Pet Crystallizers

SCR closed-loop crystallizers are used for constant crystallization of un-crystallized PET regrinds or pellets. Processed materials can then be dried and dehumidified directly. This system mainly consists of heating elements, insulated hopper and agitator screw mixing device. After un-crystallized PET materials fed into the hopper, the system starts crystallization and agitator starts blending to prevent formation in lumps. Crystallized materials can be conveyed to material storage bin or into drying hopper.

Features
Standard configuration
1) Fixed speed of agitator makes materials not lump together during the crystallization.
2) Simplify and improve drying efficiency.
3) Materials can be dried under high temperature to improve drying efficiency.
4) Cyclone dust collector is standard, which is applied to dust-rich place. Can effectively reduce the load on return-air filter, and reduce the number of times of filter cleaning,thus extend the life span of the filter.
5) With double overheat protectors, it can reduce the possibility of either mechanical or man-made problems.
6) Equipped with rotary valve with good sealing performance, which can output crystallized material accurately.
7) Equipped with material level switch, which can detect material level accurately and make operation reliable.
8) Equipped with negative pressure tester to immediately test the ventilation of the filter. Give an alarm when the negative pressure is higher than the setting value, clean the filter.
