Ultrasonic machines and spray machines are the two most widely used methods for anilox cleaning in flexible packaging. Which washing system is more effective for anilox cleaning?

WHAT ARE THE COMMON POINTS?

Let’s start by discussing the common points of the two systems:

1) Both use chemistry to soften the ink present in the cells of the anilox. They can operate with non-flammable and non-toxic cleaners.

2) The liquids are heated to use temperature to effectively break down the residues in the cells.

3) Both ultrasonic machines and spray machines require the rotation of the cylinder inside the machine, but with some differences.

WHAT ARE THE DIFFERENCES BETWEEN THE TWO SYSTEMS?

1) Mechanical vs. Ultrasound

Spray machines primarily use mechanical action on two axes: the anilox rotates while a carriage with nozzles moves slowly along the axis several times. The washing cycle involves multiple steps depending on the level of contamination of the cylinder. This is followed by a rinsing cycle with pressurized water to remove the residues. previously softened.

Ultrasonic machines, on the other hand, use high-frequency sound waves to create cavitations in the cleaning solution, thereby generating a uniform mechanical cleaning action across the entire surface of the anilox rollers.

2) Convenience and machine size

If the anilox also has a shaft, the size of spray machines is generally larger because they need to accommodate the entire anilox. The systems are less bulky in the case of sleeves.

Nelle macchine a ultrasuoni invece è immersa solo la tavola dell’anilox. Gli ingranaggi rimangono esterni alla vasca pertanto la struttura è meno ampia.

Questo fattore implica anche un forte risparmio in termini di struttura della macchina.

3) Rapidità dei lavaggi

Avendo un carrello con gli ugelli che effettua diversi passaggi lungo l’asse per spruzzare il detergente, risciacquare ed asciugare, il ciclo di pulizia delle macchina a spruzzo senz’altro dura di più rispetto ad una macchina ad ultrasuoni.

Infatti, l’azione uniforme degli ultrasuoni è come quella di una “friggitrice”: lavora in contemporanea su tutte le componenti pertanto i lavaggi sono molto più rapidi.

…E negli avviamenti il fattore velocità è senz’altro fondamentale!

In conclusione, se desideri velocità ed efficacia neI lavaggi, il sistema di pulizia per gli anilox più efficace, rapido ed economicamente vantaggioso è una lava anilox ad ultrasuoni. Se vuoi saperne di più, vai alla pagina riguardante la linea Ditomsounds.
