As well as its famous Brimi mozzarella, the milk processor also produces a range of additional cream cheese products, fresh milk, cream, butter and drinking yoghurt. The manufacture of all these products is subject to strict regulations imposed by the Ministry of Health. All processes have to be seamlessly documented and traceable. One requirement is that any faulty batch has to be detected and reported to the market within just four hours. Quality is checked by over 70,000 microbiological and around 260,000 chemical analyses a year, and the results have to be stored for a minimum of two years. As this placed a heavy burden on the existing automation system, Brimi took the decision to modernize its process control technology using a Simatic PCS 7 V8.2 control system from Siemens.
