The industrial mixing and wetting of powdery goods takes place either batchwise or continuously. In the case of continuous mixing, a distinction is made between the pipe flow and the boiler flow. In practice, there are also hybride forms of both processes.

The ability to protect food from decay is a high cultural achievement. Even more than 10,000 years ago, storing food by protecting meat or excess crops from spoiling was essential for survival. What we now call packaging was also a top priority back then.

Pressure and vacuum resistant reactors are required when vacuum drying is to be carried out. Then the wet or moist product must also be heated. This is usually done by giving the mixer a double jacket. A heat transfer medium circulates in the double jacket. This is steam, water, thermal oil or a molten salt (at particularly…

Many dietary products are available in powder form, quite a few even as powder mixtures. Powder preparation is therefore of special importance. In contrast to liquid preparations, powders have a longer shelf life.

Wherever powdery goods are processed, dusts occur. Their unpleasant property is that they can escape through the smallest of leaks. For example, from big bags, mixers, silos, pipelines or from filling/ packing plants. Dust can remain suspended in the air for a long time and be deposited everywhere.

These days, instant foods are offered as hot or cold meals. Instant food is all the better quality the more nutritional it is and the more natural it tastes. The preparation process must be simple, preferably with a “success guarantee”.

Gewürze sind im weitesten Sinne Blüten, Knospen, Früchte, Samen, Rinden, Wurzeln, Wurzelstöcke, Zwiebeln oder Teile davon, meist in getrockneter Form. Kräuter sind frische oder getrocknete Blätter, Blüten, Sprossen oder Teile davon.

A milk replacer must be easily digestible for the young animal. Its formula is therefore adapted to the age and the stage of development of the digestive organs. The mixing task is ambitious. The powdered milk derivatives must be gently homogenized so that they can be quickly dissolved in water by the user - as instant…

Powder metallurgy is a special field of material science. Fine powders of iron, steel and non-ferrous metals are pressed to form a workpiece. Some methods of powder preparation and processing are similar to the production of high-performance engineering ceramics.
