Abstract:

The development of milking systems is one of the most important examples proving the dynamic improvement of dairy production on the basis of a technical infrastructure. Farm milking systems incorporate many technical solutions—this provides a basis for analysing and assessing different milking systems in use today. Milking systems can be evaluated on the basis of a set of data and indices directly connected with the work of milking installations. The purpose of the analysis is to show how different kind of milking systems can be assessed in view of milk and its selected features, especially the value of the milk.

Abstract:

This paper deals with the measurement of the modern method of producing and regulating the vacuum in milking equipment which is currently in use. Individual measurements are primarily focused on evaluating the latest knowledge in the design, management and stabilization of the vacuum in modern milking systems. In the evaluation, emphasis was placed on economic efficiency with regard to energy consumption, environmental friendliness, high performance, operational reliability and ease of operation in the creation and control of the vacuum. The basic element of every milking system is the vacuum pump. This feature of the machine provides a vacuum for milking, milk transportation and for the activities of other devices whose task is, e.g., scanning the milking equipment or controlling movable barriers at milking parlours.
In this paper, a frequency converter was used, which is, used in milking technology for regulating and controlling the vacuum through changing the rotational speed of the vacuum pumps which do not require the use of centrifugal force to seal the working space to create a vacuum. The aim of the measurements using the above-mentioned inverter was to check the performance of the pump at different speeds and different vacuum levels to determine the actual air flow need over the milking cycle.
