Abstract

The aim of the present study is to manufacture and evaluate batch butter churning machine for butter and buttermilk production from sweet or fermented cream. The new butter making machine consists of five main parts: power source, transmission system, collection cream vessel and cooling unit. The cooling unit consists of five parts: evaporator, expansion valve, condenser, fan, receiver tank, and compressor. Laboratory experiments were conducted to optimize cream loading ratio, churning time and churning temperature. While the churn machine performance was evaluated in terms of butter and buttermilk amounts,buttermilk fat percentage, churn efficiency, specific energy and operational cost of butter churn. The experimental results reveal that the churning machine is recommended to be used to give the highest butter production of 21.20 kg/h with lower specific energy and operational cost of 23.11 kW.h/Mg and 188.21 L.E/Mg, respectively at cream loading ratio of 45 kg/h, churning temperature of 6° C and churning time of 15 min under constant fan speed of 600 rpm.
