摘要

Sugarbeet is one of the main sugar crops in the world. In the search for sustainability and economic value, the complete utilization of the crop is necessary. In addition to sugar production, sugarbeets can provide many value-added by-products for animal feeding. One of major byproducts in sugarbeet plants is sugar beet pulp that has a fairly high moisture content of 75-85%, which makes sugarbeet pulp storage a challenge, drying and palletization are the consequence important processes for further appropriate packaging and exportation. Sometimes the risk of pellets marketing internationally affects pellets handling, especially the storage for a while until marketing circumferences improved, even for local consumption or exportation. The need for a suitable technology is emerged for that reason; moreover this by-product has a nutritious value close to other traditional feeding crops. In Egypt nowadays the silos are considered to be a vital facility for crops storage for international trading. So this paper aims to design a proper silo for sugarbeet pulp storage. Proper silo is depending basically on the strength and flow properties of sugarbeet pulp pellets under operat- ing conditions. After studying the engineering characteristics of sugarbeet pulp pellets, yield locus was implemented for determining the flow properties according to Jenike principals for proper silo design and examining the discharging behavior visually; Analytical and experimental procedures have been used to determine the values of pressures inside silos and for predicting the characteristics of the flow pattern. A model silo for assaying pressure in this silo basically consists of cylindrical silo equipped with load cells to measure pressure and variable-frequency drives connected to each of the electric motors driving the filling and discharge screw conveyors, in order to investigate the effect on pressure of the speed at which the silo is filled or discharged. These runs of experiments were conducted at the Department of Agricultural Engineering, Kafrelsheikh University during spring and summer seasons of the year 2015. As a result of this investigation, the flow index of sugar beet pulp pellets was 14.5 and was classified as a cohesive and free flowing material. The silo wall-pellets friction angle was of 20°. Pellets discharging behavior represents mass flow pattern at each height at half angles of 10° and 20° and discharging opening dimensions of 0.17 and 0.13 m. Stress distribution analysis shows the highest values of bending moment at hopper section of 10.2N/mm~2 and tensile stress of 2.014N/mm~2 at silo section.
