Bruising costs the potato industry dearly every year, so effective strategies to maintain potato quality are very important.
Achieving the highest quality in all types of harvesting conditions can be difficult, but mist spraying has been shown to reduce bruising during the harvesting operation, particularly in dry conditions when dolmen rollers tend to cause potatoes to bounce.
The fine mist spray from the nozzles dampens both the potatoes and the rollers in the harvester.
This lubricates the passage of the potatoes over the top of the rollers and helps to prevent them being pinched and damaged.
Even when lifting conditions are relatively easy, other factors such as dry matter, handling temperature and nutrient levels can influence bruising susceptibility, so a Harvester Mister should be standard equipment fitted to all harvesters in all conditions.
