Development of devices for the determination of the rheological properties of coarse biomass treated by dry anaerobic digestion

The lack of rheological characterization of coarse biomass limits the design, operation and optimization of continuous Dry Anaerobic Digestion (D-AD) processes. In this work, three alternative rheological devices for the determination of rheological behavior of coarse biomass were scale-up and calibrated; the slump test, the consistometer and the shear-box. The applicability and limitations of each device were evaluated using artificial mixtures...
