Centrifugal Dehydrator

This device consists of six parts: exhaust air, agglomerate catcher, circulating water tank, heat exchanger, drying chamber, and pellet diverter valve.

The materials mixed by the twin-screw extruder will be cut into pellets by the pelletizer, washed away by the water flow in the cooling water pipe, and enter the centrifugal dehydrator from the top of the agglomerate catcher. The agglomerate will be separated by the catcher and slide out from the bottom channel. The pellets and water will enter the drying chamber together. After dehydration by centrifugal force, the particles will exit through the distributor valve, and the water will enter the dirty side of the circulating water tank. As the water in contact with the materials may contain a small amount of material fines, the water on the dirty side will pass through the fines removal screen, and after sieving, it will enter the clean side. Then the water in the clean side, after being cooled by the heat exchanger, will re-enter the cooling water pipe for the next cycle.

The use of this equipment can significantly reduce the moisture content of the finished pellets, lowering the drying cost and time. Besides, it can also remove non-granular finished products and divert pellets of different diameters.

The centrifugal dehydrator is usually used in conjunction with underwater pelletizing lines and connected to the pelletizer through cooling water pipes for dehydration and removal of agglomerate.
