Butter making process is the one and the most tedious and time consuming operations in dairy industry especially for small holder farmers. It can be made by churning either cream or soar milk. Depend on acidity of the soar, churning temperature and churn speed, 20 – 22 litter of soar milk required to obtain a kg of butter. The churning takes place in various traditional vessels including gourds and clay pots, and it takes more than two hours for butter to form. Considering the above stated problem, an attempt has been made to develop motorized milk churner machine by agricultural engineering directorate of Ethiopian agricultural research institute and performance evaluation was conducted in two regions (Adami-Tulu and Melkassa) with an objective of developing and evaluating churning equipment. The materials selected for fabrication will not contaminate the extracted butter. The ...
