EVENT REVIEW PETplanet Insider Vol. 25 No. 07+08/24 www.petpla.net 38 the process variables, the XD 20 also adapts the treatment to each polymer and the CRX Mobilux has an antistress device to prevent overdrying of the granules. The VFD automatically adapts to the actual throughput and is therefore designed to guarantee perfect drying and prevent over- or under-drying of the resin. As an option, the Mobilux drying systems can also be equipped with Moretto’s inline moisture meter, which is connected directly to the drying system’s control unit and whose moisture sensor is located directly under the drying hopper. It guarantees real-time control of the drying process to minimise waste, reduce energy consumption and avoid human intervention. The manufacturer also launched the DGM 20 Gravix, the latest model in the already well-known DGM gravimetric multi-component mixer series with its proprietary Roto-Pulse technology for precise mixing and waste minimisation. It is said to be specially designed for small components where low throughput and high mixing accuracy are required. Equipped with double flap valves, the system offers precise material dosing of raw materials, masterbatches and additives. The capacity is up to 20kg/h. The demountable design is said to greatly simplify cleaning and maintenance, without the need for tools. The system is also designed for uncomplicated and rapid material changes and adjustments. Control can be systemintegrated and via a touchscreen on the device. www.moretto.com Flexible material drying and dosing systems In addition to its established products, Moretto also presented its CRX Comb series of Mobilux dryers for the first time. This compact series is based on the X Comb and is available in models with different drying. According to the manufacturer, each CRX Comb model features a honeycomb wheel of 100% zeolite desiccant and is equipped with anti-stress technology to prevent over-drying, as well as automatic drying air modulation for optimal drying performance with minimal energy consumption. Part of the anti-stress technology is the adaptation of the air flow to the drying requirements while maintaining the same drying quality. As a special feature, the parameters material type and throughput are required, while the dryer automatically regulates all other parameters such as dwell time, process temperature, air flow and anti-stress and processes all polymer types correctly. By using an exclusive zeolite desiccant, continuous dew points of -62 °C are achieved. The CRX Comb works with a single power supply, so no compressed air or water is required. The technology, based on the X Comb, includes Moretto’s OTX (Original Thermal eXchanger) hopper, whose dehumidification process and concept is said to realise a true exchange of energy and moisture with optimal energy efficiency, resulting in a 40% shorter drying time and a 40% reduction in hopper volume with the same throughput and, thanks to the internal geometry, is said to improve energy efficiency by 66%. The company offers the range of CRX Mobilux drying systems based on XD 20 dryers, which are equipped with a double tower drying system that can generate uniform -75 °C dew points. Unlike other twin tower dryers on the market, the XD 20 series features a variable frequency drive (VFD) controlled fan to modulate the airflow to the hopper to meet performance and energy reduction standards, Moretto said.
