3.2. Mixing and Dispersing

To assess the quality of the condensation–emulsification, a standard shear-based system was applied as well. A Polytron 10-35 GT lab rotor-stator homogenizer from Kinematica, Switzerland, was used for dispersing the PCM phase into the continuous phase. The outer diameter of the rotor rim is 26 mm, and the inner diameter of the outer stator rim is 26.5 mm. The shear rate was varied, and a setting of γ̇ = 50 000 1/s (9200 rpm) and a dispersing time of 5 or 20 min were applied.
