| titleOfInvention | PROCESS FOR THE PRESERVATION OF CHIPS FROM FIBER WOOD |
| abstract | Preservation of wood chips, pref. green wood chips, comprises treatment with a soln. of a bisulphite or sulphite of an alkali(ne earth) metal or ammonium, or their mixts. The treatment is carried out by spraying the chips in a pipe during their pneumatic transportation to the storage site, the soln. droplets which have not been adsorbed by the wood, chips in the pipe are subsequently deposited onto the chips in a centrifugal separator placed at the end of the transportation pipe. The soln. contains 2-8% SO2 the pH is 1-6. The method is suitable for preservation of wood chips during the open-storage before the calcium bisulphite cooking. Bisulphite or sulphite ions react with lignin thus preventing its condensn. which otherwise would result in lignin retention in cellulose during the subsequent cooking. The spraying reduces loss of chemicals. |
