Product Description
In modern plastic recycling systems, moisture control is one of the most critical factors affecting pellet quality, extrusion stability, and downstream production efficiency. The Vertical Centrifugal Dryer is specially designed to remove water, detergent residue, and contaminants from rigid plastic flakes and granules after washing processes.
Widely used in PET bottle recycling lines, HDPE bottle washing plants, and rigid plastic recycling systems, this machine uses high-speed centrifugal force to reduce material moisture content to below 5%, preparing plastics for pelletizing and extrusion applications.
At Zhangjiagang Chenxing Machinery, we manufacture durable and energy-efficient vertical centrifugal dryers tailored for global plastic recycling plants seeking stable output, low energy consumption, and high automation performance.
A Vertical Centrifugal Dryer, also known as a vertical spin dryer, is a high-speed dewatering machine used to separate water from plastic flakes or granules through centrifugal force.
The machine is commonly installed after:
Sink-float separation tanks
Friction washers
Hot washing systems
Plastic rinsing tanks
Its primary function is to rapidly remove surface moisture and cleaning chemicals before the material enters the thermal drying or pelletizing stage.
This equipment is especially suitable for:
HDPE rigid flakes
PP rigid plastics
Crushed engineering plastics
Regrind materials
For flexible plastic films and woven bags, a horizontal centrifugal dryer is generally recommended instead.
Many recycling factories underestimate how moisture directly impacts final product quality.
Excess moisture can cause:
Unstable pelletizing
Air bubbles during extrusion
Reduced pellet density
Poor melt filtration performance
Increased energy consumption
Lower recycled plastic value
A high-performance vertical centrifugal dryer helps recycling plants:
Improve pellet quality
Increase production stability
Reduce drying costs
Improve extrusion efficiency
Minimize downstream defects
For PET recycling lines especially, maintaining low moisture content before pelletizing is essential for achieving high-quality recycled PET flakes and pellets.
The vertical centrifugal dryer operates using high-speed centrifugal dewatering technology.
Wet PET flakes or rigid plastic materials enter the machine from the bottom inlet after washing.
Inside the machine, a high-speed rotor equipped with slanted paddles agitates and lifts the material upward.
As the rotor spins rapidly, centrifugal force pushes water outward through detachable perforated screens.
Separated water and contaminants are discharged through drainage outlets at the bottom of the machine.
The airflow system transports the dried plastic flakes upward and out of the machine for the next processing stage.
This vertical structure allows efficient dewatering while maintaining continuous production flow.
The machine can reduce moisture content to below 5%, significantly improving downstream pelletizing performance.
The reinforced rotor and wear-resistant paddles ensure stable long-term operation under continuous industrial workloads.
Suitable for fully automatic PET bottle washing and rigid plastic recycling lines.
Detachable screen structure allows convenient cleaning and maintenance.
Integrated airflow conveying system ensures smooth material discharge.
Optimized rotor structure minimizes energy consumption while maintaining strong drying capacity.
The vertical centrifugal dryer is widely used in:
Removing moisture from washed PET flakes before hot air drying or pelletizing.
Drying rigid HDPE flakes after sink-float separation and friction washing.
Reducing moisture before extrusion to improve pellet quality.
Suitable for rigid post-consumer and post-industrial plastic recycling operations.
As environmental regulations become stricter worldwide, recycling plants increasingly require:
Higher purity recycled plastics
Lower operational costs
More stable automation systems
Lower energy consumption
Better pellet consistency

A vertical centrifugal dryer removes water and detergent residue from rigid plastic flakes and granules after washing processes.
Suitable materials include:
PET flakes
HDPE flakes
PP rigid plastics
Crushed rigid plastics
Plastic granules
The output moisture content can generally reach below 5%, depending on material condition and washing process.
No. For flexible materials such as PE film and woven bags, a horizontal centrifugal dryer is more suitable.
It is usually installed after:
Sink-float tank
Friction washer
Hot washing tank
and before thermal drying or pelletizing.
Yes. Chenxing Machinery can customize capacity, motor power, screen design, and structure according to customer production requirements.
