LETTERS PATENT to George Lawrence of St Mary Axe in the County of
Middlesex for an Invention of IMPROVEMENTS IN THE TREATMENT OF
MILK AND MATTEINS
DE MIXED THEREWITH AND IN APPARATUS THEREFOR
PROVISIONAL SPECIFICATION left by the said George Lawrence at the
Office of the Commissioners of Patents on the 8th June 1883.
GEORGE LAWRENCE of St Mary Axe in the County of Middlesex, " IMPROVE-
MENTS IN THE TREATMENT OF MILK AND MATTERS TO BE MIXED THEREWITH
AND IN APPARATUS THEREFOR,"
"
The improvements relate to the treatment of milk by passing it through one or
more steam ejectors mingled with steam or other gases at an elevated temperature
thereby dividing the milk into particles and rendering it more capable of
receiving fatty and other ingredients for the purposes of enrichment or for other
purpose.
The apparatus consists of a steam ejector (similar in principle to a steam injector)
or a series thereof, around the nozzle or nozzles of which the milk to be treated
is passed also fatty and other ingredients in a fluid state, sometimes these
fatty and other ingredients may be led to the ejector or a series of ejectors by
separate pipes, or such ingredients may be blended with the milk before being
passed, the steam or gases acting on the milk and ingredients thoroughly
disintegrates the fatty or other matters and incorporates them with the milk or
other matters

GEORGE LAWRENCE, of St Mary Axe in the County of Middlesex,
" IMPROVE-
MENTS IN THE TREATMENT OF MILK AND MATTERS TO BE MIXED THEREWITH
AND IN APPARATUS THEREFOR,"
This invention consists in the treatment of milk by the improved mode of
breaking it up with fatty matters by passing it and them mingled with steam or
other gases at an elevated temperature through one or more steam ejectors
thereby dividing the milk into particles and rendering it more capable of receiving
the fatty or other ingredients which are also disintegrated by their passage and
thus by the admixture of the milk and fatty or other matters enriching or
otherwise treating such milk.
I have found the apparatus delineated in the drawing annexed very convenient
for carrying out my improved process. In said drawing Fig: 1 is a side or front
elevation and Fig 2 a plan view. Like letters refer to like or corresponding
parts. A is a steam ejector (similar in principle to a steam injector) one or more
of such may be used around the nozzle or nozzles of which the milk and fatty
or other matters are passed in a fluid state from the chambers E. F. G. which in
this case respectively hold milk, fat, and oil; these chambers are steam jacketted
for obtaining the necessary temperatures. The milk fatty and other ingredients
are led to the ejector A from the chambers by their respective outlet pipes B. C. D.
such outlet pipes being controlled by stop cocks as shown. Or the milk and
fatty or other ingredients may be mixed or agitated in one chamber and from
that chamber allowed to pass to the ejector direct. H is a steam inlet.
L supplementary steam or cold water inlet for regulating the temperature.
outlet for amalgamated material. The milk and. fatty or other matters being
forced through the ejector by its action are thoroughly amalgamated and thus
milk or cream can be enriched or antiseptically treated.
K is
CLAIM:
The process of treating milk with fatty and other matters, by passing it and
them mingled with gases through one or more steam ejectors for separating and
mixing the particles, substantially as described and for the purposes set forth.
In witness whereof I the said George Lawrence have hereunto set my hand
and scal this 8th day of December A.D. 1883.
