digester/digester room Explanation: crec que 'digester' et servirà; encara que es veu que parla d'un mètode més antic de fer paper es el mateix procès. http://palimpsest.stanford.edu/don/dt/dt1023.html "A vessel in which pulpwood, straw, esparto, rags, or other cellulosic materials are treated with chemicals and heat to produce the pulp used in the manufacture of paper. A digester is usually constructed to withstand elevated pressures and is made of materials designed to resist the chemicals used in pulp preparation. Digesters may be cylindrical, spherical, horizontal, vertical, stationary, rotating or designed to tumble. Most are stationary. A digester may be designed for batch operation, in which it discharges its pu lp at the conclusion of a fixed cycle, or it may be designed for continuous operation, in which case it moves the raw material and chemicals at a fixed rate from the charging end to the discharging end." http://internationalpaper.com/Our Company/Learning Center/Ho... "To accomplish this, the chips are loaded into large vessels called digesters on either a batch or continuous basis. Digesters are designed on the same principle as a kitchen pressure cooker. The chips and chemicals are steamed under pressure for 1.5 to 4 hours until the mixture is reduced to a wet, oatmeal-like mass. The cooking frees the fibers so they can be suspended in water." |
