Infrared Crystal Dryer For Polyester Masterbatch Drying and Crystallization

Infrared crystal dryer continuous processing

What we can do for you

Final moisture 30-50ppm,save 45% energy cost

Drying and crystallization at a time. Drying time only needs 20mins.
Save about 45-50% energy cost compared with conventional dehumidifier.

Easy to clean, change material, colour

The drum with the simple mixing elements has no hidden spots and can be cleaned easily with a vacuum cleaner or compressed air. This enables the operator to have a very quick change from one material to another and alsp the masterbatch colour.

No clumping

Rotary drum design to avoid any clumping of the material and assure a very good cross mixing of the material.

Adopt Siemens PLC control

Recipes and process parameters can be stored in the controlling system to ensure opimal and reproducible results.

Infrared Crystal Dryer

The infrared rays caused molecular heat oscillation acting directly to the core of the particles from the inside-out, the moisture inside the particle are quickly heated and vaporized into the circulating ambient air to remove the humidity at the same time.

How to work

Infrared crystal dryer continuous processing

Processing Explanation

1) At first step, the only target is to heat up the material to a preset temperature.

Adopt relatively slow speed of drum rotating, the Infrared lamps power of the dryer will be at a higher level, then the PET Masterbatch will have a fast heating till the temperature rises to the preset temperature.

2) Crystallization step

Once the material gets to the critical crystallization temperature, the speed of the drum will be increased to a much higher rotating speed to avoid the clumping of the material. At the same time, the infrared lamps power will be increased again to finish the crystallization. Then the drum rotating speed will be slowed down again. Normally the crystallization process will be finished after 15-20mins. (The exact time depends on the property of material)

3) After finishing the crystallization processing, the IR Drum will automatically discharge the material and refill the drum for the next cycle.

The automatic refilling as well as all relevant parameters for the different temperature ramps is fully integrated in the state-of-the-art Touch Screen control. Once parameters and temperature profiles are found for a specific material, theses settings can be saved as recipes in the control system.


Heating.Heating granules and regrind material prior to further processing (e.g. PVC, PE, PP,…) inter alia to improve the throughput in the extrusion.

Crystallization.Crystallisation of PET (Bottleflakes, granules, flakes), PET masterbatch, CO-PET, PBT, PEEK, PLA, PPS, etc.

Drying.Drying of plastic granules, and –ground material (e.g. PET, PBT, ABS/PC, HDPE, LCP, PC, PP, PVB, WPC, TPE, TPU) as well as other free-flowing bulk materials.

Coating.Coating of adhesives (e.g. Hot melt, EVA+lime,…)

High input moisture.Drying processes with high input moisture >1%.

Diverse.Thermal processes for the removal of rest oligomeren and volatile components.


In order to ensure the accuracy of each part, we are equipped with a variety of professional processing equipment and we have accumulated professional processing methods over the past years.

Each component before assembly needs strictly control by inspecting personnel.

Each assembly is in charged by a master who has working experience for more than 20 years.
