Ice-creams, flavoured yoghurt/milk, lassi, cheese, paneer, curd… are our favourite dairy products and of course, the packed milk. Today in India milk processing distribution is carried out by multiple agencies, both from private and public sectors. Processing rooms are fitted with a long stretch of stainless steel machines, pumps, silos, unending pipelines… which are handled by just a handful of uniformed workers. While the ambience gives the feel of a hospital clean room or a pharma factory, it is interesting to know how these large silos and pipes are cleaned without dismantling or pulling them down. Mohana M reports on the various Cleaning In Place processes and industrial cleaning practices at some of the leading dairy processing units in India.
