  • Page 33 10. Drop Height: Potatoes are sensitive to bruising during the har- vesting, transporting and conveying phases of your operation. Bruising is kept to a minimum by maintaining a full flow of potatoes through each machine and minimizing all drop heights. Bruising during the conveying phase can be minimized by keeping the drop height between each piece of equipment as small as possible.
