PROVISIONAL SPECIFICATION.
An Improved Preparation of Peptonised Milk and Cocoa.
We WALTER HENRY THEW of No. 9 Arundel Street in the City of West-
minster Managing Director to the Condensed Peptonised Milk Company (Limited)
of tho Town and County of Buckingham and JOHN HENRY HOOKER of the
Town and County of Buckingham Manager to the said Company do hereby
declare the nature of this invention to be as follows:-
-
The object of this invention is the production of a preparation of peptonised
milk and cocoa in the form of powder and solid blocks or cakes.
According to the said invention a quantity of a moist mixture of peptonised
milk and cocon or of peptonised milk and cocoa and sugar manufactured as
described in the Specification of Letters Patent No. 14965 dated 11 October 1884
and granted to Waltor Henry Thew (one of the present applicants) is placed in
shallow pans or other suitable apparatus heated by means of hot water for the
purpose of driving off moisture from the said mixture. While the said mixture is
being acted on by the heat it is broken up by means of wooden instruments or
other suitable appliances and when sufficiently dried it is removed and reduced
to powder by crushing or grinding. Where the mixture is required to be in the
form of blocks or cakes the powder is placed in moulds of the shape requirol for
the blocks or cakes and subjected to pressure sufficient to produce cohesion of the
particles of the dried mixture.

An Improved Preparation of Peptonised Milk and Cocoa.
We WALTER HENRY THEW of No. 9 Arundel Street in the City of West-
minster Managing Director to the Condensed Peptonized Milk Company (Limited)
of the Town and County of Buckingham and JOHN HENRY HOOKER of the Town
und County of Buckingham Mauager to the said Company 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 object of this invention is the production of a preparation of peptonized
milk and cocoa in the form of powder and solid blocks or cakes.
According to the said invention a quantity of a moist mixture of poptonized milk
and cocoa or of peptonized milk and cocoa and sugar manufactured as described in
the Specification of Letters Patent No. 14965 dated 11 October 1884 and granted
to Walter Henry Thew (one of the present applicants) is placed in shallow pang
or other suitable apparatus heated by means of hot water for the purpose of
driving off moisture, from the said mixture. While the said mixture is being acted
on by the heat it is operated on by means of wooden instruments or other suitable
appliances and when sufficiently dried it is removed and reduced to powder by
crushing or grinding.
A convenient form of apparatus suitable for use in drying the mixture consists

page_text: of a shallow pan or tray which may be formed of sheet iron or copper and tinned
or enamelled on the inner side or of glass or earthenware under the whole of the
bottom of which pan or tray is formed or secured a shallow chamber or vessel for
containing water below which is a box or jacket for receiving steam by means of
which the water in the water vessel is heated as required. The said water
vessel is suitably fitted to admit of introduction and removal of water and
to admit of the temperature of the water being ascertained and suitable
provision is made for supply of steam to and escape of water of condensation
from the steam jacket. When the water vessel is charged with water and steam
is admitted to the steam jacket heat from the steam is absorbed by the water
in the said vessel and communicated by it to the pan or tray above it in or
on which pan or tray the mixture to be dried is placed. A suitable temperature
for the water in the water vessel is from about 45 degrees Centigrade to about
55 degrees Centigrade. The drying of the mixture when in the pan is expedited
by spreading the said mixture over the bottom of the pan and occasionally
collecting and re-spreading it until it is too dry to spread when it is broken up the
pieces being kept in motion and further broken as the moisture from them
evaporates. When the pieces crumble under pressure the drying of the mixture
has been carried far enough and it may be removed from the apparatus. Wooden
spatulas are preferred for use in operating as hereinbefore described on the
mixture in the pan but spatulas or other convenient instruments of any metal or
material which will not produce any objectionable chemical action on or impart
any objectionable flavour to the mixture while in a moist state may be used. The
drying operation is by preference conducted in a room heated to a temperature
of about 21 degrees Centigrade in order that the moisture driven off from the
mixture in the drying pan may be quickly absorbed by the atmosphere.
A convenient form of apparatus for use in reducing the mixture to powder after
the drying operation is completed consists of granite rollers suitably mounted with
their peripheries or curved faces nearly in contact and capable of being caused to
rotate towards each other by means of suitable gearing to which motion is com-
municated either by hand or by means of any convenient motor. The said
apparatus is furnished with a hopper into which the dried mixture to be reduced
is fed as required and whence it passes to the said rollers whereby it is crushed
when the apparatus is in action. The said apparatus is also furnished with a
receiver into which the mixture passes after being acted on by the said rollers.
After the dried mixture has been thus crushed or reduced to a coarse powder it
is ready for use and until required for use it should be placed in vessels of metal
or glass or glazed earthenware which should then be so closed or scaled as to
prevent access of air to their contents.
Where the product is required to be in the form of blocks or cakes moulds of
the shape required for the blocks or cakes are heated to the degree necessary to
melt or soften the fat naturally contained in the constituents of the moist mixture
bereinbefore referred to and a quantity of tho dried and powdered mixture is
placed in the said mould and subjected to sufficient pressure to produce cohesion
of the particles of the said mixture. A screw press or a press of any other kind
by means of which sufficient power may be exerted to cause the powder when
alightly warmed to take a solid form is suitable for the purpose.
Where a moist mixture of peptonized cocoa and milk is to be prepared specially
for treatment as herein described ordinary "cocoa block" which consists of ground
cocoa beans and contains the whole of the fat and other natural constituents thereof
may be substituted for the preparation of cocoa prescribed for use in the manu-
facture of the mixture described in the Specification of the Patent hereinbefore
referred to.
Where the dried product is designed for use as a sweetmeat or in making
beverages which are required to contain more sugar than is contained in the moist
mixture prepared as described in the aforesaid Specification sugar is added to the
said moist mixture before treating it as horein described.

page_text: Having now particularly described and ascertained the nature of the said inven--
tion and in what manner the same is to be performed we declare that what we
claim is :-
The manufacture or product herein before described which consists of a.
preparation in the form of powder or solid blocks or cakes composed of peptonized.
milk and cocoa or of peptonized milk and cocoa in admixture with sugar and is the
result of treatment of a moist mixture of such matters substantially as hereinbefore.
described.
