PROVISIONAL SPECIFICATION.
Improved Apparatus for Boiling Sugar and Glucose, either Separately
or Mixed.
1, EDWARD SHAW, of 6, Cornwallis Crescent, Clifton, Bristol, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to boiling sugar which has been previously
dissolved in water to fit it for use in the manufacture of sweetmeats and
other uses.
With the sugar may or may not be mixed glucose, according to the character or
quality which it is desired that the product shall possess.
This invention consists in improvements in apparatus for carrying out the above
mentioned process.
According to this invention a series of closed pots or like receptacles are arranged
within a closed vessel charged with heated air, steam or other suitable heating
agent. Communication throughout the series of pots is established by pipes, the
outlet orifice of cach vessel being towards the bottom, and the inlets towards the
top. The liquid to be boiled is fed into one of the vessels, under pressure, by
pumping or otherwise, and together with the steam generated passes to the pot next
in succession. Similarly, for each pot, until the last of the series is reached whence
the cooked sugar is discharged. By the provision of expansion chambers, such as
the said pots, or their equivalents, placed at intervals in the path taken by the
liquid, the tendency of the steam to drive the liquid is checked to an extent which
ensures proper cooking or boiling of the liquid.
Further means for relief of steam pressure consist in the adoption of steam ducts
extending from each pot to any other in the series.
By the use of the above described apparatus the liquid is, as aforesaid, more
thoroughly boiled and a
more complete separation of sugar from steam is
effected.
Under a modification, the expansion chambers may, instead of being separately
made, consist of enlargements in the pipe through which the liquid and steam
flow.

3, EDWARD SHAW, of 6, Cornwallis Crescent, Clifton, Bristol, Engineer, 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 has reference to boiling sugar which has been previously

page_text: dissolved in water to fit it for use in the manufacture or sweetmeats and for like
and analogous purposes.
With the sugar may or may not be mixed glucose, according to the character or
quality which it is desired that the product shall possess.
This invention consists in improvements in apparatus for carrying out the said
process.
According to this invention a series of closed pots or like receptacles are arranged
within a closed vessel charged with heated air, steam or other suitable heating
agent. Communication throughout the series of pots is established by pipes, the.
outlet orifice of each vessel being towards the bottom, and the inlet towards the
top. The liquid to be boiled is fed into one of the vessels, under pressure, by
pumping or otherwise, and together with the steam generated passes to the pot next
in succession. Similarly, for each pot, until the last of the series is reached whence
the cooked sugar is discharged. By the provision of expansion chambers, such as
the said pots, or their equivalents, placed at intervals in the path taken by the
liquid, the tendency of the steam to drive the liquid is checked to an extent which
ensures proper cooking or boiling of the liquid.
Further means for relief of steam pressure consist in the adoption of steam ducts
extending from each pot to any other in the series.
By the use of the above described apparatus the liquid is, as aforesaid, more
thoroughly boiled and a more complete separation of sugar from steam
effected.

Under a modification, the expansion chambers may, instead of being separately
made, consist of enlargements in the pipe through which the liquid and steam
flow.
Referring to the accompanying sheet of illustrative drawings,
"
Fig. represents, partly in section, and partly in elevation, apparatus constructed
and arranged, in accordance with this invention, for boiling or " cooking sugar
and glucose, either separately or mixed so as to fit the same for use in the manu-
facture of sweetmeats and the like. Fig. 2 is a plan of Fig. 1, the cover of the
vessel a being removed. Fig. 3 represents a section at an enlarged scale of one of
the pots b. Within the vessel a, which is charged with steam, hot air or other
suitable heating agent, is contained a series of closed pots communication throughout
which is established by pipes c for the flow of syrup and by steam ducts d
for conducting steam throughout the series as hereinafter more particularly
described.
The provision of the ducts d is optional. The outlet from each pipe c is towards
the bottom of each pot b, and the inlet towards the top. The outlets and inlets of
the steam ducts d are towards the top of each pot b.
The syrup is forced by pumping or otherwise into the uppermost of the pots b
through the inlet & and after passing through the whole series is discharged cooked
at the outlet 6%. e is the inlet for charging the vessel a with steam, hot air or other
suitable heating agent by which the syrup is boiled or "cooked." e¹ is the outlet
for the heating agent. The pots serve as expansion chambers for the steam
generated in boiling the syrup and also as temporary checks in the flow of the syrup
which is accordingly not driven forward by the action of the steam so rapidly as
would, in the absence of the pots b, be the case. To enhance this effect the steam
ducts d are provided, by which provision is made for more free escape of the surplus
steam, and undue velocity of the flow of syrup is obviated.
At Fig. 4 is illustrated a modification according to which the pipe fin which the
syrup and steam are confined is altered in diameter at intervals. Fig. 5 is a plan
of Fig. 4 with the cover removed. Fig. 6 is an enlarged section of a portion of the
pipe. The larger portions of the pipe f serve as expansion and separating
chambers, in which the flow of the syrup is checked and thus the syrup is main-
tained for a longer time than would otherwise be so in contact with the heating
surface of the pipe f. The heating vessel a and parts appertaining thereto are

page_text: similar to the corresponding parts hereinbefore referred to in relation to the
arrangement shown at Figs. 1 to 3 inclusive.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In apparatus for boiling or cooking sugar and glucose either separately or
mixed to fit the syrup for use in the manufacture of sweetmeats and the like, in
which the syrup is forced through a pipe externally heated, means for preventing
unduly rapid passage of the syrup through the boiling or cooking apparatus; said
means consisting of a series of pots such as 6 placed at intervals in the externally-
heated pipe through which the syrup passes, the pots and pipe being contained
within a vessel such as a charged with steam, hot air or other suitable heating
agent; the arrangement being such that the flow of the syrup is temporarily
arrested in the said pots and flows from one to the other throughout the
series under the pressure of steam and not in virtue of previously acquired
velocity.
2. The provision of the steam ducts d whereby the difference in pressure between
two consecutive pots is reduced so that the speed at which the syrup passes from
one pot into the next section of the syrup pipe is kept at a rate which ensures
proper boiling or cooking.
3. The modification under which the pipe for the passage of the syrup and steam
is altered in diameter at intervals so that the heating surface of the pipe is more
fully utilized and the steam prevented from exerting an unduly powerful ejecting
force on the syrup, substantially as hereinbefore described with reference to
Figs. 4 to 6, inclusive, of the accompanying sheet of drawings.
