The present stage of milking machine development can be characterized by appearance of the new designs of milking machine and using automated elements in traditional equipment. One of the trends in the improvement of the milking process is to increase the capacity of milking machine therefore studying of physical and chemical properties of milk (plasticity) are important. To determine plasticity coefficient of milk a new theoretical method and laboratory equipment simulating milk flow in milking machine hoses were proposed. The research has shown sufficient accuracy of the theoretical method for plasticity coefficient calculation, which allows using it in milking machine improvement.
