The physical properties of agricultural products are very important for designing tools and machines for processing products. The quality of peanuts is determined by physical properties. The physical properties that determine the quality of peanuts are the air content and physical quality of seeds (whole seeds, wrinkled seeds, and damaged seeds). The physical properties of peanuts must be considered the size of peanuts (area and volume), true density, bulk density, porosity, angle of friction used for drying and storage. On Measuring the Physical Properties of Peanuts Various Types of Variations Each of which Has Different Values. In the measurement of the average large dimension value of the Talam 2 variety has a number of 14.48 ± 0.97, the average width value required by Takar 2 and Talam 1 varieties is 8.55 ± 0.57 and. Measure 2 has an arithmetic mean diameter value, geometric mean diameter, surface area, and overall volume as a whole - 9.9 ± 0.56, 9.62 ± 0.36, 291.05 ± 22.07, 468 , 03 ± 52.59. This happens because the Takar 2 variety peanut has a larger seed shape and more containing seeds. Glass is a friction surface that has the highest coefficient of static friction.

Rice is now the main food for about 35 million people in Nigeria, and consumption is increasing faster than that of any other food crop in many countries in Africa. This study provided essential engineering data on the physical properties of selected varieties of local rice in Nigeria. Some selected physical properties of Igbemo, Ofa- da and Abakaliki rice varieties at harvest, market, and storage conditions were evaluated as a function of moisture content. The latter ranged from 12.38 to 25.69% (dry base). We also determined the physical properties of the rice samples, such as moisture content, linear dimensions, geometric mean diameter, arithmetic mean diameter, surface area, aspect ratio, sphericity, bulk density, and hundred kernel weights. A result of the linear dimensions for the major diameter was 8.4–10.3 mm, 6.4–6.55 mm, and 5.9–7.4 mm for harvested, marketed, and stored rice, respec- tively. The minor diameter ranged from 2.70 to 3.29 mm, 2.49 to 2.63 mm, and 2.56 to 2.74 mm, and the intermedi- ate diameter of the rice varieties at harvest, market, and storage conditions was 1.92–2.29 mm, 1.90–2.02 mm, and 1.87–1.99 mm, respectively. Depending on the conditions and varieties, the bulk density, true density, and porosity, was observed to be between 0.59 to 0.90 g/cm3, 2.28 to 5.57 g/cm3 and 70.38 to 85.35% respectively.

Abstract Some physical properties of kumquat were investigated. Physical properties which were measured included fruit dimensions, mass, volume, projected area, density, geometric mean diameter, sphericity and surface area. Bulk density, porosity and also packaging coefficient were calculated. Mechanical properties such as the elasticity modulus, rupture force and energy required for initial rupture have been determined. The experiments were carried out at moisture content of 82.6% (w.b.). The results show that the kumquat fruit is one of the smallest fruit in the citrus family.

Abstract In this study some physical properties of fan palm (Washingtonia robusta) fruits, seeds and seed coats were determined using dimensional, bulk and single kernel physical analysis. The moisture content of whole fruits, seeds and seed coats was 12.0, 9.86 and 13.87% (d.b.), respectively. The sphericity values showed that seed shape (0.86) is close to a sphere, similar as the fruit shape (0.83), both of which were close to a scalene ellipsoid shape. The surface area values of fruits and seeds were obtained as 163.27 and 80.25 mm2, and volume values were obtained as 190.96 and 66.32 mm3, respectively. Bulk densities of fruits, seeds and seed coats were 559, 783 and 272 kg m−3, and the corresponding true densities were 1143, 1147 and 864 kg m−3, whereas the corresponding porosities were 48.87, 54.12, and 31.52%, respectively. The values of the static coefficient of friction and the angle of repose of fruits, seeds and seed coats of palm fruits were studied on aluminium, canvas, galvanised iron, plywood, PP knitted bag, PVC and stainless steel surfaces. As expected, seed coat has higher values of coefficient of static friction on the all surfaces than fruit and seed.

Some physical properties of palmyrah fruit were investigated in this study. The average values of major, medium, minor and geometric mean diameters of fresh whole palmyrah fruit were 11.54,10.45, 9.85 and 10.64 cm respectively at 47.34 % (w.b) moisture content whereas that of palmyrah nut were 8.59, 7.35, 4.99 and 6.79 cm respectively at 8% (w.b) moisture content. Sphericity, surface area and aspect ratio were found to be 91.94%, 359.17 cm2 and 0.90 for fruit and whereas that of nut were 79.19%, 145.16 cm2 and 0.86 respectively. The average mass of the individual palmyrah fruit and nut was 927.78 and 248.10 g whereas bulk density was 525.92 and 693.0 kg/m3 respectively. The coefficient of static friction on mild steel, glass and plywood surfaces were 0.27, 0.21 and 0.25 for palmyrah fruit and 0.36, 0.28 and 0.27 for nut respectively. The angle of repose of palmyrah fruit and nut were 30.77 and 44.03 respectively.

Engineering properties and their relationships with mass for Phule Sharbati acid lime cultivar were investigated. Relationship between physical properties of fruits and its mass will create tremendous change in the packaging industry. The mean values of engineering properties such as minor diameter, intermediate diameter, major diameter, geometric mean diameter, sphericity, aspect ratio, mass, surface area, volume and true density were found to be 42.55 mm, 41.20 mm, 40.41 mm, 0.94, 0.94, 38.17g, 49997 mm2, 33322.8 mm3 and 1 g/cc, respectively. Regression models were used to predict the effect of mass of acid lime and classified into two: 1–Single and multiple variable regressions of acid lime mass and dimensional characteristics and 2- Single variable regression for geometric mean diameter, sphericity, surface area and volume. Results indicated that mass modeling of acid lime based on minor diameter was found most appropriate in the first classification. In the second classification, the power-law model was noticed best on the basis of the geometric mean diameter, surface area and the volume.

Propagation of grasses through seeds is important in view of vigour and germination. Various grasses as Pennisetum pedicellatum Trin., Cenchrus ciliaris L., Chrysopogan fulvus have lower vigour and germination, due to which they need specific operations as defluffing, separation of true seeds, cleaning and grading by specific machines. In designing a machine for a specific use, physical properties and their behaviour with moisture play an important role. A study was conducted to assess the effect of moisture content at five levels [6.88 - 19.23 %, (d.b.)] on selected physical properties of defluffed Deenanath grass seed. The length, width, thickness, arithmetic mean diameter, and geometric mean diameter of defluffed Deenanath seed increased from 2.30 mm to 2.56 mm, 0.71 mm to 0.96 mm, 0.47 mm to 0.63 mm, 1.16 mm to 1.38 mm, and 0.90 mm to 1.15 mm, respectively, with increase in moisture content 6.88 % to 19.23 %. Bulk density, true density, and porosity decreased from 652.16 kg.m-3 to 585.78 kg.m-3, 852.63 kg.m-3 to 792.71 kg.m-3, and 25.62 % to 24.97 %, respectively, with increase in moisture content from 6.88 % to 19.23 per cent. The aspect ratio, sphericity, surface area, volume, and thousand-seed mass of the seed were in the range of 30.91 - 37.51 %, 0.39 - 0.45, 2.58 - 3.23 mm2 , 3.71 - 4.97 mm3 , and 0.480 - 0.523 g, respectively. Linear relationships with correlation coefficients higher than 0.90 were observed for the physical properties over the experimental range of moisture content.

Abstract Some physical properties of the naked oat seeds were determined as a function of moisture content ranging from 9.56 to 18.07% (wet basis, w.b.). Seed length, width, thickness, and geometric mean diameter were increased from 7.89 to 8.81 mm, 2.32 to 3.09 mm, 1.85 to 2.77 mm, and 3.24 to 4.22 mm, respectively, with the increase of moisture content. The bulk and true densities of the seed samples were decreased from 682.1 to 533.1 kg/m3 and from 1,280.6 to 1,162.8 kg/m3, respectively. The average static friction coefficients of the seeds on the surfaces of plywood, stainless steel, and polypropylene knitted bags were increased from 0.403 to 0.674, from 0.371 to 0.496, and from 0.562 to 0.765, respectively, when the moisture content of these samples were increased from 9.56 to 18.07% (w.b.). The static angle of repose varied from 24.38° to 39.17° in the moisture content range.
