<![CDATA[Coffee processing roasting process technology is still limited, with processing usingtraditional roasting methods. This takes a long time and the temperature cannot be regulated asrequired. Therefore, roasting machine innovation is required to create a 5 kg capacity automaticcoffee roasting machine. The innovative roasting machine was designed with the quality of theengine frame in mind.The study prepared in this report aims to complete the steps of the processof designing, calculating and testing the framework of a 5 kg capacity coffee roaster. The design,calculation and analysis of the frame system examines the calculation of the material, calculationof the load, balance of labor, stress analysis, displacement, safety of the factors on the heatingchamber frame, the top cover frame, the stepping motor frame, the calculation of welded joints.Based on the results and discussion, the frame material uses ASTM A36 steel with a square hollowstock profile measuring (30 × 30 × 1.2) mm. Welding is done by welding the butt joint, T joint andcorner joint. The permissible stress value of the material is 176.72 N/mm2. The load on the heatingchamber is 3,920 N/mm2, on the upper frame cover 1,263 N/mm2 and on the stepper motor 4,947N/mm2. The stress value for the frame is 47N/mm2 (Mpa), the displacement value is 0.41mm, thesafety factor value is 8.Keywords: : Roast, Frame, Material, Test, Safety of Factor]]>
