What is the Plate heat exchanger device?
When the Plate Heat Exchanger is used for juice heating, the Heat Exchanger should be as close as possible to the evaporation tank, shorten the pipeline of juice and juice steam, and reduce the temperature drop. The juice inlet valve in front of the heat exchanger is controlled as the juice inlet valve of the evaporation tank (that is, the valve control between the heat exchanger and the evaporation tank is not used), so as to avoid additional pressure and even water hammer phenomenon in the heat exchanger when the evaporation tank is closed. When the amount of juice is reduced, it should be turned off at the same time the steam (or hot water) valve, to avoid the temperature and pressure in the device is too high.
The connecting pipes of plate heat exchanger should be properly treated. To prevent the weight of the pipeline and thermal expansion and contraction of the pull or thrust on its connection flange, the heat exchanger connection pipeline should be installed with 90° elbow. Its inlet valve should be before the drainage valve, before starting the pipe water and dirt discharge, to prevent water strike and bring into the dirt when starting. The material pipe should be provided with bypass and valve, and the bottom pipe should be set at the lower part. And there should be a test water pressure joint, before opening the two sides of the channel test water pressure inspection.
Thermometer and pressure gauge should be installed at each connecting nozzle. When heating with steam, the condensing water temperature should be only slightly lower than the steam temperature (calculated by saturation), if the drop is too large, there is water in the expositor, which will significantly reduce its heat transfer performance. The heat exchanger should be equipped with good steam condensate water removal equipment.
The plates of plate heat exchanger are compressed as a whole by end covers and bolts on both sides. One side of the end cover is fixed on the frame and us.
