| Abstract:In this paper， the determination of pith content of bagasse was carried out by using the Standard Top hit Vibrating Screen， the Standard Slap Vibrating Screen and the Digital Speed Controlled Multi purpose Oscillator respectively. The pith was screened and analyzed， to evaluate the effect of screening equipment on screening of bagasse pith. Results showed that the pith content measured by different devices was different， which was attributed to the movement mode of the equipment. The holocellulose content of pith was more than 80%， while the lignin content was only about half of the content of bagasse. The average length and width of the cells in pith were smaller and they had more concentrated distribution. Through morphology observation， great amount of fine fibrous cells could be found in bagasse pith in addition to contain more parenchyma cells. |
