Not only for masterbatch crystallisation and drying Kreyenborg will also be show- ing an IR-Batch 90/100-30. Exactly like the continuously working infrared rotary drums, the discontinu- ously working IR-Batch is claimed to ensure a gentle while efficient treatment of the material. Whether the task is heating-up, crystal- lising, drying or coating of plastics pellets, the IR-Batch is flexible and versatile. It is not only suitable for process- ing plastic materials, but also chemical products and foodstuff. The IR-Batch has become established world- wide in PET masterbatch drying processes, says Kreyenborg. This is due to its two key features of convenient process control and flexibility. Drying of PET masterbatch is only possible if the polymer crystallises simultaneously, because otherwise undesired pel- lets agglomerations could form. Therefore, the drum of the drying unit is equipped with incorporated mixing elements. Owing to a very precisely and individually adjustable temperature control, the pellets can be crystallised gently, as well as safely. The heat input by the infrared radiation is direct, so that short process times of just 15 to 20 minutes are guaranteed. As cleaning of the process unit is of major importance, the company ensured easy accessibility and quick material changes. The IR-Batch can be opened completely and the infrared module can be moved out of the rotary drum on an extraction unit. processing times of 10 to 20 minutes. The IR-Batch 90/100-30 will be exhib- ited at K’2019; it will be equipped with a big sight glass for demonstration purposes. It has a diameter of 90 cm, a length of 100 cm and is suited for a filling quantity of 40 kg. www.kreyenborg.com Due to its simple structure, the drum does not have any concealed or poorly accessible areas and is there- fore very simple to clean by means of a suction device or compressed air. After cleaning, the system can be used again immediately without any pre-heating. IR-Batch units are available with filling volumes in the range of 60 to 300 dm³, which cover a throughput range between 150 and 500 kg/h in
