Optimalisasi Dimensi Tabung Roasting Kopi Kapasitas 2 kg dengan Pendekatan Model Elemen Hingga

Coffee roasting is an important process in the coffee industry that determines quality of beverage obtained. The carried out a cylindrical tube having high temperature. Therefore, thermal stress on (drum) should be focused. In this paper, both appropriate materials selection and optimal dimension roaster drum are considered. Drum given load 200 o C 2 kg. Here, Aluminum Alloy 5083 Stainless Steel 304 analyzed as because these recommended for foods. Finite element method used analysis with axisymmetric model. Moreover, can obtained by varying length, diameter thickness. results show suitable material under While, dimensions length 450 mm 180 thickness larger than 1 mm.
