Improvements relating to the Purification of Fatty Substances and
to Apparatus therefor.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the purification of fatty substances and to apparatus
therefor.
The difficulties experienced in the purification of fatty substances extracted by
means of volatile solvents arise from the intimate union between the molecules of the
solvent and the fatty substance so that their solution having reached a certain degree
of concentration, forms as it were, a uniform whole, the disassociation of which can
only be effected by special means. For the purpose of separating these two substances
which as so intimately combined, I cause their concentrated solution to be projected
in the form of as fine a spray as possible into an atmosphere of steam and in a partial
vacuum so as to bring the smallest particles of the mixture into contact therewith in
order to act in the most efficaceous manner possible.
The apparatus which I use for this purpose and which can be constructed in various
forms, comprises a cylindrical boiler provided with a double bottom the interior space
of which is designed for steam obtained from any generator. At the upper part of
the boiler is arranged a pipe which terminates in a horizontal distributing coil pierced
with as great a number of small holes as possible through which the solution to be
disassociated is caused to escape in the form of fine spray. A pipe connected with
the upper part of the boiler sets the latter in communication with a pump for producing
a vacuum through the medium of a refrigerating coil.
The aforesaid pump is set in motion and when the desired barometric depression
has been obtained, a quantity of water, which is determined according to the require-
ments in each case and regulated by the nature of the solution and the quantity to be
purified, is allowed to enter through the pipe. Steam from a generator is introduced
into the double bottom. When the temperature which is suitable for the solution
under treatment is obtained, the latter is caused to enter the boiler through the afore-
said distributing coil. In contact with the steam and in this partial vacuum the
solution will be disassociated and the solvent which is drawn by the pump through
the said refrigerating coil will be completely eliminated from the fatty substance
which collects purified at the bottom of the boiler.

Improvements relating to the Purification of Fatty Substances and
to Apparatus therefor.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex 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 :-
This invention relates to the purification of fatty substances and to apparatus
therefor

page_text: The difficulties experienced in the purification of fatty substances extracted by
means of volatile solvents arise from the intimate union between the molecules of
the solvent and of the fatty, substance so that their solution, having reached a
certain degree of concentration, forms as it were a uniform whole the disassociation
of which can only be effected by special means. For the purpose of separating
these two substances which are so intimately combined, I cause their concentrated
solution to be projected in the form of as fine a spray as possible into an atmo-
sphere of steam and in a partial vacuum so as to bring the smallest particles of
the mixture into contact therewith in order to act in the most efficaceous manner
possible.
One form of apparatus which I use for this purpose, is illustrated in the
acompanying drawing the said apparatus can however he constructed in various other
forms.
It comprises a cylindrical boiler A provided with a double boitom B the interior
space of which is designed for steam obtained from any generator.
At the upper
part of the boiler is arranged a pipe C which terminates in a horizontal distributing
coil 1 pierced with as great a number of small holes as possible through which the
solution to be disassociated is caused to escape in the form of fine spray. A pipe E
connected with the upper part of the boiler sets the latter in communication with
a pump G for producing a vacuum through the medium of a refrigerating coil F.
The operation is as follows. The aforesaid pump G is set in motion; and when the
desired barometric depression has been obtained, a quantity of water, which is
determined according to the requirements in each case and regulated by the
nature of the solution and the quantity to be purified, is allowed to enter through
the pipe H. Steam from a generator is introduced into the double bottom B.
When the temperature which is suitable for the solution under treatment is obtained,
the latter is caused to enter the boiler through the aforesaid distributing coil D.
In contact with the steam and in this partial vacuum the solution will be dis-
associated, and the solvent which is drawn by the pump G through the said
refrigerating coil F will be completely eliminated from the fatty substance which
collects purified at the bottom of the boiler.
