MATHEMATICAL MODELING OF THIN LAYER DRYING OF SALTED YELLOWTAIL FISH UNDER OPEN SUN AND IN GREENHOUSE DRYER

Abstract

The thin layer dryer model was used to describe the characteristics of changes in water content of salted yellowtail dried under the open sun and by using a greenhouse dryer. Thirteen different thin layer dryer models were used to predict fish water content values. The results of the conducted experiments validated the values. From the results of modeling for open sun drying, it was discovered that Modified Henderson and Pabis were the most suitable models to be used. While for drying using greenhouse dryers, it was suitable to use the Diffusion Approach model and Verma et al. From the performance of modeling indicator, it was shown that the value of the correlation coefficient (R) approaching 1, where the mean square of deviation between experimental, predicted values and root mean square error analysis (RMSE) have infinitesimal values.
