Abstract

Directly after milking, milk is heated above 50 (60-80) deg.C milk collection, storage in agricultural installations and milk transport take place in heated condition, above 50 (60-80) deg.C. On arrival at dairies, the milk is already pasteurised. The energy supplied can be made use of. Energy saving is considerable. Milk quality is very good and bacteriologically improved w.r.t. milk obtd. by process comprising cooling to 8 deg.C, storage transport to dairies and heating to 72 deg.C. Yield in cheese mfr. is increased. In dairies, the milk is pref. stored above 50 deg.C. The energy supplied to dairies with the hot milk can be recovered, e.g. with heat pumps. The recovered energy can be used for (i) the heat-treatment, e.g. evapn. and drying, of milk and milk derivs. and (ii) the heat-treatment, e.g. drying, of agrarian prods., e.g. grass.

Description

Verfahren zur Behandlung der MilchMethod of treating milk

Ublicherweise wird die Milch nach dem Melken gekühlt auf Temperaturen unter 800,darnach gelagert und in kühlem Zustand zu den Molkereien transportiert.Usually the milk is cooled to temperatures after milking below 800, then stored and transported to the dairies in a cool state.

Der Nachteil dieses Verfahrens ist daß die Mikroorganismen durch Kühlung nicht abgetötet sondern nur.konserviert werden und daß ein doppelter Energieaufwand vorkommt weil die gekühlte Milch in den Molkereien auf Temperaturen höher als 72 C erhitzt werden muß.The disadvantage of this process is that the microorganisms by cooling not killed but only preserved and that a double expenditure of energy occurs because the chilled milk in the dairies is heated to temperatures higher than 72 C needs to be heated.

Erfindungsgemäß könnnen die beiden Nachteile ausgeschlossen werden,wenn die Milch nach dem Melken auf eine Temperatur zwischen 60<Jund 800C erhitzt wird.According to the invention, the two disadvantages can be excluded if the milk is heated to a temperature between 60 and 800C after milking.

Bei der Lagerung,nach 30 Minuten tritt dann bekannterweise der Pasteurisationseffeckt ein und die M'kroorganismen werden abegetötet.During storage, pasteurization is known to occur after 30 minutes and the microorganisms are killed.

Der Energieaufwand für die Erhitzung ist nicht höher als der Aufwand für die Kühlung.The energy expenditure for the heating is not higher than the effort for cooling.

Wenn die Milch mit einer Temperatur zwischen 600 und 70<C in den Molkereien ankommt ist sie schon pasteurisiert.If the milk has a temperature between 600 and 70 <C in the When it arrives at dairies, it is already pasteurized.

Die mitgebrachte Energie ist ein Geschenk für die Molkereien und kann nach Bedarf für thermische Verfahren verwendet werden.The energy you bring with you is and can be a gift for the dairies be used for thermal processes as required.

Wärmepumpen können eingesetzt werden.Heat pumps can be used.

In diesem Zusammenhang ist es vorstellbar daß die Molkereien ohne Kesselhaus funktionieren können.In this context it is conceivable that the dairies without Boiler house can work.

Pracktische Versuche haben ergeben,daß die Herstellung von Milschprodukten aus einer Milch, die wie oben beschrieben behandelt worden ist ohne Schwierigkeiten erfolgen kann und das die Qualität sehr gut ist,von der Bakteriologie her noch besser als beim normalen Verfahren.Practical experiments have shown that the manufacture of milk products from a milk which has been treated as described above without difficulty and that the quality is very good, even better in terms of bacteriology than with the normal procedure.

Bei der Käseherstellung erhöht sich die Ausbeute.When making cheese, the yield increases.

Volkswirtschaftlich wird die Einführung dieses Ver fahrens bedeuten daß Energleersparnisse in hunderten von Millionen DM erzielt werden können.In economic terms, the introduction of this procedure will mean that energy savings in the hundreds of millions of DM can be achieved.

Claims

Claims: 1. A method for treating milk directly after milking, for collection, storage at the farms and for the transport of the milk to the dairy farms characterized in that the milk immediately after milking to a temperature higher than 50 ° C, preferably up a temperature of 60vc to 8C> C and that the collection, storage at the farms and the transport of the milk in the heated area State at temperatures higher than 50 C, preferably at temperatures between 60 C and 80 C takes place.

2. The method according to claim 1, characterized in that the storage The milk in the olkerein takes place at temperatures higher than 500.

3. The method according to claim 1 and 2, characterized in that the energy brought back with the hot milk in the dairies is recovered and that, for example, heat pumps are also used for this.

4. The method according to claim 1, 2 and 3, characterized in that the recovered energy for thermal treatment (e.g. evaporation and drying) is used by milk and milk derivatives.

5. The method according to claim 1, 2, 3 and 4, characterized in that the recovered energy for the thermal treatment (e.g. drying) of agricultural products (Grass) is used.
