Design, Development And Performance Evaluation Of A Fruit Juice Extraction Machine

Abstract

This exploration centers on the design, development and testing of a motorized juice extractor fabricated using locally-available accoutrements . The machine is made basically of two introductory chambers the mincing cube and the juice rooting cube. Other factors include feeding hoppers, top cover, auger conveyor housed in a spherical barrel, juice sieve, juice collector, waste outlet, transmission belt, main frame, pulleys and comportments. In operation, fruits introduced into the mincing cube via the first hopper are diced sliced and passed into the rooting cube via a alternate hopper. The auger conveys, crushes, presses and squeezes the fruits to prize the juice. The juice uprooted is filtered through the juice sieve into juice collector while the residual waste is discharged through waste outlet. When tested for lately gathered pineapple, gusto and orange fruits, results show that the average juice yield for pineapple, orange and gusto were independently 74, 72 and 34; juice birth edge were independently 84, 80 and 71; and juice birth losses were independently 18, 16 and 9 at optimum machine speed of 335 rpm for pineapple and oranges, and 476 rpm for gusto. Powered by a 3hp electric motor, the machine has a capacity to reuse 30 litres/ hr of oranges, 32 litres/ hr of pineapples and 24 litres/ hr of gusto and the machine costs of aboutN 54,600, hence it’s affordable for small- scale growers.

Preface

Background of the Study

Before the discovery of crude oil painting in marketable volume in the 1970s, husbandry was the dependence and sustaining source of the Nigerian frugality. The agrarian sector contributed immensely to the gross domestic product( GDP) of the nation. The discovery of oil painting and the smash that redounded from the exploitation of crude oil painting in the 70’s foisted a big blow on the agrarian sector as all attention was shifted to oil painting, leading to the neglect of this vital sector( Fasanya etal., 2013). colorful programmes similar as Operation Feed the Nation( OFN) of 1976 and the Green Revolution of 1979 were embarked upon to insure that there’s enough food for the ever- growing population of Nigeria. This agrarian eventuality was what Nigeria exploited in thepre-independence and thepost-independence period previous to 1975, which gave it its leadership position internationally in the product and import of agrarian products( CBN, 2004). Well over 50 of the country’s total import earnings came from the agrarian sector previous to the 1970s( CBN, 2004; Ndubisi etal., 2013). likewise, the agrarian sector reckoned for about 50 of the GDP and employed about 72 of the labour force on normal between 1960 and 1970( CBN, 2004; Fasanya etal., 2013).

In developed countries like the USA, Germany, France, Italy, Canada and Great Britainetc., the productivity of the Agricultural sector is always on the increase. These achievements results from their high position of robotization.
