Sunflower Seed Suction Stability Regulation and Seeding Performance Experiments

نویسندگان

چکیده

The poor adsorption stability of the current air-suction sunflower seed-metering devices under high-speed operation leads to unstable seed posture, as well increases in multiple and miss indices. In order improve adsorption, an device based on structure-assisted stable suction posture was designed, movement mechanism absorption process seed-feeding is analyzed, following which mathematical models processes are established, key factors affecting seeding performance were determined. Furthermore, shape parameter equation seeds fitted, depending dimensions parameters, provides design basis for components device. Moreover, optimize structure, taking depth, width, length grooves experimental factors, qualified, multiple, indices evaluation indices, orthogonal regression experiment considering three levels carried out using Box–Behnken design. Finally, established extreme value theory used parameters influencing obtain optimal combinations. combination follows: width groove, 10.5 mm; 3 length, 23 mm. Results from verification experiments revealed corresponding indicators, qualified index 91.63%, 5.63%, 2.74%, thus meeting requirements effective sowing.

Flavor and Oxidative Stability of Northern-Grown Sunflower Seed Oil

Flavor and oxidative stabilities of a northerngrown sunflower seed oil were investigated. Taste panel and oxidative evaluations were made on alkalirefined, deodorized, unbleached samples treated with commercial antioxidant mixtures, phenolic antioxidants, metal scavengers and added trace metals. Similar evaluations were conducted on a sample of the same oil after bleaching. Commercial antioxida...

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...
