| Abstract:The disadvantages of high consistency refining which is commonly used in reconstituted tobacco sheets manufacture was analyzed and two steps low consistency refining process was described. The high and low refining effect on the fibers characteristics and the sheet properties were compared. The results showed that low consistency refining can the disadvantages of high consistency refining. Compare to high consistency refining, low consistency refining improves the fiber length by 10.8%, the width of fiber drops by 17.8%, coarseness reduces by 9.5%, kinked fibers, broken fibers and softness are also lower than that of high consistency refining. |
