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...

The thin layer drying of pine forest residues consisting of bark, needles, leaves, and chips was experimentally conducted at air temperatures of 40, 50, 60, 70, and 80C. Physical and chemical properties of fractionated forest residues were determined to evaluate its fuel properties. The experimental data obtained from thin layer drying study were fitted with Lewis, Page, and Henderson and Pabis...

in order to improve food texture, hydrocolloids are used widely as gelling material in food systems. wild sage seed has remarkable amounts of gum (mucilage) with good functional properties. this mucilage also improves the rheological, textural and functional properties of foods. in this study the effects of different drying methods including hot air drying (40, 50, 60, 70 and 80°c), freeze dryi...

due to problems in storage, transport and price fluctuation of fresh potato, production of ready-to-use products like french fries is of particular importance.one of the important steps in product processing is pre-drying.sticks with 0.8*0.8*8 cm dimensions were prepared, blanched with hot water at 75°c for 10 minutes and dried at four different air temperatures of 50, 60, 70 and 80°c to moistu...

Spray drying is a commonly used method of drying a liquid feed through a hot gas. This study aims to obtain the empirical model of the spray drying process of full cream milk using a nozzle atomizer spray dryer, Lab-Plant SD 05 Laboratory Scale Spray Dryer. Inlet air temperature was chosen as the manipulated variable and outlet air temperature was the controlled variable. No disturbance was con...

this research was conducted for the purpose of studying the effect of caf2 content in the composition of hotmetal pretreatment flux, based on lime. it was followed in regards to the importance of fluorine amount decrease in hot metal pretreatment and steel making processes. for this purpose, lime based fluxes including 40, 30, 20 and 10 percent calcium fluoride were prepared and hot metal pretr...

In this study, air-drying experiments in thin layers of mulberry grown in Istanbul, Turkey, were conducted. The effect of ethyl oleate solution on drying time of mulberry samples was investigated in a pilot air-dryer. When ethyl oleate was used as pretreatment solution, the drying time of samples was decreased. Drying curves were obtained using the Page model. The effective diffusivity varied f...

In this study, the drying characteristics and quality properties of electrical (ET) ultrasound (US) pre-treated kiwi fruit slices were investigated. Electrical pretreatments carried out on parameters 100 V- 40 sec. 35 kHz-30 min respectively. After pretreatments, dehydrated using a convective dryer at 50°C 1.5 m/s air flow rate. The effects these rate (the total phenolic content, vitamin C, pec...

the aim of this study was investigation of the effects of pretreatments (hot water blanching and chemical treatments) by hot air and sun drying methods on mass transfer kinetics during red chili pepper rehydration phenomenon. for these purposes fick's second law and peleg model were applied for modeling of red chili pepper rehydration phenomenon. the results revealed that, peleg model coul...
