Thin layer green pea husk (pericarp) drying characteristics were evaluated in a laboratory scale tray dryer. The drying experiments were carried out at 65, 70, 75 and 80°C. Mathematical models were tested to fit drying data of green pea husk. The drying process of green pea husk occurred mainly during a falling rate period except for a very short accelerating period at the beginning. Midilli-Kucuk model had the highest R² and lowest Chi squared and RMSE values and therefore can be used to predict the drying behaviour. The average values of effective diffusivity ranged from 5.01 × 10−8 to 9.17 × 10−8 m²/s for drying green pea husk. The activation energy value was 31.55 kJ/mol for the whole falling rate period.

Case study - SP, Technical Research Institute of Sweden
Customer: SP, Technical Research Institute of SwedenProject: WetESP for Fire LaboratoryMany fire tests are made in full scale. Example for fire tests can be engine rooms, vehicles, store houses, compartments etc. Most of the tests will include ignite phase, full fire and extinguishing. The ignite phase is sooting, full fire will give high temperatures (500-700 °C) and the extinguish phase glows and moisture. The laboratory is operated eight hours a day. The plant has to start/stop every day. Year 1999 SP...

Remediation of mercury contaminated industrial site for future expansion - case study
70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building material.A similar but smaller econ industries VacuDry® plant for mercury remediation has been operated in Leipzig, Germany since 2002. To fulfil the client`s requirements...
Exergetic performance assessment of plug flow fluidised bed drying process of rough rice
Exergy analysis of rough rice drying process in laboratory–scale plug flow fluidised bed dryer was carried out. The drying experiments were conducted to assess the effects of inlet drying air temperature, feed mass flow rate and weir height on energy efficiency, exergy destruction, exergy efficiency, entropy generation, improvement potential rate and sustainability index. The energy and exergy efficiency values were found to be in the ranges of 7.97-31.32% and 4.18-12.00%, respectively. Results showed that the...
