The Infrared Drying Technolgy offers the ability to dry and crystalize materials in minutes compared to hours with conventional drying equipment which reduces change over times significantly and reduces energy consumption drastically.

The KREYENBORG IR Dryers can heat, dry and crystalize in one-step

The heating of pellets and/or and regrind (PVC, PET, PE PP etc.) prior to extrusion helps to significantly increase the capacity of the downstream equipment.

When PET, PLA PEEK, PPS, PBT or other materials are processed on the Kreyenborg IR the material can be crystalized in the same step. Even so the process has a short residency time compared to conventional dryers the material can be dried from >1% moisture to less then 300 PPM within 15-20 Minutes.

The IR Process also allows the coating of adhesives in the system (Hot melt, EVA and lime etc.)

Through this Thermal process it is possible to also remove volatiles from the material that is dried. The IR-CLEAN® Super-Clean recycling process. With the IR-CLEAN® system, KREYENBORG offers an attractive and cost-effective alternative for the direct reprocessing of PET post-consumer flakes for food packaging. This process has been awarded a LNO from FDA and is also EFSA compliant

The KREYENBORG Infrared Dryer Function

The energy is instantaneously brought into the core of the product by short-wave infrared radiation. The heat flow pushes the moisture from the inside towards the outside of the material ensuring a homogenous drying of the material inside out. Since the material is constantly in motion the evaporated moisture is immediately taken away from the rotating drum. The constant motion also exposes huge Surface area of the material to the IR Radiation which ensure an instant heat up process

The rotating drum has an internal spiral that is equipped with mixing elements ensuring a constant mixing process that avoids any material clumping and furthermore ensure that the material is heated evenly throughout the process. Combined with low rotational speed of the drum the material will not be damaged throughout the process. The speed of the process and the final moisture content of the product can be adjusted by the rotational speed. All functions are controlled through a simple HMI, that allows the storage of recipes and monitors exhaust air temperatures, fill levels etc. The system will self adjust if parameters will deviate from the set points.

The IR-Radiator module

The Kreyenborg radiator module has been specifically developed for the Infrrared dryer and has been thermally and fluidic optimized for the process. It is continuously by the airflow through the dryer. A special ceramic ensures optimum utilization of infrared light which increases the efficiency of the technology. To protect the IR Radiators from moisture, dust particles etc. Kreyenborg has developed an Air-Shield around it.

Kreyenborg offers continuous and batch processing IR Dryers

For large scale production environments, the continuous process is ideal since it ensures production without interruption. In this process the equipment is automatically filled by a volumetric dozing system. Throughout the rotating drum the material is evenly mixed and thermally treated. The process takes only minutes compared to conventional drying methods that take hours.

We offer systems with capacities that range from 50 lbs/hour to 11,000 lbs/hour.

  • For lower capacity applications Kreyenborg offers a batch process as well.
  • Advantages for your process.
  • Low energy consumption.
  • Minutes instead hours.
  • Instant Heat
  • High efficiency
  • Gentle
  • Simple Changeover and maintenance

  • Increase capacity for downstream equipment

KREYENBORG IR BATCH

Discontinuous heating, crystallization, drying and coating of batches of different plastics and other bulk materials in minutes instead of hours.

Ideal solution for thermal treatment of single batches.

The machine operates in batch mode which means that an entire batch of material is loaded at once into the system Once the processing time is elapsed the batch is discharge from the drum by reverting the rotational direction

Application examples:

  • Drying and Crystalizing of PET to 50 PPM
  • Drying and Crystalizing of PLA
  • Drying and Heating of PE Pellets to remove volatiles
  • Crystallization of Masterbatch in small batches

KREYENBORG IRD

KREYENBORG IR CLEAN

IR-CLEAN® Super-Clean recycling process. With the IR-CLEAN® system, KREYENBORG offers an attractive and cost-effective alternative for the direct reprocessing of PET post-consumer flakes to food grade.

High-Performance Decontamination

Efficient decontamination of recycled PET for re-use in direct food contact packaging.

PET – PROCESSING WITH IR-CLEAN®

With the IR-CLEAN® system, KREYENBORG offers an attractive and cost-effective alternative for the direct reprocessing of PET post-consumer flakes for food packaging – without using any vacuum technology and as a retrofit solution for existing extrusion lines. The efficiency of the cleaning process has been verified by a Letter of Non-Objection from the US Food and Drug Administration (FDA). Similarly, several challenge tests have demonstrated compliance with the criteria established by the European Food Safety Authority (EFSA) for the use of recycled materials for direct food contact packaging.

Application examples:

Drying, Crystalizing and decontamination of PET for food-contact pellets or sheets
