Improvements in connection with Apparatus for Utilizing the Heat
Abstracted in Cooling Milk and other Liquids.
I, LOFTUS ANTHONY BRYAN, of Borrmount Manor, Enniscorthy, in the County
of Wexford, Ireland, a Captain in the Waterford Artillery Militia, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is so to construct cooling apparatus that the heat
abstracted from the hot milk or other liquid during the cooling process is utilized
to heat the new milk or other liquid passing to the pasteurizing, sterilizing or
other heating apparatus. A further object of the invention is to fit the parts
together in such a manner that they can be readily removed for cleaning purposes
when required.
According to this invention the cooling apparatus is made in the form of a
truncated cone having a continuous spiral path formed externally thereupon.
The outer wall of this spiral path is formed by a conical partition making a joint
with the spirals and provided at the bottom with india rubber air tubes or other
suitable packing. Outside this conical partition is arranged another cone section,
or conico cylindrical section with its interior con-shaped, and furnished with a
spiral path making a joint with the conical partition aforementioned. Both
spiral ways are furnished with suitable inlets and outlets. The milk or other
liquid is allowed to flow along the spiral path of one of the cones from the top to
bottom or vice versa and the liquid to be heated is passed in the opposite direction
along the spiral path of the other cone, the heat abstracted from the hot liquid
passing by conduction through the conical partition to the liquid to be heated on
the other side thereof.

Improvements in connection with Apparatus for Utilizing the Heat
Abstracted in Cooling Milk and other Liquids.
I, LOFTUS ANTHONY BRYAN, of Borrmount Manor, Enniscorthy, in the County
of Wexford, Ireland, a Captain in the Waterford Artillery Militia, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement;-
The object of this invention is so to construct cooling apparatus that the heat
abstracted from the hot milk and other liquid during the cooling process is

lizing or other heating apparatus. A further object of the invention is to fit the
parts together in such manner that they can be readily removed for cleaning
purposes when required.
In the accompanying drawings Fig. 1 is a vertical section of my apparatus,
Fig. 2 is a vertical section of a modification thereof and Fig. 3 is a plan of Fig. 2.
The same parts are lettered to correspond in the three figures.
The form of apparatus shown in Fig. 1 is made in the form of a truncated
cone A having a continuous spiral path B formed externally thereupon. The
outer wall of this spiral path is formed by a conical partition C making a joint
by simple contact with the edges of the spirals B and provided at the bottom with
india rubber air tubes D or other suitable packing. Outside this conical par-
tition C is arranged another cone section E or conico-cylindrical section with a
spiral path F formed thereupon so as to make a joint by simple contact with the
partition C aforementioned. Both spiral ways are furnished with suitable inlets
and outlets. The inlets for the ways B and F are marked with the letters b and f
respectively and the corresponding outlets are marked with the letters b¹ and fi.
The milk or other liquid is allowed to flow along the spiral path of one of the
cones from top to bottom or vice versa and the liquid to be heated is passed in
the opposite direction along the spiral path of the other cone, the heat abstracted
from the hot liquid passing by conduction through the conical partition C to the
liquid to be heated on the other side thereof.
In Fig. 1 the hot milk or other liquid enters at f and leaves at f¹ while the
cold liquid enters at 6 and leaves at 61 in a warm state having abstracted heat by
its passage over the conical partition C.
It will be seen that by deflating the air tubes D or otherwise removing the
packing the apparatus is readily separable into three main parts, viz:-(1) the
inner truncated cone A with the spiral way B fixed thereto; (2) the conical
partition C; and (3) the outer section E with the spiral way F fixed thereto.
The parts where they fit together are made conical so as to secure a tight joint
by contact when fitted together and also to allow of adjustment when worn.
The modification shown in Fig. 2 and 3 differs only from that already described
in having a way on the inside and another on the outside of the spiral, so that
the spiral itself forms the partition.
In this form the apparatus consists of the inner cone A. the spiral partition C
and the outer plate E, the three parts being separated from each other and making
joints by simple contact. The hot liquid is admitted to the trough G secured to
the upper end of the outer plates E and flows down between said plate E and the
outside of the spiral partition C₁ and out by the outlet H while the cold liquid is
admitted at J between the inner cone A and the inside of the spiral partition C¹
flows between them and passes off through the outlet K to the separator or other
apparatus.
M
Where it is found that the entering milk is not sufficiently hot it may be
further heated by a steam pipe such as is shown in Fig. 2 which passes up through
the interior of the hollow cone A and discharges in the upper part thereof.
is a diaphragm partition in cone A which serves to keep the upper part as a
heating chamber N and is a drain pipe leading off the steam condensed in said
chamber.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
(1) Apparatus for effecting an interchange of heat between liquids comprising
an inner section with an external spiral way thereon having an inlet and an outlet
a conical partition, and an outer section with an internal spiral way thereon,
having an inlet and an outlet the parts being combined to operate substantially
as described with reference to Fig. 1 of the accompanying drawings.

page_text: (2) Apparatus for effecting an interchange of heat between liquids comprising
an inner section a spiral partition and an outer section with inlets and outlets
whereby the liquids are admitted to opposite sides of the spiral partition sub-
stantially as described with reference to Figs. 2 and 3 of the accompanying
drawings.
(3) Apparatus for effecting an interchange of heat between liquids comprising
inner and outer sections, a conical partition and spiral ways and inlets and outlets
whereby the liquids are admitted to flow on opposite sides of said partition sub-
stantially as described.
