How to clean Steel with an Ultrasonic Cleaner- Case Study

Process for cleaning Steel:

Screw mixing element - The part was placed into the basket and set for a cycle time of 10 minutes, then inspected. The screw showed good results after 10 minutes but needed more time, the part was cleaned for a further 10 minutes, after a total time of 20 minutes the screw appears visually clean. The Screw mixing element was then rinsed for 3 minutes to ensure that no left on H14 could stain or damage the part. The part was then dried in the Versa hot air dryer for 5 minutes at 65°C.

Leistritz breaker plate - Again the plate was cleaned for 10 minutes then inspected, the body of the plate had slightly brightened up and some staining removed but the polymer deposit in the holes still remain. The Plate had a total time of 40 minutes, the H14 combined with the Sonics does loosen the polymer but not enough to completely remove it.

Process for removing food debris from Steel:

The tank was diluted with an initial 5% concentration of Decoclean 440, degassed and allowed to reach temperature. The strainer was placed in the basket then submerged in the tank and set for a cycle time of 10 minutes, the part was inspected and the contamination had started to soften. The concentration was increased to 10% and the strainer placed back in the tank for further cleaning. The strainer had a total cleaning time of 60 minutes in the ultrasonic wash tank; the part was then rinsed in DI water for 3 minutes followed by 10 minutes in the hot air dryer.
