| Product Contact Surfaces | Use food-contact materials suitable for the intended food, temperature, moisture, fats, and cleaning chemicals. Stainless steel 304 is commonly used; stainless steel 316 may be selected for higher chloride exposure. | Reduces contamination, corrosion, material migration, and foreign-body risks under Codex good hygiene practices. | Review material certificates, food-contact declarations, weld specifications, and chemical-resistance information. | Complete material traceability and written suitability documentation for every product-contact component. |
| Hygienic Design | Avoid food traps, dead legs, exposed threads, unsealed hollow sections, sharp internal corners, and inaccessible product-contact areas. | Supports prerequisite programs and prevents microbial growth or allergen accumulation. | Perform a documented design review, visual inspection, and cleaning-access assessment before purchase. | All product-contact zones are accessible for inspection, cleaning, sanitation, and drying. |
| Ingredient Feeding and Dosing | Provide controlled dosing for cereals, binders, nuts, seeds, inclusions, and coatings; define target weight and permitted process tolerance during commissioning. | Controls formulation accuracy, allergen segregation, nutritional declarations, and batch consistency. | Run a representative trial using the buyer’s actual recipes and record dose repeatability over multiple cycles. | Trial results meet the approved recipe tolerance and produce a documented batch record. |
| Mixing and Binding | Control mixing time, temperature, binder addition, and product residence time. Record critical operating limits in the HACCP plan where applicable. | Helps control uneven binder distribution, inadequate process control, texture defects, and potential microbial hazards. | Conduct process validation with minimum, nominal, and maximum operating settings. | Validated operating ranges, alarm limits, and corrective actions are documented and reproducible. |
| Forming, Slabbing, and Cutting | Provide adjustable thickness, width, length, and cutting speed with safe guarding around moving parts. | Supports weight control and prevents physical hazards from damaged blades, loose parts, or equipment fragments. | Check dimensions, net weight, cut accuracy, guard interlocks, and emergency-stop operation during factory acceptance testing. | Product dimensions and weights meet the approved specification; safety devices stop hazardous motion as designed. |
| Thermal Processing or Cooling | Measure and record time and temperature where heating, baking, drying, or controlled cooling is part of the process. | Provides objective evidence for validated process controls and helps manage moisture-related stability risks. | Use calibrated sensors and conduct temperature mapping or time-temperature validation under loaded conditions. | Validated critical limits, sensor calibration records, and defined deviation procedures are available. |
| Allergen Changeover | Design for tool-free or controlled dismantling where practical, with separate utensils or verified cleaning procedures for allergen-containing recipes. | Controls unintended allergen cross-contact involving ingredients such as peanuts, tree nuts, milk, soy, sesame, or wheat. | Review the allergen matrix, conduct cleaning validation, and test representative post-cleaning surfaces or product samples. | Approved changeover procedure, acceptance limits, verification records, and corrective actions are established. |
| Cleaning and Sanitation | Define wet-cleaning, dry-cleaning, or combined procedures according to the formulation and equipment design. Avoid residual water in areas not designed for wet cleaning. | Supports Codex sanitation programs and reduces biological, chemical, and allergen contamination. | Measure cleaning time, chemical concentration where used, rinse requirements, visual cleanliness, and microbiological or allergen verification. | Validated sanitation standard operating procedures and completed sanitation records are available. |
| Foreign-Body Control | Allow integration or placement of suitable sieves, magnets, metal detection, or X-ray inspection according to the hazard analysis. | Controls physical hazards from metal, stones, glass, hard plastic, damaged tools, or equipment parts. | Complete challenge tests using approved test pieces and define testing frequency, reject confirmation, and product isolation procedures. | Detection sensitivity, rejection function, alarms, and verification frequency are documented and validated for the product. |
| Utilities and Compressed Air | Specify hygienic water, air, steam, electrical, and drainage requirements. Air that contacts food or food-contact surfaces requires appropriate filtration and quality control. | Prevents contamination from utilities and supports the Codex prerequisite programs. | Review utility specifications, filtration arrangements, water quality records, air-quality testing, and drainage design. | Utility quality limits, maintenance schedules, test results, and connection diagrams are provided. |
| Calibration and Monitoring | Identify instruments used for temperature, weight, pressure, speed, moisture, and detection controls; define calibration intervals based on risk and performance history. | Ensures measurements used for critical limits and verification are reliable. | Review calibration certificates, traceability to recognized standards, out-of-tolerance procedures, and instrument identification. | All critical instruments have current calibration status and documented corrective actions for failures. |
| Traceability and Data Records | Record batch identification, recipe version, operating parameters, alarms, operator actions, cleaning status, and inspection results. | Supports Codex traceability, recall readiness, HACCP verification, and investigation of deviations. | Test data export, user permissions, time stamps, backup procedures, and record-retention settings. | Records are legible, protected from unauthorized alteration, retrievable, and linked to the finished-product lot. |
| Safety Guards and Emergency Controls | Provide fixed or interlocked guards, emergency stops, safe access points, lockout provisions, and appropriate electrical protection for the installation environment. | Protects personnel and reduces the possibility of contamination caused by unsafe intervention during operation or cleaning. | Conduct a documented risk assessment and verify guard, interlock, emergency-stop, and restart-prevention functions. | Safety functions pass commissioning tests and are supported by operating and maintenance instructions. |
| Documentation Package | Supply food-contact declarations, manuals, electrical drawings, pneumatic diagrams, spare-parts lists, cleaning instructions, risk assessment, and validation protocols. | Enables the buyer to implement prerequisite programs, HACCP controls, training, maintenance, and verification. | Use a document checklist during design qualification, factory acceptance testing, and site acceptance testing. | All required documents are supplied in the agreed language and revised to match the installed machine. |
| HACCP and Codex Alignment | Integrate the machine into the site’s hazard analysis, prerequisite programs, monitoring procedures, corrective actions, verification, and recordkeeping system. | Codex CXC 1-1969 establishes the General Principles of Food Hygiene and the HACCP system framework; the machine itself does not automatically create HACCP compliance. | Complete a site-specific hazard analysis and confirm controls during commissioning and routine production. | Signed commissioning records show that identified hazards, critical limits, monitoring, corrective actions, and verification activities are operational. |
