Convective Drying of Ganoderma tsugae Murrill and Effect of Temperature on Basidiospores

Abstract

In this study, drying of Ganoderma tsugae Murrill slices was carried out at different temperatures in a hot air circulating oven. The objectives were to investigate the drying characteristic and drying kinetics of the Ganoderma slices under constant air velocity and slice thickness. In addition, the effect of drying temperatures on the size and surface structure of Ganoderma tsugae basidiospores were studied. Using statistical analysis, a two-term model was found to fit best with the experimental data. Convective drying of Ganoderma tsugae slices at 60°C shows the minimum heat deformation to the size and surface structure of basidiospores.
