To establish the most convenient and effective method to dry tangerine peels, different methods (sun drying, hot-air drying, freeze drying, vacuum drying, and medium- and short-wave infrared drying) were exploited. Our results indicated that medium- and short-wave infrared drying was the best method to preserve nutraceutical components; for example, vitamin C was raised to 6.77 mg/g (D.W.) from...

Conservation of agricultural crops and minimization of grain losses is challenging issue in the present scenario. Effective use of thermal energy for drying of paddy and other cereals for maintaining proper quality is the quality drying process. Natural convection grain dryer is quite suitable for under developed and developing countries like India where rural electrification and advanced dryin...

the drying behavior and characteristics of date paste were studied at temperatures of 60, 70, and 80ºc as thin layer with sample thicknesses of 1, 1.5, and 2 cm in a laboratory scale vacuum chamber. modeling of drying kinetics of date paste was investigated based on the specific temperatures and sample thicknesses. the experimental moisture loss data were fitted to eight thin layer drying model...

Abstract—There was a scenario present day that drying of fresh fruits and vegetables by indirect solar drying by using mechanical device; hence, an effort was made to develop a small scale solar tunnel dryer (STD). Drying of spinach is carried out to analyze the performance of the dryer and to study its drying characteristics. To evaluate the performance of dryer the independent variables were ...

in this research the drying of four kinds of vegetables was investigated in a vacuum dryer. the effect of temperature on drying rate of samples at various temperatures (30, 35 and 45 °c) was studied. six thin-layer drying models were fitted to drying data and suitable model was selected from them. then effective moisture diffusivity and activation energy of samples were calculated. the diffusio...

the objective of this study was to investigate the drying kinetics of oyster mushroom, pleurotus ostreatus mushrooms were dried using a cabinet-type convective dryer. air temperatures of 50, 60 and 70 oc were used for the drying experiments. the experimental drying data were fitted to different theoretical models to predict the drying kinetics. nonlinear regression analysis was performed to rel...

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...

background : agaricus blazei mushrooms are one of the most important edible and therapeutic mushrooms, and they contain minerals, vitamins, and amino acids essential for the human body. this mushroom is used raw, dried, and in the form of pharmaceutical products. one of the most important processes after harvesting is drying in order to enhance the quality and the length of maintenance of the p...

Characteristics of microwave drying of wood strands with different initial moisture contents and geometries were investigated using a commercial 10 small microwave oven under different power inputs. Temperature and moisture changes along with the drying efficiency were examined at different drying scenar­ ios. Extractives were analyzed using gas chromatography=mass spectrometry (GC=MS). The res...
