| In order to better design and modification of peach post harvesting systems such as sorting, conveying and packaging, selected engineering properties and bruise susceptibility of two Iranian peach varieties (Elberta and Spring time) were determined. Physical and mechanical properties such as dimensions, mass, volume, projected area, surface area, sphericity, static friction and rolling resistance coefficients on various surfaces, firmness and compressibility were measured. Also, effect of cultivar, drop height (50, 100 and 150 mm) and contact surface material (fruit, steel and rubber) on the bruise area and volume were investigated. Analysis of variance results indicated that cultivar had a significant effect (p |
