【摘要】 随着西部大开发深入实施，作为中国第二大畜牧产业基地的新疆畜牧业将有更大的发展规划，饲料的需求量将不断的增加。多汁饲料的种植和加工，对提高畜牧业饲养水平，促进畜牧业可持续发展，都具有重大意义。因此在新疆积极开展饲用甜菜加工设备的研制，是非常必要的，具有重要的现实意义。　 本文就饲用甜菜加工技术进行了试验研究。通过理论分析和试验相结合的方法，分析试验数据揭示结构参数与试验指标之间的关系，确立加工设备的主结构参数的较优值，为饲用甜菜加工设备的研制提供理论和试验依据，初步研究表明： 1、通过试验装置和仪器对饲用甜菜的主要物料特性（包括外形、摩擦角及密度等）进行测定，结果表明饲用甜菜的平均密度比水的密度大，平均值为 1.04 ㎏／L，饲用甜菜含水量高达 86％，个体差异较大。 2、通过清洗方法的对比，采用滚筒式清洗试验装置，确定影响试验指标(泥沙残留量)的试验因素是滚筒转速、清洗时间、浸泡时间和水量大小；最后通过正交试验，确定影响清洗效果的因素主次顺序是 ADCB,其最优组合是 A2D2C3B3。 3、理论分析后,得出影响饲用甜菜切丝功耗和损失率的主要结构参数，通过正交试验确定影响饲用甜菜切丝试验指标的主要因素主次和最优水平组合，结论表明D1C1B2A2组合最佳，此时梳型刀厚度0.4㎜、大刀倾角-1.5°、转盘转速480r/min、大刀与梳型刀间隙为 4.5 ㎜；应用二次回归试验，确定了饲用甜菜切丝机主要结构参数与试验指标之间的数学方程式，求解数学方程式得出，当功耗与损失率最小时，主要结构参数的较优组合是大刀倾角为 0°，转盘转速为 497.7 r/min，梳型刀厚度为 0.4 ㎜，最后通过验证试验，验证功耗与损失率的结果与数学方程式所得结<WP=8>果吻合，因此回归分析后的结果可以作为设计的依据。更多还原

【Abstract】 With the thorough implement of the large-scale developing of China’s westernregion, as the secondary industrial base of livestock farming in China, the Xinjiang’slivestock farming will encount greater developing programme. So the demand volumeof forage will be increasing gradually. It is of great significance to plant and processsucculent fodder beet for improving the feeding level of livestock farming andpromoting the maintainable development of livestock farming. So it is of greatimmediate significance and necessary to develop fodder beet’s processing equipment. The paper was aimed at the experimental research of fodder beet’s processingtechnique. Basing on the combination method of theory and experimental determination,we analyzed test data mainly, and revealed the relation between structure parametersand test quota for supplying theoretical and experimental basis of the development ofprocessing in equipment. The result showed that: ①Through test equipment and instrument ,some specific processing properties offodder beet were determined , including contour, friction angle and density etc, theresult showed that the average density of fodder beet is 1.04 ㎏/L, the moisture contentof fodder beet is very high, and reached to 86%,the individualof fodder beet is differentfairly. ②Contrasting some methods of washing, the instrument of cylinder washer wasadopted. The result of primarily test showed that test factors which influence testquota( silt remain) were rotation velocityof cylinder, washing time, soak time and sizeof water quantity. Finally, with orthorhombic test, the major-minor order of test factorswhich influence test quota was ADCB, and the best combination of test factors wasA2D2C3B3. ③Through theoretical analysis, the main structure parameters which influence testeffect of fodder beet’s filament cutter were rotation velocity of running plate,broadsword edge inclination, comb-type knife and the gap between comb-type knifeand broadsword. With orthorhombic trail, the major-minor order and best combinationof the main test factors were achieved, the result showed that D1C1B2A2 was the best 3<WP=10>one, that is , the thickness of comb-type knife was 0.4 ㎜, broadsword edge inclinationwas -1.5°, rotation velocity of running plate was 480r/min and the gap betweencomb-type knife and broadsword was 4.5 ㎜. Then we determined the mathematicalequation between parameters and quotas by quadratic orthogonal regression test, andthe solution of the equation attained the best combination of factors is that as thethickness of comb-type knife was 0.4 ㎜, broadsword edge inclination was 0°, rotationvelocity of running plate was 497.7r/min. Finally, trough proving test, the result of testwas identicalwith the result of mathematical equation, so mathematical equation can beused to design processing instruments of fodder beet更多还原
