original manufacturing equipment or can be based on standalone systems which operate on and control one of more pieces of equipment. Modern CIP systems will assist with record keeping for the purposes of traceability, including records of key parameters such as temperature, pressure, chemical concentration and cleaning time.
rinsing, a high temperate caustic or chemical wash, and various intermediate and final rinses. Washing processes use a combination of chemicals and agitation (such as turbulent flow in corrugated pipes) to remove dirt.
All of these processes are controlled by integrated controls and systems such as flow meters, conductivity transmitters and turbidity sensors. Depending on the system, the final rinse may use potable or sterilised water, or another form of sanitising rinse containing bleach or peracetic acid (PAA), although in many situations it is preferable to rely on water alone. Air may also be passed through the system to ensure it is fully dry before production recommences. CIP systems are generally classified as either single use or reuse. Single use systems discard all the liquid after use, while reuse systems store cleaning fluids for reuse in subsequent cleaning cycles. CIP systems can be integrated into the
DESIGN CONSIDERATIONS FOR CIP If CIP is to be effective, not only does the CIP system itself need to be well designed, but the production equipment should also be considered with effective CIP in mind from the outset. Equipment and machinery must be hygienically designed and easy to manage, maintain and audit.
The design process must not only ensure effective cleaning but should also be as efficient as possible in terms of water, chemical and energy use. Considerations for the equipment itself include areas such as surface roughness, clean welding and the prevention of inaccessible areas or corners where dirt and/or cleaning chemicals may build up. Reliability is also an important consideration and CIP systems must be designed to operate for as long as the working lifetime of the equipment involved. It is also important to consider how user-friendly the control systems for the CIP are. For example, are they part of the overall control interface or a separate system?
CIP SYSTEMS FROM HRS
HRS offers both integrated and standalone CIP systems. Integrated CIP is included in many of our complete systems, such as HRS pasteurisers and sterilisers, as well as our Asepticblock Series (where the AF aseptic filler & pasteuriser/steriliser are combined in one skid) and stand-alone aseptic fillers, for example. Our standalone CIP systems are fully skid mounted and have modular designs for quick and easy site installation. The single-tank (ST) system is designed for simple cleaning applications where recovery of the cleaning fluid is not required, while multi-tank (MT) systems are suitable for more complex situations. For small, portable applications, the tank can be heated to 85°C using electric heating elements, but steam heating using an HRS K Series multitube heat exchanger is also available. Units start at 500 litre capacity, and single tank systems are available up to 2,500 litres. Larger systems can be provided using multiple tanks, and centrifugal sanitary pumps are fitted as standard. Systems are fully automated using Programmable Logic Controller (PLC) systems and Human-Machine Interfaces (HMI), which can be standalone or integrated into the factory’s main control system.
