Which statement about break rolls is FALSE?

  • A.They run at a differential of two and a half to four to one
  • B.They open the kernel and scrape endosperm from the bran
  • C.They are smooth and run at equal speed
  • D.They are fluted

Answer: C

Correct answer: They are smooth and run at equal speed

This is the false statement, and it describes the reduction rolls instead. Break rolls are fluted and run at a differential of two and a half to four to one, because they need shear to split the kernel and scrape endosperm from the bran. Reduction rolls are smooth and run at about 1.25 to 1, grinding clean semolina by compression.
