ABSTRACT:
A method and apparatus for pasteurizing comminuted wood. A housing is substantially sealed over the hatch of a ship's cargo hold before it is opened. The hold contains comminuted wood for transport, which are typically contaminated with pathogens that it is desired to destroy. Hot water is provided to combine with the comminuted wood to form a slurry. The slurry is pumped to a pasteurization vessel where it is held for a predetermined pasteurization temperature and time. Subsequent to the predetermined pasteurization time, the slurry exits the pasteurization vessel and the water is reclaimed from the wood chips. The reclaimed water is preferentially reused to slurry more chips. The method and apparatus preferably include employing an air removal and cleaning system which maintains the environment within the cargo hold at conditions tolerable for a worker to work therein, the air removal and cleaning system purifying the air obtained therefrom before exhausting it into the atmosphere.
