Showering, not bathing: farewell to the immersion washer

High operational dependability and an optimised cleaning result were the paramount considerations in designing the Diajet pack washer, which works on an entirely new transit principle – diagonal transport of the crates.
Krones has adopted an entirely new approach in designing this crate washer, abandoning completely the principle of an immersion-bath construction. Testing revealed that immersion washing does not in itself achieve any significant cleaning effect. All it does is soften up dirt. Since it is normally the bath flow patterns that are used to move the crates forward, there is no relative speed between the liquid and the crates, and thus no mechanical cleaning effect.
Utilising the principle of "showering´s better than bathing", Krones has replaced the immersion bath by flush-off showering, thus combining the soaking effect with a mechanical cleaning effect.
The second major change compared to previous crate cleaning processes relates to how the crates are transported. In conventional pack washers, the rectangular crates are passed through the machine directly behind each other. This means, however, that when being sprayed from spray jets two sides of each crate are in the spray shadow of the preceding and following crates. In the Diajet, the crates are conveyed diagonally, corner to corner, so that the crate is dependably cleaned from all sides. A high-quality cleaning result and more effective washing are guaranteed.
Additional spray jets and open access from below, moreover, ensure optimum cleaning of the crate´s insides and dividers.
