21st International Drying Symposium
Permanent URI for this collection
Similarly to its previous biennial IDS conferences, the objective of IDS2018 is to provide the most advanced and comprehensive global forum for disseminating results and data in research, development and applications in drying/dewatering sciences and technologies.
This Symposium will be held on the main campus of the Universitat Politècnica de València, deemed among the best Spanish technical universities and ranked among the best 100 Institutions in the world in the field of Agriculture and Forestry. The conference aims to bring together world-renowned researchers and engineers, both from academia and industry, in this university environment. An Awards program will also form part of the event for the international drying community.

Recent Submissions
- PublicationSimultaneous wetting and drying; fluid bed granulation and tablet film coating(Editorial Universitat Politècnica de València, 2018-09-07) Kemp, Ian; van Millingen, Alex; Khaled, Houda; Iler, Lewis[EN] Simultaneous wetting and drying occur in processes such as fluid bed (top spray) granulation, Wurster coating and tablet film coating. This gives control challenges, as the spraying and evaporation processes must be carefully balanced and the operating window is significantly narrower than for standalone drying processes. Significant recent advances in modelling have led to effective scale-up and operational strategies. Factors such as flow cessation during filter bag shaking can have a major effect. A design space can be predicted which is often non-orthogonal, and pharmaceutical regulatory authorities have accepted filing submissions using a design space justified by mechanistic modelling.
- PublicationInfluence of drying temperature and ultrasound application in some quality properties of apple skin(Editorial Universitat Politècnica de València, 2018-09-07) Martins, Matheus; Cortés, Edgar; Simal, Susana; Mulet Pons, Antonio; Pérez-Muelas Picón, Mª Nieves; Cárcel Carrión, Juan Andrés; Dpto. de Tecnología de Alimentos; Instituto Universitario de Ingeniería de Alimentos (FoodUPV); Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Grupo de Análisis y Simulación de Procesos Agroalimentarios; Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria; Ministerio de Economía y Competitividad[EN] The great amount of waste produced by the food industry can be an interesting source of bioactive compounds. To this end, convective drying is one of the most extended method to stabilize the industrial by-products. However, drying conditions can affect not only drying kinetics but also the bioactivy of some compounds. Apple skin constitutes one of the main by-product generated in apple juice or cider production. It contains important amounts of functional compounds such as polyphenols or vitamin C whose extraction can be interesting. The main aim of this work was to determine the influence of drying conditions, temperature and application of ultrasound, in some quality parameters of dried apple skin. For this purpose, apple skin samples were dried at different temperatures (-10, 30, 50 and 70 ºC) and with (20.5 kW/m3) or without application of ultrasound. Color, total phenolic content, antioxidant activity and vitamin C was measured in fresh and dried samples. The increase of drying temperature and the ultrasound sligthly reduced the antioxidant properties of samples while no influence in sample color was observed.
- PublicationBread preservation with use of edible packaging(Editorial Universitat Politècnica de València, 2018-09-07) Silva, Viviane; Fakhouri, Farayde; Arias, Luna; Aguiar, Rosa; Oliveira, Rafael[EN] We live in a world that usually use plastic bags either to go shopping or to pack the snack for a short trip. However, packaging makes life easier and serves as protection for products such as food. Bread is a common food product that needs packaging in order to be protected at storage and transportation. Therefore, with aim of reducing petroleum derived packagin g consumption it was developed an edible film from potato starch to packeg bread and some quality characteristics like water content, firmness and weight loss were evaluated, showing that edible film can be used as a packaging.
- PublicationDrying of algae by various drying methods(Editorial Universitat Politècnica de València, 2018-09-07) Bheda, Bhaumik; Shinde, Manoj; Ghadge, Rajaram; Thorat, Bhaskar[EN] Algae drying was carried out using Vacuum Tray Dryer and an Innovative Solar Conduction Dryer. Algae was dried in a Vacuum Tray Dryer at 60°C under varied pressure conditions and makes use of specially designed double condenser system. The open sun drying and solar conduction dryer (SCD) was also used for algae drying. Comparison between open sun drying and solar conduction dryer were done and it was found that the solar conduction dryer gives high performance than the open sun drying. It was also found that, the conductive heat transfer mode plays a crucial role in the solar conduction dryer.
- PublicationThermal stability of amorphous sugar matrix, dried from methanol, as an amorphous solid dispersion carrier(Editorial Universitat Politècnica de València, 2018-09-07) Imamura, Koreyoshi; Takeda, K.; Yamamoto, K.; Imanaka, H.; Ishida, N.[EN] Developing a technique to disperse hydrophobic ingredients homogeneously in a water-soluble solid matrix (solid dispersion) is one of the topics that have been extensively investigated in the pharmaceutical and food industries. Recently, we have devised a novel solid dispersion technique (surfactant-free solid dispersion), in which a preliminarily amorphized sugar was dissolved in an organic media containing hydrophobic component, without using any surface active substances, and then vacuum dried into the amorphous solid mixture [Food Chem., 197 (2016) 1136; Mol. Pharm., 14 (2017) 791]. In this study, the physicochemical properties, especially thermal stability of the surfactant-free amorphous solid dispersion, were investigated.
