Industrial cleaning is the process of achieving to remove unwanted or residual material and maintaining that state. This can be done by:
- Mechanically
- Scrapers, to remove dirt
- Brushes
- Filters
- Gases
- Vacuum cleaners
- Airblasters
- Chemically, by using detergents
- Liquids
- Rinsing and flushing
- Spraying
- Solids
- Ice
- Balls
- Vibrations
- Acoustic, using sound waves
- Vibrations using shakers
- Thermal, like steam or burners
- Passive
- Non-stick linings
- Anti bacterial materials
Clean-in-Place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembling the system. Up to the 1950's, closed systems were disassembled and cleaned manually. Industries that rely heavily on CIP are those requiring high levels of hygiene, and include: dairy, beverage, brewing, processed foods, pharmaceutical, and cosmetics.
The benefit to industries that use CIP is that the cleaning is faster, less labor intensive and more repeatable, and poses less of a chemical exposure risk to people. CIP started as a manual practice involving a balance tank, centrifugal pump, and connection to the system being cleaned. Since the 1950's, CIP has evolved to include fully automated systems with programmable PLC's, multiple balance tanks, sensors, valves, heat exchangers, data acquisition and specially designed spray nozzle systems. Simple, manually operated CIP systems can still be found in use today.
Depending on soil load and process geometry, the CIP design principle is one of the following:
- Deliver highly turbulent, high flow-rate solution to effect good cleaning (applies to pipe circuits and some filled equipment).
- Deliver solution as a low-energy spray to fully wet the surface (applies to lightly soiled vessels where a static spray ball may be used).
- Deliver a high energy impinging spray (applies to highly soiled or large diameter vessels where a dynamic spray device may be used).
