Development and construction of a manual orange juice extractor

Project Abstract

The manual orange juice extractor is a project aimed at developing an efficient and user-friendly device for extracting juice from oranges. This research focuses on the design, construction, and testing of a manual orange juice extractor that is affordable, easy to operate, and yields high juice extraction efficiency. The project involves the use of engineering principles to design a mechanism that can effectively extract juice from oranges with minimal effort from the user. The manual orange juice extractor consists of several key components, including a pressing mechanism, a collection container for the juice, and a handle for manual operation. The pressing mechanism is designed to apply pressure to the oranges placed in the device, squeezing out the juice while separating the pulp and seeds. The collection container is strategically positioned to collect the extracted juice, ensuring minimal spillage and easy access for pouring. The design process involves careful consideration of factors such as the mechanical advantage of the pressing mechanism, the materials used for construction, and the overall ergonomics of the device. Prototyping and testing are essential steps in the development process to evaluate the performance of the extractor and make necessary adjustments for optimal efficiency. The manual orange juice extractor offers several advantages over traditional methods of juice extraction, such as hand-squeezing or using electric juicers. It is portable, making it suitable for use in various settings, including households, restaurants, and outdoor events. The manual operation eliminates the need for electricity, making it a cost-effective and eco-friendly alternative for juice extraction. The efficiency of the manual orange juice extractor is determined through testing its juice extraction rate, user satisfaction, and durability. By collecting feedback from users and conducting performance tests, the design can be refined to meet consumer needs and preferences. The goal is to create a product that not only simplifies the process of extracting orange juice but also enhances the overall user experience. In conclusion, the development and construction of a manual orange juice extractor present an innovative solution for juice extraction that is efficient, user-friendly, and cost-effective. By leveraging engineering principles and design considerations, this project aims to provide consumers with a practical and convenient tool for enjoying freshly squeezed orange juice.

Project Overview

<p> </p><p><strong>&nbsp;Introduction </strong></p><p>Oranges are one of the most popular fruits for eating out hand and most important source of fresh juice having a distinctive flavour and high amount of vitamin A B and C (Aye et al., 2012).</p><p>The orange fruit is a specialized type of berry known to the botanists as hesperidia. It has a soft, pithy central axis surrounded by 10-15 segments containing pulp and juice. Enclosing the segments is a leathery segment which contains juice that is sugary; several organic acids (chiefly citric acid) many other components; which give it a distinctive flavour; and high amounts of vitamins A, B and C. (Aye et al., 2012).</p><p>Oranges grow on evergreen trees of the family Rutaceae. The trees grow to a height of about 30 feet (9m) and are symmetrical and upright. The fruit varies in the number of seeds, from none to many. Orange is one of the major source of vitamins among other fruits in the world and it is globally recognized (Wiseman, 2013). In Nigeria, orange is mostly found in the middle belt particularly in Benue state that is commonly known as food basket of the nation as its slogan.</p><p>A very large number of orange is harvested yearly in Benue state and exported to other part of the country where it is either consumed naturally or converted to juice in addition with other fruits (Wiseman, 2013).</p><p>Orange trees are widely grown in tropical and subtropical climates for their sweet fruit. The fruit can be eaten fresh, or processed for its juice or fragrant peel. As of 2012, sweet oranges accounted for approximately 70% of citrus production (Bailey and Robert, 1998).</p><p>The need to meet household demand for freshly made fruit juice is of paramount interest to all those who desire to take juice at its natural state without adding any preservative to it.</p><p>Orange is one of the most important fruits and source of vitamin desired to be consumed in its natural and fresh nature that allow the consumers to benefit from it. Medically, orange serves as a catalyst to facilitate digestion and also as a means of reducing constipation in adolescents (Christopher, 2015).</p><p><strong>1.2 &nbsp; &nbsp; &nbsp; Statement of problem</strong></p><p>Manual orange juice extraction using hands have low capacities and low efficiencies, sometimes un-hygienic, and can hardly meet demand for large quantities of juice. Extraction of orange juice using electrically powered juicers has the limitations of irregular supply of power and sometimes most electrically power juicers are expensive to buy and may require regular maintenance.</p><p>In order to optimize the volume of juice extracted using a manually with manual extractor, there is need to develop &nbsp;an orange juice extractor using stainless steel to obtain juice from oranges with little effort and meet home demand for hygienic and fresh orange juice.</p><p><strong>1.3 &nbsp; &nbsp; &nbsp; Aim and objectives</strong></p><p><strong>1.3.1 &nbsp; AIM: </strong>The aim of this project is to develop a manually operated juice extractor that will extract juice from the orange fruit using stainless steel and encourage hygienic fresh orange juice consumption.</p><p><strong>1.3.2 &nbsp; &nbsp; &nbsp; </strong><strong>Objectives:</strong></p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; a. &nbsp; &nbsp; &nbsp; &nbsp; To develop a manually operated juice extractor</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; b. &nbsp; &nbsp; &nbsp; &nbsp; To construct the juice extractor</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; c. &nbsp; &nbsp; &nbsp; &nbsp; To evaluate the constructed juice extractor</p><p><strong>1.4 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </strong><strong>Justification</strong></p><p>Development and construction of manually operated orange juice extractor will in many ways discourage the consumption of juice containing artificial preservatives which might be harmful due to long term consumption. The constructed juice extractor will require no special skill to operate it, should be affordable, portable and attractive using stainless materials.</p><p><strong>1.5 &nbsp; &nbsp; &nbsp; Scope and limitation</strong></p><p>This project work is limited to the development and construction of a manual orange juice extractor using stainless steel.</p> <br><p></p>
