Drying systems for granulates and powder
Whether surface moisture, capillary moisture or crystal humidity – each product has its own requirements of the drying. The following applies: With Ebbecke Verfahrenstechnik AG your contract drying is in the best of hands, because we dry granulates and powder carefully according to the specific requirements. On request we can even develop new and innovative drying processes for you.
System diversity as a basis for a perfect result
With the selected drying process, our process engineers take into account for example the temperature sensitivity, resistance to ultraviolet radiation (infrared radiation), the surface structure and the capillary structure of the product which is to be dried. Of course, the differences in the output moisture content and the desired residual moisture must be included in the procedural evaluation of an efficient drying.
However, not every drying system is suitable for every material which is to be dried. To get a perfect result, we use various drying systems accordingly. Available to our customers are fluidized bed dryers, drying ovens, conveyor dryers and vacuum dryers. Furthermore, innovative infrared dryers and microwave dryers are used, which play an important role for our customers in the food chemistry and pharmaceutical industries.
With drying, the exact determination of the moisture content forms the indispensable foundation for a constantly low residual moisture. In order to obtain meaningful data, the Ebbecke Verfahrenstechnik AG engineers use a variety of measuring procedures. Several precise working measuring systems and procedures are available, for example the coulometric Karl Fischer titration and other systems based on the procedures of Karl Fischer. In addition, Sartorius moisture analyzers and the computerized FMX HydroTracer system are used.
In our cutting-edge plants target humidities of up to 0.02% can be realized depending on the product. But even the best drying rate is useless if the expertise is lacking in the subsequent handling of the dried goods. More specifically: The dried product must be protected from re-absorption of humidity. At Ebbecke Verfahrenstechnik AG this is done by overlaying with nitrogen and through the use of plastic or aluminum liners. In addition to this the dry material may be further dried in a exsiccator.
