Seduh Kopi Coffee Shop is a coffee shop which has its own roasting machine with 2-kilogram capacity for roasting process. The reason of designing this roasting machine because of the expensive price of new machine in the market with small capacity (400 gram) for roasting process. Benchmarking activities needed for comparing the previous machines in the market before designing this roasting machine utilize the VDI 2221 method. This roasting machine consist of important component such as overall frame which is made from 50 x 35 Unp Iron and has function as an engine mount, roasting machine tube which is made from 2 mm stainless steel plates, The axis for spinning process is made from hss or solid round Iron, Tube Cover, input and output machine for coffee roasting are also made of Stainless Steel plates. The prime mover of this coffee roasting machine utilizes AC 220 V motor which function as prime mover connecting with Sprocket-Chain and Vbelt-Pulley.
