Automations for a proper drying: DRÄGER brings advanced Moretto technologies
Why is plastic granule drying key to production quality?
Even when using high-quality materials, production results can be unstable. The inadequate material preparation, under or over dried phenomena, a residual moisture in plastic granules can negatively affect both processing and the final properties of the product. Hygroscopic polymers, widely used in today’s technical applications, must be properly treated prior to processing to guarantee excellent plastic handling and remove excess moisture. Moretto offers a full range of auxiliary solutions targeted specifically for perfect drying.
Modern plastic drying technologies: OTX hopper, X Comb dryer and Moisture Meter control
In an environment of increasing demands on quality and efficiency, modern drying technologies have become an essential part of competitive manufacturing.
The OTX technology (Original Thermal eXchanger) fundamentally changes the approach to plastic drying. It is based on a detailed analysis of material behaviour inside the hopper, optimizing its internal geometry and thermodynamics so that each granule is exposed to identical process conditions. The result is not only improved drying quality but also significantly reduced energy consumption.
Key benefits of OTX technology:
- up to 40% reduction in drying time
- approximately 40% reduction in hopper volume
- up to 66% improvement in energy efficiency
- uniform drying of the material
- optimized heat and moisture transfer within the process.

When processing hygroscopic polymers, it is essential to ensure not only homogeneous dehumidification, but also energy efficiency and compact structure. X Comb is the compact and full electric dryer that combines advanced dehumidification technologies with a high level of automation and flexibility, ensuring stable performance even under fluctuating production conditions. The system achieves a stable dew point from -52 °C to -60 °C, providing optimal conditions even for demanding technical materials.
Main features of the X Comb dryer series:
- zeolite molecular sieves for efficient moisture adsorption
- Hyper Flow turbo compressors for high performance and efficiency
- low energy consumption with adaptive airflow control
- high level of automation.

A primary challenge in drying is defining the moisture content of the granules before entering the transformation process. This information helps avoid under or over drying phenomena and reduce products’ defects and energy waste. The Moisture Meter control provides continuous monitoring of residual moisture and verifies that the material has reached the required condition before processing. The Moisture Meter control measures moisture content in real time, eliminates the influence of ambient conditions and enables immediate process optimization.

The integration of OTX hopper, the X Comb dryer and real-time moisture measurement with the Moisture Meter control allows manufacturers to achieve higher quality, lower costs and, above all, better control over the entire drying process.
