Centrifugal Dryer For Plastic Underwater Pelletizing
Often referred to as Plastic UWP Centrifugal Dryer Machine
An underwater pelletizing centrifugal dryer is a key component in polymer pelletizing lines. After pellets are cut in water, the dryer uses centrifugal force and airflow to separate and remove moisture quickly. This ensures low residual moisture, high pellet quality, and efficient water recirculation for continuous production.

The NICETY Centrifugal Dryer delivers efficient moisture removal. With its high-speed rotor and reverse airflow, it ensures pellets are dried quickly and uniformly. A versatile solution for modern pelletizing lines.
Centrifugal Dryer For Under Water Pelletizing
Main applications:
- All Virgin Polymers
- Compounds
- Masterbatches
- Recycling Applications
- Micro-Granular Compounds
- Recycling of recycled materials
- Thermoplastic Elastomers
Pre-dewatering:
Gravitational separation through a slotted screen
Primary drying:
Separation by rotor blade and screen impact, aided by reverse airflow; residual pellet heat evaporates surface moisture.
Pellet conveyance:
Pellets are lifted and hurled by a spinning rotor with inclined lifting blades
How Centrifugal Dryer Works
Slurry Entry
Pellet-water slurry from the pelletizer enters the dryer either horizontally or vertically.Primary Water Removal (1)
Gravity separates up to 95% of the process water.Pellet Transport & Separation (2–3)
The spinning rotor with inclined blades drives pellets upward in a spiral.
Adhering water is expelled through the cylindrical screen.Reverse Airflow & Negative Pressure (4–5)
Reverse airflow generates negative pressure at the pellet outlet.
This allows pellets to exit while retaining moisture inside the dryer.Water Recirculation (6)
Collected water is returned to the process loop.Result
The combination of centrifugal force, reverse airflow, and pellet temperature control ensures high-quality pellets with minimal residual moisture.

The dryer separates water from polymer pellets after cutting, using centrifugal force and airflow, ensuring pellets are dried efficiently with low residual moisture.
It is suitable for a wide range of thermoplastics, including PE, PP, PET, ABS, PA, TPE, and various masterbatches or recycled materials.
Residual moisture can be as low as 0.05–0.2%, depending on polymer type, pellet size, and process parameters.
Up to 95% of water is removed by gravity before entering the rotor, and separated water is collected and recirculated back into the process loop.
It offers high efficiency, compact footprint, continuous operation, low energy consumption, and excellent pellet quality.
Routine inspection and cleaning of the rotor, screen, and seals are recommended. Bearings and wear parts should be replaced periodically to ensure stable performance.
