Method and mixing plant for the batch-based production of a flowable coating material

A mixing system (1) for the batch-based manufacture of a flowable coating material from a plurality of components, comprising:

• a process mixing container (3), which is configured in order to receive components for a batch, essentially in a quantity respectively predetermined for the batch, and in order to mix the components in the process mixing container (3) in order to form a mixture having a preliminary composition;
• a reception container (5), the reception container (5) being that container from which the flowable coating material is filled following completion of the production of the coating material, and an outlet for removing the flowable material after completion thereof;
• a fluid line (7), which is fluidically connected to the process mixing container (3) and the reception container (5) in order to transfer the mixture having a preliminary composition from the process mixing container (3) into the reception container (5);
• a measuring device (23), which is assigned to the fluid line (7) and is configured in order to ascertain an actual state of the mixture having a preliminary composition during the transfer into the reception container;
• an evaluation unit (25a), which is in communication with the measuring device (23) and is configured in order to determine a deviation of the actual state of the mixture having a preliminary composition from a predefined setpoint state, and in order to ascertain an adjustment quantity for the components, which is required in order to reach the setpoint state;
• and
• a dosing device (12), which is configured in order to top up components into the mixture having a preliminary composition as a function of the required adjustment quantity, while the mixture having a preliminary composition is already being transferred from the process mixing container (3) into the reception container (5).
