Understand your milk quality and equipment hygiene by using aseptic sampling equipment and techniques to collect a sample that will not be contaminated by the sampling procedure. Install QualiTru TruStream Sanitary Ports before and after the filters and the plate cooler, and on all robots, and after the buffer tank before the milk goes into the bulk tank. Sample the sites using a peristaltic pump to collect a representative sample and locate the contamination source. Sampling ports can also be installed to diagnose possible system contamination from the parlor to the storage tank. Effective diagnostic analysis requires both effective sampling and test procedures.
