PET Crystallizing Dryer

PET Crystallizing Dryer

NAMING PRINCIPLE

OCR-xxx

① ②

① Orste PET Crystallizer

② Hopper Capacity (L)

FEATURES

1. Simplify and improve drying efficiency.

2. Fixed speed of agitator makes materials not lump together during the crystallization.

3. Materials can be dried under high temperature to improve drying efficiency.

4. Cyclone dust collector is standard equipped, which is applied to dust-rich place. Can effectively reduce the load on filter bag, and reduce the numbers of filter bag cleaning, thus extend the life span of the filter bag.

5. With double overheat protector, 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. Given an alarm when the negative pressure is higher than the setting value, clean the filter to avoid blockage.

APPLICATION

OCR 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.

FUNCTIONAL SCHEME

Once material filling starts, heat blower starts up and material heating begins. Control cabinet would stop sending signals to auto loader when material filling amount is higher than material level switch. Then material heating lasts for a while. When temperature sensing needle detects the value of reaching the set crystallized temperature, material would be conveyed out via feeding device; meanwhile, as material level in hopper lowers gradually, filling device starts to supply the uncrystallized material accordingly to realize the continuous crystallization process.

When temperature sensing needle detects the temperature value of stopping material conveying, feeding device halts. If temperature rises again to reach the set crystallized temperature, feeding device will be activated to work so that the continuous crystallization process can be realized through this kind of circle.
