The frozen vegetable trade converges on a small set of nominal cuts, because dicing equipment is built around interchangeable knife sets and because customers inherited the same geometries from the canning industry before them.
The cuts that are actually held
| Cut | Typical use |
|---|---|
| Fine dice | Dry and wet soup bases, sauces, pate and filling systems where the particle should not dominate |
| Standard dice | The volume cut: soups, stews, ready meals, mixed vegetable blends |
| Large dice | Chunky soups, casseroles, food service sides where the piece is meant to be seen |
| Slice, plain or crinkle | Mixed vegetable packs and retail blends; crinkle raises surface area and visual bulk |
| Baton and julienne | Stir-fry blends, side vegetables, garnish |
| Whole baby carrot | Premium side vegetable and retail blends |
Fine, standard and large dice cover the overwhelming majority of industrial volume. If your requirement can be met by one of them, it will be cheaper, faster and more consistently available than a bespoke geometry, because the plant is already running it.
Why a nominal size is not a specification
Dicing a biological object produces a distribution, not a dimension. A usable clause therefore states five things: the nominal dimension, the tolerance band around it, the maximum permitted fraction outside that band, the maximum fines fraction below a stated aperture, and the method and sample mass used to verify. Sieve apertures should be quoted in millimetres or micrometres with reference to a defined test sieve series rather than as a bare mesh number.
Fines are the parameter that causes complaints
Fines and slivers are the offcuts generated at the ends of the root and at every knife change. They thaw first, they release water into a sauce, they discolour, and because they are dense they migrate to the bottom of a carton during transport. The result is that the last portion out of a bag looks and behaves differently from the first. A supplier who is willing to state a fines maximum and to verify it on a named sieve is telling you something meaningful about the line.
Practical advice
Send the supplier a physical reference sample or a photograph against a scale alongside the written clause. Words and numbers describe a cut imperfectly; a reference sample removes most of the ambiguity in one step. Where the dice will sit in a blend, specify it against the other components too – the soup mix guide explains why matching hydration behaviour across a blend matters more than matching nominal size.
