TPEE Dryer & VOC Cleaner

Short Description:

Infrared Drying system for Polymer Devolatilization

The infrared preheating devolatilization system mainly heats the materials entering the heating host through specific infrared radiation. When the material reaches the set temperature, it enters the vacuum devolatilization module for vacuum devolatilization treatment, and the volatile phenol released by the heated material is discharged.

>>High timeliness and fast devolatilization

>>Dynamic drying mode, heating evenly. Excellent material flow, no agglomeration

>>High efficiency and energy saving, saving more than 60% of energy consumption

>>The content of volatile phenol in the output material is less than 10ppm

>>Simple structure, easy to clean, quick product change

Final moisture	30ppm Tested by German Sartorius Moisture test instrument
Final product	Dried TPE no clumping, no pellets sticking

How to Work

>>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 PETG pellets will have a fast heating till the temperature rises to the preset temperature.

>>Drying 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 to vacuum devolatilization system for VOC Removing

>>Devolatilization system for VOC Removing

The infrared devolatilization system mainly continuously heats the material through the infrared radiation with specific wavelength, while the material is heated up to a preset temperature, the dried material will be fed to Vacuum devolatilization system for repeated vacuumization devolatilization, finally the volatiles which are released by heated material are discharged by Vacuum system. And the Volatile matter content can be <10ppm

Our Advantage

1	Low energy consumption	Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product
2	Minutes instead of hours	The product remains for only a few minutes in the drying process and is then available for further production steps.
3	Instantly	The production run can start immediately upon startup. A warm-up phase of the machine is not required.
4	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.
5	In one step	Crystallization and drying in one step
6	Increased throughput	Increase of plant throughput by means of reduced load on extruder
7	No clumping, no sticking	The rotation of the drum ensures constant movement of the material. The spiral coils and mixing elements designed for your product ensure an optimal mix of material and avoids clumping. The product is evenly heated
8	Siemens PLC control	Control.The process data, such as material and exhaust air temperature or fill levels are continuously monitored by means of sensors and pyrometers. Deviations trigger automatic adjustment. Reproducibility.Recipes and process parameters can be stored in the controlling system to ensure optimal and reproducible results. Remote maintenance.Online service via modem.
