摘要: 为了解决松散回潮工序烟块松散程度不足、片烟和薄片板结等问题，提出一种松散回潮机进风装置优化设计方案：1）改进松散回潮机的进风系统，进风位置由物料进口振槽上方改为物料进口振槽下方，并在热风管道底部增设排水装置；2）设计并加装热风导向风管，把原有的水平方向出风改为一定角度的向右下方向出风.经验证，改进后的松散回潮机片烟松散率提高 0.28%，薄片松散率提高7.12%；松散后片烟结块质量平均降低89.8%，蒸汽耗量降低 14.95%.Abstract: In order to solve the problem of lack of loosing and conditioning and tobacco block,an optimized scheme of inlet air device of resurgence machine was suggested.1)resurgence inlet air system was improved,location of inlet air was under tablet entrance vibration slot instead of above,and equipment of drainage was added at bottom of hot-air pipe; 2)hot air director was designed and added,direction of hot air was changed from horizontal to downward and offside.The velidation test results indicated that loose rate of tablet enhanced 0.28%,loose rate of reconstituted tobacco enhanced 7.12%,weight of tobacco block reduced 89.8%,steam consumption reduced 14.95%.
