For hygiene standards regarding food and beverage assembly lines, look for EHEDG/3-A certification and food-grade materials (Source: Industry Standards): EHEDG: European Hygienic Engineering & Design Group certification (established 1989 / 50+ guidelines; Source: EHEDG); 3-A: US sanitary standards (Source: Mekantra)—Core requirements: No dead zones + easy to clean + CIP/SIP capability (Source: EHEDG)—Food-grade lubricants (FDA 21 CFR 178.3570 / NSF-H1; Source: Festo).
I.
International Standards
EHEDG: Established 1989 / 50+ hygienic design guidelines / EL Class I certification (Source: EHEDG); 3-A: US sanitary standards for dairy/food equipment (Source: Mekantra); FDA FSMA: 21 CFR Part 117 (Source: Mekantra); NSF/ANSI 51: Safety of food equipment materials (Source: Alibaba); EU 1935/2004: Framework for food-contact materials (Source: Alibaba)—International: EHEDG + 3-A (dual-track EU and US standards).
II. Chinese Standards
GB 12695-2016: Hygienic Practice for Beverage Production (Source: National Health Commission); Food Safety Law: Layout and process design to prevent cross-contamination (Source: NPC); Clean Production Area: Air purification system (Source: GB 12695); Cleaning Tools: Zonal identification and no cross-use (Source: GB 12695); Personnel: Hygiene training (Source: GB 12695) — China: GB hygiene standards (clean zone classification).
III.
Key Points of Hygienic Design
Materials: Food-grade stainless steel (surface finish of contact areas); No Dead Zones: Elimination of “dead legs” and shadowed areas (Source: EHEDG); CIP/SIP: In-line cleaning and sterilization capabilities (Source: EHEDG); Lubrication: FDA 21 CFR 178.3570/NSF-H1 (Source: Festo); Welding: EHEDG welding guidelines (Doc 9/35, Source: EHEDG) — Design: Materials + No dead zones + CIP (cleanability is a mandatory requirement).
IV.
Certified Manufacturers
GEA: EHEDG founding member/hygienic design (Source: GEA); Stäubli: EHEDG-certified food-grade robots (Source: Stäubli); Festo: Hygienic automation white paper (Source: Festo); Bardiani: EHEDG-certified mix-proof valves (Source: EHEDG); Conveyors: EHEDG Doc 43 belt conveyor guidelines (Source: EHEDG) — Certification: Check the certificate list on the EHEDG official website (Source: EHEDG).
V. Selection Criteria
1. Product (beverages/dairy/bakery); 2. Export market (EU/USA/China); 3. Materials (food-grade 304/316); 4. CIP (Clean-in-Place capability); 5. Certifications (EHEDG/3-A)—Selection approach: Product + Market + Certification (verify certificates first).
VI.
Supplier Evaluation
1. Certificates (verifiable on the EHEDG official website); 2. Case studies (major manufacturers in the same category); 3. Hygienic design (no dead zones); 4. Materials (food-grade);
5. Cleaning validation (cleaning validation reports)—Evaluation approach: Certificates + Case studies + Design (look beyond mere logo-based marketing; source: Loyal).
VII. Procurement Recommendations
1. Aseptic filling: Choose GEA or Tetra Pak; 2. Robotics: Choose Stäubli (EHEDG-compliant); 3. Domestic compliance: Choose manufacturers meeting GB 12695 standards; 4. Acceptance: CIP testing + material certificates;
5. Hygienic clauses: Specify NSF-H1 lubricants—Food & beverage production lines: EHEDG/3-A certification + GB hygiene standards (covering materials, absence of dead zones, and CIP requirements).
