进料阶段包括如下步骤：
A1、将新收获后的花生物料经过初步清选除杂后，经上料机构输送到二级振动筛分除土输送机构的输送带面上；
A2、振动作用下物料逐渐向前移动并将附着于花生表面的浮土逐渐振落，浮土掉落至一级土杂输送机构，并径一级土杂输送机构输送至二级土杂输送机构，二级土杂输送机构将土杂输送至干燥机外部；
A3、花生物料经二级振动筛分除土输送机构输送至无损提升机的下端进料段后，经无损提升机构向上输送到卸料管，落入上输送机，再由上输送机将物料输送至储粮室；
干燥阶段包括如下步骤：
B1、当花生物料填满储粮室和干燥室后，启动物料干燥***中的离心风机、供热部件，形成一股依次经过进风道、进风口、进风条形盒、出风条形盒、出风口、排风道的热气流；
B2、物料从两个排粮机构中缓慢流出，落入一级振动输送机构和二级振动筛分除土输送机构，其中落入一级振动输送机构的花生物料归集到二级振动筛分除土输送机构后，在振动作用下物料逐渐向前移动并将附着于花生表面的浮土逐渐振落，浮土掉落至一级土杂输送机构，并经一级土杂输送机构输送至二级土杂输送机构，二级土杂输送机构将土杂输送至干燥机外部，花生物料经二级振动筛分除土输送机构输送至无损提升机的下端 进料段后，经无损提升机提升输送至卸料管中，落到入上输送机，再由上输送机将花生物料输送至储粮室中；

出料阶段包括如下步骤：
C1、冷却花生物料，具体操作时，继续启动离心风机并停止供热部件的运行，以形成一股依次经过进风道、进风口、进风条形盒、出风条形盒、出风口、排风道的冷却气流；
C2、排出花生物料，物料从两个排粮机构中缓慢流出，落入一级振动输送机构和二级振动筛分除土输送机构，其中落入一级振动输送机构的花生物料归集到二级振动筛分除土输送机构后，花生物料进入无损提升机构下端进料段，经提升输送后将物料进入卸料向分支管，进入出料管后逐渐滑落至地面。
本发明的有益效果在于：
1)能够均匀干燥花生物料，干燥时热气流从进风道进入进风口，从而进入进风条形盒内腔，热气流从进风条形盒的透气孔透出，形成向上的气流和向下的气流，然后热气流进入相邻的出风条形盒内腔中，透过出风口进入排风道，在此过程中，干燥室内腔中就形成相对均匀分布的若干股对流式热气流，从而达到均匀干燥的效果；
2)干燥过程快速、高效、低耗且符合花生物料特性，在进行干燥时，花生物料依次经过底座组件、提升机构、卸料管、上输送机、储粮室、干燥室，且形成一个循环输送线路，可以不间断地对花生物料进行干燥，从而使得花生物料能够得到充分的干燥，并且使得干燥效率有所保障；
3)在干燥阶段以及进料阶段均可去除花生物料中包含的土杂，而且在 干燥时，花生物料被循环输送并反复经过底座组件，由振动筛输送组合部件输送花生物料并驱使花生物料进行不断的振动，以使得土杂不断落下，由土杂输送组合部件将花生物料振落的土杂输送到干燥机之外，从而实现在干燥过程中不断清洁花生物料的目的。
