Mixing

Mixing is a basic mechanical process and is understood as a combination of different starting materials under energy input to form a homogeneous or heterogeneous mixture.  There is a huge number of substances to be mixed which, due to their aggregate state (solid, liquid or gaseous), differ in their compositions, as well as in their chemical properties. Density and viscosity are also of great importance when mixing, as they influence, amongst other things, the amount of energy that must be expended. 

Our latest dosing station offers considerable rationalisation possibilities for liquid raw material components.

The basic process of mixing takes place in homogenisation mixers. We advise on every aspect of used homogenisation mixers and process plants and also have these items for sale.

Mixing is not only a part of many industrial process steps, but is also to be found in numerous everyday areas, such as the kitchen (mixers), the car (carburetor) or the building trade (concrete mixers).

In cosmetic and pharmaceutical process technology, a distinction is primarily made between liquid or highly viscous products when mixing, as well as whether the phases to be mixed easily mix or even repel. Depending on the basic parameters, the mixing process has to be adapted to these and can vary from relatively simple to highly complex.

Applications

Mixing processes are applied (as a sub-area) in virtually all cosmetic, pharmaceutical and chemical production processes, for example in

• Cremes
• Ointments
• Hair care products

Details

The economic efficiency of a mixing process depends on the energy expended for the mixing process. The mixing process may take place in a batch or in a continuous process. Agitation, a sub-area of mixing, typifies this, as it is possible to adapt the energy input over a wide range of applications to the end product and thus to produce a large number of products. In order to produce a mixture from substances which do not spontaneously form a homogeneous mixture, it is crucial that the mixer generates as much relative motion as possible. Ideally, the intensity and direction of the force input tend to change continuously throughout the process. The variety of production machine designs is owed to the multitude of different applications. Depending on the process, the procedure of the mixing processes can vary considerably. Thus, a coordinated interpretation of the process is a guarantee for optimum production results. We will be pleased to advise you on the subject of mixing.
