中文摘要 | 為將青割玉米壓擠成方塊,以便運輸搬至貨櫃內青貯,須先研製一台青割玉米方 包裝填機,試驗初期,先對青割玉米一些基本物性做量測與分析,以此作為青貯裝填雛型機 之設計依據;取樣量測的秋作青割玉米其含水率為71.4%,以莖部含水量較高,平均之細斷 長度為19.7mm,虛表比重為0.221。在青貯技術層面上,壓縮比可決定青貯玉米之裝填密 度及評量青貯時空隙率及壓擠後方塊的大小,設計一壓縮試驗裝置,得出青割玉米之裝填壓 力(GP)對壓縮比(CR)之關係;其迴歸方程式為CR=1.455×Ln(GP)-1.964,決定係數為0.998。 當裝填錶壓力達錶壓60kg/cm 時,有大量水份滲出,因此裝填錶壓力以50kg/cm 為設計 準則。 |
英文摘要 | A Feeding machine for forage corn was developed to compress it as a cube-shape in order to move to cargo for storage. Physical properties of forage corn were measured and analyzed as a design basis for prototype of Feeding machine. Moisture content of experimental samples of forage corn, which grown in Autumn, was 71.4%, and moisture content in part of stem was highter. The abverage length and bulk density of samples were 19.7mm and 0.221 respectively. For the technique of silage, bulk density, sealing, and size could be decided by compression ratio. An experimental setup for compression tests was developed to obtain the relationship between gage pressure Gp and compression ration CR, regression equation to be CR=1.455ln(GP)-1.964 and the coeficient of correlation to be 0.998 Lost of water leaked out as gage pressure above 60kg/cm . Hence, design criterion would be based on gage pressure to be 50kg/cm . |
