Pilot composting experiments of swine manure with corncob were conducted to evaluate the performance of the aerated static bin composting system. Effects of temperature control (60 and 70 degrees C) and moisture content (70% and 80%) were monitored on the composting by measuring physical and chemical indexes. The results showed that (1) the composting system could destroy pathogens, converted n...

Damask rose (scientific name: Rosa Damascene) belongs to Rosaceae families and is valuable in medicine. In this study, the influence of air temperature and velocity are investigated on hot air dryer of the rose petals. Artificial drying of the agricultural products is one of the most common maintenance procedures. Suitable drying methods reduce the waste and damage during the storage and save t...

In this research, the breakage susceptibility of two classes of lentil (green and red) was evaluated as affected by impact energy and seed moisture content. The experiments were conducted at impact energies of 0.1, 0.2 and 0.3 J, and moisture contents of 10, 12.5, 15, 17.5, 20 and 25% (wet basis). Results showed that red lentil seeds had more breakage than green seeds and the difference in brea...

In this study, the effect of extrusion process parameters of a locally developed extruder on the moisture loss of extrudates of the flour and starch of maize and cassava which are grown in Nigeria in large quantity were characterized. These were compared with those of wheat flour which is commonly used for the production of alimentary paste. The parameters considered include feed moisture (30, ...

In this study, the application of a response surface methodology (RSM) to optimize the microencapsulation of vanillin as a nutraceutical was studied. Soy protein isolate and maltodextrin were used as a wall material. Microencapsulate of vanillin using spray drying with maltodextrin solutions at different concentration (5–15% wt), vanillin concentrations (0.1–0.4 %wt) and inlet temperature (180–...

an aerobic, meophilic and lipolitic bacillus.sp bacterium (lipase activity 40 u/ml) was isolated from the olive extract. this isolate was identified based on morphological and biochemical characterization and 16s rrna gene sequence. effect of the solid substrate (pomegranate seed ground, grape seed ground and coriander seed ground as a solid substrate), the substrate particle size, moisture con...

The proper use of polymers as conditioners is a critical aspect of dewatering processes. In this study, we investigate their physical properties, i.e. size, density and fractal dimension and correlate them with their dewatering characteristics (bound water content, CST and SRF) on alum sludge with cationic polymer conditioning. Using CST measurement to determine the optimum polymer dose may lea...

Beef cattle feedlots face serious environmental challenges associated with manure management, including greenhouse gas, odor, NH3, and dust emissions. Conditions affecting emissions are poorly characterized, but likely relate to the variability of feedlot surface moisture and manure contents, which affect microbial processes. Odor compounds, greenhouse gases, nitrogen losses, and dust potential...
