DRYING SYSTEMS FOR GRANULATES AND POWDERS
SYSTEM DIVERSITY AS A BASIS FOR A DRY RESULT
Whether surface moisture, capillary moisture or crystal moisture – every product has its own drying requirements. Careful vacuum or spray drying is of high technical importance as an upstream process step before numerous intermediate or final products of the chemical industry are processed further.
You can be assured, your contract drying is in the best hands at Ebbecke Verfahrenstechnik AG, because we dry granulates and powders carefully according to the specific requirements. On request, we can even develop new and innovative drying processes for you.
Our company has a wide range of special equipment from different industries at its disposal to realize the variety of drying requirements and cover various particle structures. In addition to the in-house developed, very efficient vacuum drying tunnel with the possibility to dry complete production campaigns at once, we offer drying systems in different sizes with and without vacuum. Here we use systems with various hygiene standards.
Another interesting possibility is cold temperature drying and a direct melt to granulate transfer in temperature ranges from -30 to -70°C as spray solidification. In the high temperature range, spray drying is used in particular for small to medium campaign sizes from 1 to 20 tons. We have both moving and static systems, e.g. bulk trays, for our drying processes.
System diversity as the basis for perfect results
During the selection of a suitable drying process, our process engineers for example consider, the temperature sensitivity, the resistance to ultraviolet or infrared radiation, the surface structure and the capillary structure of the product to be dried. Of course, the differences in the initial moisture content and the desired residual moisture content must also be taken into account in the process engineering evaluation of efficient contract drying.
However, not every drying system is suitable for every material. In order to achieve a perfect result, we therefore use different drying systems. We offer our customers a variety of fluid bed dryers, drying cabinets, belt dryers and vacuum dryers.
Drying foods
Ebbecke also uses innovative infrared dryers and microwave dryers, which play an important role for our customers in the pharmaceutical and food chemistry industries. For many years, Ebbecke has been the main point of contact for the food industry in particular when it comes to the gentle and at the same time energy-efficient drying of food or ingredients.
This does not only require for drying parameters to be adhered to, but also that special hygiene requirements are met. Last but not least, a high-quality drying process is characterized by the fact that the food is dried gently: The aroma, the natural color, the vitamin content and the nutritional value of the goods to be dried should be preserved as well as possible.
Long-term drying
During drying, the exact determination of the moisture content forms the indispensable basis for a constantly low residual moisture content. The engineers at Ebbecke Verfahrenstechnik AG use various measuring methods to obtain meaningful data. Several precisely working measuring systems and -methods are available, such as coulometric Karl-Fischer-titration and other systems based on Karl-Fischer-methods. Other systems used include Sartorius moisture analyzers and the computer-based FMX HydroTracer.
Depending on the product, target moisture contents as low as 0.02% can be achieved on our state-of-the-art systems. But the best drying rate is of no use if the know-how for the subsequent handling of the material to be dried is lacking. I.e. the dried product must be protected from renewed absorption of humidity. At Ebbecke Verfahrenstechnik AG, this is done by superimposing nitrogen and using plastic or aluminum inner lining. In addition, the dry material can be further dried in the desiccator.
Trust
Our employees know that our industrial partners have worked hard to create product properties and process technologies. They also know that this intellectual property often forms the capital stock of a business model or a successful product. Something that applies to all drying tasks we are entrusted with. : Customer, product and contract drying data are therefore treated with the utmost confidentiality and discretion at Ebbecke. The work within the framework of the TIM-concept (Total Industrial Management) makes Ebbecke the perfect partner to outsource any type of drying process.
