Review Paper on Design Aspects of Stirrer Shaft Butter Extraction Machine

Traditional Butter Extraction Machine is developed & fully mechanized in automated form using electromechanical application in previous study. In present scenario many different kinds of butter extraction machine working on different principles and mechanisms. When shaft is rotated in clockwise and anticlockwise direction & vice versa, stirrer shaft is continuously rotated without lagging. One end of stirrer shaft is fixed and other end is freely rotating (over hanging) during butter extraction, due to centrifugal force jerk acted on shaft. During extraction process, stirrer shaft moves away from the center of axis of rotation. Study on design of shaft for continuous clockwise and anticlockwise rotation, in highly efficient machine for stress calculation & fatigue failure is to be carried out using ANSYS & analytical methods. The study implies on parameters like diameter, material, length & speed of motor for butter extraction machine. Analysis of stirrer shaft & stresses occur during twisting moment can be carried out to be optimized. Aim & Objective of study is to re-design and fatigue failure analysis of the stirrer shaft. Length & critical speed can also be studied for further analysis as future scope of study.
