date palm (phoenix dactylifera l.) with its delicious and nutritious bearing fruit (dates) is an important agricultural core in iran. to extend the shelf life of date palm fruit, some such methods of preservation as drying are suggested and drying influences physicochemical and quality characteristics of products, thus modeling of drying kinetics is one of the tools for process control. in this...

Drought reduces the carbon (C) assimilation of trees and decouples aboveground from belowground carbon fluxes, but little is known about the response of drought-stressed trees to rewetting. This study aims to assess dynamics and patterns of C allocation in beech saplings under dry and rewetted soil conditions. In October 2010, 5-year-old beech saplings from a forest site were transplanted into ...

Leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. Determining drying characteristics of leather is vitally important so as to optimize the drying stage. This paper describes an analytical way for determination of the drying characteristics of leather. The model presented, is based on fundamental heat and mass tra...

Peat swamp forest have a high economic value and are potential for agricultural development. However, peatlad fragile ecosystems because they easily damaged difficult to restore. The main problem of all peat soil types is their irreversible drying. In this condition the easy burning, unable store water, if groundwater far from surface, plants will be stressed lack water. Therefore support susta...

Although Mediterranean wetlands are characterized by extreme natural water level fluctuations in response to irregular precipitation patterns, global climate change is expected amplify this pattern shortening seasons and increasing the incidence of summer droughts area. As a consequence, part lake sediment will be exposed air-drying dry years when table becomes low. This periodic exposure dry/w...

the present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140ºc and airflow rates of 1.8, 3.1 and 4.5 m s-1. six mathematical models for describing the fluidized bed drying behavior were investigated. the value of the drying rate coefficient (k) increased with inc...

the canola drying process was investigated using three laboratory scale dryers connected to a computer which continuously recorded the drying processes of each unit. a completely randomized design (crd) with three replications was used for the statistical analysis. the effect of temperature (40°, 50°, 60°c) and air velocity (1, 2 m/s) on the drying kinetics of a monolayer were studied. the effe...
