采用对置气流粉碎机对流床分离高水分稻草(SERS)中纤维组织与非纤维组织(包括表皮组织、薄壁组织和维管组织)的分离程度进行了研究。对分离出的纤维组分的化学组成和纤维尺寸、组成细胞比例等纤维特性进行了研究。分离过程可获得70.4%的高纤维含量、63.1%的纤维细胞含量和65.6%的纤维素含量。分级后的纤维组分的纤维组织分离度为2.04。平均纤维长度为0.97 mm，略长于未处理稻草。这种新方法适用于生产高纤维组织含量的馏分，而不会对原始纤维造成广泛的损害。(C)2006年，爱思唯尔有限公司出版。
Fractionation of fibrous fraction from steam-exploded rice straw (SERS) of high moisture content have been studied with respect to the separation degree of fibrous tissue from non-fibrous tissue including epidermal, parenchymatous and vessel tissue using a fluidized bed opposed jet mill. Chemical composition and fiber characteristics, such as fiber size and composed cell proportion were studied for the separated fibrous fraction of SERS. 70.4% high cellulose fibrous fraction with 63.1% fiber cell content and 65.6% cellulose content was produced from the fractionation process. The separation degree of fibrous tissue of the fractionated fibrous fraction was 2.04. The mean fiber length was 0.97 mm, slightly longer than the untreated rice straw. The new method is suitable to produce high fiber tissue content fractions without damaging the raw fibers extensively. (c) 2006 Published by Elsevier Ltd.
