The Research Of Watermelon Seed's Rupture Mechanism

Watermelon seed's processing and research attracted wide attention from all walks of life, Realization the watermelon seed's pretreatment was the first step of processing and has important practical significance. But watermelon seed's irregular shape, smaller clearance between the shell and kernel, the shell's texture hard and combining closely, causing seam ruptureing open.So it's especially important to Research the ruptureing mechanism,such as related properties and stress distribution by theory.Thus provide the theory basis and the technical parameters for ruptureing process and equipment research.In understanding about the nuts and relevant materials of ruptureing mechanism and research methods and techniques at home and abroad,This topic analysis the watermelon seed's microscopic structure,physical properties and mechanical properties through the test.demonstrated the feasibility that the watermelon seed ruptureing in the compression loads.And choose watermelon seed's moisture content, shape and size, external load as influencing factors for test, the ruptureing strength and deformation as the index.Further analysis the relationship between the various factors of watermelon seeds ruptureing, establish mathematical model, confirm the primary influencing factors.On the basis of the research, establishe watermelon seed's mechanical model, and analyze the distribution of stress and strain, get the conclusion that the stress state related to watermelon seed's shape and external load in addition to the elastic coefficient.give theoretically instruction f or watermelon seed's ruptureing, experience accumulated certain theoretical guidance of manufacture and improvement the watermelon seed's ruptureing equipment.
