Homogenising
Homogenising describes mixing liquids which are soluble in each other to balance differences of concentration and temperature. The liquids which are to be mixed may vary in concentration, colour or temperature.


Heat exchange
Heat exchange describes to intensify the heat exchange in stirring vessels especially with viscous liquids. Transfer of liquid to and away from the heat exchanger (e.g. heating jacket) by means of suitable flows.
Gas injection
Gas injection describes the purpose of treating a liquid with gas is to increase the phase boundary between liquid and gas that can, for example, shorten chemical reaction times. The stirring rotor needs to divide the gas flow into small bubbles and distribute them evenly in the liquid.


Dispersing
Dispersing describes the mixture of two compounds which are not or hardly soluble in each other, e.g. to intensify the exchange of components. Dispersions (heterogeneous mixture) are instable and segregate without energy supply.
Suspending
Suspending distributes or disperses solid particles homogeneously throughout the liquid. The stirrer shall prevent sedimentation of the solid particles.
