Product Description

Pre-crystallization and dryer for PET chips/scraps/pellets for PET /PLA Sheet extrusion machine line 


Pre Crystallization 70ppm Infrared Rotary Dryer 0



Infrared drying technology offers the ability to dry and crystallize materials in minutes, compared to hours with conventional drying equipment which reduces change over times significantly and reduces energy consumption at almost 45%, Also Infrared drying technology changes in moisture at beginning will dry pellets gently to a uniform degree within minutes, the final moisture can be 30-50ppm


Field of applications.

Heating.Heating granules and regrind material prior to further processing (e.g. PVC, PE, PP,…) inter alia to improve the throughput in the extrusion.

Crystallization.Crystallisation of PET (Bottleflakes, 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.

Coating.Coating of adhesives (e.g. Hot melt, EVA+lime,…)

High input moisture.Drying processes with high input moisture >1%.

Diverse.Thermal processes for the removal of rest oligomeren and volatile components.


Our processing


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


l Limiting the hydrolytic degradation of the viscosity.

l Prevent increasing AA levels for materials with food contact

l Increasing the capacity of the production line up to 50%

l Improvement and make the product quality stable-- Equal and repeatable input moisture content of the material



Pre Crystallization 70ppm Infrared Rotary Dryer 1

1. Material  Filling

By vacuum dosing feeder to convey the raw material continuously to the rotating drum



2. Drying and Crystallization

Thermal treatment and mixing. There are the spirals welded into the rotary drum to ensure the well mixture of material and continuous transfer to the outlet. And the material will also be dried continuously


3. Discharging

The dried and crystallized material will be discharged after minutes drying by drum rotary. Finally the dried and crystallized material will be conveyed to the next processing.






IRD Dryer

Traditional 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 hoursdehumidifier 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.


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.



Power Consumption 


pprox. power consumption A-PET 0.08 KW / KG,HR (Crystallization only)
C-PET 0.12 KW / KG,HR (Drying only)
FLAKE 0.20 KW / KG,HR (Crystallization & drying)

Advantages for your process.

Low energy consumption.Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product.

Minutes instead of hours.The product remains for only a few minutes in the drying process and is then available for further production steps.

Instantly.The production run can start immediately upon startup. A warm-up phase of the machine is not required.

High efficiency.The energy is immediately brought into the core of the product.

Gently.The material is heated gently from the inside to the outside and not loaded from the outside for hours with heat, and thereby possibly damaged.

Easy cleaning.Good access to all components allows for easy and fast cleaning. Rapid product change-over.

In one step.Crystallization and drying in one step.

Increased throughput.Increase of plant throughput by means of reduced load on extruder.

Evenly.Ensures a constant discharge.
