Claims
- 1. A debarking apparatus comprising:
(a) a rectangular bin having two endwalls and two elongate sidewalls; (b) a plurality of substantially parallel abrader rotors placed across the bin; (c) a plurality of abrader blocks attached to the abrader rotors in a longitudinally spaced manner; and (d) wherein one sidewall or a portion of one sidewall may be displaced to release logs held within the bin.
- 2. The debarking apparatus of claim 1 wherein the abrader blocks of one abrader rotor interleave with the abrader blocks of an adjacent abrader rotor.
- 3. The debarking apparatus of claim 1 wherein the plurality of abrader rotors and abrader blocks creates a live floor.
- 4. The debarking apparatus of claim 1 further comprising stationary finger plates disposed between the abrader rotors and abrader blocks.
- 5. The debarking apparatus of claim 1 comprising at least three abrader rotors.
- 6. The debarking apparatus of claim 5 wherein the rotors may be independently rotated at different speeds and in different directions.
- 7. The debarking apparatus of claim 1 wherein each abrader block comprises a replaceable abrader tips, which may be welded or bolted to the blocks.
- 8. The debarking apparatus of claim 7 wherein the abrader blocks of a rotor are arranged in a helical pattern about a central longitudinal axis of the rotor.
- 9. The debarking apparatus of claim 8 comprising means for sliding the displaceable sidewall vertically.
- 10. The debarking apparatus of claim 8 comprising means for pivoting the displaceable sidewall outwards.
- 11. The debarking apparatus of claim 8 comprising means for sliding the displaceable sidewall vertically and means for pivoting the sidewall outwards.
- 12. The debarking apparatus of claim 1 further comprising a control system for controlling a debarking process, including dwell time and speed and direction of shaft rotation.
- 13. A method of debarking logs comprising the steps of:
(a) providing a debarking apparatus including a rectangular bin having two endwalls and two elongate sidewalls; a plurality of abrader rotors placed across a lower section of the bin parallel with the sidewalls; a plurality of abrader blocks attached to the abrader rotors, and one sidewall or a portion of one sidewall may be displaced to release logs held within the bin; (b) introducing a batch of logs into the apparatus and rotating the rotors until the logs are substantially debarked; (c) displacing the sidewall to discharge the logs laterally.
