种子加工是种子物料在场上作业,净度达到90%以上之后,向着更高商品化的进一步深加工。其中,清除种子物料中的各种杂质是种子加工实现商品化的首要环节。人们希望种子的净度越高越好,但越高难度也就越大,犹如提炼纯金,只有99%以上,没有100%。认识并理解这一规律性,对科学合理的选用种子加工机械,很有必要。种子杂质千奇百怪,性质不同按几何尺寸分,有大杂小杂;按长短分,有长杂短杂;按
Seed processing is the seed material on the field operations, net clarity of more than 90%, toward further commercialization of further processing. Among them, the removal of various impurities in the seed material is the first step in commercialization of seed processing. It is hoped that the higher the clarity of the seeds, the better, but the higher the degree of difficulty, the greater the purity of the seed, just above 99%, not 100%. Understanding and understanding of this regularity, the scientific and rational selection of seed processing machinery, it is necessary. Variety of seeds of various strange, according to the geometric size of the points, a large miscellaneous Miscellaneous; according to the length of points, a long miscellaneous hybrids; press
