| 1 | Filling Accuracy and Repeatability | Target filling accuracy of approximately ±1% to ±2%, depending on product viscosity and filling volume. | Review test reports using the actual puree, pouch size, and target fill volume. | 18% | Accurate dosing reduces product giveaway, underfilled packs, and customer complaints. |
| 2 | Production Speed | Confirm the rated output in pouches per minute at the required pouch format and filling volume; do not rely only on the maximum catalog speed. | Conduct a witnessed factory acceptance test under representative production conditions. | 14% | Actual throughput is affected by product properties, pouch dimensions, sealing time, and operator intervention. |
| 3 | Pouch and Film Compatibility | Support the required premade pouch or roll-film structure, pouch width, length, spout arrangement, and laminate thickness. | Check machine drawings, sealing specifications, and sample-pouch trial results. | 12% | Compatibility directly influences sealing quality, leakage rates, waste, and future packaging flexibility. |
| 4 | Hygienic and Sanitary Design | Product-contact parts should use suitable food-grade stainless steel, have smooth surfaces, and minimize dead zones and exposed threads. | Inspect materials, weld quality, drainability, access points, and cleaning procedures. | 12% | Puree is a food product and may contain sugars, fibers, or acids that increase cleaning and contamination risks. |
| 5 | Sealing Performance | Stable heat-sealing temperature, pressure, and dwell time with no visible contamination, wrinkles, channels, or leakage. | Perform seal-integrity, burst, visual, and leakage tests using production packaging materials. | 10% | A reliable seal protects the puree from leakage, oxidation, and microbial ingress. |
| 6 | Changeover and Adjustability | Tool-less or low-tool adjustments for filling volume, pouch size, sealing parameters, and product changeover. | Time a complete changeover and verify the first acceptable production run. | 10% | Fast, repeatable changeovers improve availability when multiple puree recipes or pouch sizes are produced. |
| 7 | Cleaning and Product Recovery | Provide accessible filling paths, removable product-contact components, suitable drainage, and documented cleaning instructions. | Review cleaning time, disassembly steps, rinse access, and product-loss measurements. | 8% | Efficient cleaning supports food safety, reduces downtime, and limits puree waste between batches. |
| 8 | Controls, Monitoring, and Safety | PLC-based control, recipe storage, temperature monitoring, fault alarms, emergency stops, and protection for moving or heated parts. | Inspect the control architecture and test alarms, interlocks, sensors, and data-recording functions. | 6% | Clear controls improve process consistency, operator safety, troubleshooting, and production traceability. |
| 9 | Documentation and Compliance Support | Provide manuals, electrical diagrams, spare-parts lists, risk information, material certificates, and applicable conformity documents. | Verify document completeness and confirm that certificates apply to the proposed machine configuration. | 5% | Complete documentation simplifies installation, validation, maintenance, audits, and international shipment. |
| 10 | After-Sales Service and Spare Parts | Assess remote support, commissioning assistance, training, spare-parts availability, response procedures, and warranty terms. | Request service-level details, spare-parts lead times, training plans, and references for comparable applications. | 5% | Responsive support helps reduce downtime and protects the long-term operating value of the filling line. |
