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.
