In this study, the effects of the storage duration of coffee cherries after harvest before putting out for sun drying on the kinetics of drying, fungi development and the variation of physicochemical content were evaluated. The results showed that the longer coffee cherries were stored after harvest before putting out for sun drying, the quicker they dried. Indeed, the drying durations were 19,...

Th e drying characteristics of “Granny Smith” apples were analysed using a tunnel drier at diff erent temperatures and diff erent pre-treatments. „Granny Smith“ apples were cut into rectangle-shaped samples 20x20x5 mm in size. Th e drying temperatures for non-treated samples varied from 50oC to 80oC at airfl ow velocity of 2.8 m s-1. Prior to drying at 60oC, the samples were pretreated either t...

HIGHLIGHTS Drying kinetics of shrimp shell and crab exoskeleton were obtained experimentally The Page Midilli models showed the best fitting results to simulate experimental data Third-order for both materials using stepwise fit method ANNs performance describe drying curves Modeling process can be simulated successfully by multivariable approaches.

Drying has been widely studied as a necessary process in biomass utilization. The steam diffusion law plays an important role drying kinetics. kinetics of single particle using Fick’s second was this paper. A parabolic relationship appeared between the critical moisture content and temperature. decreased with increase temperature initial content. had significant effect on effective diffusivity ...
