摘要
采用正交试验设计的方法研究了造粒方式、物料含水率、造粒次数对膨胀烟梗造粒过程中物料损耗率、造粒得率及所制备的成品颗粒填充值的影响。结果表明:①造粒方式对物料损耗率、造粒得率及成品填充值的影响均达到了显著水平,F值分别达到12.208,5.59,10.372,贡献率为42.898%,53.410%,59.822%;②造粒次数对造粒得率的影响也较大,F值达到11.919,贡献率为41.792%;③物料含水率对各指标影响有一定的影响,但影响程度不显著;④综合各项试验指标,锤片式造粒是颗粒梗制备工艺中一种较好的造粒方式,物料含水率30%左右、造粒次数2～3次比较合理。
The effects of granulation methods,stem moisture contents and repetitive granulation on stem waste,granulous stem yield and filling power were studied by orthogonal experiments.The results showed that： 1） granulation method significantly influenced stem waste,granulous stem yield and filling power,the F values of significance test were 12.208,5.590,10.372 with the contribution rates of 42.898%,53.410%,59.822%,respectively;2） repetitive granulation also obviously affected granulous stem yield,the F value and contribution rate were 11.919 and 41.792%,respectively;3） stem＇s moisture content affected these experimental results as well,but not significant;4） on the whole,hammer granulation was a better method for preparing granulous stem.The suitable stem moisture content was about 30% and repeated granulation for 2 to 3 times.
