  • Patent number: 4148346
    Abstract: A method of and apparatus for removing bark from a log or cant. The cant is fed via an infeed section which eliminates limbs to a two-stage drier section in which a radial frequency generator with plate electrodes creates an electrical field in the cant to heat the moisture therein by dielectric means. In the second stage a concentrated electrical field is applied to the bark area by oval electrodes to produce a gas buildup between the cambium and the bark to cause partial separation of the bark. The drier section is followed by a three-stage debarking section, with brushes in the first stage for removing loose, large bark pieces, with crusher heads in the second stage to loosen, raise and flake the remaining bark without damaging the wood, and a final brush section for removing rough edges and create a smooth finish.
