Abstract: | Grain dust is a by-product produced in large quantities from grain storage and milling facilities but as of yet is treated
as waste locally and regionally. Based on the conviction that material properties determination is a necessary first step
for the efficient handling, processing, and use of materials, this work was initiated with the purpose of characterizing grain
dust in terms of its physicochemical and thermal properties.
Grain dust as a special waste material is a complex, dry, grey powder, composed mainly of grain chips, soil, whole wheat and
barley seeds, and straw. The material was found to have a bulk density of 362 kg/m3, specific heat, thermal conductivity, and gross calorific value were 1540 J/kg K, 0.27 W/m K, and 4120 kJ/kg, respectively.
Nutritional composition showed low concentrations of protein, and ether extract, and high concentrations of carbohydrates,
ash, and crude fiber. Mineral analysis showed that Ca, Fe, and K were available in significant amounts ranging from 30 to
135 ppm.
The as-received material is dry enough to be stored very safely and burned for energy production in either its loose form
or as pellets. Moreover, adjustments to the ash content and C:N ratio of the material deems it a promising candidate as an
animal feed and as a substrate for composting and biogasification. |
