Clean-in-place (CIP) technology offers significant advantages to manufacturing facilities. CIP provides efficient and reliable cleaning of process equipment and piping at lower cost and there by improves the product quality. The controls incorporated into CIP systems are critically important, being required to provide a variety of cycle times, temperatures, composition and concentration of cleaning solutions. The clean-in-place systems may include current recycling and regeneration technologies, in order to reduce operating costs and control the cost of waste disposal.
Clean-in-place (CIP) technology is the automatic, reproducible and reliable delivery of cleaning solutions, rinse and wash water to and through process equipment and process piping. The development of CIP technology has improved both product quality and plant hygiene. Furthermore, the ability to clean a processing system, incorporating tanks, pumps, valves, filters, heat exchange units and process piping, without the need to disassemble all or part of that system significantly reduces cleaning costs and minimizes the handling of chemicals to provide a safer environment for plant personnel. These systems may be integrated into existing processing systems, but more importantly, clean-in-place technology should be included in the design of any new process system, to be simultaneously incorporated with the design of the process flows, the controls and automation. This system which was once considered as an additional cleaning facility has now become mandatory.
The CIP Technology is applicable in any process industry like Chemical plants, Food and Beverage plants, Wineries, Distilleries, Pharmaceutical industry and the most recent Bioprocess Industry. Any industry which has a closed circuit of pipes and vessels, storage tanks and looking similar to any process plants can go for an effective CIP system. The SIP (Steam in Place) also can be followed for the sterile applications. The picture shows a CIP station with a capacity of 100Liters
The CIP system is operated from the machineâ€™s central control panel. The whole process is fully automated by computer or PLC, including features such as pause and timer functions, full or part cycle on a zoned area and the concentration of cleaning detergents in the water. CIP operating systems are designed to be flexible and can be operated daily or weekly, depending on requirements. A full CIP cleaning cycle usually takes around two hours to complete. This in turn can reduce production downtime and is much faster than manual cleaning. The main problem with manual cleaning is that parts of the machine may be difficult to access or completely inaccessible. In contrast, an automated CIP system is designed to cover 100 per cent of the machineâ€™s interior. There are also health and safety issues with manual cleaning. An automated system cuts the risks associated with handling and working with chemical detergents in confined spaces. A manual system relies completely on the skills of the cleaning crew to reach quality assurance standards. CIP systems are guaranteed to maintain a high standard of hygiene.
A fully automated CIP system is designed to clean 100 per cent of the machine interior by removing food solids and bacteria. CIP systems can be developed to meet individual product and hygiene requirements. Each system is custom designed and fitted to ensure the machine interior is sanitized from ceiling to floor. A typical CIP system features interior pipe work, nozzles and cleaning heads, which can rotate 360 degrees to spray jets of water and foam detergent. These spray jets are termed as Spray Balls. A valve station is usually fitted to the roof of the freezer or chiller. The CIP system is programmed to clean each zone within the machine in sequence. With a spiral freezer for example, we can include a drum wash, belt wash and even a sequence for sanitizing the evaporator. A full cleaning cycle may include a pre-rinse with water, followed by two chemical detergent and rinse cycles to thoroughly sanitize the system.
