relating thereto.
A communication from abroad by Monsieur SALOM BENSAUDE,. of Paris, in the
Republic of France, Inventor.
I, WILLIAM PHILLIPS THOMPSON Fel. Inst. P.A. of the Agency for Foreign Patent
Solicitors 6, Lord Street, Liverpool, in the County of Lancaster, and 323 High
Holborn in the County of Middlesex, Civil Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention consists in a new means for the production of alcohol by the treat-
ment of Manioc root, (called in the Portugese colonies Mandioca.)
It is well known that the root of this plant-one of the euphorbiaciæ produces a
pure starch from which tapioca is made, but it has not been proposed till now to
apply the tubers of the said plant to the industrial manufacture of alcohol.
After gathering those roots of manioc which attain the size of beets, the inventor
submits them to a complete mechanical cleaning. They are then cut up into pieces of
convenient size. These are dried by preference in the sun, but if desirable they can
be dried by artificial heat.
The starch of the dry product is extracted by any appropriate means mechanical or
otherwise, and is transformed into glucose by the action of acids and preferably by
sulphuric and hydrochloric acid, or even by malt acting as a ferment.
The saccharification of the juice obtained by the preceeding treatment & the details
of which are the same as in the manufacture of alcohol from yams or potatoes for
example, is effected either in the open air or under pressure after which fermentation is
carried on according to well known processes and by ordinary means.

Republic of France, Inventor.
I, WILLIAM PHILLIPS THOMPSON, Fel. Inst. P.A. of the Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool, in the County of Lancaster, and 323 High
Holborn, in the County of Middlesex, Civil 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 :-
It is known that the manioc root produces starch, and that the sugar juices
extracted from it can be used for the production of alcohol.
It is known that the use of this root for the production of alcohol has also been
proposed by treating it through rasping, compression etcetera, but in no case has a
imethod been described which allows this raw material to be used in countries where
the manioc does not grow.
The fact is that this root cannot be used after having been transported at all,
because it would be decomposed, and would yield no alcohol; this is the reason why
in Europe this method of producing alcohol has not been used.
The present invention consists in a new method of industrial production of alcohol
by a special treatment of the manioc root (called mandioca in the Portuguese
Colonies).
For the industrial production of alcohol from this root, the inventor proceeds in the
following manner :
After the manioc roots, which attain the size of beetroots, have been dug up, they
are submitted to a thorough mechanical cleaning process; they are then cut up in
pieces of suitable size, and dried, preferably in the sun; this drying process may
however be performed by means of any kind of artificial heat.
By this process the root becomes transportable, and will keep until it is transformed
into starch.
From the roots dried in this way the starch is extracted by any suitable process
mechanical or otherwise, and is made into grape sugar by the action of acids prefer-
ably sulphuric and hydrochloric acid or even by malt acting as fermentor.
The saccharification of the juice obtained by the above method, the details of which
are the same as in the manufacturing of alcohol from potatoes or yams, is afterwards
effected either in the open air or under pressure, and then the fermentation is brought
about in the usual way.

page_text: By this process, a very advantageous raw material is obtained, for the manu-
facturing of alcohol, easily and economically transportable, as the water has been
eliminated by drying in the very place where the harvesting of the roots takes place.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my foreign
correspondent, I declare that what I claim is :-
The method of treatment of the manioc root, for the production of starch or alcohol
therefrom, consisting in cutting the root in pieces in its fresh state, and afterwards
submitting it to a complete drying process which allows its transportation and
conservation for ulterior utilization, by means of any suitable process.
