BACKGROUND Drying of nectarine slices was performed to determine the thermal and physical properties in order to reduce product deterioration due to chemical reactions, facilitate storage and lower transportation costs. Because nectarine slices are sensitive to heat with long drying period, the selection of a suitable drying approach is a challenging task. Infrared-vacuum drying can be used as ...

one of the new techniques applied in the drying process of food stuffs that can increase the drying rate, enhanced the product quality, and while decresing the costs of processing is an application of infrared radiational energy. in this study the thin layer drying process of button mushroom was modeled through an infrared applied drying method. drying experiments with sliced samples of button ...

in this study, green pepper was dried by a laboratory scale microwave-convective dryer. the effects of microwave power on drying rate, effective moisture diffusivity, and energy consumption of green pepper were studied at four different microwave powers of 180, 360, 540, and 720w. the drying data were fitted to the four thin-layer drying models. the moisture reduction of the green pepper sample...

in this paper the energy and exergy analyses in chamber drying process of thin layer drying of tomato in a forced solar drying was investigated. the experiments were carried out with two thicknesses of 5 and 7 and two airflows 0.5 m.s-1 and 1 m.s-1. during the experimental process, ambient temperature was between 22 and 36 , air relative humidity between was 14 and 50, and solar radiation range...

Preliminary notes A laboratory laser beam drying method for corn grain kernels is presented and the corresponding energy transfer is analysed. The proposed drying method enables fast and efficient decrease in grain humidity while preserving grain sprouting. Laser beam was directed to the thin grain layer with powers of 10 kW/m and 20 kW/m. Grains were illuminated from one side during a period o...

Drying conditions affect the quality of dried soybean seeds. Therefore, an accurate description of the drying rate is required. In this study the finite element formulation and solution of diffusive moisture transfer equation was presented to improve seed drying simulation of axisymmetric bodies. The Fick’s diffusive model was solved. For experiment, thin layer soybean seed, ‘Villiamz’ variety,...

Drying kinetics of Cape gooseberry was studied and modeled during processing at four temperatures (60, 70, 80 and 90C). Desorption isotherm was obtained at 40C giving a monolayer moisture content of 0.086 g water/g d.m. Experimental drying curves showed that drying process took place only in the falling rate period. Several thin-layer drying models available in the literature were evaluated bas...

in this study thin layer drying of corn in a convective dryer was investigated at air temperatures of 50, 60 and 70ºc and air flow rates of 1, 1.4 and 1.8 kg min-1. experiments were performed in completely randomized design (crd). the effect of air temperature and flow rate on drying time, drying rate, effective diffusivity coefficient and activation energy were studied. results showed that the...
