Abstract
A method is provided for capturing and discharging pre-milk in a milking device which comprises a milking cup, a vacuum system, a milking glass and a controller. The milking cup comprises a cup sleeve and therein a liner, therein a teat space with a cup milk outflow opening, a milk capture chamber connected thereto with a chamber milk outflow opening and a chamber vacuum opening, and a milk transport line with a milk discharge valve. The vacuum system comprises a vacuum source with a pulsation line, a milking vacuum line at the chamber vacuum opening and a ventilation valve, and a milking glass vacuum line connected to the milking glass. The vacuum system applies a pulsation vacuum, a milking vacuum in the milking vacuum line, and a milk transport vacuum in the milk line. The method comprises connecting the milking cup, milking first milk jets from the teat, ventilating the pulsation space, opening the milk discharge valve and ventilating the milk capture chamber by opening the ventilation valve. Because of the great pressure difference between the milk transport vacuum and ambient pressure during ventilation of the milk capture chamber, the pre-milk is blown out by force from the milk capture chamber. Also a milking device for the method is provided.
