1. A process for continuously manufacturing formulations, the process comprising:
continuously feeding feedstocks into a process mixer (kP) in which there is a first mixing device for mixing of the feedstocks,
continuously manufacturing a formulation by mixing the feedstocks in the process mixer (kP) and transferring the formulation into a buffer tank with a second mixing device via a connection between the process mixer (kP) and the buffer tank,
ascertaining properties of the continuously manufactured formulation by means of a measurement unit, the measurement unit being assigned to the connection of process mixer and buffer tank or arranged within a corresponding conduit system,
determining a deviation of properties from a predetermined desired state in a predictive state of the overall batch of the formulation based on the properties of the continuously manufactured formulation by means of an evaluation unit,
ascertaining adjustment volumes for feedstocks that are needed in view of the deviations in the properties of the continuously manufactured formulation from the target state of the overall batch and a total volume of formulation volume to be manufactured for establishment of a target state of the total volume,
continuously manufacturing further portions of the formulation in the process mixer (kP), taking account of the adjustment volumes ascertained by adjusting the feed of feedstocks into the process mixer (kP), and
combining the manufactured portions for manufacture of the total volume.
