Food processing demands channels resistant to acidic environments:
Material Selection:
316L stainless steel channels resist 80°C syrup corrosion, with pitting resistance ≥40 PREN in Brazil's sugarcane mills.
Cleanability:
Smooth-welded channels (Ra ≤0.8μm) prevent bacterial growth, meeting FDA 21 CFR 177.2410 standards in US refineries.
Thermal Expansion:
Channels with expansion joints accommodate 3mm/m length changes, preventing warping in India's Punjab sugar mills during evaporation cycles.
