Abstract
Cleaning In place (CIP) is a method used for cleaning of filling machines and process equipment without disassembling them. Programmable logic controller (PLC) is used to automate this electro-mechanical process in which different detergents are used for cleaning. Solenoid valves control the movement of chemicals. In addition to this, maintained temperature is required because correct temperature of the detergent is important to dissolve the product leftovers. Moreover, turbulence is needed which can be generated by frictional forces at the confining solid walls for the removal of product remnants. This time based process is done in such a way that three tanks are used for the storage of chemicals whereas PLC is programmed with the intention that solenoid valves would manage the movement of detergents. Heater and temperature sensor is placed to maintain the required temperature. Pump is used to create a pressure while flow meter is designed and installed to measure the flow. It is important to do CIP after the end of the production in order to prevent the product from getting dry and to avoid the microbiological growth. Automation provides us optimized productivity with the quality services beyond the current quality of human labor. It is highly applicable in food industry.
