FEATURES of PET Drying Machine

• Simplify and improve drying efficiency.
• Fixed speed of agitator makes materials not lump together during the crystallization.
• Materials can be dried under high temperature to improve drying efficiency.
• 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.
• With double overheat protector, it can reduce the possibility of either mechanical or man-made problems.
• Equipped with rotary valve with good sealing performance, which can output crystallized material accurately.
• Equipped with material level switch, which can detect material level accurately and make operation reliable.
• 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.

OPTIONS of PET Drying Machine

Dehumidifier, hopper receiver, auto-loader, magnetic base, suction box, screw feeder.

APPLICATION of PET Drying Machine

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 of PET Drying Machine

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.

PARAMETERS of PET Drying Machine

We reserve the right to change parameters without prior notice.

Notes:

(1) Above Max.processing capacity is based on pellet material of 0.85kg/L in bulk density and 3-5mm in diameter.

(2) Power: 3ф, 230/400/460/575VAC, 50/60Hz.

Machine Details of PET Drying Machine

There is a large inspection window at the front side of the OCR crystallizer with transparent glass window, the operator can check the material level in the hopper without opening the door. Three strong screws are placed in trangle to make the door is well sealed without air leakage. Safety sensor to stop the turing of the agitator in case the operator open the door to clean the hopper without previous turn-off of the machine.

Temperature gauge and temperature sensor is installed at the air inlet of the hopper, the operator can check the actual temperature in the controller display and at the thermometer, maximum temperature of the machine is 200 degrees centigrade. The heating part and electrical cabinet is located at the right side of the machine for convenient operating and maintenance.

How to clean the PET crystallizer when we want to change drying materials?

A compressed air gun is suggested to blow the dust in the inner wall of the drying hopper, a white clean cloth with white oil is always used to wipe the wall after blowing by air gun. We don't suggest to clean the machine by water, especially for the electric parts.

There is not dead angle in the drying hopper and other material contact surface, no need to worry about the material residual.

Application Case Illustration of PET Drying Machine

A customer in Thailand bought our 1st PET crystallizer in the year of 2017 for crystallizing un-crystallized PET granules before applied to make PET masterbatch. Four years later in 2021, the production engineer in this company contacted us to order another PET crystallizer for their 2nd factory. The PET materials are very sticky and easy to be blocked before crystalizing, our Crystalizer is equipped with high-torque motor and strong structure, the performance is highly praised by this customer. We are very glad that our machine is still in good condition after 5 years non-stop running and have made much profit for the customer. We persist in designing, manufacturing good quality machines with long service life for our customers.
