Effects of Pectin Enzyme Pretreatment on Wood Fiber Separation

To reduce the difficulty of fiber refining, and the energy consumption due to the fiber refining. The influence of different pectin enzyme treatment conditions on wood fiber refining and fiber yield by single factor method was studied. The results showed that pectin enzyme reduced the difficulty of fiber refining and improved fiber morphology. When the reaction temperature was 50℃, pectin enzyme concentration was 1.0% and the reaction time was 3h, using pectinase treated wood after separation by disc refiner, wood fiber size becomed smaller and single fiber ratio increased. Wood pretreated by pectin enzyme reduced the difficulty of fiber refining. When the reaction temperature was 50℃, pectin enzyme concentration was 1.0%, reaction time was 2 h, wood fiber yield was the maximum. And the maximum was 91.18%.
