Heat Exchangers by Dairy Machinery
Main Features:
1.Plate heat exchanger can realize full countercurrent form; the temperature correction coefficient is 1.
2.The corrugation of the sheet in plate heat exchange can make fluid generate turbulent flow with minor Reynolds number; its heat transfer coefficient is 3-5 times as large as that of shell-and-tube heat exchanger, reaching 7,000W/m2K at the most.
3.Plate heat exchanger features compact structure. The heat-exchanging area per unit volume is 2-5 times as large as that of shell-and-tube heat exchanger; the floor area occupied by plate heat exchanger is approximately one fifth to one tenth of the area occupied by shell-and-tube heat exchanger, given that the same heat exchange task is fulfilled by them.
4.The sheet in plate heat exchanger is only 0.5-0.8mm in thickness. The heat-exchanging area needed by it is smaller than that needed by shell-and-tube heat exchanger, given that the same heat-exchange task is fulfilled by them. The weight of plate heat exchanger is only around one fifth of the weight of shell-and-tube heat exchanger.
5.As for water-water heat exchange, the lowest temperature difference at the end can be lower than 1ºC, which is extremely beneficial to the recovery of low-temperature heat energy.
6.The dirt coefficient of plate heat exchange is small for the following reasons: Violent turbulent flow of fluid causes low-possibility deposition of impurities; the dead zone of inter-sheet channel is small; the heat-exchanging surface made of stainless steel is smooth, which results in less corrosive attaching.
7.Plate heat exchange allows for heat exchange with three or more media via the middle clapboard, which is extensively applied in milk product processing techniques.
8.To clean the sheet mechanically, unscrew the clamping bolt in plate heat exchanger to loosen the binding of plate and then unload the sheet, featuring extremely convenient maintenance.
APPLICATIONS
Pasteurization, Heating, Cooling and Heat Recovery in liquid/liquid and steam/liquid.
Plate heat exchanger consists of heat transfer plates, frame, tightening devices and connecting nozzles.
The plates are made of compression molded sheet metal with corrugations designed to achieve maximum heat transfer. Each plate is provided with a synthetic rubber gasket which seals the fluid in. The plate is hung on the upper guide bar and is tightened between the stand (fixed frame) and the end plate (movable frame). The fluid flows through a narrow space between the plates and heat is exchanged across the plate surfaces. In the plate heat exchanger, the fluids can travel in various directions of flow, such as looped, in series of plates.
