PET Masterbatches crystallization by Infrared crystal dryer
How Lianda Infrared dryer to crystallize PET Masterbatch ?
1. Working processing of Masterbatch Infrared dryer
Processing Explanation
1) At first step, the only target is to heat up the material to a
presettemperature.
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.
