professional factory for 3d Printer Filament Dryer - PET Flake/scrap dehumidifier crystallizer/Infrared Rotary Dryer/Plastic dehumidifier/ Plastic Desiccant Dehumidifier/Plastic dryer/Infrared crystal dryer – LIANDA Detail:

Application Sample

Raw Material	PET Recycled flake/ PET sheet scrap/PET Preform scrap
Using Machine	LDHW-600*1000
Drying& Crystallized Temperature set	180-200℃Can be adjustable by property of rawmaterial
Crystallized time set	20mins
Final material	Crystallized and Dried PET scraps and final moisture can be about 30ppm

How to Work

Feeding/Loading

Dry& Crystallization Processing

Discharging

>>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.

Our Advantage

Normally the PET Bottle flakes or sheet scrap with initial moisture level of up to 10000-13000ppm. The PET Bottle flakes or sheet scrap (Virgin or mixed ) will be recrystallized in Infrared crystal dryer in 20mins, the drying temperature will be 150-180℃ and dried to 50-70ppm,then fed to Single screw extruding system for further processing

● Limiting the hydrolytic degradation of the viscosity.
● Prevent increasing AA levels for materials with food contact
● Increasing the capacity of the production line up to 50%
● Improvement and make the product quality stable– Equal and repeatable input moisture content of the material

Comparison Table

Item	IRD Dryer	Conventional Dryer
Transfer medium	None	Hot air
Heat transfer	Both inside & outside particles together.	From outside to inside particle gradually.
Energy	Save at least 20~50% energy compared to traditional dryer.	Consume much energy.
Process time	1. Crystallization & drying: They are processed simultaneously within about 8~15 minutes. 2. Drying and crystallization at a time	1. Crystallization: About 30~60 minutes. 2. Drying: About 4~6 hours.
Moisturecontent	1. Under 50-70 PPM after IRD processed.	1. Spend 30~60 minutes to change amorphous PET to crystallized PET first. 2. Under 200PPM after about 4 hours dehumidifier processed. 3. Under 50 PPM after about more than 6 hours dehumidifier processed.
Lead time	20mins	More than 6 hours.
Material changeover	1. Easy & faster. 2. There are only 1~1.5 times capacity of material hourly consumption in the buffer hopper.	1. Difficult & slowly. 2. There are 5~7 times capacity of material hourly consumption in the crystallizer & hopper.
Operation	Simple— By Siemens PLC control	It is difficult such as it must put a little crystallized PET in the crystallizer when beginning operation.
Maintenance	1. Simple. 2. Lower maintenance cost.	1. Difficult. 2. Higher maintenance cost.
