为了得到把鸡粪膨化成饲料的最佳膨化工艺参数,在开发的鸡粪专用膨化机上,采用正交试验对鸡粪进行了膨化试验。研究结果表明:模板孔直径为主要因子,其次为物料含水率和小麦麸比例;最佳组合是物料的含水率为20%,小麦麸的比例为15%,模板孔直径为4mm。
In order to get the puffed chicken feed into the best puffing process parameters, in the development of chicken manure dedicated puffing machine, the use of orthogonal test of chicken manure puffing test. The results show that the diameter of the template is the main factor, followed by the moisture content of the material and the proportion of wheat bran. The best combination is that the moisture content of the material is 20%, the proportion of wheat bran is 15% and the diameter of the template is 4mm.
