PET Masterbatches crystallization by Infrared crystal dryer
IRD Technology are often used in PET Application such as
Thermoforming sheet, Strapping, Cast film and recycling production
LIANDA has designed 2 types of Infrared crystal dryer to satisfy
different customers’ requirement on the crystallization of PET
Masterbatch. One is Continuous IRD which can satisfy the companies who run rather large capacity of
plastic masterbatches and don’t change the color very often.
Another is Batch IRD which can satisfy the companies who run smaller capacity like
80-200kg/h with frequent color change. Such type design supply the proper and sufficient cleaning as well as quick
start up times.
The ADVANTAGES of IRD crystallize PET color masterbatch
Infrared Crystal Dryer | Conventional Crystallizer | |
| 1 | Easy to clean and change color | Have to be completely disassembled,cleaned and fixed |
| 2 | Rotary drying system, its rotating speed can be increased as high as possible to get an excellent mixing of pellets. It is good in agitation, the masterbatch will not be clumped | Poor agitation,easy to be clumped |
| ||
| 3 | Can satisfy different type of Masterbatch (Drying temperature and time can be adjustable by the property of raw material) | The drying temperature is fixed |
| ||
| Infrared rotary dryer is designed with sophisticated temperature measurement. The material and exhaust air temperature are continuously monitored by sensors. If there is any deviations,PLC system will adjust automatically | ||
Recipes and process parameters can be stored in the controlling
system to ensure opimal and reproducible results | ||
| 4 | Crystallization time 15-20mins depends on the material kind | Need 2 hours or more |
| 5 | Energy consumption of Infrared dryer is only 1/3 of Convention crystallizer | |
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
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.
