Design and experiment of cone disk centrifugal shellfish seeding device

This paper designed a centrifugal shellfish seeding device with conical disc structure to improve the efficiency and uniformity of device. The dynamic model seedling moving on disk is established, main parameters affecting seedling’s movement characteristics are determined as cone angle impeller, speed offset blade. Using EDEM software seedlings blanking rate influencing factors, single factor simulation test was performed. research found that variation trend distribution in statistical area gradually decreased along horizontal direction both sides, origin being center sowing Test orthogonal rotation simulations using coefficient effective job width evaluation indicators. Use Design Expert optimize based results, determine optimal maximum minimum constraints: impeller 7.72°, blade -0.9°. above-mentioned for actual testing. results show when 750r/min 0.65kg/s, 12.84% 24.98m, respectively, while 13.77% 23.25m, respectively. object performance commonly used size Philippines clam. showed speed, rate, quadratic term size, interactive had significant effects ( P <0.01). Shellfish all impact this study provide reference mechanized design seeding.
