“…Also, the data obtained about the hydrodynamic properties of cantaloupe can be used in the transfer, separation, and sorting through water in order to reduce processing costs and product waste. In similar studies, researchers reported that parameters such as the buoyance force and drag force can be used in modeling terminal velocity and the time length for the fruit to move up or down in the fluid (Dadashi et al, ; Jahanbakhshi et al, ; Moradi et al, ; Tarighi, Mohtasebi, Heydari, & Abasghazvini, ).…”

“…Then, to determine the dimensions and mass of the samples under experiment, a digital caliper with the precision of 0.01 mm, and a digital scale with the accuracy of 0.01 g, were used. Geometric mean diameter ( D g ), arithmetic mean diameter ( D a ) and sphericity percentage ( φ ) were calculated through relations (1)–(3) (Moradi et al, ).

D_{g} = {(italicLWT)}^{1 / 3}

D_{a} = \frac{L + W + T}{3}

φ = \frac{D_{normalg}}{L}

where L , W , and T were the length, width, and thickness of the cantaloupes, respectively. The surface area ( S ) of the samples was calculated using relation (4) in which π equals 3.14 (Shahbazi & Rahmati, ).

“…Bruising caused by a quasi‐static force is one of the most important reasons for lower quality in fresh fruits (Emadi, Kosse, & Yarlagadda, ; Junwei et al, ; Salehi, Taghizadeh‐Alisaraei, Jahanbakhshi, & Shahidi, ). Hydrodynamic transfer has been suggested as a suitable method to sort and package agricultural products and separate impurities from them (Moradi, Mousavi Khaneghah, Parvaresh, & Balanian, ).…”

Today, preserving the quality and reducing the losses of agricultural products is an important topic and has attracted the attention of many scholars in the field. This study aims at investigating the engineering properties (physical, mechanical, and hydrodynamic properties) of cantaloupe in order to manage and reduce the losses that is produced postharvest. The results show that the mean values physical properties measured for the geometric mean diameter, arithmetic mean diameter, sphericity, surface area, volume, and true density of the cantaloupes were 130.13 mm, 130.26 mm, 0.94%, 53,367.59 mm 2 , 633.30 cm 3 , and 0.83 g/cm 3 , respectively. Maximum force required for bruising and shearing cantaloupes in the investigation of their mechanical properties were 248.20 and 108.30 N. The hydrodynamic properties of cantaloupes such as the terminal velocity, the cantaloupes' rise time in the water column, the buoyance force and the drag force were obtained to be equal to 0.12 m/s, 4.10 S, 6.21 N, and 0.11 N, respectively. The results obtained through this study can be used in designing harvest machines, optimization, processing, transport, separation of impurities, and grading equipment for the purpose of reducing cantaloupe waste. Practical applicationsOf the 67 million tons of agricultural production in Iran, 20 million tons of it are turned into waste in the postharvest stage. That is the equivalent of food of 20 million people. Fruits are among the most important horticultural products that play an important role in supplying human nutrition and human health. Failure to review the engineering properties of agricultural products (physical, mechanical, and hydrodynamic properties) are the most important factors in increasing the agricultural waste at the postharvest stage. The physical properties of agricultural products are essential for the design and optimization of harvesting and postharvesting machinery, separating, transferring, grading, and drying processes. Mechanical properties can be useful in designing machinery and equipment for transportation and displacement of the product. Hydrodynamic properties can be useful for transfer, separation and grading by water in order to reduce processing costs and reduce cantaloupe waste.

The analysis of static forces is essential in the storage of agricultural products because these forces are applied in fruits, vegetables, or grains that can lead to their permanent deformation. This mechanical damage increases the product waste. Given that the potato tuber is surrounded by other tubers in the storage, then every tuber is pressurized from all sides or so-called triaxial stress. To measure the deformation of the specimens, a device was developed to conduct uniaxial and triaxial creep tests on the viscoelastic agricultural products (e.g., potatoes). Accordingly, the creep experiments were performed on potato samples for 5, 30, 60, 120, 240, 360, 420, and 480 min under the constant load of 72.5 N at 3 and 11 replications via uniaxial and triaxial tests, respectively. The results showed that in the creep test, the loading time was significant on the deformation of the specimens at the 0.05 level of probability.Triaxial test showed that the tuber deformation and strain of top layer were more than the middle and bottom layers. The results showed that the deformation of tubers under uniaxial test was more than triaxial one. K E Y W O R D Screep, potato, triaxial, uniaxial

“…According to the FAO report, about 78,000 ha of Iranian agricultural lands have been occupied by cucumber and gherkin cultivations (FAO, ). Since a large amount of harvested cucumber was used for the production of pickles, recognizing the physical and hydrodynamic properties of cucumber seems to be crucial in sketch, adjustment, and development of washing and grading machines (Moradi, Mousavi Khaneghah, Parvaresh, & Balanian, ). Furthermore, the determination of physical dimensions, volume, mass, and density of cucumber are among the most interesting points in the post‐harvesting machinery of this crop (Rao, Rizvi, Datta, & Ahmed, ).…”

The current investigation was devoted to determining some properties, such as physical dimensions, surface area, sphericity, density, stiffness, and terminal velocity of cucumber. For this purpose, different cultivars of cucumber which commonly consumed in Iran, namely, Nagin, Shahab, and Shahin were selected. Also, in order to propose a new model for the terminal velocity of cucumber, a dimensionless model was established. The obtained results showed that varieties of Shahab, Shahin, and Nagin had an average length of 163.4, 118.97, and 133.89 mm, respectively. Corresponding values for average diameter for varieties mentioned earlier were measured as 26.99, 57.811, and 27.59 mm, respectively. Moreover, the density determined from the measurement of mass and volume for Shahab, Shahin, and Nagin varieties were calculated as 956, 1042, and 990 kg m −3 , respectively, while the compressive and shear bio-yield point of them were reported as 628.38 and 74.094, 505.11 and 89.33, and 652.2 and 64.79 N, respectively. Additionally, the assessment of the dimensionless model, regarding the coefficient, mean relative deviation, and root means the square error of comparison between predicted and measured terminal velocity were 0.9, 0.15, and 0.013, respectively. Therefore, the obtained characteristics may be useful in the design of different unit operations of post-harvesting technologies. Practical applicationsMeasurement of physical properties of different common cucumber fruits can be accounted for as a useful tool to design the post-harvesting unit operations. Therefore, the proposed mathematical model for the description of the terminal velocity of cucumber could be approached in pickle production units. Also, the obtained properties are usable in hydro transport and sorting of the fruit.
