Extrusion International 5-2018

PREVIEW 46 Extrusion International 5/2018 veloped to guarantee adequate levels of dehumidifica- tion, granulation and dosage of the polymer. These are ideal conditions to allow processors to obtain a high qual- ity final product. Everything under control of Mowis 3, the integrated self- configurable supervision systemwith intuitive object pro- gramming, developed by Moretto for the connection and control of the whole automation chain in plastics process- ing plants. Mowis 3 overcomes the barriers of traditional supervi- sion by adapting to the needs and the qualitative, pro- ductive and managerial objectives of every customer. It’s a modular software with unique, auto-configurable and user friendly interface which allows immediate display of the system status. With Mowis 3, the integrated process control is easily managed from any location, on-site or re- mote. Based on SCADA system, Mowis 3 allows a safe and immediate exchange of data between standard modules, taylor-made modules and the customer management sys- tem. Moretto’s drying solutions are suitable both for complex models such as multi hopper systems and for the dehu- midification of small quantities of technical materials, like X Comb mini dryers, designed to meet the requirements of the most demanding sectors such as the medical, with- out the use of compressed air. X Comb guarantees maxi- mum efficiency and reliability thanks to the zeolite tech- nology, the powerful turbo compressors, the exclusive OTX hopper and the dew point equalizer (up to -52°C). The compact dryers of the X Dry Air series, equipped with a double-bed system with zeolite technology and a trans- parent OTX Pyrex hopper, ensure even higher perfor- mance by reaching dew point values up to -70°C. For multi hopper plants, the best drying solution is the revolutionary EUREKA PLUS system, “the most advanced low consumption drying system available on the market- able to reduce energy consumption by 56% compared to conventional drying systems. Eureka Plus consists of four Moretto-patented technologies: • X MAX, the only high performance multi-bed modular dryer • FLOWMATIK, a dynamic airflow management system, • OTX, innovative hoppers with an exclusive internal ge- ometry • MOISTURE METER MANAGER, the revolutionary device which measures polymer residual moisture in-line and adapts the drying system operations. By working together, these four automations provide an “on demand” self-adjusting, modular and energy-saving drying system. Moisture Meter Manager, thanks to the sophisticated Box, Crown and Control devices, can detect in-line the in- trinsic moisture in the polymer with an extraordinary level of precision: from 3,000 up to a minimum of 15 parts per million (ppm), with a degree of precision of ±3 ppm and a temperature range from 20 to180°C. Moisture Meter Manager is a real “intelligent” device, it automatically directs the drying system to adjust its dry- ing parameters to match the drying requirements, assur- ing that material is perfectly dried using the minimum amount of energy. WithMoistureMeter Manager we talk about “drying on demand” by targeting the actual mois- ture levels of the resin and not simply providing the same drying heat and airflow for all conditions. At Fakuma great attention is also dedicated to the dosing phase, with the presentation of DPK, the new compact loss-in-weight dosing unit, suitable for intermittent or continuous dosing of small quantities of color or additives into a flow base material, that solves the problem of over- dosing with an extremely precise control. Thanks to the exclusive vibration immunity system, the machine control algorithm and the hopper removeable from the dosing unit, DPK achieves a dosing accuracy up to ±0,03%, allow- ing processors to avoid unnecessary wastes of expensive additives. Among Moretto’s innovations presented at Fakuma 2018, there are certainly three new types of maintenance hoppers, valid solutions for the containment of plastic granules on the processing machines. The TM hoppers made of stainless steel and with a characteristic cone shape, guarantee an optimal flow of any material, and are suitable to accept single- phase, three-phase and receivers for centralized con- veying systems. The TMC hoppers are used for the treatment of dried hot materials. Realized in stainless steel, they feature the dou- ble-wall insulation with removable cone that avoids heat loss by creating a process constancy. Krystal maintenance hoppers (TMK) are made of trans- parent shockproof acrylic material, they ensure an ef- fective containment of plastic granules and offer a great visibility allowing the operator to immediately verify the level of material. The Dolphin distribution manifolds, the Kruise Kontrol speed control and the suction units with cyclone filter are all machines controlled by the One Wire 6 software, the “intelligent conveying system” developed by Moretto.
