Aiming at the problems of low efficiency and high cost of artificial peeling of Gleditsia sinensis rice and compli-cated hulling process,inadequate hulling cycle hulling and low hulling rate of existing mechanized Gleditsia sinensis seed hulling devices.Taking Gleditsia sinensis seeds produced in Bozhou City,Anhui Province after classification as the re-search object,this paper proposed a pretreatment process of cooking Gleditsia seeds with a certain concentration of tata powder and then drying them.Through the self-designed rolling Gleditsia seeds shucking device,with the rate of shuc-king as the evaluation index,through single factor test and orthogonal test,the peeling effects of cooking time,concentra-tion of tartar powder and drying time at different levels were analyzed.The results showed that peeling first increased and then decreased with the increase of the concentration of tartar powder.With the increase of cooking time and drying time,the peeling rate increased gradually and then becomed stable.The experimental data were analyzed by Design-Expert soft-ware,and the results showed that the order of significant influence on the peeling rate of Gleditsia sinensis seed from small to large was:cooking time,drying time,and concentration of tartar powder.The regression mathematical model of shuc-king of Gleditsia sinensis seed was established and a set of optimal parameter combinations were optimized.The optimal parameter combinations were cooking time of 90 min,concentration of tartar powder of 3%and drying time of 8 h.The ex-perimental results showed that the peeling rate reached 84.42%under these conditions.
