Drying of Powders and Bulk Materials

Drying is one of the oldest process engineering operations known to humanity. Over the course of history, humans have invented new drying methods, whether to preserve food or to improve other materials. First came air drying, then other methods such as smoking and the addition of hygroscopic substances such as salt. Today we have an impressive range of drying methods, including freeze-drying, condensation methods and vacuum drying.

Drying Options

The extraction of liquids can be achieved in a variety of way such as evaporation, addition of drying agents or other methods. Generally, a phase transition of the liquid to the gaseous state is involved.

In traditional and industrial processes, the rate and quality of chemical drying depends above all on the moisture content of the material, the temperature and the specific surface area of the material.

Drying simply to reduce the water content is a relatively simple task. At IBU-tec, we specialize in more complex drying processes in which the drying kinetics or a very high purity of the end product are key factors. We have carried out such projects with ultrapure silica, aluminum oxide and other materials for a wide range of applications including medical purposes.

Using the pulsation reactor, we are able to carry out a shock-drying process, which allows us to influence certain material properties.

If you need any assistance with projects that require a chemical drying process, please contact us. We will be very happy to advise you.
