Uppfinningen avser aven en mjalkkylningsrnetod i anslutning till en sadan mjalkkyltank, BAKGRUND Vid mjolkningsanlaggningar far djur maste mjalken kylas en viss tid innan rnjolken hamtas och transporteras till ett mejeri. Kylning av mjalken är nadvandig for att inte mjalkkvaliteten ska forstoras. I en mjalkkyltank vid en mjalkningsanlaggning far djur fbrvaras mjalk vid ungefar 4 grader celsius. TECHNICAL FIELD The present invention relates to a milk cooling tank for storing milk at a milking plant for animals. The invention also relates to a milk cooling method in connection with such a milk cooling tank, BACKGROUND In milking systems, animals must be allowed to cool the milk for a certain time before the buttermilk is collected and transported to a dairy. Cooling the milk is necessary so that the milk quality is not increased. In a milk cooling tank at a milking parlor for animals, milk is stored at approximately 4 degrees Celsius.
Vid mjalkningsanlaggningar far djur dar atminstone en autornatisk mjalkningsstation anvands far den fullstandigt automatiska mjolkningen av mjalkdjur fladar mjalk kontinuerligt eller flodar mjolk intermittent med relativt korta tidsintervall mellan mjolkningarna in i en mjalkkyltank. Detta innebar att varrn mjolk fran den automatiska mjolkningsstationen kontinuerligt tillfars mjalkkyltanken, atminstone vissa perioder under en dag. Den kontinuerliga tillfarsein av varrn mjolk medfar att dot kan vara svart att bibehalla en lag temperatur I mjalickyltankens inlopp. In milking parlors, animals where at least one automatic milking station is used may have the fully automatic milking of dairy animals continuously flatten milk or flow milk intermittently with relatively short time intervals between milkings into a milk cooling tank. This meant that each milk from the automatic milking station was continuously supplied to the milk cooling tank, at least for certain periods during a day. The continuous supply of each milk means that the dot may be black to maintain a low temperature in the inlet of the milk cooling tank.
Detta kan farorsaka problem med bakterietillvaxt for mjolkkyltankar dar tiden rnellan tamningar är I 72-tirnmars interval'. This can cause bacterial growth problems for milk cooling tanks where the time during taming is in the 72-hour interval '.
