Evaluation of Drying Methods With Respect to Drying Kinetics and Mineral Contents of Dill and Parsley
Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (50oC) drying methods. Oven drying decreased the drying time approximately 50% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the su...
متن کاملComparison 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 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 کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Comparative study of three drying methods: freeze, hot air- assisted freeze and infrared-assisted freeze modes
The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...
