilitate stable and efficient operation down to very low refrigerant flow rates and low superheat, due to our patented distribution systems. Another suggestion is to use a larger number of plate interspaces for the downward flow than for the upward flow. Plate Evaporator is associated type of Semi-Welded Plate Heat Exchanger, rising film plate evaporators and are suitable when concentration and viscosity of fluid are high. Short material holding time. 3) For multi evaporator system. You can see the the example above, there are two holes separated by a metal plate. The very low retention means that at any given time, there is almost no product left in the evaporator of the plate-type evaporator. The evaporation passages E encompassed by two adjacent heat transfer surfaces are sealed from the surroundings by means of an annular gasket 22 in the spacer frames 2. For example, the plate pack can be surrounded by a cover for product steam, and the plates can be designed to allow free product discharge at the lower end of the plate pack. 1, the path of the product to be evaporated and the evaporated product with generated steam is shown in full lines with arrows indicating the flow direction; and the path of the heating medium is shown in broken lines with arrows indicating the flow direction. Not only covering less space, saving valuable space, but also reducing investment costs and maintenance without sacrificing reliability and … 859,876 discloses an evaporator in which the liquid to be evaporated is first forced upwards between one pair of plates and then downwards between another pair of plates. The invention also includes such plate evaporators in which a pair of heat exchange plates are joined together by any sealing arrangement, such as welding, around the periphery of the plates to form closed spaces for product or heating medium. Further, it is not necessary to feed or discharge all the flows through ports located inside the periphery of the plates. It is a big advantage to heat sensitive products if products stay when evaporating in a short time. 6. Of course, the inlet and outlet ports 8-9 for the heating medium as shown in FIG. Evaporated product and generated secondary steam flow in the lower part of the evaporator towards the outlet 7 through apertures 12 and 12' in the plates 1 and 1' and corresponding passages 14 sealed by gaskets 13 in the spacer frames 3. As the original plate type evaporator, the Rising/Falling Film Plate system is a flexible, multi-duty unit engineered to handle small to medium production runs of heat sensitive products. 4. Save space and Save installation budget. The reason for this is that although the passage's cross-sectional area increases in the flow direction due to the downwardly diverging plates 1 and 11 (FIG.
