摘　　要：采用LNI-610-30分级式冲击磨粉碎设备,在干法状态下分别使用陶瓷和不锈钢2种打击轨道粉碎全脂大豆。结果表明:国产设备有能力制备平均粒度为7.5μm的超细全脂大豆粉;试验得到样品的粒径分布和粒度大小与标准样品相近,且试验设备产量大、效率高,能耗约为气流粉碎设备的三分之一;但是豆粉溶解度和生成产品的口感不理想,粉碎温度偏高,设备内部粘附现象严重。In order to confirm domestic equipments have ability to produce ultra-fine full-fat soybean powder, LNI-610-30 classify-impact equipment was used to crash full-fat soybean under dry method, the experiment was carried out by using ceramic impacting orbit and stainless steel impacting orbit respectively. Japanese ultra-fine full-fat soybean powder which was produced by jet mill, supplied by VV Group was used as standard. According to the measuring of powder yield, particle size, system flow and temperature, the experimental samples＇ particles size and distribution were similar to the standard sample. Furthermore, compare with jet mill, LNI-610-30 has higher production and efficiency,its energy consumption was nearly as one- third time as jet mills. But higher crushing temperature led to adhesion of internal equipment, and also had adverse impact on experimental powder＇ s solubility and its product＇ s mouth- feel. Therefore, domestic equipments have ability to produce ultra- fine full- fat soybean powder that average particle size is 7.5 μm.
