Abstract
Abstract Continuous production of standardized milk is carried out with a method and apparatus wherein milk is separated into cream and skimmilk, an amount of cream is remixed with skimmilk to produce standardized milk, the standardized milk is continuously tested for fat content, the amount of cream remixed with the skimmilk is automatically regulated in accordance with the fat content of the standardized milk and standardized milk and separated cream are recycled to milk being separated if fat content of the standardized milk is not within prescribed limits.

Claim 1
Independent Claim
354 words
Apparatus for the continuous production of standardized milk having a predetermined fat content from raw milk having a variable and higher fat content which comprises: a. a separator for separating the raw milk into separated cream and skim milk and having an inlet line for feeding of raw milk to the separator, a first discharge line for separated cream, and a second discharge line for skim milk, b. a by-pass line interconnecting said discharge lines for conveying a portion of the separated cream to the skim milk for remixing of cream with the skim milk to provide standardized milk in the second discharge line, and a regulating valve mounted in one of said lines for said separated cream for proportioning the amount of cream remixed with the skim milk, c. means for withdrawing a sample of the standardized milk from the second discharge line, which means is connected with the second discharge line, d. a first two-way valve in the first discharge line downstream of the by pass line for receiving cream not remixed with the skim milk and having a first outlet and a second outlet, a conduit connected to the first outlet for discharge of separated cream from the process, e. a second two-way valve in the second discharge line downstream of the connection of the sampling means to the second discharge line, having a first outlet and a second outlet, a conduit connected to the first outlet of the second two-way valve for discharge of standardized milk from the process, f. a recycle conduit connected to each of the second outlets of the two two-way valves for recycling of separated cream and standardized milk to the separator, g. a fat test and controller for receiving the withdrawn sample and determining the fat content thereof and effective to control the regulator valve, and to control the two-way valves for discharge of separated cream and standardized milk when the fat content of the standardized milk is within preselected tolerances and recycle separated cream and standardized milk to the separator when the fat content of the standardized milk is outside of the preseclected tolerances.

Claim 3
Dependent Claim
86 words
Apparatus of claim 1, wherein the two-way valve in the second discharge line is disposed downstream of the connection of the sampling means to the second discharge line and at such a distance from the connection of the sampling means to the second discharge line, that the volume of the second discharge line between said connection of the sampling means and the two-way valve is equal to the volume of standardized milk produced in the time span of the fat content determination by the fat tester.
Claim 4
Dependent Claim
20 words
Apparatus of claim 1, wherein the regulating valve is disposed in the first discharge line downstream of the bypass line.
Claim 5
Dependent Claim
130 words
Apparatus of claim 1, wherein the regulating valve is disposed in the first discharge line downstream of the bypass line, the two way valve in the first discharge line is mounted downstream of the regulating valve, and the two way valve in the second discharge line is disposed downstream of the connection of the sampling means in the second discharge line, and wherein the two-way valve in the second discharge line is disposed at such a distance from the connection of the sampling means to the second discharge line, that the volume of the second discharge line between said connection of the sampling means and the two-way valve is equal to the volume of standardized milk produced in the time span of the fat content determination by the fat tester.
