Energy-Consumption Experiment of Pith-Stripping Mechanism of Rind-Pith Separation Equipment for Corn Stalk
摘要
Abstract
Electric power difference method was adopted to measure power consumption of the key mecha-nism---pith-stripping mechanism based on self-design rind-pith separation equipment for corn stalk . The four parameters,pith-stripping roll′s rotational speed,clearance between scrapers and supporting plate,feeding speed for corn stalk,and helix angle of scraper,were selected as experimental factors .Ef-fective specific energy(Ee),total specific energy(Et)and energy utilization ratio(ρ)were chosen as eval-uation indexes .Four-factor quadratic regression orthogonal rotation experimental design was applied .The effect models of all factors influencing evaluation indexes were obtained via response surface analysis . Within the range of the test parameters,the results were as follows:Ee was 0.5-2.0 Wh/kg,Et was 4.0-1 3.0 Wh/kg andρwas 1 1%-24%.Among three models,clearance and rotational speed of the pith-stripping roll had significant effect on three evaluation indexes,whereas the helix angle of scraper had little effect on total specific energy .Considering all evaluation indexes,production efficiency and quality of rind of corn stalk,the optimization tests showed that Ee ,Et and,ρwere 2.21 Wh/kg,1 0.73 Wh/kg and 22.29% respectively when pith-stripping roll′s rotational speed,feeding speed,clearance and helix angle were 840 r/min,41 3 r/min,1.56 mm and 25°respectively .These data could guide the design and optimization of rind-pith separation equipment for corn stalk .关键词
