Washing Mechanism Selector
Air bubble, vortex and brush washers are not interchangeable. Each one delivers energy to the product surface differently, and that single difference decides which crops it suits. Answer four questions and see which mechanism your product argues for — and what choosing it costs you elsewhere.
1. How does your product respond to mechanical contact?
2. What arrives on the product from the field?
3. Do stones, sand or grit come in with the crop?
4. Will the same line ever handle leafy vegetable batches?
Answer all four questions first.
Mechanism your answers argue for
What this choice costs you
| Mechanism | How it works | Suits | Bruising risk |
|---|---|---|---|
| Air bubble | Blowers inject air through a perforated manifold below the water line; the rising bubble column agitates product held in suspension | Delicate and irregular crops, and lines that also run leafy batches | Low |
| Vortex | Pumped water enters tangentially and creates a rotating flow; heavier soil, sand and sediment drop out at the base | Mixed loads, and any line with a grit problem | Medium |
| Brush roller | Counter-rotating brush rollers scrub the surface while high-pressure nozzles rinse released soil away | Firm crops with baked-on field soil | Higher |
Tell us your crops and your soil load, and an application engineer will confirm the mechanism against your own product before anything is frozen.
Get a Line ProposalScores are a weighting of the four answers against the published mechanism matrix, not a laboratory measurement. Tuber crops and true roots behave differently under the brush, so confirm your own varieties with an engineer before the specification is frozen.
