Best Practices for Hygienic Machine Design

1. Material Selection

  • Stainless Steel: Preferred for its corrosion resistance and ease of cleaning.
  • FDA-Approved Plastics: Used in areas where metal might not be suitable, ensuring non-toxicity and durability.

2. Smooth Surface Finishes

  • Polished Surfaces: Minimize the risk of bacterial growth and make cleaning more effective.
  • Seamless Welding: Eliminates crevices where contaminants can accumulate.

3. Hygienic Design Principles

  • Avoiding Sharp Corners: Rounded edges facilitate easier cleaning and reduce contamination risks.
  • Sloped Surfaces: Ensure no liquids can pool, preventing microbial growth.

4. Certified Components

  • Conveyor Belts: Use belts certified by FDA and EU for direct food contact.
  • Seals and Gaskets: Ensure they are compliant with industry-specific standards for hygiene and safety.
  • Bearings and Fasteners: Choose rust-resistant and easy-to-clean materials.

Certified Conveyor Parts and Machinery Components

Conveyor Belts

  • Modular Plastic Belts: Designed for easy cleaning and maintenance.
  • Metal-Detectable Belts: Enhance safety by allowing detection of belt fragments in the product.


  • Stainless Steel Bearings: Resistant to corrosion and designed for easy maintenance.
  • Sealed Bearings: Prevent ingress of contaminants and ensure long-term operation.

Seals and Gaskets

  • Silicone Seals: Withstand high temperatures and frequent washdowns.
  • EPDM Gaskets: Offer excellent chemical resistance and durability.
