浸梗工艺的改进试验

Improvement of Tobacco Stem Dipping Technology

为进一步改进复烤烟梗的预处理工艺,提高梗丝加工质量,降低梗丝消耗,采用新型刮板式浸梗机进行了该设备最佳工艺参数范围的确定和浸梗与水洗梗+蒸梗及二次贮梗3种处理方法对梗丝工艺质量及消耗等的影响对比试验。实际应用效果表明,浸梗法工艺在降低物耗和提高梗丝质量方面比水洗梗+蒸梗处理和二次贮梗法具有明显的优势;60℃、50s(刮板输送皮带电机频率24Hz)、贮存4h为刮板式浸梗机的最佳工作条件。

In order to improve the processing quality of cut stem and reduce the waste during stem processing, the optimal technical parameter range for new domestic rake type stem dipping machine was determined, and the effects of three processing methods, including stem dipping （SD） , stem washing ＆ steaming （SWS） and twice stem storing （TSS） , on the processing quality and waste of cut stem were comparatively experimented. The results showed that the SD was obviously superior to SWS and TSS in quality improving and waste reducing. The optimal processing parameters for the stem dipping machine were that the stem was dipped in water of 60℃ for 50s, and then stored for 4 hours; and the frequency for rake conveyor motor was 24Hz.
