In this research, Taguchi method application studies have been carried out to optimize the parameters affecting drying of noodles made in Çankırı region by sun, conventional oven, and microwave method. experimental study, were dried a single row thin strips 3-4 mm constant thickness form an area 100 cm2 (square plate). Variable three different methods are temperature, duration, power level. Sun...

In this work, the optimal process to improve efficiency of microwave drying rice is studied. The conditions for reducing crack rate and improving head are analyzed according principle orthogonal experiment. optimization method parameters proposed simultaneously consider two indicators, namely, rates, based on grey system theory. correlation degree analysis carried out rice. result shows that ma...

In the present study, the application of a BP neural network for prediction of the moisture content of barberry fruit (berberis vulgaris) during drying was investigated. The important parameters namely, pretreatment (heat shocking, olive oil + K2CO3 and NAT), air drying temperature (60, 70 and 80oC), air drying velocity (0.3, 0.5 and 1 m/s) and time (s) were considered as the input parameters a...

Drying characteristics of rough rice (variety of lenjan) with an initial moisture content of 25% dry basis (db) was studied in a hot air dryer assisted by infrared heating. Three arrival air temperatures (30, 40 and 50C) and four infrared radiation intensities (0, 0.2 , 0.4 and 0.6 W/cm) and three arrival air speeds (0.1, 0.15 and 0.2 m.s) were studied. Bending strength of brown rice kernel, pe...

in this study, the possibility of microwave finish drying for two types of dried grapes (natural and sultana) was investigated. the samples were washed in water bath at given temperature ranges (25 and 45 c) for 30 to 60 minutes. after dewatering the samples, they were dried using microwave (at two powers: 270 and 450 w) and hot air convective dryer (at 50 c). water gain (%), effective moistu...

this research, presents mathematical modeling of drying process of aloe vera slices with dimensions of 7×4×0.5±0.1 cm. peeled aloe vera slices with the initial moisture content of 5750% (d.b) were osmosed for 5 hours in nacl solution of 10% and temperature of 40 °c at a constant solution to fruit ratio of 5:1. osmosed and unosmosed aloe vera samples were hot air dried at 55, 70 and 85°c with di...

The energy content of wastewater is routinely assessed by chemical oxygen demand (COD) measurements that only provide an incomplete picture and the data fundament of other energy parameters remains scarce. The volumetric heat of combustion (ΔCH) of raw wastewater from a municipal wastewater treatment plant (WWTP) was assessed using oven drying method (ΔCHvol = −6.8 ± 4.3 kJ L, n = 20) and freez...

The drying of grapes is a more complex process compared to the dehydration of other agricultural materials due to the necessity of a pretreatment operation prior to drying. Grape drying to produce raisins is a very slow process, due to the peculiar structure of grape peel, that is covered by a waxy layer. Its removal has been so far carried out by using several chemical pre-treatments. However,...
