1影响种子破碎率的主要因素一是种子品种。在同一加工线流程中,含淀粉量较高的种子比含蛋白质高的种子显现出更高的破碎率。二是种子的脱水速率及种子含水量多少对种子的破碎率影响很大。脱水速率过大易造成种子产生裂纹而在后续破碎,含水量大于18%时,种子在脱离时易引起种子胚部破裂,含水量低于13%时,种子在脱粒时由于“过硬”而引起撞击产生裂纹。三是种子加工生产线建设的工艺方案、工艺流程、设备选型等因素对种子加工过程中种子破碎产生重要影 A main factor affecting the rate of seed crushing First, the seed varieties. In the same processing line, higher starch content seeds showed higher fragmentation rates than protein-containing seeds. Second, the rate of seed dehydration and seed moisture content of the seed crushing rate greatly affected. Dehydration rate is too large to cause cracks in the seeds and the subsequent crushing, when the water content is greater than 18%, the seed is easy to cause seed embryo rupture when the seeds are detached. When the water content is less than 13%, the seeds are “too hard” Crash caused by the impact. Third, seed processing production line construction process plan, process, equipment selection and other factors on seed processing seed crushing have an important impact
