本发明涉及卷烟/卷烟滤棒生产设备，特别是一种制备全颗粒卷烟/滤棒的设备、方法及制备的全颗粒卷烟/滤棒。
背景技术
传统卷烟均是由烟丝制备而成，而全颗粒卷烟/滤棒是由再造烟草颗粒制备而成的。全颗粒卷烟与烟丝型卷烟相比有其独到之处，但现有卷烟机或成型机都无法制备全颗粒型卷烟/滤棒。卷烟滤棒是卷烟生产中重要的辅助材料，近年来滤棒颗粒添加剂是研究热点之一，通常而言颗粒添加剂均匀添加于醋纤丝束中制备颗粒复合滤棒，或者以集中松散填装的方式制备三元复合滤棒的方式应用，这会导致滤棒的生产和使用成本大幅增加。有研究者提出将滤棒颗粒添加剂制备成整体全颗粒棒，但如何实现全颗粒棒的连续化生产一直没有得到很好的解决。
如何将再造烟草颗粒或滤棒颗粒添加剂连续成型制备成全颗粒的烟棒或颗粒滤棒，用于卷烟/卷烟滤棒的生产成了摆在卷烟/卷烟滤棒生产设备企业面前的一个重要课题。
