    The results of a new study show that using dry additives, rather than liquids in feed, reduces the occurrence of caking and lumping in the mixer and can help prevent cross contamination.

    Cross-contamination in the mixing process results from the unintentional carry-over of a substance or ingredient from one batch to the next, produced on the same line. When changing batches, product from the batch that is currently being discharged will remain inside the equipment and be ‘carried over’ into the next batch.
