Three of the following are used to remove foreign matter. Which grades acceptable produce?

Diverging belt sizer

Destoner

Magnetic separator

Aspirator

  • A.Aspirator
  • B.Diverging belt sizer
  • C.Destoner
  • D.Magnetic separator

Answer: B

Correct answer: Diverging belt sizer

Cleaning removes what should not be there; grading sorts what should. An aspirator, a destoner and a magnet all remove foreign matter - chaff, stones and tramp metal respectively. A diverging belt sizer takes sound fruit and sorts it into size classes, which is grading, and it is normally placed after cleaning is complete.
