Hot wash for recycling

Among the recent innovative developments by Reg-Mac (hall 09, stand D52 at the K 2013 show), the Hot-Wash system suitable for PET/HDPE flakes is the most significant. Such a process is carried out by two independent units where flakes are automatically loaded and alternately treated in both chambers, thus resulting in a continuous working process with two separate feedings. This Hot-Wash unit features significant improvements, which include further control instruments integrating the standard ones.
Chemicals are automatically dosed on the basis of working parameters established time by time according to incoming PET quality. After chemical treatment, liquids are extracted by a specific filtration system and PET flakes are then fed into an intensive rinsing system. Process controls have also been improved, becoming more functional by means of a touchscreen instrument, which allows the operator to follow and modify parameters as needed. The electronic control system is entrusted to next generation Siemens components. The whole process is customized according to the final application of the PET clean flakes: bottles, sheets, fibres, strapping bands etc.
Hot-Wash and Cold-Wash lines are available in 4 models, offering a treatment capacity from 600 to 2,500 kg/h.
