PROVISIONAL SPECIFICATION.
Improvements in Boiling and Concentrating Apparatus.
THOMAS MOORE 27 Coldridge Road Eastville Bristol in the County of
Gloucester Engineer do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the making of an apparatus for boiling and
concentrating solutions of sugar and sugar with other ingredients also glucose
and with other ingredients also gums mucilages farinaceous gelatinous and
albuminous solutions and the like by superheated steam.
It consists of an ordinary boiler or water tube boiler and superheater of any
kind, or a special one to be described hereinafter. Or it may consist of a super-
heater only together with any feed arrangement, or a special one to be described
hereinafter. Also one or more boiling vessels.
In order to preserve the steam at any required temperature I prefer to pass it
through a superheater or regulator of the following construction:-
A number of tubes for steam to pass through are fitted into a vessel, and pass
through any suitable material for conveying heat to the tubes. I prefer to use
a metal or composite metal the melting point of which shall be under the temperature,
the steam is to be heated to.
These tubes may be straight or coiled or of any suitable form. These tubes may
be so arranged that the steam may pass through them and into the space between
the melted or dissolved material for heating and the top of the vessel or the tubes
may pass into another compartment above the top of the compartment holding the
melted or dissolved material.
When using the superheater only or superheater with water tube boiler I prefer
to use the following feed arrangement :-
A water vessel is connected top and bottom with the superheater or water tube
boiler so that the water may be let into them by gravitation by a suitable tap or
valve arrangement to admit steam so that the pressure would be equal on both sides.
This may be used with an ordinary boiler.
The superheated steam may be passed through a coil in the solution or blown
direct into the solution until it is brought to the required temperature or consistency.
This method has the following drawback, that is, the steam in the superheater or
on entering causes a back pressure which prevents the steam from passing through
sufficiently rapid. This may be overcome by drawing or sucking the steam through
the coil or solution either by a condenser or pump.
This method of boiling permits the use of wooden casks with or without metal
lining for boiling and dissolving vessels.
In making candy or boiled sugar I prefer to boil the solution to a certain
consistency by passing steam through a coil in the boiling vessel, and to finish it by
drawing the superheated steam through the solution as already described.

THOMAS MOORE 27 Coldridge Road Eastville Bristol in the County of
Gloucester 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 for its object the making of an apparatus for boiling and
concentrating solutions of sugar and sugar with other ingredients; also glucose and
with other ingredients also gums, farinaceous, gelatinous and albuminous solutions
and the like by superheated steam.
In the accompanying drawings
Fig. 1 shows arrangement of boiler superheater and melting and boiling pans.
Fig. 2 shows waterfeed system with boiling pan and pump.
Fig. 3 shows an alternative condensing arrangenient.
Fig. 4 shows an arrangement for moveable firebox.
In Fig. 1, a is an ordinary boiler supplying steam to the superheater b. This
superheater may consist of one or more coils of pipe or any other suitable arrange-
ment, placed over a fire through which steam may be passed.
The superheated steam is conducted through the coils d and jacket e of boiling
pan n or into the material in the boiling pan as at f. Figs. 2 and 3. The super-
heated steam may be conducted from the jacket or coil of the boiling pan to the
jacket or coil of the melting pan so that the heat it still contains may be utilized.
Fig. 2 shows an alternative arrangement for dispensing with the boiler and
making the superheater combined with a special waterfeed answer the purpose.
The tank is filled with water by opening the air valve and the water supply
valve on pipe until water runs through 7; both and are then closed and m
and n opened, m being regulated so as to supply the water in quantity as required.
There may be a water gange to this ve--el.
The water on reaching the first portion of the superheater is vaporized and
superheated in the other portion. It will now be understood that the pressure
produced is equal at both the top and bottom of the water in, the water will
therefore descend by previtation. The superhertelsteem then itilized as before
explained.
When the system is used for delivering superheated steam into the ingterial,
I cover the boiling panin airtight as represented in Figs. 2 and 3, and either
attach a pamp
Fi to draw the superheated
steam through the metal and remove theme together with the steam produced
from the material by the superheat from the superheated steam. This arrangement
is necessary when using steam of very low pressure, which gives a greater proportion
of heat to the amount of moisture. If superheated steam of high pressure is used
this arrangement is not so necessary.
I prefer to make the firebox under the superheater moveable by placing
firebox a, on slide bars as shown in Fig. 4; and having a supplementary
chimney g with damper under which the firebox may be drawn when the coil is
not in use, in order to preserve the coil as much as possible.
I may make any combination of any part of each system described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner it is to be performel, I declare that what I claim is :—
1st. The use of superheated steam for hoiling and concentrating solutions of
sugar, and sugar with we hire e
J
and with other ingredients,

page_text: also gums, farinaceous, gelatinous and albuminous solutions substantially as
described.
2nd. The use of the water feed with superheater for producing superheated steam
for boiling any of the above named solutions and the like, substantially as
described.
3rd. The boiling of the said solutions by sucking or drawing the superheated
steam through the said solutions substantially as described.
4th. The superheater with moveable firebox for the purpose of boiling the above
named solutions substantially as described.
5th. The combination of the water feed and superheater with jacketed pan or
coil.
6th. The combination of waterfeed and superheater with jacketed pan and coil
with the pump or condenser or both.
7th. The combination of ordinary boiler with superheater and jacketed pan or
coil and with pump or condenser or both.
8th. Also any other combination of any of the seperately described parts or
systems which may be made.
Dated this 2nd day of October 1895.
