Claim 10:
11. A process for manufacturing formulations, comprising;
feeding defined amounts of feedstocks into a process mixer in which there is a mixing device for dispersion and mixing of feedstocks;
manufacturing a part-batch of a formulation by mixing the feedstocks in the process mixer;
transferring the part-batch into a buffer tank with mixing device via a connection between process mixer and buffer tank;
ascertaining properties of the part-batch before, during or after transfer into the buffer tank by means of a measurement unit configured to ascertain properties of the part-batch;
determining a deviation of properties of the part-batch from the properties of a predefined target state of an overall batch by means of an evaluation unit configured to determine a deviation of properties of part-batches manufactured in the process mixer from the properties of the predefined target state of the overall batch;
ascertaining, by means of a unit which is in communication with the evaluation unit and configured to take account of the deviations in the properties of the manufactured part-batch from the properties of the predefined target state of the overall batch and the number and size of further part-batches in order to adjust the amounts of feedstocks fed in in the manufacture of further part-batches, the correction volumes for feedstocks that are needed in view of the deviations in the properties of the manufactured part-batch from the target state of the overall batch and the number and size of further part-batches for establishment of the target state of the overall batch;
manufacturing at least one further part-batch in the process mixer, taking account of the correction volumes ascertained in the manufacture of at least one of the further part-batches by adjustment, by means of the unit which is further configured to adjust the feed of feedstocks into the process mixer, of the feeding of feedstocks into the process mixer;
transferring the at least one further part-batch into the buffer tank; and
combining the at least one further part-batch with the first part-batch to manufacture the overall batch.
