Abstract

The invention concerns a procedure for the debarking of logs, in which procedure the logs are treated with enzymes to weaken the bonds between bark and wood; an apparatus for the debarking of logs, comprising a conveyor (1) for conveying the logs to a debarker (2), in conjunction with the conveyor a piping system (3) with nozzles (4) for spraying the logs with an enzyme solution, a device (5) for separating the enzyme solution from the logs and conducting it back into the piping system (3), and a feed device (9) for supplying enzyme solution into the circulation system.
