Multi-Purpose Separators 
The special De Laval Multi-Purpose Sepa¬ 
rator has a combination of advantages never 
before incorporated in a Cream Separator. 
This great machine can be used for standard¬ 
izing or raising the butterfat content of whole 
milk to any point desired. 
As a Standardize!". The demand for milk 
of higher butterfat content in some of the 
fluid milk markets of the country, also the 
desire on the part of many dairymen to give 
their customers richer milk, has created a 
need for an efficient means of standardizing 
or raising the butterfat content of low-testing 
milk. The special De Laval Multi-Purpose 
Separator provides a splendid means of 
doing so. 
To standardize with this machine all of the 
milk from a milking is run through it. The 
bowl is adjusted so that a small amount of 
skim-milk is withdrawn through the skim- 
milk discharge of the machine, and the 
remaining whole milk, which is delivered from 
the upper discharge spout of the Separator, 
will test higher. 
The amount of skim-milk withdrawn may 
be varied by bowl adjustment so that whole 
milk of any desired butterfat content may 
be produced. 
Clarifies as it Standardizes. One of the 
advantages of standardizing milk with the 
Multi-Purpose Separator over any other 
method is the fact that running all the milk 
through the centrifugal separator bowl pro¬ 
vides efficient clarification as well as stand¬ 
ardization, and both of these important 
functions are accomplished in one operation. 
It has been proved by many tests and by 
the experiences of many of the country’s lead¬ 
ing milk distributors that clarification is the 
most efficient means of removing dirt and 
foreign matter from milk. It is more effective 
than any method of straining could possibly be. 
As a Regular Separator. The Multi- 
Purpose Separator can also be used as a 
regular Cream Separator to produce cream 
testing as high as 55 per cent butterfat, and 
the bowl can be quickly adjusted by means of 
regulating screws lo produce cream of any 
desired richness. 
Styles, Sizes and Capacities. De Laval 
Multi-Purpose Separators can be provided in 
the new World’s Standard and Electro Series.
