Air injectors (also called ‘flushing pulsators’) increase turbulence and improve cleaning – making it less likely that additional cleaning of the plant will be required.
Air injectors are usually located on the milk line. They periodically (2-3 cycles per minute) admit air, creating a large slug of wash fluids to increase mechanical scrubbing down the milk line. They are standard issue on newer installations but some older dairies with milk lines of 50mm or more may benefit from a retrofit if cleaning is less than ideal.
Tips on Getting the Best Result
Should be fitted professionally and filters checked periodically. Easy to see if working by watching action of wash fluids through face plate of receiver.
Pros and Cons
Reduce power and chemical costs and may improve milk quality.
Will reduce the temperature of the wash solutions more quickly.
Issues in Making it Happen
Should improve effectiveness of clean.
