Abstract
A method for mixing a compound in a closed-batch mixer includes predetermining a minimum temperature of a mixer body for starting a mixing cycle; predetermining a preheating temperature for a thermal-regulation system of the mixer as a first set point; predetermining a working temperature for the system as a second set point; predetermining a thermal-hysteresis value of the mixer body; predetermining a first temperature of the mixer body for switching the system from the first to the second set point; predetermining a second temperature of the mixer body for switching the system from the second to the first set point; directly measuring mixer-body temperature using continuous, real-time measurement; comparing the mixer-body temperature to the first and second temperatures; and switching the system from the first to the second set point or from the second to the first set point, if required, as a result of the comparison.
