Ingeniería de Sistemas y Automática of the University of Seville.The plant makes use of a distributed control system that allows the control and integral monitoring of the drying process.
Kaeser refrigeration dryers protect against line corrosion, machine failure and product damage down to an ambient temperature of +3 °C. Ensure reliable and low-cost protection – thanks to sturdy design, high-quality equipment features, such as the ECO-DRAIN condensate drain and surprisingly low energy consumption.. In addition to our compact basic line, our energy-saving refrigeration ...
Drying is ubiquitously used operation that improves on storage life of agricultural produce, either solid, liquid or slurry. Most dryers with relatively advanced technologies are expensive while the cheaper ones are manually regulated. This paper aimed at development of a direct and con-current rotary dryer that uses rolling action with hot air to effectively remove moisture from materials.
