Alfa Laval Controlled Rotating Retractors

In spray-drying applications, including powder production, within hygienic processing industries, incomplete cleaning of hard-to-reach surfaces can lead to contamination risks, product loss and costly downtime. To address these challenges, Alfa Laval has launched the Controlled Rotating Retractors, designed to effectively remove residues and contaminants from ducts, pipes, tank and enclosed areas.

Expanding Alfa Laval’s tank cleaning portfolio of retractable cleaning device, these CIP cleaning devices are suitable for manufacturers across the dairy, food, beverage, pharmaceutical and biotech industries.

Designed to optimise cleaning performance in hygienic processing lines, the devices are claimed to deliver up to twice the cleaning efficiency of traditional static spray ball systems, effectively reaching shadow zones while reducing water and cleaning media consumption.

The devices are designed to reduce water and cleaning media usage by up to 55% compared to static spray balls. Their extended jet reach allows each unit to cover a larger surface area, minimising the number of devices required.

Integrated with the Alfa Laval ThinkTop V70 sensing and control unit, the cleaning devices can provide real-time monitoring and performance validation.

During production, the rotating cleaning retractors remain sealed and flush with the vessel wall, preventing contact with the product area. During cleaning, the cleaner head extends to provide full coverage of product-contact surfaces. Once the cleaning cycle is complete, the cleaner head retracts, leaving the duct, pipe, tank or enclosed area ready for immediate production.

The devices support good manufacturing and hygienic practices and comply with FDA, EU and China regulations.
