Technical notes for food processors evaluating leaf rolling, stuffed cabbage production, machine vision and robotic automation.
Most published material on vegetable processing automation is written to sell a machine. These notes are written to help someone decide whether a machine is worth buying at all — including the cases where it is not. A line running one short season a year, or handling product too variable to feed consistently, may be better served by the labour it already has.
Each article stays with one decision. What separates a fixed-feed cutter from a vision-guided one, and which is right for a given product mix. How machine vision behaves when fruit arrives unaligned, at inconsistent sizes, or with stems that are not where the model expects. What manual and automatic stem removal actually cost once yield loss, rework and seasonal labour availability are counted rather than assumed.
The figures used are ones DOKTEK can stand behind: measurements from its own machine, or numbers a named source publishes about theirs. Where a number is not confirmed, it is left out instead of estimated — a catalogue capacity that does not survive contact with a real product line is worse than no figure at all.
The leaf-rolling guides distinguish the dosing and fold stations already running on DOKTEK's grape-leaf pilot line from full rolling, which remains in engineering. Cabbage is a separate, unvalidated application; its guides explain the leaf, filling and line information needed before a trial can be scoped.
