Abstract
The present invention relates to a device for injecting a cleaning liquid into a teat cleaning cup (3). Each nozzle means (55a-b) is connected to a corresponding and separate cleaning liquid supplying means (27, 29) for injecting said cleaning liquid alternately through said nozzle means (55a-b). The nozzle means (55a-b) are also so arranged in said teat cleaning cup (3) that when alternately injecting cleaning liquid trough each of said nozzle means the teat (9) is deflected away from the nozzle means (55a-b).
Claims19
Method for cleaning an animal teat, comprising the steps of:
- attaching a substantially cylindrical teat cleaning cup onto a teat to be cleaned during a cleaning session,
- alternating a step of injecting, into an inner space of the teat cleaning cup, a cleaning liquid through a first group of nozzle members with at least one other step of injecting, into said inner space of the teat cleaning cup, a cleaning liquid through at least a second group of nozzle members separated circumferentially from the first group of nozzle members so as to generate pulsating jets of cleaning liquid acting on the teat;
- and
- draining used cleaning liquid from said teat cleaning cup.
Apparatus for cleaning a teat of an animal, comprising a substantially cylindrical teat cleaning cup intended to be attached to a teat to be cleaned, wherein the teat cleaning cup comprises nozzle means for injecting a cleaning liquid into the teat cleaning cup and drainage means for draining used cleaning liquid from the teat cleaning cup,
- said nozzle means comprising at least a first and a second group of nozzle members separated circumferentially in the teat cleaning cup;
