Moretto has announced the latest addition to their family of high performance mini-dryers for treating small batches and engineering resins.

The X-Comb mini dryer has been specifically engineered for use by the medical industry where stringent requirements on performance and design are compulsory. The X-Comb mini dryer packs a wealth of Moretto industry leading technologies into a compact design and is available in four sizes ranging in throughput from 1.4-14.4 kg/h.

“The X-Comb dryer brings together some of our most innovative technologies in developing a revolutionary dryer that again proves we are challenging the status quo. We engineered this dryer to be medical ready, Industry 4.0 compliant, and all the while optimizing energy consumption for small batch and engineering resins”, said Benjamin Sutch, CMOfficer, Moretto.

Immediately obvious upon first inspection is the inclusion of Moretto’s patented OTX hopper technology. OTX takes a radical new approach to drying hopper technology utilizing a unique internal geometry that significantly improves material mass flow and air flow distribution throughout the hopper. Beyond the signature Spyro shock-proof casing is a hopper capable of treating the same material as conventional hopper designs whilst requiring 40% less hopper volume, drying time, and airflow.

At its core, the X-Comb dryer features an integrated dew point equalizer that manages the speed and revolution of a zeolite based desiccant cartridge. A direct drive geared motor drives the cartridge rotation and can achieve a stable -52°C dew point.

Powering the X-Comb are two, high performance, VFD driven turbo-compressors; one compressor dedicated to the process circuit while the second manages the regeneration cycle. Add to this a self-adjusting variable air-flow and resin anti-stress control, which together ensure optimal drying while never over-drying. The dryer’s filter has been positioned externally and can be easily accessed, without tools, for cleaning. The regeneration exhaust air can be channeled ensuring that the dryer is suitable for medical and other clean-room, optical, or technical applications.

An integrated colour touch-screen control comes standard with either model of the X-Comb series. The simple and easy to use interface allows for quick selection and control of all dryer parameters. In addition, the control has been adapted to centrally manage an optionally connected Moretto Venturi feeder. Standard RS485 Modbus, Ethernet and USB connectivity options are available and the dryer is compatible with Moretto’s Mowis plant-wide supervisor system.

The X-Comb mini dryer series has been further developed under the umbrella of the Moretto Drying 4.0 initiative, which sees Moretto ensure that their full range of machine auxiliary solutions are Industry 4.0 ready.

The compact design of the X-Comb mini-dryer makes it well suited for installation on either the injection machine throat or located machine side.  Discharge bases and portable trolleys can be further integrated with the dryer.
