DESIGNING FOOD FACTORY DESIGNING FOOD FACTORY DOORS & WALLS DOORS & WALLS 5 SANITARY DESIGN CONSIDERATIONS 1. MATERIAL SELECTION & SURFACE FINISH Use stainless steel, high-density polyethylene (HDPE), or food-safe PVC to resist moisture and microbial growth Install reinforced panels and shatterproof doors to withstand high-traffic and heavy equipment movement Prevent bacterial growth with welded seams and rounded corners on walls and doors Utilize high-performance insulation to maintain temperature stability and prevent condensation buildup Avoid materials like untreated wood or standard drywall, which can absorb moisture and degrade over time 2. HYGIENIC SEALING & JOINT DESIGN Install fully sealed doors with minimal gaps to prevent debris and pathogen infiltration Use food-grade, antimicrobial gaskets that are easy to replace and resistant to degradation Apply anti-microbial and chemical-resistant coatings for enhanced sanitation Ensure air curtains or HEPA-filtered barriers at doorways to prevent airborne contamination Design doors with quick-release hinges and removable panels for deep cleaning 3. DURABILITY & RESISTANCE TO HARSH ENVIRONMENTS Choose impact-resistant doors (e.g., stainless steel or heavy- duty FRP) to withstand frequent use, trolley movement, and sanitation procedures. (e.g., epoxy or Walls should have protective coatings polyurethane) that resist high-pressure washing, chemical exposure, and thermal fluctuations. Install stainless-steel kick plates on doors and wall guards to protect against mechanical damage. 4. EFFECTIVE DRAINAGE & MOISTURE CONTROL Ensure properly sloped walls and hidden drainage channels to prevent water stagnation Use insulated wall panels and dehumidification systems to minimize bacterial growth Avoid step-up or recessed thresholds that can trap food particles and hinder sanitation Ensure walls and doors withstand high-pressure and steam cleaning cycles Use hygienic grommets and silicone-sealed conduit holes to prevent pest entry 5. CLEANING & MAINTENANCE ACCESSIBILITY Doors should have minimal hardware and smooth, non- porous surfaces to facilitate thorough cleaning. Walls should be constructed with large, seamless panels to reduce joints and minimize bacterial buildup. Modular wall panels or hygienic cladding should be used for easy replacement in case of damage or contamination. Doors and walls should be resistant to high-pressure washdowns and harsh cleaning chemicals used in food processing environments. Ensure wall-floor accumulation and allow easy cleaning. junctions are coved to prevent dirt OUR EXPERTISE PMG Engineering delivers end-to-end engineering design and project management services for the food manufacturing facilities globally We collaborate with stakeholders to define the quality objectives and criteria for the turnkey solution project We ensure that the quality requirements align with the project goals, stakeholder expectations, and relevant industry standards Our project management expertise contributes to the successful development and implementation of the quality assurance plan in solutions PARTNER WITH PMG TO BUILD WORLD-CLASS FOOD FACTORIES THAT MEET GLOBAL STANDARDS ABOUT PMG BUILD WORLD CLASS FOOD FACTORIES At PMG, we offer complete solutions from design to commissioning, specializing in food factory construction that meets global standards.
