Abstract

In this study, rupture force and deformation in rupture point of three varieties of sunflower seeds (almond, round, white, thin) in loading speeds of 10, 25, 40 and 55 mm per minute and in two longitudinal and lateral direction in 10 replications in a factorial experiment in completely randomized design were investigated. Results showed that main effect of variety and main effect of loading direction for rupture force was significant at level of 1%. And the main effects and binary interaction and triple interaction of factors loading speed, loading speed × variety , loading speed × loading direction, loading direction × variety, and loading speed × loading direction× variety for rupture force was significant at level of 5%. And also the main effects and binary interaction and the triple interaction of factors except for the binary interaction between loading speed ×Direction loading was significant at level of 1%. The highest rupture force in lateral direction at the speed of 55 mm per minute has been calculated to the amount of 60.027 N. And also the lowest rupture force in the longitudinal direction at the speed of 55 mm per minute has been determined to the amount of 26.225 N . And the highest rupture force in the lateral direction for the variety of pen has been calculated to the amount of 57.73 N. And the lowest rupture force in the longitudinal direction for the variety of pen has been determined to the amount of 2.25 N.Also the highest rupture force for the variety of almond at the speed of 25 mm per minute in the longitudinal direction was obtained to the amount of 47.337 N and the lowest rupture force for the variety of tin at the speed of 55 mm per minute in the longitudinal direction was obtained to the amount of 20.156 N. the highest deformation for the variety of white round at the speed of 40 mm per minute in the longitudinal direction was obtained to the amount of 1.251 mm and the lowest deformation for the variety of thin at the speed of 55 mm per minute in the longitudinal direction has been determined to the amount of 0.336 mm.
