drying properties of high moisture potato slices with initial moisture content of about 4.06 (db) under thin layer fixed, semi fluidized and fluidized bed conditions were studied. drying air temperatures of 40, 50, 60 and 70°c were applied in experiments using a laboratory fluidized bed convective dryer. in order to predict the drying behavior of potato slices, seven thin layer drying models we...

The drying process of traditional Chinese medicine Rosa laevigata Michx was investigated in a laboratory scale dryer. Drying experiments were conducted at five temperatures of 40 ̊C, 50 ̊C, 60 ̊C, 70 ̊C and 80 ̊C. The experimental data were fitted to ten different thin layer drying models to select a suitable model for describing the drying process of Rosa laevigata Michx fruits. The results showed ...

the main purpose of present paper is the modeling of onion drying process and investigation of experimental data of onion drying obtained with using a hot air dryer. therefore some empirical and regression models have been considered to fit experimental data. the investigation of the experimental data shows the onion drying happens only in falling rate zone. the experimental data have been fitt...

The effect of air temperature, air velocity, and sample shapes (circle and square with the same cross-sectional area) on kinetic drying of potato slices in a tunnel dryer was investigated experimentally and a suitable drying model was developed. The experiments of drying of potato slices were conducted at an air temperature of 45-70°C with an air velocity 1.60 and 1.81 m sec(-1). Results showed...

Midilli’nin Osmanlı egemenliğine girmesiyle buradaki iskeleler önemli görevler üstlendiler. Adadan elde edilen zeytinyağı ve sabun, İstanbul sarayın tercihi, ada iskeleleri ise iç dış ticaretinin bir noktası oldu. Bunun sebebi adanın konumuydu bu önem sonraki yüzyıllarda da artarak devam etti. 18. yüzyıla gelindiğinde, uluslararası ticaret yolları aktörlerinin değişiminin de etkisiyle etrafında...

The effects of pretreatment solution (dipping in boiling water, salty boiling water, ethil oleat) were studied on drying kinetic of sour cherry. The thin-layer drying of sour cherries were carried out at three air temperatures of 50, 60 and 70°C and airflow velocity of 1 m/s. The experimental data were fitted to several thin-layer drying models such as Newton, Henderson and Pabis, Page, Logarit...

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...

this paper peresents a mathematical model for the thin layer drying of the viliamz cultivar of soybean. the thin layer drying behaviour of soybean was experimentally investigated and the mathematical modelling performed by using thin layer drying models provided in the literature. experiments were conducted at inlet drying air temperatures of 30, 40, 50, 60 and 70ºc and at a fixed drying air ve...

Abstract The study describes the mathematical calculation of pumpkin drying process. In order to check data obtained for different temperatures in experiment (45, 55 and 65 °C) choose most appropriate model, comparisons were made with models. For this purpose 5 experimental theoretical models used, which are widely used processes (Lewis, Henderson Pabis, two terms, Wang Singh, Midilli). Statist...
