Hygienic design of processing equipment requires

  • A.Painted mild steel surfaces
  • B.Smooth, drainable, crevice-free surfaces
  • C.The heaviest possible construction
  • D.Maximum use of threaded fasteners

Crevices, dead legs and horizontal ledges harbour material that cleaning cannot reach, and that material becomes a microbiological reservoir. Drainability and accessibility matter more than the material of construction alone.
