Test and development of an non-thermal tartary buckwheat huller
摘要
Abstract
To solve the problem of tartary buckwheat nutrient loss in the traditional boiled hulling process,a new method of nonthermal tartary buckwheat dynamic-pressure grinding hulling was proposed and a hulling machine that had a pressure dynamic adjusting device is developed based on the analysis to the structural feature of tartary buckwheat and the structural defect of exsiting hulling machine.Through single factor experiment,the values of influencing factors was determined,the regression modeles of hulling ratio and perfect kernel ratio were then established respectively by quadratic orthogonal rotary combination tests.Multi parameter optimization was used to determine the optimal parameter combination:Grinding chamber gap 2.6 mm,grinding gasbag pressure 22.3 kPa,robbing chamber gap 4.0 mm,robbing gasbag pressure 5.1 kPa,spindle speed 470 r/min.Under this condition,the perfect kernel ratio and hulling ratio of tartary buckwheat in verification test were 31.8％ and 88.1％,respectively.The test result showed that primary reason was the dynamic pressure adjusting device didn't work well which resulting in dissatisfactory performance of tartary buckwheat hulling.关键词
