1. Describe the duty
- Identify each recipe, incoming condition and required finished format.
- List target accepted output, shift length, planned changeovers and available labour.
- Mark the upstream and downstream supply boundaries, site layout and utilities.
2. Agree on acceptance before the trial
Use representative materials and include difficult products, not only the easiest recipe. Agree on a sampling method, trial duration and acceptance thresholds with the supplier. Food-safety validation remains a separate responsibility.
- Quality
- Record the product-specific measurements: weight, texture, cut, appearance, damage or moisture condition.
- Output
- Separate incoming mass, nominal batch, mechanical cycles and accepted finished output. State the units and measurement interval.
- Losses
- Record rejects, retained material, trim, rework and cleaning losses separately.
- Time
- Measure loading, processing, discharge, stops, changeover and clean-down, not just steady running.
3. Keep a repeatable trial record
- Date, supplier, exact machine identification, tools and configuration.
- Recipe reference, material lot, input condition and quantities.
- Run time, accepted output, rejects, stoppages and sampling results.
- Settings used by the supplier, observations, photographs and unresolved questions.
Request permission before filming. Label footage with the demonstrated machine and conditions; a video is not an independent capacity or safety test.
4. Compare the complete quotation
- Separate core equipment, optional modules, tooling, conveyors, controls and guards.
- Confirm drawings, energy supply, extraction, drainage, access and integration responsibilities.
- List delivery, installation, commissioning, training, spares and service coverage.
- Agree on acceptance tests, warranties, exclusions, payment milestones and quote validity.
Use the category-specific questions
Editorial scope
This checklist is an original comparison aid, not a legal contract, operating procedure or process-validation standard. Use qualified engineering and food-safety support for site-specific decisions.
Suggest a correctionProduce preparation: distinguish an integrated trap from independent destoning
KRONEN's reviewed HEWA 3800 page describes an integrated wash-tank sand trap for loosened heavy particles, including small stones. This supports that washer feature, not a selected standalone destoner or a project removal guarantee. Washing, brush treatment and peeling remain separate duties; peeler figures do not prove no-peel washing.
For the actual crop, identify incoming soil and foreign material, the required retain-peel or peel-removal result, any separately supplied stone-removal module, water and waste handling, damage and usable yield. Agree representative trials and measured acceptance limits with the responsible project team.
