As for pharmaceutical and food industries, the sanitation and sterility of finished products is the main requirements throughout whole process. In order to achieve this, the inner surface of processing equipment should be totally clean so that it’s easy to clean and the material will not remain in it. Otherwise, the tiny holes in the equipment can be the source of containment.
NJR has advanced electropolishing and mechanical polishing machines to polish the surface of stainless steel to make it smoother with decreased adhesion force and increased corrosion resistance. After professional polishing process, the roughness of inner surface of stainless steel vessels and tanks, Ra, can less than 0.28μm, which satisfies the standard of GMP and FDA.
