Tube sheets in the food industry: hygienic design considerations

Tube sheets in the food industry must meet stringent hygienic design standards. Materials should be food-grade stainless steel, with a smooth surface free of crevices to prevent microbial growth, and possess corrosion resistance and ease of cleaning to ensure safety in contact with food.

The design should optimize the structure, minimizing gaps and recesses, and utilizing rounded transitions for thorough cleaning and disinfection. Reliable sealing of connections to piping is also crucial to prevent leakage and contamination.

The manufacturing process must comply with GMP (Good Manufacturing Practice) standards, strictly controlling processing precision and surface treatment to avoid residues. Regular maintenance and inspection are necessary to ensure the hygienic reliability of the tube sheets in food production.
