Products Description
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.

A PET crystallizing dryer is a specialized industrial dryer designed to enhance the crystallinity of PET (polyethylene terephthalate) resins. It uses controlled heat and agitation to raise the crystallinity of PET flakes or granules, improving their melt flow and reducing moisture content for downstream processing. The unit is commonly used in plastic recycling lines and PET bottle-to-fiber production.
This machine typically features a conical or cylindrical hopper with an internal agitator running at a fixed speed to prevent material clumping. High-temperature drying air is circulated through the material bed, and a cyclone dust collector is integrated to capture fines and reduce filter maintenance. Double overheat protection safeguards against thermal degradation.
Choose a PET crystallizing dryer when upgrading recycled PET for injection molding, fiber spinning, or sheet extrusion. It is less suitable for heat-sensitive polymers or non-crystallizable materials.

Best Fit & Nearest Alternatives
Best suited for:
- PET flake or pellet pre-treatment before extrusion or molding
- Recycling facilities upgrading post-consumer PET for higher-value applications
- Operations requiring reduced moisture and increased crystallinity for improved processing stability
Not ideal for:
- Processing non-crystalline polymers (e.g., PP, PE)
- Applications where ambient drying or dehumidifying is sufficient
- Scenarios requiring ultra-low temperature profiles
Compared to a hot-air dryer, this crystallizing unit adds crystallinity, improving downstream performance; versus a crystallizer alone, it combines drying and crystallization in one step.
What Drives the Price
- Hopper capacity and material throughput
- Presence of cyclone separator and filter system
- Temperature control precision and safety features
Unit pricing scales with MOQ and volume tiers. Request a quote based on hourly or daily output requirements; pricing varies by configuration and automation level.
Lead Time, Shipping & Returns
- Lead time: Typical lead time ranges from 45 to 90 days after PO and deposit. Confirm with supplier for current backlogs.
- Shipping: Standard modes include sea freight (FCL/LCL) for bulk orders and air freight for urgent smaller shipments. Door-to-door and DDP options may be available.
- Returns & defects: Returns are accepted only for confirmed manufacturing defects within the warranty period. Inspection must be completed at destination within 7 - 14 days. Buyers typically arrange inspection and coordinate return logistics with the supplier.
Handling & Application Notes
- Avoid overfilling; maintain a clearance of at least 10% in the hopper to ensure proper airflow and agitation.
- Preheat the unit gradually to target temperature to prevent thermal shock to PET material.
- Clean the cyclone and filter bags regularly to maintain airflow and prevent pressure buildup.

Frequently Asked Questions (FAQs) on PET Crystallizing Dryer
1. What is the maximum operating temperature of the PET crystallizing dryer?
The unit can operate up to approximately 180°C, suitable for PET crystallization without thermal degradation when properly controlled.
2. Is the cyclone dust collector mandatory for this model?
Yes, the cyclone dust collector is standard equipment to handle fines generated during PET crystallization and reduce filter maintenance frequency.
3. Can this dryer process other polymers besides PET?
This unit is optimized for PET due to its crystallization temperature profile. Processing other polymers may require adjustments and is not recommended without supplier confirmation.
4. Is stainless steel construction available?
Yes, stainless steel hopper and wetted parts are available as an option for corrosion resistance and hygiene.
5. What kind of agitator is used in this dryer?
The dryer uses a fixed-speed agitator - typically a paddle or ribbon type - to prevent material lumping during high-temperature drying and crystallization.
6. Does the supplier provide installation and training?
Yes, the supplier offers on-site installation, commissioning, and operator training as part of the delivery package.
7. What maintenance is required for the cyclone and filter system?
Regular emptying of the cyclone bin and periodic cleaning of filter bags are required to maintain airflow and prevent clogging.
8. Can the dryer be integrated with a pelletizer line?
Yes, this crystallizing dryer is designed to feed directly into pelletizing or extrusion systems, improving material consistency and throughput.
