Abstract

Saffron is the most expensive of agricultural products and pharmaceutical drugs in the world. Saffron is an herbal and reproduces by corms. Measurement of physical properties of SAFFRON CORMS are necessary for designing and optimization of harvesting, storage, transportation, grading and packaging equipments. The main goal is loss reducing and increasing the production quality. In this research, engineering properties including geometrical properties (dimensions, arithmetic mean diameter, geometric mean diameter, surface area, and sphericity), gravity properties (volume, true density, bulk density, and porosity), the FRICTIONAL PROPERTIES (coefficient of static friction, filling and emptying angles of repose) and AERODYNAMIC PROPERTIES (terminal velocity) were measured for SAFFRON CORMS. The effects of corms size in three levels (large, medium and small) and corms shape in two levels (with crown fibers cover and without crown fibers cover) were investigated on engineering properties in 30 replications. The results showed that the GEOMETRIC PROPERTIES means of SAFFRON CORMS with crown fibers cover was higher than SAFFRON CORMS without crown fibers cover. Although the volumes means of SAFFRON CORMS with crown fibers cover was higher than the corms without crown fibers cover, the means of true density, bulk density and porosity of SAFFRON CORMS without crown fibers cover was the higher than SAFFRON CORMS with crown fibers cover. This is possibly due to the fact, the crown fibers cover of corms increased the coefficient of static friction. The results showed that the lowest of static friction coefficient was related to wood and plastic surfaces. The emptying and filling angles of repose were obtained as 36.25, 52.89o and 23.98, 26.90o for SAFFRON CORMS with crown fibers cover and without crown fibers cover respectively. The terminal velocity means of SAFFRON CORMS for both with and without crown fibers cover were 8.89 and 11.62 ms-1, respectively.
