| Supplier reliability and project delivery | 20% | Relevant experience with layered cakes, depositing, cooling, enrobing, and packaging integration; project schedule; installation and commissioning capability. | Request references for comparable products and line layouts, a project schedule with defined milestones, a responsibility matrix, and documented commissioning procedures. Check whether the proposed scope clearly assigns responsibility for interfaces between machines. |
| After-sales service and spare parts | 10% | Availability of technical support, maintenance documentation, operator training, and critical spare parts. | Confirm support hours, escalation contacts, spare-parts lead times, warranty exclusions, and training hours in writing. Set response and resolution targets in the contract according to the plant’s location and production schedule. |
| Total cost of ownership (TCO) | 25% | Purchase price plus installation, utilities, labor, maintenance, consumables, spare parts, sanitation, and expected downtime costs. | Compare quotations on the same scope and operating assumptions. Use the same service life, operating hours, product mix, energy prices, labor rates, and financing assumptions for each proposal. Identify exclusions, optional equipment, and recurring costs. |
| Guaranteed line performance | 15% | Rated output, product dimensions, acceptable weight variation, changeover time, and performance across the agreed product and package formats. | Require a written guarantee for saleable output at the agreed product specification—not just individual machine speed. Define the test duration, product recipe, packaging format, yield measurement, and acceptance-test conditions before ordering. |
| Yield, rejects, and overall equipment effectiveness | 10% | Start-up waste, rejects, unplanned stops, and the method used to calculate availability, performance, and quality. | Agree on definitions and measurement points. Review a representative factory acceptance or site acceptance test report where available. Treat any target as project-specific and verify it using the planned product, crew, and operating conditions. |
| Food safety and hygienic design | 10% | Cleanability, product-contact materials, allergen changeover procedures, guarding, and suitability for the plant’s food-safety plan. | Review equipment drawings, material specifications, cleaning instructions, and access for inspection. Confirm applicable local regulations and site requirements with the plant’s food-safety team; do not assume a certification alone guarantees suitability. |
| Controls, integration, and maintainability | 10% | Controls compatibility, alarm history, data access, line synchronization, operator access, and maintenance access. | Request the control-system architecture, interface list, electrical documentation, backup and restore procedure, and training plan. Verify that alarms and production data can be accessed by the plant’s authorized staff. |
| Suggested TCO calculation | — | TCO over the evaluation period = equipment purchase + engineering and installation + commissioning and training + energy and utilities + labor + maintenance and spare parts + consumables + sanitation and changeover costs + downtime and lost-production costs − residual value. |
