Inventors: JENS OLOV RYHMAN NILS ANTON VOGT Title: METHOD OF PROCESSING WOOD CHIPS. 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 main- tained at 35 - 80°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.
