Design and Fabrication of a Short Roller Sugarcane Juice Extractor Machine.

Abstract

Extracting the juice from sugarcane has been a major problem, especially with the use of a Traditional way that could damage the gum of the teeth and putting the human teeth in distress and require much energy. The main objective of the project is to design a sugarcane juice extracting machine, that will extract juice from sugarcane and that will separate the juice from the sugarcane and the bagasse. The crushing unit is made of three rollers These are 90mm,75mm &70 mm thick diameter and length of 102 mm, The machine was constructed by several well-established methods such as methods, such are as follows: Measuring, Marking Out Operation, Cutting Operation, Welding Operation, Grinding Operation. The machine was tested using a given sample of sugarcane weighting 7 kg, the mass of juice extracted was 3.13 kg, while the extraction took about 2 min. From the design an actual speed of the roller of 46 rpm. The design of the sugarcane juice extracting machine possesses simplicity in operation and maintenance as well as affordable with low running and maintenance costs with reliable efficiency. The Improved Sugar cane juice extractor has short stainless steel removable rollers. The juice extractor includes housing with three compartments, the first for extracting juice and contains the crushing rollers; the third contains the main drive, while the second serves as re-enforcement for the connecting shafts. The first compartment is a closure for accessing the compartment; the closure is preferably a clear plate which permits viewing the compartment during operation and, when removed, allows access to the compartment for removal of the crushing rollers and cleaning of the rollers and the compartment. A safety switch is provided to prevent rotation of the rollers when the closure is displaced. A guide into the compartment is provided to direct the sugarcane and any flavorings into the crushing rollers. A waste channel is provided for the exit of crushed cane pulp.
