A crucial process in PET recycling is certainly the crystallization. MPK Moretto Krystallizer, one of the exhibits at Drinktec, is a system designed to crystallize post-consumer materials - regrind and washed ready to be transformed.

Perfectly treated they can be used with virgin plastic polymers for new production processes. MPK stands out for some important features in machinery that process post-consumer material such as the drop down cone with assisted device that allows the operator to quickly proceed with cleaning and maintenance activities thanks to the easy opening which takes only two minutes. An exceptional usability factor in a machine that process critical materials such as regrind and/or flakes. The internal mixer shaft with removable blades can be easily adapted to the different treated  material. The blades have a wing profile that moves the material in a homogeneous way avoiding the formation of lumps during the crystallization phase. The hopper - with the patented stainless steel shockproof coating SPYRO – insulate the mixer body and contains the heat dispersion, increasing its energy efficiency. The control of the system processes is managed by a touch view control with a simple and intuitive interface.

MPK is a latest generation product designed for the intelligent factory, in fact it can be connected to other automations via web and remotely controlled through the supervision and management software MOWIS which achieves total connectivity via MODBUS, ETHERNET, OPC UA.

MPK is equipped with the Vortex filtration device, which intercepts the dust of the process circuit increasing its autonomy. The Purex condensate separator filters the material flow back intercepting the volatile oily and/or resinous substances contained in the vapors, impurities typically present in post-consumer materials. Purex contains emissions into the atmosphere by condensing the vapors to 99%, thus separating the vapors. Purex protects the environment and people.

Dosing is another fundamental process in the plastic transformation to obtain a quality product that respects the design specifications. Having effective equipment is therefore essential. Moretto has a wide and complete range of dosers with over 1180 models able to face any dosing request such as DGM Gravix, a batch gravimetric dosing unit that ensures complete production flexibility and high precision even in the presence of vibrations thanks to the VIS (Vibration Immunity System). MODBUS RS485, USB and ETHERNET connections allow to trace the production in real time and to certify the recipes composition. At the fair a DGM of the 900 series specific for the treatment of flakes will be exhibited.

Among the exposed equipment, there will be also a XD 800 X series dryer, an innovative drying system for large productions and specific for technical polymers such as PET. A dryer with self-adaptive technology that optimizes process conditions and reduces energy consumption up to 42%. Thanks to the variable airflow, it automatically adapts to production needs ensuring the correct supply of technological air to the material to be treated, preserving the polymer from thermal stress and viscosity variations. The innovative turbocompressor system combined with the energy recovery system from the regeneration process offers extraordinary energy efficiency. It's a one power system that does not require compressed air or cooling water for its operation. The system configuration and operator control activities are facilitated thanks to the implementation of a touch view control with a simple and intuitive interface. Programming requires to set only two parameters: material type and throughput. Once set, the machine is able to manage all the process variables automatically.
