<p>Procedure and apparatus for improving the milking process of pipe milking machines with overhead milk pipe. The object of the invention is to improve the udder health of dairy cattle and to reduce the admixing of air to the milk, and thus to improve the stability of the milk quality. As taught by the invention, during the milking a continuous vacuum is maintained in the centre-piece (2) by conducting the air from the centre-piece by an overhead route to a vacuum pipe (3), and the milk by a lower route through a vacuum pipe (4) by the aid of a pump (6) into a milk pipe (12), wherein normal pressure advantageously prevails. The milk is drawn from the centre-piece (2) by means of a piston pump (6) governed by the pulsator (5) of the milking machine and utilizing the vacuum in the vacuum pipe. The piston (7) of the pump (6) sucks during the first phase of each dual beat of the pulsator (5) milk through the vacuum pipe (4) into the milk volume (17) of the pump and during the second phase pushes the milk into the milk pipe (12). </p> |
