| Measuring physical properties of crops is necessary for optimal harvesting, cleaning, threshing, sorting, drying, and milling operations. Despite an extensive literature review, there is no information about the physical properties of the wild safflower seed. In this study the physical properties of the wild safflower seed have been investigated as a function of moisture content at four levels (5.4%, 9.4% (initial), 13.4%, and 17.4% d.b.). The average length (mm), width (mm), thickness (mm), arithmetic mean diameter (mm), geometric mean diameter (mm), sphericity (%), volume (cm³), seed surface area (cm²), terminal velocity (m/s), bulk density (gr/cm³), actual density (gr/cm³), and porosity (%) at initial moisture content were 6.418, 3.499, 3.388, 4.435,... |

| Abstract Parboiling is a pre-dehulling operation and, the effect on the physical properties of African breadfruit seed (var. africana) was investigated. Freshly extracted seeds were parboiled for 0 (control), 5, 10, 15, and 20 minutes, and their physical properties determined. It was observed that parboiling time had a significant effect (p<0.05) on all the physical properties of African breadfruit seeds investigated. The moisture content of the seed ranged from 32.92±0.23 to 50.78±0.19 % (w.b.) as the parboiling time increased. Generally, it was observed that the mean values observed for the physical dimensions (axial dimensions, mean diameters, sphericity, aspect ratio and surface area) increased from 0 to 10 min. parboiling time after which the... |

| OranOrange has abundant nutritional properties and is consumed worldwide. Sorting oranges of different masses based on their physical traits could help reduce packaging and transportation cost. The ‘Blood’ cultivar of Iranian oranges from Kermanshah province of Iran (7.03 °E 4.22 °N) was used in this study. 100 samples were randomly selected. During the two-day experiment, all measurements were carried out inside the laboratory at mean temperature of 24°C. In this study, some physical properties of ‘Blood’ orange were measured, such as length, width, thickness, volume, mass, mean value of geometric diameter, sphericity and projected area. ANFIS and linear regression models were employed to predict the mass based on sphericity and mean of projected... |

| The physical and mechanical properties of agricultural products have an effective role in determining the quality of the products, reducing the potential damage caused by transportation and eventually designing the equipment used in the processing of the products. In this study, some physical and mechanical properties of snake melon were measured under standard conditions. Physical properties included length, width, thickness; mean diameter (geometric and arithmetic), sphericity, surface area, aspect ratio, mass, volume and density. The mechanical properties of the samples and their lengths were measured under the conditions of pressure (bruise), bending (break) and cutting of the snake melons in halves using a Zwick/Roell Instron testing machine based on... |

| In avoiding damage to fruit species, the permissible falling height and permissible static pressure are of great importance. The former is important in planning harvesting and handling operations, the latter in selecting the height of transport containers. Fruits are generally transported in containers. The static and dynamic forces which then act on the fruit will cause damage if they exceed given value. The static force may be calculated from the weight of the fruit column being transported while the dynamic load is a consequence of vibration caused by transport. The permitted static load for a given fruit may be determined experimentally. The aim of this study was design of a suitable height based on the measured properties using Ross and Isaacs’s... |

| Used Azivash seed in the research has been provided in summer 2013. The samples were cleaned and separated manually and residuals and broken seeds were taken apart it and healthy seed was provided for testing. Then diameter, area of image, and round coefficient, were calculated using image processing application. Mass of 1000 seeds, mass density, real density and porosity percentage, static friction coefficient, repose angle in two modes of fullness and emptiness were measured. Liquid replacement method has been used to calculate density and volume of the seeds. The results showed that a positive relationship between physical properties of Azivash seed including geometric properties (diameter, volume), gravity properties (weight of 1000 seeds, real density... |
