Honeycomb Pre-Crystallization Dehumidifying & Drying Machine

PET resin raw materials are high polymerized products, widely used in packaging materials for textiles, pharmaceuticals, film tapes, industrial threads and tableware.PET has high water ratio. When it is melted under high temperature, PET willAppear air bubbles, crack and yellowing drawbacks.The water ratio of the pretreated materials is from 0.4 to 0.5%. It is necessaryTo decrease the water ratio to 0.01% and under 100PP (1PP=1/million), even to 50PP to produce high quality resin.Pre-crystallization dehumidifying & drying unit machine.
