I ARTHUR CHARLES HENDERSON of 47 Museum Street Oxford Street in the
Parish of Bloomsbury and county of Middlesex Civil Engineer and Patent Agent
do hereby declare the nature of the said invention for AN IMPROVED PROCESS OF
MANUFACTURING SUGAR FROM AMYLACEOUS AND CELLULOSE MATTERS a commu-
nication to me from abroad by Gabriel Durozad of the city of Lyons in the
Republic of France.
This invention has for its object the manufacture of sugar from amylaceous,
cellulose, fecula, starch, roots, tubercles, or plants containing such matters.
No acid is used in the process, so that crystallization can be effected without
trouble or disorder.
°
By preference as being most economical I extract the fecula of potatoes
25% of which I mix with 75% of water, this mixture is placed in a boiler or
digester and is then boiled to a pressure of 4 atmospheres, care being taken not to
exceed the temperature of 125 degrees. This mixture is removed from the
digester either by suction appliances or by a pump and is conducted by coolers of
some sort to bacs or vats where it is allowed to cool down to 45 degrees centigrade,
10% of brown kiln dried malt is then added and stirred, it is then allowed to
rest about 2 hours.
The sirupy liquid is then removed from the vats, and is placed in a vacuum
evaporator, the tubes being heated, the temperature for evaporation should not
exceed 70 degrees centigrade.
When the sirup comes to jelly it is withdrawn and crystallized in moulds and
dried in the usual manner.

I ARTHUR CHARLES HENDERSON of 46 Southampton Buildings Holborn in the
county of Middlesex Patent Agent do hereby declare the nature of the said inven-
tion for AN IMPROVED PROCESS OF MANUFACTURING SUGAR FROM AMYLACEOUS AND
CELLULOSE MATTERS a communication to me from abroad by Gabriel Durozad
of the city of Lyon in the Republic of France and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement, to be as follows:-
This invention has for its object the manufacture of sugar from amylaceous,
cellulose, fecula, starch, roots, tubercles, or plants containing such matters.
No acid is used in the process, so that crystallization can be effected without
trouble or disorder. By preference (as being most economical) I extract the fecula
of potato, 25 per cent of which I mix with 75 per cent of water: this mixture is
placed in a boiler or digester, and it is then boiled to a pressure of 4 atmospheres,
care being taken not to exceed the temperature of 125 degrees.
This mixture is removed from the digester either by suction appliances, or by a
pump, and is conducted by coolers of some sort to bacs or vats, where it is allowed
to cool down to 45 degrees centigrade, 10 per cent of brown kiln dried malt is then
added and stirred, it is then allowed to rest about two hours.
The sirupy liquid is then removed from the vats, and is placed in a vacuum
evaporator, the tubes being heated, the temperature for evaporation should not
exceed 70 degrees centigrade.
When the sirup comes to jelly or to pearl it is withdrawn and crystallized in
moulds, and dried in the usual manner.
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 method of manufacturing sugar from amylaceous and cellulose
matters consisting
1st In heating the amylaceous and cellulose matters in proportions of about
25 per cent of the matters to 75 per cent of water, in a digester at a pressure of
4 atmospheres, and not exceeding a temperature of 125 degrees.
2nd In cooling the mixture to 45 degrees.
3rd In the addition to the sirupy liquid of about 10 per cent of brown kiln dried
malt, and allowing it to stand two hours.
4th In evaporating the sirup in a vacuum evaporator maintaining a temperature
of 70 degrees.
