MODEL LAJU PENGERINGAN SPAGHETTI JAGUNG MENGGUNAKAN TRAY DRIER [Drying Model of Corn Spaghetti using Tray Drier]

Drying is the most crucial process that determines the final quality of pasta products. Drying at high temperature has been widely used; however, it may cause texture damage in the form of cracking in the product. Drying model can be used in drying process control to prevent such kind of damage and also to design an optimum drying condition. The objective of this research is to determine the drying model of corn spaghetti using a tray drier. In this study, drying was performed at three levels of air velocity (1.29; 0.90; and 0.49 m/s), three levels of instrument temperature setting (6, 8, and 10), and two setting of drying position (vertical and horizontal to the airflow). Results indicated that drying temperature was the most influencing parameter in corn spaghetti drying. It also could be concluded that the drying rate of corn spaghetti could be well represented by thin layer drying equation (Page model).
