“…Although P. radiata and Maxican pine have different thermo-physical properties, they represented similar equilibrium curves. Moreno et al (2004) fitted the equilibrium isotherms for biomass particles of P. radiata by using a GAB model. The equilibrium curves depicted a similar behavior compared with our results at 30°C.…”

A desorption isotherm is a very important basis in the understanding of drying process. In this study, the desorption isotherms from the sapwood of Mexican pine (Pinus pseudostrobus Lindl.) were determined by the gravimetric method (discontinuous control of sample weight) at 30°C and 50°C. The salt method was used in the range of water activities from 0.11 to 0.89. The results show that the desorption ability of Mexican pine sapwood increased with temperature at a given relative humidity. The experimental data was further simulated with the models, i.e., BET, GAB, Oswin and Henderson models. The GAB, Oswin and Henderson models allow the representation of the entire desorption isotherms. The BET model showed a better fi t for water activity lower than 0.35, with a mean relative deviation of 0.0286 at 30°C and 0.0167 at 50°C. Simultaneously, the BET model gave a better representation of moisture content in the monolayer saturation region. Overall, the GAB model ensured the best simulation of the entire isotherm, while the Henderson model displayed the worst simulation.

“…Moreno et al [68] studied biomass (forestry wastes) drying in a fluidized bed. They found that high temperatures (close to 187 °C) are advantageous, since preliminary experiments showed that high inlet air temperature meant a low system energy consumption due to a greater drying rate.…”

The proper treatment of organic or inorganic solid wastes meets economic and especially environmental interests. Added-value by-products of market interest can be obtained through the recovery, reuse and treatment of solid wastes, which are otherwise discarded inappropriately in large quantities in the environment. In this review, the drying process is presented as an alternative environmental technology for the thermal treatment of residues of different natures from different origins. The main techniques applied to solid waste drying are described and in parallel the most relevant studies found in the literature which approaches this theme are analyzed. Moreover, the main dryers used nowadays are presented, as well as their most important characteristics. Some general aspects of the thermal and energetic performance of these dryers fundamental for process feasibility analysis are also discussed in this review. Essential aspects of the solid waste drying process are primarily presented with the purpose of showing the particularities that this theme offers when it comes to putting the theory into practice.

“…1. According to the work of Moreno et al [32] concerning the equilibrium moisture content of Pinus radiata, drying to a moisture content of 20 wt-% (wb) requires an air-relative vapor pressure (ratio of partial pressure of water vapor in the mixture to the saturated pressure of water vapor) of 90 % at 20°C.…”

Innovative Energy‐Efficient Biomass Drying Based on Self‐Heat Recuperation Technology

et al. 2011

A novel drying system based on self-heat recuperation (SHR) technology, which recuperates both sensible and latent heat, was developed to reduce effectively the energy consumption for biomass drying. A fluidized bed dryer with internal heat exchangers was selected as the main dryer. Square wood chips of Pinus radiata with average dimensions of 10 mm were selected as biomass sample. The relation between the required energy input and fluidization velocity and a comparison with the available mechanical vapor recompression (MVR)-based drying technology were evaluated. The results prove that the proposed SHR technology could reduce the required energy consumption for biomass drying significantly at all evaluated fluidization velocities to about 2/3 of that required for MVR-based drying technology.
