Professional contract drying for individual requirements
The industrial drying of granulates and powders is an important area of process engineering and also plays an important role in Ebbecke’s range of services.
Each product has different requirements with regard to surface moisture, capillary moisture or crystal moisture.
In order to achieve a defined degree of drying and to protect sensitive products, we use different drying systems and processes. This is because not every dryer system is suitable for every product to be dried. Our customers can choose from fluidized-bed dryers, drying ovens, belt dryers and vacuum dryers.
The focus here is on vacuum drying and spray drying as an important step before the further processing of powders and granulates, e.g. for the chemical industry, food and animal feed or cosmetics. These processes are particularly suitable when sensitive products such as vitamins, hormones, proteins and essential oils need to be processed. We adapt to your individual requirements and also develop customized drying processes if required.
How does spray drying work?
In spray drying, the surface area of a liquid base material is increased by converting it into droplets, which enables faster drying. A nozzle is used to introduce the bulk material to be dried into a stream of hot air, which dries it to a fine powder in a fraction of a second. The powder, which consists of hollow spheres, also has a relatively uniform particle size, which facilitates further processing or filling. Conversely, the particles obtained can be quickly dissolved in liquids thanks to their large specific surface area.
Advantages of vacuum drying
For vacuum drying, A. Ebbecke Verfahrenstechnik AG customers have access to a highly efficient vacuum drying tunnel developed in-house. This gentle process is particularly suitable for temperature-sensitive goods such as foodstuffs, animal feed, pharmaceuticals, etc. As an economical solution, Ebbecke offers you an innovative vacuum drying system with which even large product quantities can be dried quickly and reliably. And with considerable potential for cost savings!
Further drying processes for optimum results
- Innovative infrared and microwave dryers for drying food and pharmaceuticals
- High-quality drying process to preserve the aroma, natural color, vitamin content and nutritional value of the product
- Consideration of temperature sensitivity and resistance to UV radiation
- Matching the drying process to the surface and capillary structure of the product
Precise and reliable determination of residual moisture
To precisely determine the moisture content and ensure low residual moisture, the engineers at A. Ebbecke Verfahrenstechnik AG use various measuring methods such as coulometric Karl Fischer titration and related methods. In addition, moisture analyzers from Sartorius and the software-based FMX HydroTracer system are used. Equipped in this way, we can achieve target moisture levels of up to 0.02% on our state-of-the-art systems. And that’s not all: thanks to our many years of experience and expertise, we can also ensure that the dried product is then reliably protected against moisture reabsorption by the air. Ebbecke Verfahrenstechnik does this by using plastic or aluminum inliners or nitrogen blanketing. Further drying of the product in a desiccator is also possible.
