A method for optimizing the debarking result of logs debarked in a debarking drum, especially logs of mutually approximately the same size and of the same wood species, in such a way that wood losses remain as small as possible at the same time as the control values of the debarking drum are selected to be such that the debarking degree of the logs debarked in the debarking drum is of the desired order. The amount of bark remaining on the logs in the log flow discharged from the debarking drum and the amount of damaged logs in the said log flow are measured. At the same time as the amount of bark remaining on the logs is maintained at a desired level, the amount of damaged logs is kept as low as possible in such a way that the filling degree of the debarking drum is lowered whenever the amount of damaged logs is observed to increase.
A method for optimizing the debarking of logs fed to a rotating debarking drum, such that wood losses remain small while control values of the debarking drum are selected such that the amount of bark remaining on the logs including damaged logs debarked in the debarking drum is maintained at a target value, wherein the improvement comprises that the amount of bark remaining on the logs in the log flow discharged from the debarking drum and the amount of damaged logs in the said log flow are measured, and that at the same time as the amount of bark remaining on the logs is maintained at said target value, the amount of damaged logs is kept low, in such a way that the filling degree of logs fed to the debarking drum is reduced in response to a measured increase in the amount of damaged logs.
A method for optimising the debarking of logs fed to a debarking device having a rotating drum and a fill capacity, comprising:
