Abstract A process for standardizing milk is disclosed, which includes continuous separation of raw milk into cream and skimmed milk and immediate, continuous reblending of a portion of the cream with the skimmed milk to provide blended milk, while the remainder of the cream is recovered as a byproduct. The blended milk is continuously sampled and tested to determine its fat content and the actual fat content is continuously compared with a predetermined fat content. The amount of cream reblended with the skimmed milk is automatically regulated to provide the desired fat content in the blended milk product. Apparatus employed includes a separator, conduits for separately removing skimmed milk and cream from the separator which are interconnected to mix the desired portion of cream with the skimmed milk, a milk sampler for withdrawing blended milk samples, a milk fat content tester, an adjustable valve in the cream removal conduit, and a valve controller for controlling the rate of withdrawal of byproduct cream in response to the fat content of the blended milk determined in the tester.

Claim 1
Independent Claim
149 words
A process for producing a blended milk product having a predetermined fat content from raw milk, which comprises the steps of: a. continuously introducing a stream of said raw milk into a milk separation zone and separating said raw milk stream to provide a skimmed milk fraction and a cream fraction; b. continuously and separately withdrawing said skimmed milk fraction and said cream fraction from said separation zone; c. continuously splitting said cream fraction into a first portion and a second portion and removing said first portion from the process; d. continuously admixing said second portion with said skimmed milk fraction to provide a blended milk stream; e. continuously testing said blended milk stream to determine the fat content thereof; f. continuously comparing the fat content of said blended milk stream with said predetermined fat content; and g. continuously controlling the amount of said second portion of cream to
