Comparison of Three Methods of Estimating the Effective Diffusivity of Moisture in Meat from Drying Data
S The diffusivity of water in meat was experimentally determined using a drying technique. Three different mathematical methods were used to determine the diffusivity from the drying data. The first assumes constant diffusivity, volume, temperature and surface moisture concentration. The second assumes a convective boundary condition. The last also takes into account shrinkage. Important differ...
متن کاملEstimation of the Moisture Diffusivity and Activation Energy in Thin Layer Drying of Ginger Slices
In the present work, the effective moisture diffusivity and activation energy were calculated using an infinite series solution of Fick’s diffusion equation. The results showed that increasing drying temperature accelerated the drying process. All drying experiments had only falling rate period. The average effective moisture diffusivity values varied from 2.807x10 to 6.977x10m s over the tempe...
متن کاملEstimation of Moisture in Transformer Insulation Using Dielectric Frequency Response Analysis by Heuristic Algorithms
Transformers are one of the most valuable assets of power systems. Maintenance and condition assessment of transformers has become one of the concerns of researchers due to huge number of transformers has been approached to the end of their lifetimes. Transformer’s lifetime depends on the life of its insulation and the insulation’s life is strongly influenced by its moisture attraction as well....
متن کاملEffect of Air Velocity and Temperature on Energy and Effective Moisture Diffusivity for Russian Olive (Elaeagnusan gastifolial L.) in Thin-Layer Drying
Thin layer drying of Russian olive (Elaeagnusan gastifolial L.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. The selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°C. Increased air temperature...
متن کاملstudy on drying behavior, effective moisture diffusivity and activation energy of hot air-drying of different tarkhineh formulations
the effects of a couple of factors (cooking period of wheat: 0, 1 and 3.5 h and temperature of drying 70, 80 and 90 ْc) on drying behavior of tarkhineh during hot-air drying has been investigated. tarkhineh pill samples with 8 cm diameter and 11 mm thickness were dried to 0.64(d.b). results showed that cooking of wheat led to higher water absorption of tarkhineh dough, while increased drying rat...
