Rice Polisher & Huller Sieve Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for removing bran during rice whitening and polishing through slotted perforated screens that surround the milling chamber. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.
