Abstract

This research explores the evolution of technology in pineapple peeling, from the use of manual knives to sophisticated pneumatic technology. The main focus is on pineapple peeling machine design, working principles, and calculating time efficiency between machine and manual peeling. The aim is to broaden students' understanding of designing machines and provide guidance for students in applying pneumatic technology. The study began with literature observations and field studies to collect price and specification data as well as information components about pineapple. Next, planning, manufacturing, and testing of the machine are carried out. Data was collected from both stripping processes for further analysis. The research results include machine designs with main components such as actuators, knife blades, knife fasteners, and machine frames, as well as pneumatic component specifications, which are explained in detail. A comparison of stripping times shows a significant increase in efficiency with the machine, with the fastest time of 9.09 seconds and the longest time of 447 seconds for manual stripping. This research contributes to the development of pineapple processing technology and increases efficiency in the fruit processing industry as a whole.

Abstract

This study focuses on the design and performance evaluation of a shallot peeling machine aimed at enhancing processing efficiency for culinary applications. The machine is equipped with a ¼ hp electric motor operating at 1400 rpm, along with a specially designed peeling disc that utilizes rubber friction around the drum to effectively peel the shallots. The machine’s large-capacity container is designed to prevent the test materials from being ejected during operation, ensuring stability throughout the peeling process. Testing was conducted in two stages: the first stage used 1 kg of shallots, and the second stage used 2 kg, both at a motor speed of 1400 rpm. In the first test stage, the machine achieved an average peeling efficiency of 82% after one minute (equivalent to 820 grams of peeled shallots from 1 kg), which increased to 94.2% (942 grams) after two minutes and reached 98.5% (985 grams) after three minutes. In the second test stage with 2 kg of shallots, the machine recorded an average peeling efficiency of 96.4% (1929 grams). The machine demonstrates a production capacity of 30 kg per hour, far exceeding the previous model's capacity of only 14 kg per hour. These findings confirm that the newly designed shallot peeling machine meets performance expectations and offers a substantial improvement in peeling efficiency and productivity.

Abstract

The objective of this study is to improve the quality and efficiency of the verification process which is crucial for processing green bean seeds by upgrading the green bean skin separating machine. This change entails improving engine rotation in addition to changing engine mechanics and parts. The engine was tested at 350 rpm, 425 rpm, and 500 rpm during the experimental phase. According to the data, 350 rpm is the ideal engine speed for separating green bean seeds from the pod skin, with a differential capacity of 54 kg/hour. When ninety percent of the green bean seeds are undamaged and out of the pod skin, they are combined with other components. This machine may serve as a commercial solution to improve the quality and efficiency of processing green bean seeds. These encouraging outcomes highlight how important technology is to the agro-industrial and agricultural sectors. By processing green bean seeds more effectively and of higher quality, technology may also assist the environment and the economy.

Abstract

The swift progression of industrial technology has profoundly influenced the manufacturing sector, especially in the domain of sheet metal manipulation. Hydraulic plate bending machines hold a pivotal role in contemporary production due to their precision in shaping sheet metal components. This study aims to elevate the versatility and efficiency of hydraulic plate bending machines through innovative modifications. Key components underwent substantial alterations, including punch substitution, installation of dual punch locking plates, and integration of a pressure gauge. An evaluation ensued to determine the optimal parameters duration and force requisite for bending sheet metals ranging from 1 mm to 4 mm in thickness, aimed at assessing machinery efficacy. Test outcomes unveiled the modified machine's adeptness in accurately bending sheets of varying thicknesses, affirming its intended functionality. Moreover, the machine's enhanced adaptability allowed for seamless interchangeability of punches with diverse sizes and shapes. These empirical findings provide invaluable insights for enterprises striving to streamline manufacturing processes and boost overall productivity. Notably, this study highlights the pivotal role of technological advances in hydraulic plate bending machines, offering firms an efficient avenue to cater to diverse sheet metal shaping demands, thereby amplifying productivity and adaptability in industrial operations.

Abstract

This research aims to develop and optimize a machine for peeling young coconut skin, increasing production efficiency and improving the quality of peeling results. The research background is based on the need for more efficient tools compared to manual methods, which are only capable of peeling around 45 coconuts per hour. Research methods include designing, assembling, and testing machines with various knife models and electric motors. The design process uses Autodesk Inventor software, and testing is carried out by measuring the stripping time and the quality of the stripping results. This study analyzes the impact of different knife models and motor power variations on the efficiency of young coconut peeling, using a machine with a 1/2 HP electric motor at 1400 RPM capable of peeling 68 coconuts per hour, achieving a 51% increase in production compared to manual methods not only increases time and energy efficiency but also produces more consistent products. The conclusion shows that this young coconut skin peeling machine is able to increase productivity and the quality of peeling results, providing an innovative solution in the young coconut processing industry. This research suggests the use of peeling machines to increase efficiency and quality in processing young coconuts, optimize production, and reduce the risk of work injuries that often occur with manual methods.
