Modeling Separation Process for Sunflower Seed Mixture on Vibro-Pneumatic Separators

نویسندگان

چکیده

Aim of the research is to increase efficiency mechanical and technological process separation sunflower seed mixture on vibro-pneumatic separators, principle which based interaction flow with surface having fluctuation-type vibration load by substantiating their efficient processing parameters. A system differential equations seeds motions, as a granular gas, under action vibrating was developed, taking into account elastic-damping physical properties seeds. The presented basis mathematical means numerical modeling this process, implemented in software package STAR-CCM +. To build models, it assumed that are form ellipsoids certain density effective diameter. As result simulation moving sieve, dependences change total concentration θ productivity q supply Q, sieve angle α, frequency ψ amplitude were obtained. surface, filling factor χ, distribution coefficient δ angles α β, oscillation ψ, set air velocity V Theoretical provisions tested development an adaptive screen separator (Ukrainian patent #120235).

Seed Distribution Uniformity of Sunflower

In this study, four different type seeders were evaluated for seed spacing, depth uniformity, and plant emergence at three forward speeds (3.6, 5.4, and 7.2 km h-1). The planter types were: no-till planter, precision vacuum planter, universal planter, and semi-automatic potato planter. The sowing uniformity of the horizontal distribution of seeds was described by using the multiple index, the m...
