  Impurity Removal Upgrade at an Indian Spice Processing Plant

  Background: A factory in India faced export order rejections due to pepper powder contaminated with straw debris (impurity rate ≥8%).

  Solution: Implemented a multi-layer ultrasonic vibrating sifter (316L stainless steel, 60-120 mesh screens) combined with an optical sorting machine.

  Results:
  Impurity residue rate reduced to <0.5%;
  Color consistency of pepper powder improved by 90%;
  Compliance achieved with EU Regulation EC No 1881/2006 on food contaminants.
