Abstract
In a method for mechanically extracting milk, the pressure in the pulsator chamber of a teat cup is, with regard to the milking vacuum effective below the teat, controlled in such a way that, with due regard to a pressure which is required for folding in a teat rubber and which depends on the respective teat rubber used, a pressure difference between 5 kPa and 35 kPa will act on the teat in order to avoid pathological modifications of the teats.
Claims12
A method of mechanically extracting milk, comprising the steps of:
- applying a substantially constant milking vacuum below a teat to be milked, so as to extract milk from the teat;
- discharging the milk extracted by introducing a substantially constant stream of air into a milk discharge line coupled to the teat;
- and
- controlling a pressure in a pulsator chamber formed between a teat rubber, surrounding the teat and a teat cup such that during a teat relief phase a pressure difference with respect to the milking vacuum is obtained, wherein the pressure difference is selected such that, depending on a fold-in pressure required for folding in the teat rubber, the pressure difference acting on the teat being in a range from 5 kPa to 35 kPa.
