Abstract

Physical properties of saffron flower in order to provide useful data for design of its processing equipment were investigated. The properties including dimensions, mass, true and bulk densities, porosity, static and dynamic coefficients of friction and terminal velocity as a function of moisture content were determined. The average range of variation for three different parts of saffron flower was about 0.03 to 0.16 gcm-3 for bulk density, 0.55 to 1.56 gcm-3 for true density, and 85.2 to 95.5% for porosity. The coefficients of friction of the flower parts for three surface materials including plywood, iron, and galvanized steel sheets were identified. The minimum and maximum values of static coefficients of friction were found on galvanized steel sheet. They were 0.8 and 2.14 for anther and stigma, respectively. The dynamic coefficient of friction was ranged from 0.45 for anther on iron to 1.14 for petal on galvanized steel sheet. The variation range of terminal velocity for three different parts of the flower was recorded between 0.9 and 2.38 ms-1. The obtained results of friction coefficients and terminal velocity values showed that the design of a separator of flower’s parts is feasible.
