Abstract

The design and development of the dabai nut cracker is purposely to help the promotion of dabai fruits where it is until now still considered as an underutilized fruits because of lack of research studies on the fruit itself. The design meanly is to help the worker to crack the seeds of the dabai fruits where the nuts inside the seed can be obtained. The design is to help in solving the difficulties in cracking the nuts of dabai fruits, difficulty in accessing the whole kernel when using ready stock nutcracker because the uniqueness of the share where it has triangular/oval shape and the shell is very hard to rupture. Other problem to be solved with this design is to get a specific nut cracker for Dabai nut. The nuts from the seeds can also be consumed as it tastes like peanuts. There are also recent findings indicates that the nutritional quality of the nut is most likely to be similar to the composition of palm oil such as the palmitic acid, linoleic acid, and linolenic acid. The main objective of this project is to design and evaluate the performance of the device itself and also develop the device if there is any improvement or modification that can apply more to the design. The detail design drawing is made using the SOLIDWORKS software as the main platform as it is the most suitable software in drawing the design of tool. The fabrication of the device is being done performance test is carried out to determine the production capacity and efficiency of the tool. The dimension of the toll is 351 mm (upper part length) x 250 mm (bottom part length) x 144.09 mm (height) x 100 mm (width). The desired results from the tool are the kernel of Dabai nut in a whole and all the shells is separated from it. The performance capacity of this tool is 1.64 kg/hr. dried Dabai nut will load to the jig holder according to its sides. The sizes has been determined to be big and small size. The jig holder slide into the bottom dies. The top die cracks the nut when is pressed by the roller when it is in touch with the press handle. After cracking process of the nuts, the jig holder is removed and the kernel is separated from the shell. When the nut is removed from the jig holder, the kernel will detached from the shell. The most important features of this toll are it has a jig to holds Dabai nut accordingly to the unique shape of the nut compared to other general nutcracker exist in the market. The tool gives 97.27% in overall efficiency and because of this high performance of the machine, it would help to cracking Dabai nut for kernel process especially in producing alternative cooking oil that have high potential to burst into market to stand along others cooking oil in Malaysia. Furthermore, all objective of this project has been successfully determined.
