AUTOMATION OF CIP PROCESS IN DAIRY INDUSTRIES USING PROGRAMMABLE CONTROLLERS AND SCADA

Cleaning-in-Place (CIP) is a crucial part to be automated in batch process industries. In many Process industries after completion of a batch, the equipment cleaning is done by using CIP process. There are many methods used for cleaning the industrial equipments like tanks in food and pharmaceutical industries, such as 3-step, 5-step and 7-step CIP. In any industry, once the batch product is manufactured, the equipments used for manufacturing should be cleaned to have hygienic products. The tanks, pipes are cleaned with different chemical solutions, such as caustic, acids, enzymes etc. To have an economical production, sometimes the solutions are recovered and reused. This paper is primarily addicted with a scene to provide combination of the concepts and application of automation of CIP in the process industries like food, dairy, beverage and pharmaceutical verticals. Proposed work for dairy industries contains CIP defined for cleaning and sterilizing of tanks, valves, and pipes with the help of acid, lye and consequent sterilization with high energy efficiency.
