Effects of moisture content and residence time on various dehulling parameters of flaxseed including yield, hull, hullability, extraction rate and embryo (dehulled flaxseed) recovery were studied. A laboratory model rice polisher/ dehulling machine and a laboratory model aspirator were used for dehulling and aspiration (hull separation), respectively. The dehulling experiments were carried out for moisture contents ranging from 1.9 to 7.8% wb and residence times from 20 to 50 sec in dehulling machine at 2000 rpm of abrasive disc (rotor) of the polisher. Both moisture content and residence time played an important role in dehulling of flaxseed. The optimum moisture range and residence time for dehulling of flaxseed were 1.9 to 4.5% wb and 40 sec, respectively.
研究了水分含量和停留时间对亚麻籽各种脱壳参数的影响，包括产量、皮壳、可脱壳性、提取率和胚（脱壳亚麻籽）回收率。使用实验室模型大米抛光机/脱壳机和实验室模型吸气器分别进行脱壳和吸气（壳分离）。在脱壳机中，在 2000rpm 的磨盘（转子）转速下，进行了水分含量在 1.9%至 7.8%wb 之间、停留时间在 20 至 50 秒之间的脱壳实验。水分含量和停留时间在亚麻籽的脱壳过程中都起着重要作用。亚麻籽脱壳的最佳水分范围和停留时间分别为 1.9%至 4.5%wb 和 40 秒。
