drying of agricultural products is a sophisticated process with high energy consumption. energy needed for sustainable development, is one of the biggest challenges facing humanity. the performance of a heat recovery assisted solar dryer was evaluated in this study. drying time, collector efficiency, energy consumption, solar fraction and energy recovery fraction were investigated at different ...

Coffee (Coffea arabica L.) seeds are sensitive to desiccation and oxidative stress during drying processes. We investigated the effect of drying and moisture levels on germination-related gene expressions associated with enzymatic systems that prevent oxidative stress in coffee seeds. Coffee seeds collected at physiological maturity were subjected to slow and quick drying to 40, 30, 20, and 12%...

Microwave drying technology has the potential for large production time and energy cost savings versus traditional vacuum drying methods for active pharmaceutical ingredient (API) applications. One of the most critical parameters in the drying process is the determination of the end point, usually at a specified moisture content. On-line mass spectrometry (MS) was used as a tool to monitor micr...

This in vitro study evaluated the effect of air-drying time on degree of solvent evaporation (DE), dentin microtensile bond strength (µTBS), and degree of conversion (DC) of 5 adhesive systems: Adper Single Bond 2, XP Bond, Prime & Bond 2.1, OptiBond Solo, and Adper Easy One. For DE testing, 20 µL of each material was submitted to measurements in a digital balance after an air stream of 3, 5, 1...

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 Drying of nectarine slices was performed to determine the thermal and physical properties in order to reduce product deterioration due to chemical reactions, facilitate storage and lower transportation costs. Because nectarine slices are sensitive to heat with long drying period, the selection of a suitable drying approach is a challenging task. Infrared-vacuum drying can be used as ...

ABSTRACT- To evaluate effects of different soil moisture conditions namely, phosphorus (P) and zinc (Zn) application, on extractable Zn and Fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. The first experiment was performed with the following factors; incubation time at four leve...

The purpose of this study was to determine the stability quality and shelf life dried shredded African catfish (Clarias gariepinus). method used in quantitative research using an experimental a completely randomized design with three different drying treatments. Gariepinus) color varying methods drying, giving panelist scores ranging from 2.36 4.4; organoleptic value floss ranged 2.88 4.16; pan...

Thermal modification is a well-known process to change the dimensional stability, hygroscopicity, and biological resistance of wood due to chemical modifications of wood cell components. In this study, we reviewed several characteristics of heat-modified solid wood and wood-based panels under various temperatures, durations and pressure. Thermal compressing treatment could affect drying speed, ...

Gentle in-store drying of popping corn may reduce the risk of stress fissures being generated, an effect which reduces popcorn expansion volume. In order to allow optimisation studies of in-store drying to be conducted, thermophysical properties of two current Australian popping corn varieties were measured in the range 30-50°C, at moisture contents from 12% to 20% wb. Models were developed for...
