Japanese Patent JPS5227241
Kind Code:
B2
Abstract:
Air is circulated through a body of wood chips at a rate sufficient for maintaining a uniform temperature and oxygen content throughout the body of wood chips. Fresh air is supplied at a rate sufficient for keeping the oxygen content of the circulating air at 16% by volume, at least. The temperature is maintained at 35 DEG -80 DEG C. This process results in a rapid seasoning of the natural resin, of the wood chips, making it possible to use the wood chips for pulping after 1-4 days only.
