    Abstract:

    With the aim of increase the quality of flaxseed,SLG67-18.5 twin-screw extruder was used to investigate and optimize the effect of diameter of mould,crushed granularity, temperature,moisture content,rotation speed of screw and feeding speed on removal rate of HCN in flaxseed and extrusion intensity.Mathematic expressions of removal rate of HCN,in vitro protein digestibility and mould pressure was set up by quadratic regressive currency rotary design.And the optimum conditions were listed as follows temperature,moisture content, rotation speed of screw and feeding speed 156℃,16.6%,219 r/min and 76.1kg/h respectively. The results presented here provided knowledge to the development and use of flaxseed,and to the operation and adjustment of the existing extruders.
