Research on rice drying and tempering has shown that high drying temperatures (up to 603C) and high moisture removal rates (up to 6 percentage points moisture content) can be used without reducing milling quality as long as sufficient tempering at a temperature above the glass transition temperature (Tg) is allowed between drying passes. Using drying air temperatures above the Tg of the rice si...

This paper presents an experimental evaluation of the first commercial scale dry-sort-redry (DSRD) strategy for drying of 2x4 Pacific coast hemlock (PCH) lumber. The DSRD strategy is a methodology designed to reduce final moisture content variability in kiln dried lumber by complementing conventional drying with radio frequency vacuum (RFV) drying technology. The strategy’s objective is to avoi...

several methods are used to decrease seed drying time and enhance the quality of dried seeds. influidization methods, good aeration occurs during the drying process. in this research, conditioned seedswith 20% d.b. moisture content were dried at 30°, 40°, 50° and 60°c using three bed conditions (fixed,minimum fluidized, fluidized). all experiments were done using a batch-type fluidized bed drye...

Background & Aim: Kelussiaodoratissima Mozaff is a valuable plant of Apiaceae family that is used as medicinal and aromatic herb. According to the importance of drying treatment on quality and quantity of essential oil, the effect of different drying methods on essential oil yield and chemical composition of Kelussia odoratissima Mozaff was examined in this research. ...

Drying is one of the most important stages of hazelnut processing and its optimization improves the quality of the final product. The quality of hazelnut is dependent on chemical and organoleptic characteristics of fruit that is affected in the drying process. In present research, samples of Gerd cultivar of hazelnut (Corylus avellana) were dried in shelled and in-shell forms using a laboratory...

A study was conducted to find out the optimum tray load and drier type for the drying of osmosed mango, guava slices and aonla segments. The osmosed slices and segments were dehydrated in a cabinet drier, low temperature drier and vacuum drier with the tray loads of 0.30, 0.35, 0.40 and 0.45 g/cm. On the basis of, correlation and regression analyses performed by using dehydration time (h), drie...

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...

Two distinct drying methods (spouted bed and spray drying) were used for production of dried extracts of Bauhinia forficata Link (Leguminosae, Caesalpinoideae). High-quality powder products in terms of physical and chemical properties were obtained. HPLC fingerprints revealed that the chromatographic profiles of flavonoid compounds present in the dried extract did not change significantly, due ...

Drying conditions affect the quality of dried soybean seeds. Therefore, an accurate description of the drying rate is required. In this study the finite element formulation and solution of diffusive moisture transfer equation was presented to improve seed drying simulation of axisymmetric bodies. The Fick’s diffusive model was solved. For experiment, thin layer soybean seed, ‘Villiamz’ variety,...
