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...

Title of Document: AN EXPERIMENTAL ANALYSIS OF FIREFIGHTER PROTECTIVE CLOTHING: THE INFLUENCES OF MOISTURE AND A THERMALLY ACTIVATED EXPANDING AIR-GAP. James Patrick White, Master of Science, 2012 Directed By: Professor, Marino di Marzo, Department of Fire Protection Engineering Thermally protective clothing garments are necessary pieces of equipment that ensure the life safety of firefighters....

Thin layer drying of Russian olive (Elaeagnusan gastifolial L.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. The selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°C. Increased air temperature...

Monitoring of a passively-aerated plastic-wrapped mortality composting system designed for emergency disposal of diseased swine highlighted the importance of the physical characteristics of materials used to envelop the carcasses. Inadequate moisture was a problem when using envelope materials such as ground cornstalks or straw having low density and high air-filled porosity. High O2 concentrat...

This intervention study was designed to show the effects of the renovation of moisture and mold damaged school building on the schoolchildren’s health and exposure. Microbial sampling from indoor air of the school and a health questionnaire study were performed before and after renovation. The results were compared to those from non-damaged reference school. The effect of a thorough renovation ...

in this research, the bioinsising impact of two wood decay fungi (pysisporinus vitreus and xylaria longipes) on radial air permeability and moisture diffusion coefficient of spruce wood (picea abies) was investigated. fungal cultivation was performed in an incubator at 25 °c and 85% relative humidity for 15, 30 and 45 days. results showed that the permeability, moisture diffusion and mass loss ...

a fully instrumented air conditioning laboratory unit capable of controlling drying air temperature and humidity integrated with an instantaneous weighing thin layer drying system was used to investigate the thin layer drying behavior and desorption equilibrium moisture content of canola (brassica napus l.). to this aim, freshly harvested canola samples with moisture content of about 12±0.5% (d...

Spray drying is a common drying technique in food industries to convert liquid to powder form. A good understanding on the dynamic behavior of the process is important to ensure proper control. The aim of this study is to develop empirical models for spray drying of whole milk powder and orange juice powder. A preliminary study on the effect of several inputs such as inlet air temperature, feed...

Milled rice kernels have been shown to rapidly fissure and eventually break when exposed to certain air conditions (Stermer 1968, Kunze and Hall 1967, Siebenmorgen et al 1998). Milled kernels rapidly gain or lose moisture from the environment depending on the air temperature and relative humidity (RH) of the surrounding air, as well as the moisture content (MC) of the kernels (Kunze and Choudha...

With global food demand expected to increase by 100% in the next 50 yr, urgency to combine comprehensive strategies for sustainable, efficacious, and environmentally sensible agronomic practices has never been greater. One effort for US meat bird management is to reduce NH(3) volatilization from litter to create a better growing environment for the birds, improve production efficiency, retain N...
