Wood chip optimizer

Abstract From the Canadian patent

A wood chip conditioner that uses at least two closely spaced counter-rotating, rolls having a regular wave shaped profile formed into their surfaces having a repeating pattern of peaks and valleys that radially circumscribes the roll and which are preferably the same dimension and offset from each other so that a peak on one roll is in registry with a valley on the other roll and form a nip through which oversized wood chips traverse. The chips passing through the nip are destructured by being bent and compressed by the surfaces on the rolls which produces internal cracks along the grain of the wood without penetrating the chips. The rolls are also designed to avoid breaking or fracturing …
