title: Effect of moisture content and residence time on dehulling of flaxseed.
abstract: 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.
