The rising demand for bioethanol, the most common alternative to petroleum-derived fuel used worldwide, has encouraged a feedstock shift to non-food crops to reduce the competition for resources between food and energy production. Sweet sorghum has become one of the most promising non-food energy crops because of its high output and strong adaptive ability. However, the means by which sweet sor...

The aim of this research was to evaluate four different cacao (Theobroma cacao L.) fermentation conditions and their effect on fermented bean quality, in order to be able to recommend the most suitable condition to producers in the municipality of Huimanguillo, Tabasco, Mexico. Fermentations were carried out in square wooden boxes with capacity for 1000, 300, and 100 kg of fresh beans, as well ...

Coating of particulate solids by a thin film layer is of interest in many industrial applications such as seed and tablet coating. In seed processing, seeds are commonly coated with a protective coating layer consisting of fertilisers and crop protection products. Rotary drum batch coaters are typically used for this purpose. The coater consists of a cylindrical vessel with a rotating spray dis...

High temperature metallurgical slag (temperature, >1450?C) and high moisture sludge (moisture content, >80 wt.%) are common wastes with huge outputs. Many problems, such as cost, low level of harmlessness, efficiency, encountered in current treatment methods. If these can be recycled, they valuable secondary resources. Therefore, using the drum apparatuses to treat two kinds is proposed. ...

In the favourable current context for the development of biological treatment of Residual Municipal Solid Wastes (RMSW), the Rotary Drum Reactor (RDR) is a pre-treatment tool increasingly used in construction or rehabilitation facilities. RDR allows a better preparation of waste before mechanical sorting and biological treatment. This preparation process, recognized by profession’s actors, is h...

Experiments on granule transport and the mean residence time in a rotary horizontal drum with inclined flights showed that the granules can be transported steadily. A model for granule transport based on the analysis of granule motion and other studies on inclined drums was developed to calculate the mean residence time of the granules, and verification experiments under different conditions we...
