Bleaching


  • DoublePass bleaching process improves yield and minimizes bleaching clay consumption
  • Bleaching clay performance is maximized by mixing it with oil in an atmospheric slurry tank prior to the bleacher
  • Water-washing eliminated when pretreating with special sorbents to remove residual gums and soap from single-stage enhanced degumming or neutralizing processes
  • Filter pre-coating extends filter cycle times, improves filter cake release and minimizes filter maintenance


  • Slurry tanks for mixing oil with bleaching clay and special sorbents
  • Operating conditions can be optimized for each step of the process
  • Choice of mechanical or steam-agitated bleacher
  • Screw feeders for continuous sorbent addition
  • Pre-coat system for filters
  • Efficient automated filter operation
