Improvements in and relating to the Treating and Aërating
of Milk.
-
1, JOHN GRAY, of 67 George Street, Stranraer, Wigtownshire, Manufacturer
of Dairy Utensils, do hereby declare the nature of my invention to be as follows:-
This invention has reference to an improved method of treating and aërating
milk for the purpose of eliminating all taints and odours from it.
According to my invention the milk, preferably as it comes from the cows, is
taken and spread on to the top of a vertical screen over the surfaces of which it
flows by gravity and gets broken up to run in the thinnest possible fibre and get
aerated, and have all taints and odours consequently removed.
In carrying my improvements into practice I preferably take a screen of wire
cloth of corrugated shape, and mount or secure same vertically between two upright
supports. A hopper or other receptacle with perforated bottom would be mounted
at the top of the upright frame or stand, into which the milk would be placed.
The milk as it passed through the perforations would preferably first drop on to
the surface of a tube or rod set horizontally from whence it would flow on to the
meshed wire cloth screen, and by gravity pass down this and be received in a
suitable vessel placed below the screen. The milk in travelling will thus get
broken up and run in the thinnest possible films or fibre over the wires and spaces,
so that every particle of the milk gets aërated and treated.
Instead of wires, tubes or perforated plates, either plain or corrugated may be
used; and the screen may be made of spherical, cylindrical conoidal oval or any
convenient shape or material suitable for giving the milk a vertical or angular flow
to get broken up or diffused and aërated.

Improvements in and relating to the Treating and Aërating
of Milk.
I, JOHN GRAY of 67 George Street, Stranraer, Wigtonshire, Manufacturer of
Dairy Utensils do hereby declare the nature of my invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement in writing, that to say :-
My invention has reference to an improved method of treating and aerating milk
for the purpose of eliminating all taints and odors from it.
According to my invention the milk, preferably as it comes from the cows, is
caused to flow down by gravity over the surface of a vertical screen and get broken
up so as to run in the thinnest possible fibre and get aerated, and have all taints
and odors cousequently removed. And in order that my invention may be properly
understood I have hereunto appended an explanatory sheet of drawings, reference
being made to the letters and figures marked thereon.

page_text: Referring to these drawings the aerating appliance to be described is portably
suspended from brackets a on a frame A preferably of wood consisting of side
standards A stayed together and fitted with a shelf or small platform A³ at top to
receive the vessel B from which the milk is run.
In carrying my improvements into practice I mount or secure a screen C of wire
cloth, either plain as shown in Figure 1, or corrugated as in Figure 2, vertically
between two upright supports C'. A hopper or gutter shaped receptacle C with a
line of perforations c along the centre of the bottom is secured between the tops of
the upright supports C' into which the milk is run from the vessel B. The milk as
it passes through the perforations c first drops on to the surface of a horizontal tube
or rod c² secured along the top of the screen C whence it flows on to and down the
meshes of the wire cloth screen C by gravity and is received into a gutter shaped
or other suitable vessel D portably suspended below the screen and whence it is
conveyed to any suitable receptacle through the discharging nozzle D'. The milk
in travelling down thus gets broken up and runs in the thinnest possible of films or
fibre over the wires and spaces, so that every particle of the milk gets aerated and
treated.
Instead of wires as shown in Figures 1 and 2, perforated plates as indicated in
Figure 3 either plain or corrugated, or tubes may be used, and the screen may be
made of any convenient shape or material suitable for giving the milk a vertical or
angular flow to get broken up or diffused and aerated.
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 :-
:-
First. An appliance for aerating milk constructed and arranged all substantially
as herein described and illustrated by the accompanying drawings.
Second. In an appliance for aerating milk the use of a hanging screen of wire
cloth, a perforated plate, or other equivalent material, either plain or corrugated, all
substantially as and for the purposes herein described and illustrated by the
accompanying drawings.
