Questions and Answers

What is the purpose of the heating and flow control system in molasses recycling schemes?

  • To remove molasses from the low-raw centrifuge
  • To decrease the processing capacity of the sugar-end
  • To increase the purity of the molasses
  • To maintain a constant ratio of massecuite to recycled molasses (correct)

    • What is the benefit of using heated molasses in conditioning cold low-raw massecuite before centrifuging?

  • It increases the processing capacity of the sugar-end
  • It limits the capacity of the sugar-end
  • It provides satisfactory massecuite conditioning and reheating (correct)
  • It reduces the temperature of the massecuite

    • What is the main disadvantage of the molasses-recycling system?

  • It consumes a large portion of the low-raw centrifugal capacity
  • It requires the removal of molasses twice in the low-raw centrifuge (correct)
  • It reduces the amount of sugar that can be crystallized from the massecuite
  • It limits the processing capacity of the sugar-end

    • What could happen if the molasses recycle is not managed properly?
