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 PET 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 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

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.
9 Drying time only needs 20mins, final moisture can be ≤ 30ppm The infrared rays that penetrate and reflect from the material do not affect the organization of the material, but the absorbed tissue will be converted into heat energy due to molecular excitation, which causes the temperature of the material to rise.
10 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
11 Easy clean and change material Good access to all components allows for easy and fast cleaning.Rapid product change-over.
