• Abstract

  A considerable amount of dried herbs for supplying of pharmaceutical and food industries in Brazil is concentrated in local producers, who handle and process the materials based mainly on empirical techniques. Low quality of dried products, as well as irregular and seasonal production, are recurrent complaints of industry and final consumers. The crescent demand for fresh herbs and thei…

• Abstract

  The use of biomass is considered an excellent alternative for sustainable power production plants, for example, in process such as pyrolisis, gasification and combustion. Nevertheless, a common problem in operation of thermoelectric reactors is to ensure a stable, efficient and economic feeding of the particulate materials into the reactor. The solid feeding can be particularly limiting i…

• Abstract

  Convective drying of phytotherapic leaves involves heat and mass transfer in packed-beds of deformable material, since the leaves shrink significantly when the moisture is removed. Therefore, the packing structure changes over time, and the transfer properties alter as well. An additional drawback in the analysis of this process is the challenge to obtain reproducible packings to investig…

• Abstract

  Biomass residues are generated in huge amounts in processing and are often used as a feedstock in industrial-scale energy cogeneration processes. In spite of that, a common problem in the operation of thermoelectric reactors is to ensure a stable, efficient and low-cost feeding of the particulate materials into the reactor. The solids feeding can be particularly limiting when using biomas…
