Abstract
Oat-based cookies is a type of cookies which has harder dough compared to normal cookies due to the addition of pat and other large inclusions into the dough such as nuts and chocolate chips. Due to unavailability of the suitable machine to shape oat based cookies dough with large inclusion, inconsistency in size will be the critical issue. Thus, the development of suitable machine is needed in improving the quality of the final product. The objectives of this project are to develop conceptual designs and refined design of an oat-based cookies machine and to perform mechanical analysis on the chosen part of the machine using analytical software. The process in producing the best design involved possible conceptual designs generation, concept evaluation using Pugh matrix analysis and conceptual design evaluation using concept scoring matrix. The final design selected from the conceptual design evaluation process is refined to be the finest design. All drawing is produced using AutoCAD 2016. Final design consists of several components which are hopper with roller, conveyor belt for the tray to pass through. The process involve in shaping the cookies dough including inserting the cookies dough manually into the hopper and then cutting the dough cookies from nozzles. Next, the dough will be shaped following the shape of the mold on conveyor belt. Trays will be moved on the second conveyor belt. The shape dough will be automatically arranged on the tray. Two parts of the machine which are a roller in the hopper and the critical part of the machine, the leg support, which support the entire weight of the machine, was analysed using Finite Element Method by Solidwork 2014. Based on the analysis, the roller and the hollow structure of the leg support were found to be able to support the overall weight of the machine and during production process. Static component strength against crack is calculated in order to be compared with the value of equivalent stress obtained from stress analysis by Solidwork. The roller and leg support is made up of silicon and stainless steel 304 respectively. The results showed that the hopper will able to withstand up to 15.31Mpa weight and the leg support able to tolerate up to 827MPa weight exerted on them before cracked.
