CIP cleaning system is a process that cleans internal product contact surfaces such as process piping, containers, and equipment. Typical food and beverage applications that use automatic CIP system cleaning include product transfer lines, processing tanks, homogenizers, mixers, mixers and fillers. In contrast, improper cleaning (COP) is a method that must be removed from the process when the part can not be cleaned in the field. Typical process kit washers and case gaskets that are cleaned in the component cleaners include hoses, fixtures, fittings, scale buckets, and other disassembled process components.

Chris Kressner, lead project engineer for food and beverages, explains: "There are many considerations in designing a CIP cleaning system, but first we need to understand the content of the cleaning so that TACT can be properly applied to the system design Liquid soluble products are, of course, easier to clean, but even liquids are different, and both tomato juice and orange juice contain solids that are harder to clean than sports drinks, pointing out that when focusing on dairy product lines, keep in mind that bacteria The possibility of growth, while carbonated beverages have a lower pH and higher acidity, thereby reducing the chance of contamination.

When designing a CIP cleaning system, the designer needs to look at the line size, the distance from the process to the location of the CIP system, the tank or equipment size, and the spray equipment to determine the appropriate pump size. CIP suggests a minimum line speed of at least 5 feet per second. This flow creates enough turbulence to clear spurs in a line to avoid dead legs. In addition to the line flow rate, other factors should be considered to avoid dead branches such as shoot orientation, soil level and process conditions.

Single-pot, double-pot, multi-pot and multi-loop designs are optional when setting up a CIP cleaning system. Some systems may require multiple tanks to avoid allergen cross-contamination or to improve sustainability efforts by capturing the circulating final wash water. Other processes can increase productivity through multi-loop systems, enabling customers to clean multiple processes and products simultaneously. Determine the correct investment CIP system also depends largely on the budget pressure. More design means more upfront capital costs, but also increased production capacity.
