Improvements in the Treatment of Staroh or Starchy Matter," or
Crystallizable Sugar, for the Obtainment therefrom of Products
more especially suitable for Use in Brewing.
I, HUNGERFORD COLSTON EARDLEY WILMOT of 9 Oxford and Cambridge
Mansions in the County of London Gentleman do 'hereby declare the nature of
this invention to 'be as follows :
"
My invention relates to the treatment of starch or starchy matter or crystallisable
sugar for the obtainment therefrom of products; suitable for use in brewing or for
other purposes.
The conversion of starch or starchy matter into dextrine or soluble products, has
been effected by the action of sulphuric or other acid this necessitating the use of
either a free or carbonated alkali to neutralize the acid when the desired change
has been effected. This method of manipulation besides being troublesome
entails loss of time and material and introduces matters which are sometimes
objectionable.
My invention avoids these objections and consists in passing carbon-dioxide with
or without steam into and through a mixture of starch or starchy matter or
crystallizable sugar. with water heated in a suitable vessel to a temperature of or
above boiling point. The passage of the carbon, dioxide or of carbon dioxide and
steam into, and through the heated mixture of starch or starchy matter and water
or crystallizable sugar and water is continued under such pressure as may be
necessary in accordance with the materials under treatment until the desired
change is brought about which may be ascertained by well known. tests. The
conversion being accomplished the supply of the carbon-dioxide, or, carbon-dioxide
and steam is discontinued and the vessel and contents relieved from pressure and
the matters operated upon are ready for use after filtration or settlement as when
pressure is relieved the gas being volatile escapes freely and no material is requisite
for purposes of neutralization.
The most convenient method of storing, the carbon-dioxide is to collect it in a
suitable vessel by means of a suction and pressure pump from the source, of i its
production taking it from this receptacle as required, by means of a cock and pipe,
so arranged when steam is used that the gas can be made to mix with the steam as
it passes into the vessel containing the matter to be operated upon. I may also
provide means of heating the gas before mixing with the steam so as to prevent
condensation of the steam aud to render the mixture, more effective for the
purposo.

I, HUNGERFORD COLSTON EARDLEY WILMOT of 9, Oxford and Cambridge
Mansions in the County of London, Gentleman, do hereby declare the nature of
my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention relates to the treatment of starch or starchy matter or crystallizable
sugar for the obtainment therefrom of products (dextrine, or dextrose, or lovulose)
suitable for use in brewing or for other purposes. The conversion of starch, or
starchy matter, into such soluble products has hitherto been effected by the action
of sulphuric, or other acid, in a liquid form, thus necessitating the use of either a
free or carbonated' alkali to neutralize the acid' when the desired change has been
effected. This method of manipulation, besides being troublesome entails loss of
time and material and introduces matters which are sometimes objectionable. My
invention avoids these objections and consists in passing carbon-dioxide with or
without steam into and through a mixture of starch or starchy matter or
crystallizable sugar with water heated in a suitable vessel to a temperature of,
or above boiling point, instead of using sulphuric acid, or other acid in a liquid
forin. The passage of the carbon dioxide, or of carbon dioxide and steam into the
heated mixture of starch, or starchy matter, and water or crystallizable sugar and
water, is continued under pressure in accordance with the materials under treatment
until the desired' change is brought about which may be ascertained by well known
tests. The conversion being accomplished the supply of the carbon-dioxide or
carbon-dioxide and steam is discontinued and the vessel and contents are then
relieved from pressure and the matters operated upon are (after filtration or
settlement of residual matters) ready for use as when pressure is relieved the
carbon dioxide escapes freely and no material is requisite for purposes of
neutralization.
The most convenient method of storing the carbon-dioxide is to collect it in a'
suitable vessel by means of a suction and pressure pump from the source of its
production taking it from this receptacle as required by means of a cock and pipe
so arranged when steam is used that the gas can be made to mix with the steam as
it passes into the vessel containing the matter to be operated upon. 1 may also
provide means for heating the gas before, or after, mixing with the steam, so as to
prevent condensation of the steam and to render the mixture of carbon dioxide and
steam more effective for the purpose.
The accompanying drawing represents apparatus suited for carrying my invention
into effect but I do not limit myself to the use of such apparatus.
b
A is a vessel which can be tightly closed: It is provided with an inlet at a for
the water and the starch or starchy matter, or for the crystallizable sugar, to be
treated, and with outlets a2 and a for the treated matter aud residual matter.
Through a suitable stuffing box and bearings carried by the said vessel. A passes a
tubular shaft B provided with tubular perforated arms & carrying paddles &³. The
said shaft is driven by any suitable motor through a worm c and a worm wheel
mounted on the said shaft. A pipe D communicates with the said shaft B the
said pipe being so connected by a joint d' as to allow of the rotation of the shaft.
The said pipe D is formed with or connected to a coil d in a furnace, or heating
apparatus E. The pipe de leads from the coil to a forcing device, or pump, F by
which carbon-dioxide is drawn through the pipe g from any suitable source and
forced through the pipes and hollow shafts and arms into the vessel A through the

page_text: perforations in the said arms. The contents of the vessel A may be heated in any
desired manner.
I have shewn for this purpose the steam pipe which com-
municated with the pipe so that steam and carbon dioxide pass through the
coil d and are superheated therein on their way to the vessel A. i is a catch box
provided with a valve by which any water of condensation can be withdrawn.
The carbon dioxide can be collected direct from fermenting vessels in breweries, or
from kilns, or any other suitable source, or it may be collected and stored under
pressure for use in the process.
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. The production of soluble products for use in brewing or for other purpose
from starch or starchy matters by the use of carbon-dioxide (CO,) or carbon-
dioxide and steam substantially as hereinbefore described.
2. The production of directly fermentable products for use in brewing or for
other purpose from crystallizable sugar by the use of carbon-dioxide (ČO,) or
carbon dioxide and steam substantially as hereinbefore described.
