Material handling gains deliver greater precision
The nature of compounding operations is that a very wide range of materials need to be handled efficiently and effectively. Fortunately, suppliers of all types of materials handling equipment are continuing to make improvements in accuracy, ease of use, and reliability and several now also open the doors of their laboratories to let custom- ers try out new solutions before making a purchase decision. This article takes a look at some of the latest developments. DPK is Moretto’s latest loss-in-weight feeder, which is said to be well suited for the dosing of small quantities of colorant or additives into a wide range of base materials. The company says the unit offers extremely accurate dosage control, even at very low rates, while the hardware and software together – the load cell technology and control algorithm – are claimed to make the DPK virtually immune to vibrations. This helps achieve improved dosage precision. In the DPK unit, the colorant masterbatch or additive to be dosed is contained in a hopper with transparent shock-resistant acrylic walls, which makes for easy viewing of the material level. The hopper is also easily removed with no tools for replenishment or additive changeover. The DPK unit features a simple touch screen interface from

which it is possible to store and recall individual recipes. It also offers Ethernet and RS485 connec- tions and is prepared for MOWIS (Moretto’s self-configurable integrated supervision and management system that uses object-oriented programming tools). MOWIS enables remote control of complex systems in real time, allowing supervision of plant status and of each connected device. It has dedicated modules for conveying, drying, dosing, storage, and cooling.
Gravimetric options With its Spectroflex V dosing system, Motan-Color- tronic makes it possible for volumetric and gravi- metric dosing to be combined on a single unit platform in its product line for the first time. Spectro-
