Abstract

The threshing quality of the machine was affected by moisture content. This parameter was one of the main causes of production losses. In Ethiopia, this problem was highly observed in the farm area during threshing. Therefore, the main aim of this research was, to minimize production losses during threshing by reducing the effect of moisture content on the crop, to improve threshing capacity, threshing and cleaning efficiency, to reduces fuel consumption, and to minimize grain damage by the machine during threshing. The experiment was done at four-time replication in the moisture level of 14%, 18%, and 22% for three selected cereal crops (barley, wheat, and tef) with a completely randomized design (RCBD) and 4 replicates as block giving 12 total experimental units. Crop moisture content, size of the grain, sphericity, angle of repose, density, thousand grain mass and coefficient of friction as well as threshing capacity, threshing efficiency, cleaning efficiency, germination rate, fuel consumption, and grain breakages were the parameters used to evaluate the performance of the thresher. Threshing capacity, threshing and cleaning efficiency, and density of grains showed decreased, as moisture content of crops increased. The other parameters mentioned above were increased with moisture content. A combined mean analysis of variances on the performance of thresher was significant at (p˂0.05). The recommended amount of moisture content in this study was 14% because the result obtained by 14% moisture level was preferable to other moisture levels. At 14% of moisture content, the threshing capacity was (208.750, 285.45 and 68.181) kg/hr, threshing, and cleaning efficiency (%) were (98.603, 99.330 and 99.49 and 97.101, 98.22 and 93.731 respectively). Percentage of germination rate was (94.25, 94.50, and 91.25) and the amount of fuel consumption was also (1.14, 1.72, 1.70) l/hr., for barley, wheat, and tef crops respectively.

水分含量对几种谷类作物脱粒机脱粒性能的影响

机器的脱粒质量受水分含量的影响。该参数是造成产量损失的主要原因之一。在埃塞俄比亚，这个问题在打谷期间的农场地区被高度观察到。因此，本研究的主要目的是通过降低水分含量对作物的影响，最大限度地减少脱粒过程中的生产损失，提高脱粒能力、脱粒效率和清洗效率，降低燃料消耗，最大限度地减少脱粒过程中机器对谷物的损害。试验采用完全随机设计(RCBD)，以大麦、小麦和tef 3种谷类作物为研究对象，在水分水平为14%、18%和22%的条件下，进行4次重复，共12个试验单位。以作物含水率、籽粒大小、球度、休整角、密度、千粒质量、摩擦系数以及脱粒能力、脱粒效率、清粒效率、发芽率、耗油量和破粒率作为评价脱粒机性能的参数。随着水分含量的增加，籽粒的脱粒能力、脱粒和清粒效率以及籽粒密度均呈下降趋势。以上参数均随含水率的增加而增加。脱粒机性能的综合平均方差分析显著(p小于0.05)。本研究中推荐的水分含量为14%，因为14%的水分水平比其他水分水平得到的结果更好。在水分含量为14%时，脱粒量分别为208.750、285.45和68.181 kg/hr，脱粒率和净粒率(%)分别为98.603、99.330和99.49,97.101、98.22和93.731。发芽率分别为(94.25、94.50、91.25)，耗油量分别为(1.14、1.72、1.70)l/hr。，分别用于大麦、小麦和大豆作物。
