Claim 0:
1. A process for producing a rubber mixture in a mixing apparatus comprising at least one mixing chamber in which rotors are disposed,
wherein plant control system process parameters, including the speed of the rotors, the suction output of a suction device, and the mixing time, are controlled by open- or closed-loop control is provided;
wherein at least one rubber is mixed in the at least one mixing chamber with at least one filler and at least one coupling agent; and
wherein the suction device removes a gas mixture present in and above the at least one mixing chamber;
wherein volatile organic compounds present in the gas mixture are detected continuously in the suction device;
wherein, in the event of exceedance of a concentration of the volatile organic compounds in the gas mixture that has been defined as a control limit, the concentration measured is employed as a control variable in the plant control system for closed-loop control of at least one of the process parameters; and,
wherein, in the event of exceedance of a concentration of the volatile organic compounds in the gas mixture that has been defined as a safety limit, the plant control system causes a safety shutdown of the mixing apparatus.
