| Abstract | ||||
| The aim of the present study is to construct and evaluate a centrifugal milk separator for cream and skim milk production. The milk separator consists of five main parts: power source, transmission system, collection milk vessel, centrifugal separation unit and production collectors. The centrifugal separation unit consists of three parts: housing, separated discs with totally number of 40 conical discs collect and fix in the housing together and stuck base, which fastening the conical discs and the housing together through a stud and Hex. Hd. Nut. Laboratory experiments were conducted to optimize milk feeding rate, separation rotating speed and raw milk temperature degree. While the separator performance was evaluated in terms of cream and skim milk amounts,skim milk fat percentage, separation efficiency, specific energy and operational cost of milk separation. The experimental results reveal that the milk separator is recommended to be used under the following conditions to give the highest cream amount of 35 kg/h with lower specific energy and operational cost of 25.14 kW.h/Mg and 228.60 L.E/Mg, respectively: - Milk feeding rate to the conical separating unit of 400 kg/h. - Separation rotating speed of 8000 rpm. - Temperature degree for the raw milk of 37° C. | ||||
