本发明高粘性物料制粒无尘生产系统是在生产常规物料工艺参数基础上，将湿法制粒机搅拌浆速度减小，提高切割刀速度，进而增加了切割刀与物料的切割次数。
本发明的高粘性物料制粒无尘生产系统运行时，启动系统，将称量后的粉料用真空上料方式，加入湿法制粒机的锅体内，开启相应的低速搅拌和切割，而后通过压力加浆罐将浆料压入锅体内，开启高速搅拌，可通过锅盖上的视镜观察物料成型情况。本发明的湿法制粒机在常规的物料生产工艺参数基础上，减小浆料输入到锅体后的高速搅拌机的浆料搅拌速度，并提高相应的切割刀速度，增加切割刀与物料的切割次数。
制粒完成后，开启摇摆制粒机，沸腾干燥机加热器，引风机(或预干燥风机)，打开湿法制粒机的出料门，搅拌浆低速转动将物料输送到沸腾干燥机，干燥过程中，根据干燥的进行程度，不断调整风机频率，进风阀(冷/热风进风控制阀)开口角度，及蒸汽比例调节阀。干燥完成后，打开沸腾干燥机的真空出料口、真空上料机及提升真空整粒机，暂不打开真空提升整粒机缓冲罐的手动出料阀门(缓冲罐容积与沸腾干燥机的产能配套，保证物料能一次性抽完)将物料输送至真空提升整粒机缓冲罐，同开打开脉冲除尘。输送完后，关闭真 空上料机及脉冲除尘，打开整粒机，整粒机出料口通过防静两层式布袋与周转料筒对接，实现密闭无尘。下料整粒过程中如出现堵料和架桥现象，可开启气锤式振动器敲击罐壁。
本发明的另一实施例中，如图9所示，其提升真空整粒机设有提升真空上料装置，提升真空上料装置包括除尘罩壳38、旋转式机架32、手摇控制装置31、除尘布袋34、脉冲除尘装置等。所述提升真空整粒机的料桶3a通过除尘罩壳连接有一导料管39。除尘罩壳38的顶部开设有一吸风口35，其除尘罩壳通过吸风口35与相应的真空上料机20连接。除尘罩壳38的下端口与相应的提升真空整粒机3的料桶3a的进料口对应可气密性连接，其外径远小除尘罩壳的下端口的相应的内径的导料管39的一端、自除尘罩壳8的内腔插入并延伸出除尘罩壳的下端端口至料桶3a内，作为进料口的导料管39的另一端自除尘罩壳38的相应一侧壁延伸出除尘罩壳外部，且导料管39的该另一端与除尘罩壳的相应罩壁为气密性连接固定。
提升真空上料装置可通过连接于其除尘罩壳38与旋转式机架32之间滑轮机构，以及连接于滑轮机构与旋转式机架2之间的手摇控制装置31旋转升降式连接于旋转式机架32上。其脉冲除尘装置包括设于除尘罩壳38内的若干除尘布袋34，脉冲控制装置33包括有连接于除尘布袋的控制阀及其相应脉冲控制器。
其除尘罩壳38的相应的一侧连接有一安全阀，以控制其除尘罩壳和料桶3a内的负压极限。
当需要对料桶3a上料时，将除尘罩壳通过手摇控制装置移至料桶3a的进料口处，并使除尘罩壳的下端口与料桶3a的进料口气密性对接，并用卡箍固定。将导料管的作为进料口的该另一端与相应的沸腾干燥机的输出口连接，即可对料桶3a真空上料。上料过程中可由脉冲控制装置设置脉冲除尘时间和脉冲除尘间隔。不上料时通过手摇控制装置将旋转式机架旋转移离于料桶3a，不占工作空间，并可同时为多个相应的无尘生产系统供料。
