Method for producing fresh milk having a longer shelf life

Abstract

A method for producing fresh milk having a longer shelf life. The method steps include: providing raw milk; and performing an at least two-step centrifugal germ removal process of the raw milk before a standardization process of the raw milk is carried out. A method may also include performing a first step of a two-step centrifugal germ removal process before a skimming process separating skimmed milk is carried out and performing a second step of the two-step centrifugal germ removal process during the carrying out of the skimming process separating skimmed milk.

1 . A method for producing fresh milk having a longer shelf life, the method steps comprising:
 providing raw milk; and   performing an at least two-step centrifugal germ removal process of the raw milk before a standardization process of the raw milk is carried out.   
     
     
         2 . A method for producing fresh milk having a longer shelf life, the method steps comprising:
 providing raw milk:   performing a first step of a two-step centrifugal germ removal process before a skimming process separating skimmed milk is carried out; and   performing a second step of the two-step centrifugal germ removal process during the carrying out of the skimming process separating skimmed milk.   
     
     
         3 . The method as claimed in  claim 1 , further comprising the step of heating the milk after the standardization process is carried out. 
     
     
         4 . The method as claimed in  claim 3 , wherein the heating is carried out regeneratively at 70-85° C. 
     
     
         5 . The method as claimed in  claim 1 , further comprising the steps of:
 heating the raw milk to a predetermined skimming temperature;   skimming the raw milk;
 dividing out an amount of cream on the basis of predetermined guide values; 
   standardizing the milk by a mixing of the skimmed milk and an homogenized cream;   heating the standardized milk;   hot-holding the standardized milk;   cooling the standardized milk; and   packaging the standardized milk.   
     
     
         6 . The method as claimed in  claim 5 , wherein the at least two-step centrifugal germ removal is carried out after the standardizing of the milk and before the packaging of the standardized milk. 
     
     
         7 . The method as claimed in  claim 5 , wherein at least one step of the at least two-step centrifugal germ removal process is carried out after the heating of the raw milk and before the skimming, and a second step of the at least two-step centrifugal germ removal process is subsequently carried out. 
     
     
         8 . The method as claimed in  claim 7 , wherein the amount of cream is heated for germ removal after the skimming of the raw milk. 
     
     
         9 . The method as claimed in  claim 5 , wherein the amount of cream is heated for germ removal after the skimming of the raw milk and before the dividing of the amount of cream. 
     
     
         10 . The method as claimed in  claim 5 , wherein the packaging is carried out as an aseptic packaging. 
     
     
         11 . The method as claimed in  claim 1 , wherein at least one step of the at least two-step centrifugal germ removal process is carried out in a separator having a disk stack made of separation disks. 
     
     
         12 . The method as claimed in  claim 11 , wherein the separator includes fins, which fins are arranged radially outside the separation disks in a drum of the separator. 
     
     
         13 . The method as claimed in  claim 1 , wherein a recirculation of a phase from a fraction of milk removed during the method that has been sterilized of bacteria is not recirculated into the fresh milk from which germs have been removed. 
     
     
         14 . A method for producing fresh milk having a longer shelf life, the method steps comprising:
 providing whole milk;   performing an at least two-step centrifugal germ removal process after a standardization process of the whole milk is carried out.
