A sauna drying techniqueââ?¬â?the solar drier was designed and imposed, constructed and tested\nfor drying of seaweed. The seaweed moisture content was decreased around 50% in 2-day sauna.\nKinetic curves of drying of seaweed were known to be used in this system. The non-linear regression\nprocedure was used to fit three different drying models. The models were compared with\nexperimental data of red seaweed being dried on the daily average of air temperature about 40C.\nThe fit quality of the models was evaluated using the coefficient of determination (R2), Mean Bias\nError (MBE) and Root Mean Square Error (RMSE). The highest values of R2 (0.99027), the lowest\nMBE (0.00044) and RMSE (0.03039) indicated that the Page model was the best mathematical\nmodel to describe the drying behavior of sauna dried seaweed. The percentage of the saved time\nusing this technique was calculated at 57.9% on the average solar radiation of about 500 W/m2\nand air flow rate of 0.056 kg/s.
