This two-stage HDPE flakes pelletizing system consists of two sets of single screw extruders and integrates the function of feeding, plasticization, and pelletizing into a single step. The final product generated by this pelletizing machine are high-grade pellets/granules (see additional images below) that can be directly put into plastic injection machines or other applications.

The Ultimate Guide to Thermal Drying Machines in Plastic Recycling
Welcome! If you’re in the plastic recycling industry, you know that quality is everything. After plastics like PET bottles or LDPE film go through a rigorous washing and dewatering process, one final, critical step remains: achieving an exceptionally low moisture level.
This is where a Thermal Drying Machine becomes your most valuable player. Let’s dive into how this essential piece of equipment works and why it’s a game-changer for producing high-quality, valuable recycled plastics.
Why is a Thermal Dryer So Essential? The Problem with Moisture
After mechanical dewatering, plastic flakes and film fragments still retain some residual moisture, typically between 5-15%. While this might not sound like much, this level of moisture can cause serious problems during the final pelletizing stage:
- Poor Quality Pellets: Trapped moisture turns to steam in the extruder, creating bubbles and voids in the final plastic pellets, making them weak and inconsistent.
- Production Issues: Moisture can cause processing instability, leading to production delays and lower output.
- Reduced Value: Inconsistent, low-quality pellets fetch a much lower price on the market.
A thermal drying machine is the definitive solution, engineered to bring moisture content down to the industry-standard of less than 3%, ensuring your final product is pure, dense, and ready for high-value applications.
How Does a Thermal Drying Machine Work?
Think of it as a highly sophisticated and powerful hairdryer designed specifically for plastics. The process is both simple and incredibly effective:
-
Material Inlet & Conveyance: Washed and dewatered plastic material is fed into the system and conveyed into a long network of stainless steel pipes.
-
Hot Air Injection & Tumbling: A powerful blower pushes high-velocity hot air through the pipes. As the plastic tumbles and travels, every piece is fully exposed to the hot air, causing moisture to evaporate efficiently.
-
Cyclone Separation & Purification: The mixture enters a cyclone separator. Here, cool air helps condense remaining moisture while centrifugal force separates the heavier, dry plastic from lighter impurities like dust and fines.
Key Benefits of Our High-Efficiency Plastic Drying System
Achieve Premium Quality
Consistently hit moisture levels below 3% (and even below 1% with sequential systems) to produce top-grade, high-value recycled pellets.
Increase Material Purity
The integrated cyclone separator actively removes contaminants like dust and fines, enhancing the overall purity of your final product.
Boost Production Efficiency
Dry, clean material runs smoothly through extruders, significantly reducing processing issues, downtime, and maximizing your throughput.

Need more power? For larger operations or materials requiring ultra-low moisture levels, we offer larger models and can design systems with multiple thermal heaters in sequence to meet any throughput requirement.
Frequently Asked Questions (FAQ)
What’s the main difference between dewatering and thermal drying?
Dewatering is a mechanical process (like a centrifuge) that removes bulk surface water, typically getting moisture down to 5-15%. Thermal drying is a thermal process that uses hot air to evaporate the remaining, more stubborn moisture to get below 3%. They work together: dewatering first, then thermal drying for a final, high-quality result.
What final moisture level can I expect?
Our standard thermal drying machine is designed to consistently achieve a moisture content of less than 3%. For applications requiring even lower levels (e.g., below 1%), we can configure a system with multiple drying units in series to meet your specific target.
What types of plastic can this machine handle?
Our thermal dryers are highly versatile and are successfully used for a wide range of washed plastic materials, including:
- Rigid plastic flakes (e.g., PET, HDPE)
- Soft plastic films (e.g., LDPE, LLDPE, PP film)
- PP woven bags and other similar materials.
How does the cyclone separator improve quality?
The cyclone separator is crucial for purification. As the material and air swirl inside, centrifugal force separates particles by weight. The heavier, dry plastic flakes fall to the bottom for collection, while lighter contaminants like dust, labels, and fine particles are carried out by the air stream and collected separately. This results in a much cleaner, purer final product.
Do you offer customized solutions?
Absolutely. We know a one-size-fits-all approach doesn’t work. We can customize the heating power, pipe length and diameter, and overall system size based on your material type, required throughput (kg/hr), and target moisture level. Contact us to discuss your project specifics.
