ABSTRACT:
A method for mixing and masticating highly viscous materials in a mixing apparatus comprising a mixing chamber the wall of which is provided with heat exchange means for heating and cooling and at least one rotor, driven by a motor, wherein the energy utilized for mixing and masticating (UE) and the supplied energy (SE) are determined by recording the couple and the number of revolutions of the rotors, and the heat exchanged between the materials treated and the wall is determined by recording the temperature of the materials treated, the temperatures of the heat transfer medium on entering and leaving the heat exchange circuit and the flow rate of the heat transfer medium, and the ratio of UE to SE is adjusted to an optimal value at a minimal SE.
