Improvements in Cooling Apparatus Combined with Centrifugal
Milk Separators.
'
I, ERIK GUSTAF NICOLAUS SALENIUS, of Albano, in the Kingdom of Sweden,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The invention relates to a cooling apparatus in combination with centrifugal
milk separators in order to reduce the consumption of ice. The arrangement
consists in placing the cream cooler in communication with another cooler by
means of which the sterilized milk is cooled before being conducted into the separator,
the same cooling liquid thus being used for cooling the cream in the first place
and afterwards the sterilized milk.
In the accompanying drawings,
Figure 1 is a diagrammatical view of the improved apparatus.
Figure 2 is a vertical longitudinal section of the milk cooler.
Figure 3 is a transverse section of the same and
Figure 4 is a plan thereof partly in section.
a designates the reservoir of the cooling liquid, b the cream cooler, c'the
centrifugal separator, d the milk cooler and e the container for the sterilized milk.
The cream
or the skim-milk is conducted from the centrifugal separator
through the pipe f to the cooler b to which the cooling liquid is conducted from the
reservoir a through the pipe g. On passing through the cooler 6 the cooling liquid
flows through the pipe to the cooler d, whence it is discharged through the
pipe i. From the container e the sterilized milk runs through the pipe k to the
The cooling
cooler d and then through the pipe to the centrifugal separator c.
liquid, after having passed through and cooled off the cream or skim-milk to
the desired temperature flows to the milk cooler d and cools off the comparatively
warmer milk coming from e. For utilizing the heat, absorbed by the cooling liquid
this may be employed for feeding the boiler or the like.
An efficient arrangement of the cooler d is shown in Figures 2, 3 and 4.
The cooler consists of three horizontal cylinders, m, n, o, arranged one within
The
the other with spaces p and q between the cylinders, as shown in Figure 2.
cooling liquid is distributed to the two cylinders m and o, for instance by being
allowed to descend from a vessel r. provided with two outlets s and t, into the
respective inlets u and v of the two cylinders and to discharge through the united
pipes
x and Y, while the milk is made to enter between the cylinders through the
pipe and to pass off through the pipe l. Thus the milk is spread out in a thin
ГР.

metal wall only. It is evident that a cooler of the kind just described may also
be employed for cooling the cream or the skim-milk, although a different con-
struction is shown in the drawing, and that the cylinders may be replaced by
vessels of another shape.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is :-
1. A cooling arrangement in combination with a centrifugal milk separator,
characterized thereby that the cooler (b) for the cream or skim-milk issuing from
the separator, is placed in such communication with the cooler (d) for the warm
milk which is to be conducted into said separator that the cooling liquid will pass
from the former cooler (6) into the latter cooler (d) in order that the cooling
liquid may be better utilized.
2. The arrangement of the cooler, mentioned in Claim 1 for cooling the milk or
the cream, consisting of three cylinders (m, n, o) or metal vessels of other shape
arranged one within the other with spaces between, one of said spaces (p) being
occupied by cooling liquid and the other (g) by the milk or cream, while the inner
cylinder is filled with cooling liquid.
