study 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...
متن کاملeffective moisture diffusivity modeling of sweet lemon slices
thin layer drying behavior of sweet lemon slice was experimentally investigated in a convective type dryer and the mathematical modeling performed, using thin layer drying models given in literature. drying experiments were conducted at inlet drying air temperatures of 40, 50, 60, 70 and 80 ?c; two slice thicknesses of 3 and 6 mm, and, at one drying air velocity of 0.5 m/s with three replicatio...
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 کاملKinetic Models for Colour Changes in Kiwifruit Slices During Hot Air Drying
The colour changes that occur in kiwifruit during the dry process were experimentally studied in order to determine the magnitudes of the parameters for a corresponding colour change model. The drying experiments were carried out under five air temperatures of 40, 50, 60, 70 and 80°C, air velocity of 1.0 m/s and kiwifruit slice thickness of 4 mm. The colour parameters for the colour change of t...
متن کاملسینتیک افت رطوبت و مقایسه کیفیت ورقه‌های گوجه‌فرنگی در مرحله خشک‌شدن با سه روش: خشک‌کردن خورشیدی، آفتابی سنتی و هوای خشک
Sun drying is a well-known food preservation technique that reduces the moisture contents of agricultural products. Shrinkage, rehydration ability and color of food materials during air drying adversely affect the quality of the dried products. Since all fresh tomatoes can not be consumed at the time of harvest, preservation provides a larger market, allowing consumers to buy the preserved toma...
