Design and construction of domestic sugar cane juice extraction machine.

Abstract

This project report describes the design, construction and fabrication of domestic sugar cane juice extraction machine which is motorized. This study is to integrate the existing extraction machines which arc complex and high capacity crushers which cannot be afforded by small scale farmers and to encourage people to start consuming sugar cane juice which is useful to human health with few additional features. The reason of developing the design and construction domestic sugar cane juice extraction machine able to extract clean sugarcane juice at household level which is beneficial to human health, easy to operate and affordable to both small scale farmers and people going to consume the health juice which can be operated in closed room. The motorized domestic sugar juice extractor crushes and grinds the horizontally loaded sugarcane stem and presses the macerated stem against the 3 crushing rollers to extract the juice from the wet bagasse. The machine consists of the housing, 3 small shaft, ball bearings, keys, spur gears, 3grooved rollers, hopper, chain and sprockets and electric geared motor etc. The performance tests carried out on the developed machine showed an efficiency of 70.7% and an actual throughput of72kg/hr at low peripheral speeds of rotating rollers at 0.5 m/s.
