Unit energy of Miscanthus x giganteus stem cutting
Journal Title: Annals of Warsaw University of Life Sciences- SGGW - Agriculture - Year 2015, Vol 66, Issue 66
Abstract
The objective of the study was to explain the impact of moisture content in Miscanthus xgiganteus stem and the angle of positioning of the stem in relation to the cutting blade edge on unit energy of cutting. Research was conducting using Miscanthus xgiganteus plants of moisture content ranging from 6.83 to 49.83%. The stems were placed in a gripper, which allowed for changing of the angle of positioning of the stems in relation to the cutting knife blade edge (the angle was changed by 15° each time). To measure the cut, a steel knife of the width of 60 mm, thickness of 10 mm and blade angle of 30° was used. The average unit energy values of the cut for the examined conditions ranged from 0.10 to 60.18 mJ mm-2. It was shown that modification of the angle of positioning of the stem in relation to the edge of the cutting blade from perpendicular to parallel results in a substantial decrease in the unit energy of the cut. Increasing of the moisture content above 21.63% did not bring a statistically significant difference in the unit energy value of the cut.
