Standard and Superheated Steam Schedules for Radiata Pine Single-Board Drying: Model Prediction and Actual Measurements

An assessment was made on the predicted drying behavior with its actual measurement for a radiata pine single-board drying model. The predicted temperature profiles within the board showed reasonable agreement compared with experimental drying tests using both fibre optic and thermocouple sensors. The agreement between predicted drying rates and its measurements was acceptable. This model was used to assess predicted drying behavior applying schedules (dry-bulb/wet-bulb: 140/90°C, 140/99°C, 160/90°C, 160/99°C). The difference in drying rate was small for wet-bulb at 90°C compared with that at 99°C.
