Abstract

A milking plant for cows is provided with a milking machine comprising teat cups, which are connected separately to the teats of an animal. The milk obtained from each udder quarter is conveyed through a separate line to a milk measuring device. The milk measuring device includes four milk meters, one for each teat cup, having separate discharge lines coupled to common discharge lines which connect with a circulation line or loop that includes a bulk milk cooling tank, a two-speed or variable speed pump, and a plurality of heat exchangers for precooling the milk received from the common discharge lines before it is received in the bulk milk cooling tank and to recirculate and cool the milk received in the bulk milk cooling tank. After the milk has been discharged from the bulk milk cooling tank and the system is to be disinfected, washed and rinsed, the heat exchangers being used in a heat pump arrangement, can heat the fluid therein as selected and desired for sanitizing the system.
