Non-food Grade Product Pipe Specifications
Non-food grade product are found early in the manufacturing process; the exact point at which a product changes from non-food to food grade is to some extent arbitrary.
This specification also covers products that will never enter the sugar process stream; such as lubricating oils, bearing cooling water and the like.
