How to Work


>>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 pellets will have a fast heating till the temperature rises to the preset temperature.

>>Drying &Crystallizing step

Once the material gets to the 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 drying. Then the drum rotating speed will be slowed down again. Normally the drying process will be finished after 15-20mins. (The exact time depends on the property of material)

>>After finishing the drying 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.

No segregation of products with different bulk densities
Independent temperature and drying time set
Easy clean and change material

Instant start-up and quicker shut down
Uniform crystallization
No pellets clumping & stick
Carefully material treatment

Machine Application

Heating. Heating granules and regrind material prior to further processing (e.g. PVC, PE, PP,…) to improve throughput in the extrusion process.
Crystallization Crystallization of PET (Bottle flakes, 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.
High-input moisture Drying processes with high input moisture >1%
Diverse Heating processes for the removal of rest oligomers and volatile components.
