| Three voltage gradients (8.38, 10.83, and 13.33 V cm-1) and three weight loss percentages (10, 20, and 30 percent) were examined; also the system performance coefficient, input current, heating process duration, power consumption and electrical conductivity investigated. The response surface method was also used for modeling s and optimization. For the response surface method, weight loss percentage and voltage gradient were selected as independent variables; and factors system performance coefficient, heating process duration, input current, power consumption and electrical conductivity were selected as responses. According to results, all obtained models were significant for responses factors, but the voltage gradient and weight loss percentage were... |

| In this research, energy and exergy loss were analyzed in the laboratory for the drying of eggplant using a fluidized bed dryer. The drying experiment was conducted at inlet temperatures of 40, 50, and 60 and air velocities of 3, 5, and 7 m/s using samples with diameters of 5, 10, and 13 mm and a height of 1 cm. The effects of temperature, velocity of drying air, and sample size on energy consumption and exergy losses were investigated. The results showed that the minimum energy consumption and exergy losses occurred at a diameter of 13 mm, velocity of 3 m/s, and temperature of 40. Meanwhile, the maximum energy consumption and exergy losses occurred at diameter of 5 mm, velocity of 7 m/s and temperature of 60;. Generally, the results demonstrated that... |

| Nowadays, dielectric materials, as one of the nondestructive methods, have drawn the researchers’ attention to their diverse array of advantages to the other methods. Before loading and storage, 120 pears were examined under CT-Scan and 81 pears with zero bruise were selected followed by subjecting them to quasi-static and dynamic loading and a 10 day storage period was chosen to investigate the bruise levels and their relationships with dielectric constant. At the end of the storage period, the fruits were measured in their dielectric constant after their bruise levels were determined in CT-Scans. The measurements were undertaken in capacitor plate distances of 8, 11 and 14 cm for input voltages of 6, 10 and 14 V and input voltage frequencies of 20, 60... |

| This study was conducted considering the high importance of persimmon's chemical properties and the effect of different factors on its variations during storage and maintaining period. This study attempted to investigate some cases such as the effect of compressive loading parameters at 2 levels of 150 N and 250 N, three types of foam container packaging with polyolefin film, polyethylene terephthalate, and ordinary box and four types of putrescine polyamine coating with concentrations of 1 mM and 2 mM, distilled water and uncoated state, the chemical properties of persimmon fruit including the number of antioxidants, total phenol, flavonoids, vitamin C, pH, acidity and dissolved solids. The results showed that the highest content of total phenol and... |
