In the forest industry debarking lines can be optimized for better quality and profitability using Photoboiler solutions. The aim of the debarking is to remove just enough bark to have a high quality clean wood product, but not more so that the loss of valuable fiber is minimized.
In practice the optimization of debarking is set up by installing two cameras on the line:The main after the debarking drum will monitor the main product and secondary camera on the bark line to monitor the composition of the removed material. The main camera’s goal is to ensure no bark is left on the wood. The secondary camera ensures that the bark flow contains as little fiber wood as possible.
Once the two cameras have been installed it is possible to optimize the balance between the cleanliness of the main wood flow and the barks stream fiber wood content. Typically the cameras are connected to the plant automation system and that is where the optimization happens in practice.
Optimization of debarking can yield substantial financial return both in terms of improved fiber quality as well as minimized fiber loss.
