page_text: I, ANDRÉ OLIVIER, of No. 188, Rue Lafayette, Paris, in the Republic of France,
Employee, do hereby declare the nature of this invention to be as follows:-
Certain industries, breweries for example, employ glucose of a low standard or
degree of strength. In order to enable this glucose to be delivered in bulk it is
evaporated to about 40 to 42° Baume, while for use in these industries it has to be
again reduced to its original strength that is to say 18 or 20° Baume or even less.
Thus the result is that glucose in its primitive state obtained at 18 to 20° Baume
is evaporated to 42° Baume and then afterwards again reduced to its primitive state
of 18° Baume.
This mode of proceeding causes work to be done, such as the evaporation, filtra-
tion and so on, which is useless from the point of view of the final result.
Now this invention has for its object the devising of improved means for the
industrial application of the glucose whereby to avoid all the aforementioned use-
less operations and so effect great economy.
My invention is based on the principle of applying to the industries using
glucose of low density for fermenting purposes, the saccharification of amylaceous
substances with the object of obtaining the glucose direct of the strength required
for use.
By my improved process the manufacturer is able to choose the raw materials
for obtaining his glucose and also to use this latter at once on being produced.
This double result has the effect of yielding superior products owing to the quality
of the raw material and the immediate consumption thereof.
In order to enable my invention to be clearly understood and to be readily
carried into practice I will by way of example describe a process for the com-
mercial manufacture of glucose, such process being capable of application in any
industry requiring the use of glucose.
I mix in a trough a the amylaceous substances, such as fecula or starch, which it
is desired to convert into glucose, with a volume of water corresponding to the
strength required.
The fecula thus mixed with water is then saccharified in the ordinary manner in
an autoclave b. The autoclave is first fitted with a certain quantity of water to
which is then added sulphuric acid and finally steam is introduced through a pipe c
which is perforated so as to enable the steam to penetrate the middle of the liquid.

manufacture of glucose and which is used in conjunction with other apparatus as
used for the particular industry employing glucose.
I mix in a trough a the amylaceous substances, such as fecula or starch, it is
desired to convert into glucose, with a volume of water corresponding to the
strength required. The fecula thus mixed with water in then saccharified in the
ordinary manner in an autoclave b. The autoclave is first fitted with a certain
quantity of water to which is then added sulphuric acid and finally steam is
introduced through a pipe e which is perforated so as to enable the steam to pene-
trate the middle of the liquid. The fecula previously mixed with water in the
trough a is thereupon introduced into the autoclave and becomes promptly con-
verted into glucose within a few minutes.
When the entire quantity of fecula has been converted into glucose, that is to
say when the saccharification is completed the steam is shut off and the acid is
then saturated by any convenient means.
The liquid is next run into a filter press d when the glucose is freed from its
impurities, and for this purpose steam is allowed to enter at the upper portion
of the autoclave 6 through a pipe e and acts upon the surface of the liquid thus
forcing the latter through the pockets of the filter press.
By varying the proportions of water, acid, and fecula, the glucose is at once
obtained of the strength required for immediate consumption.
It is obvious that my invention can be applied with advantage in any industrial
undertaking where glucose of low density is required.
It should be understood that I reserve to myself the right to vary the form,
dimensions, and arrangements of details in connection with the apparatus herein
described to suit various circumstances.
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:
The improvement in the production of glucose of low density, such improve-
ment consisting in combining the saccharification of amylaceous substances with
industrial operations with the object of enabling the glucose to be obtained
directly at the strength required for immediate use, substantially as hereinbefore
described and for the purpose stated.
