Product Introduction: The three-in-one moisture and drying machine is designed for engineering plastics with high hygroscopicity in the plastic industry, operating in a closed-loop state without contacting moisture from the external air. Additionally, the molecular sieve and closed regeneration technology lower the dew point temperature of the dried air inside the pipes to -45℃ (the dew point is the temperature at which water vapor in the air condenses into dew). It integrates drying, dehumidification, and conveyance, featuring simple feeding, compact structure, and robustness. Low dew point air not only evaporates and removes moisture on the surface of the plastic but also eliminates crystalline water within the plastic molecules, thereby reducing the moisture content within the plastic material. Suitable for granular materials such as polycarbonate, polyester, TPU, nylon, polymethyl methacrylate, polytetrafluoroethylene, polyethylene, etc. With the widespread application of engineering plastics, the moisture and drying machine is gradually replacing traditional hot air dryers. Features of the three-in-one moisture and drying machine: 1. Stable dew point, suitable for drying at -40℃ to -50℃. 2. Double-layer stainless steel drum insulation saves electricity and is easy to clean. 3. Closed-loop control reduces heat and dust emissions, saving electricity and promoting environmental protection and cleanliness. 4. Uses non-contact solid-state relays for heating control. 5. No need for cooling water or cooler. 6. The compression system saves 30% more electricity than other honeycomb and double-tube systems.
