One of the results of the coconut is coconut oil. To get the oil required several processes such as coconut testa peeling the skin. Coconut testa skin peeling process is still done manually using a special knife that takes time and considerable manpower. In addition, there is a risk of a knife scraped manually peeling process. It required skinner testa machine to increase production capacity and avoid the risks that occur when using the manual method.The shell breaking process has some risk involved,so on heating the shell before deshelling the process would be much easier one.Skinner testa machine design results can peel testa with peeling efficiency of 90% with the time it takes for 15 minutes to peel as many as 15 coconuts. Costs for skin peeling coconut testa cheaper than the manual for a one coconut.The the testa skin is the skin found on outside of the coconut flesh which is not useful if the fruit flesh wants to be processed.The process of seperation of skin from the flesh is done manually.The process of skin peeling done manually using a knife and blade.Testa skin peeling would require a long time and lot of labours.So we need a machine to peel the peeling process involves peel the skin using a rotating drum.The principle of peeling used is the friction between the coconut with the drum and the friction between the coconut. 2021-02-04T00:00:00Z http://localhost:8080/xmlui/handle/123456789/177 Title: DESIGN AND FABRICATION OF PEPPER SEPARATOR MACHINE Authors: BEN AUSTIN B ALAPATT Abstract: The present study was conducted to find a method to separate the seed and peel of camelia ollifera fruit. some domestic scholars have studied a separating device for seed and peel of camellia oleifera fruit with the rapid development of camellia oleifera industry. The purpose of the experiment is to find out optimum mechanical and electrical system for separating seed and peel of the fruit. Although the separating machine for seed and peel of camellia oleifera fruit has achieved certain development, there are generally problems such as low rate of separating and complex structure. Moreover, in many industries even now, the peppers are separated manually. Due to this manual process in industries, there is wastage of money and time. In order to avoid this wastage, we have designed the following model called pepper thresher machine. Therefore, a new type of separator is designed according to the different characteristics of seed and peel, and the single factor experiment and orthogonal experiment were carried out. In this project we fabricate a machine for the purpose of threshing the peppers. This is an advanced and easy process to separate pepper from the plant. In this process we do not need any high electrical supply to operate the machine. This model has the parts, rotating drum, a hopper and cam operated tray arrangement. 2021-04-04T00:00:00Z http://localhost:8080/xmlui/handle/123456789/176 Title: Product design and development of a reading aid for the visually impaired Authors: OS, Sandeep; Gopinath, Ajith; Babu, Shibin; Claudius, Allen Bob; Ismail, Shaik Mohammed Abstract: t. One of the main hurdles for the blind are to read, easily and there by learn and graduate. Various researches are happening to reduce the effort required for the blind to read in terms of aids which can speak out the written data. The current research targets to design and fabricate a reading aid for the visually impaired. This device will help them to identify the text written in any book or page by scanning the text and speaking it out to them with the help of a mobile application called KNFB reader which helps to read anything to blind or dyslexic people. This project utilizes the fact that majority of the people use smartphones, which can be used for the advantage of the blind people. Based on a survey conducted among the blind people with the help of an NGO Anuprayas all the criteria for the design of reading aid, in the current project were selected. Four sample designs were prepared after taking the criteria for reading aid into consideration. Forced Decision matrix (FD) analysis and Decision alternative ratio System (DARE) analysis, which are tools to rank the properties based on the priority, were conducted to identify the most influential parameter for the design. The parameters were ranked based on these analyses. The ergonomics, cost and durability were the most important properties desired in the product. This product can be deployed for the effective utilization by public at railway stations, bus stations, libraries etc. This will enable the blind to be selfindependent and have the information available for them whenever they need it. 2021-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/172 Title: Manufacturing of Friction Stir Welding Tool and Characterisation of Welded Aluminium Alloy Authors: Ben Austin B Alapatt , Goutham D , Eldho Mathew, Majo Davis Abstract: Conventional process like arc welding and gas welding are not suitable for pure aluminium and copper and its alloys due to its low melting point, high thermal conductivity and presence of high impurities after welding. Here introducing an alternative method of welding for such materials known as friction stir welding by drilling machine. Here designed a tool shoulder which accurately fix into the machine. Then after a tool probe, which does the crucial job of friction welding. The tool probe and tool shoulder are manufactured based on the design and then assembled to make the tool and welding is completed. Conducted welding with three different speed and produces weld joint of different properties. Welded specimens taken for nondestructive and destructive testing to compare the mechanical strength, quality of and other mechanical properties of the weld produced 2020-12-20T00:00:00Z
