This paper presents a scale model of grain storage tower, i.e. a silo for drying and airing cereal grains. The scale model consists of a 2.50 m wide x 2.10 m long plant with all control and monitor capacities provided by Micro Web Servers. An application running on the Micro Web Servers enables storing all parameters in a data basis for later analysis, preferably done remotely. The implemented ...

Earlier studies of silo pressures generally suggested that wall pressures would be symmetrical if the filling and discharging were both symmetrical. However more careful measurements showed that wall pressures can vary significantly around the circumference and can be unsymmetrical even in symmetrical silos which appear to be symmetrically filled and discharged. The loss of symmetry may be trac...

Experiments and computational simulations are carried out to study the behavior of a granular column in a silo whose walls are able to vibrate horizontally. The column is brought to a steady fluidized state and it behaves similar to a hydrostatic system. We study the dynamics of the granular discharge through openings at the bottom of the silo in order to search for a Torricelli-like behavior. ...

Three workers died from carbon dioxide poisoning in a partly underground silo which had been almost completely emptied of green forage. Two died at once, the third after five days without regaining consciousness. Several similar cases are reported in the literature. Wrede (1936) described a case of carbon dioxide poisoning which occurred in a cellar through the escape of gas from a beer barrel....

The study evaluated the performance of polypropylene bag (PP), polyethylene drum (PD), silo tank (PST), and super grain (SGB) on preserving maize quality. trials were conducted on-station on-farm. Insect density, damage, weight loss, moisture content determined monthly for six months trials. For on-farm, insect density damage assessed every two eight months, acceptability test was performed aft...

The dusty challenge Obtaining reliable level measurement has traditionally been a severe challenge because cement production is such a dusty process. During homogenization, for example, silos are continuously filled and emptied, and the component materials are constantly aerated to ensure good mixing. This creates a tremendous amount of dust that makes it difficult to obtain reliable readings w...

For many years educators have operated in “silo mode” providing the benefits of depth and rigor, but often short-changing context and applicability. This is particularly important when addressing the current Reality TV Generation that demands immediate relevance. In stark contrast to the silo approach, Informatics brings together technology, information, and people. Scientific principles of ana...
