A: The frequency of infrared is about 1012 C/S ~ 5x1014 C/S, which is part of electromagnetic wave. Near infrared wavelength is 0.75~2.5μ and travels straight at the speed of light, and it goes around the earth seven and a half times per second (about 300,000 Km/s). It can be seen from the light source It is directly transmitted to the material to be heated, causing physical phenomena of absorption, reflection, and transmission.
The infrared crystal dryer is the latest drying technology developed at present, and the infrared crystal dryer only needs 8-20 minutes, crystallization and drying are completed at one time, saving time, electricity, good drying effect, convenient maintenance and low cost, which is the highest efficiency at present , The best choice for low energy consumption drying method.
A: The drying temperature can be adjustable by material’s drying requirement. Adjust scope: 0-350℃
A: Depends on material’s initial moisture and final moisture you want to get.
For example: PET sheet scrap Initial moisture 6000ppm, final moisture 50ppm, drying time needs 20mins.
A: No. It will not affect the viscosity of PET
A: Will be like milk colour
A:Yes
A: Different drying temperature adopting while PETG produced by different manufacturer. For example: PETG k2012 produced by SK Chemical, the drying temperature of our IRD is 105℃, drying time needs 20mins. Final moisture after drying is 10ppm (Initial moisture 770ppm)
A: Yes, we have the test center to supply free testing
A: Drying temperature can be set according to the characteristics of the raw materials.
The temperature set scope can be 0-400℃ and the temperature will be set on Siemens PLC screen
A: Infrared temperature camera ( German Brand) to test the material temperature. The error will not exceed 1℃
A: We have Both types. Usually the continuous IRD, the final moisture can be 150-200ppm. And the Batch IRD, the final moisture can be 30-50ppm
A: Usually 20mins.
A: It can be pre-dryer for
