An Experimental Study on Squeeze Breaking Mechanism of Peanut Seeds

  • 摘要: 为获取花生种子挤压破碎特性,降低对其机械化作业时的损伤,对花生主产区典型品种的花生种子进行了挤压破碎试验,分析了不同品种、不同含水率、不同挤压位置下花生种子的挤压破碎性能.试验结果表明:花生种子在不同含水率、不同挤压位置下所能承受的最大挤压力均有所不同,最终随含水率增加而降低,而在不同挤压位置条件下,同一含水率的种子所能承受的挤压力由大到小依次为腹面、侧面、顶面;不同品种花生种子在同一挤压位置下抗挤压破裂能力也有所不同,其原因均与种子自身的内部组成、外形尺寸等因素有关.
    Abstract: In order to master the squeeze breaking mechanism of peanut seeds and reduce the mechanical damage, the squeeze breaking property of the peanut seeds of different varieties, under different moisture contents and different squeeze locations have been analyzed through the squeeze breaking experiments with the particle strength test instruments. The mechanical properties of peanut seeds of different varieties, under different moisture contents and different squeeze locations were analyzed. The experimental results showed that the maximum squeeze force of peanut seeds under the different moisture contents and different squeeze locations had significant differences. The maximum squeeze forces of peanut seeds were reduced ultimately with the increase of the moisture contents, and the maximum squeeze force of peanut seeds under the different squeeze locations and the same moisture contents followed in an order of the ventral side, the side surface and the top surface. At the same squeeze location, the maximum squeeze force of different varieties were different, which was related to the internal composition and dimensions of peanut seeds.
