发明名称 Processing whole trees
摘要 A system of substantially whole tree utilization wherein the trees are felled and subsequently slashed with the branches and top section intact to form discrete tree sections including a top section and branched bole sections, and these sections are fed into a conventional drum debarker to preferably dry and de-bark and de-branch the sections, thereby to provide branched and de-barked wood for further processing and separating bark, branches and needles. The bark and branches may be separated from each other and from the needles. The needles may be processed separately to produce chemical compounds for pharmaceutical purposes or any other use. The system of the present invention permits more economic harvesting of wood an increases the utilization of the tree by permitting utilization of not only the bole section, but also the normally unmerchandizable top and branches together with the needles.
