| Abstract | ||||
| Physical properties are the most important in the design of equipment and processing systems. Among the physical properties; dimensions, mass, volume, surface area and projected area are the most important parameters in processing systems. Grading fruit based on weight reduces packing and handling costs and also provides suitable packing patterns. In this study, physical properties of pomegranate were determined, and mass modeling with some physical properties was applied based on three classifications: (1) single or multiple variable regressions of pomegranate dimensions, (2) single variable regression of pomegranate surface area, and single or multiple variable regression of pomegranate projected area and (3) estimating pomegranate mass based on its volume. Results showed that mass modeling of pomegranate based on major diameter and first projected area are the most appropriate models in the first and second classifications, respectively. In the third classification, the highest R2 was obtained for mass modeling based on the actual volume as 𝑅2 = 0.998, whereas corresponding values were 0.942 and 0.918 for assumed pomegranate oblate spheroid and ellipsoid shapes, respectively. In an economical view, a suitable sizing and grading system of pomegranate mass was justified based on major diameter as linear relation 𝑀 = 8.7004𝑎 - 470.33 , 𝑅2 = 0.932. | ||||
