We ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER both of the Castle
Brewery, St Georges Road, Southwark in the County of Surrey, Consulting
Practical Brewers and Analytical Chemists, do hereby declare the nature of the
said Invention for IMPROVEMENTS IN THE TREATMENT OF GRAIN TO BE USED IN
BREWING, DISTILLING AND VINEGAR MAKING to be as follows:-
The invention relates to improvements upon an invention for which Letters
Patent were granted to us dated the 26th day of January 1881 N° 344 and has for
its object to facilitate the conversion of the grain in the mashing process.
When employing grain treated in the manner described in the specification of
the above recited Letters Patent we have found that during the brewing or mashing
process the grain which has been previously ground or crushed has subsided and
settled more or less on the bottom of the mash tun, especially when using rice and
maize, and this in consequence of obstructing the drainage of the wort has been
prejudicial or unfavourable to obtaining the greatest degree of extract from the
grain.
Now according to our present invention we obviate this defect by giving to the
said grain so treated, a very extended surface which has the effect of causing it to
float or to remain in suspension in the mash a sufficient time to allow of its proper
conversion thus enabling the diastase of the malt mixed therewith to attack and
act upon all its parts and thereby materially hastening its conversion and ensuring
the whole of the starch granules being acted upon.
In carrying our invention into effect we pass the grain after partial drying, but
still in a soft condition between rolls either cold or preferably heated by steam, gas
or other heating media in order to assist the drying process, and prevent the grain
sticking to the rolls, whilst in the event of any of the grain being hard such heated
rolls will act to soften the saine and thereby assist the action of the rolls upon the
grain.
This will have the effect of flattening the grain and it will leave the rolls in the
form of thin films, sheets, flakes or wafers which may be further dried if required
and then, after being broken up or not, according to circumstances, mixed with
gerininated barley malt and mashed and employed in the process of brewing,
distilling and vinegar making in the ordinary manner.

We ALEXANDER WILLIAM GILLMAN and SAMUEL SPENCER both of the Castle
Brewery, St George's Road, Southwark in the County of Surrey, Consulting
Practical Brewers, and Analytical Chemists do hereby declare the nature of the
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The invention relates to improvements upon an invention for which Letters
Patent were granted to us dated the 26th day of January 1881 N° 344 and has for
its object to facilitate the conversion of the grain in the mashing process.
When employing grain treated in the manner described in the specification of
the above recited letters Patent we have found that during the brewing or mashing
process the grain which has been previously ground or crushed has subsided and
settled more or less on the bottom of the mash tun especially when using rice and
maize and this in consequence of obstructing the drainage of the wort has been
prejudicial or unfavourable to obtaining the greatest degree of extract from the
grain.
Now according to our present invention we obviate this defect by giving to the
said grain so treated, a very extended surface which has the effect of causing it to
Hoat or to remain in suspension in the mash a sufficient time to allow of its proper
conversion thus enabling the diastase of the malt mixed therewith to attack and
act upon all its parts and thereby materially hastening its conversion and ensuring
the whole of the starch granules being acted upon.
In carrying our invention into effect we pass the grain, after partial drying, but
still in a soft condition between rolls either cold or if required heated by stean, gas
or other heating media in order to assist the drying process and prevent the grain
sticking to the rolls whilst in the event of any of the grain being hard, such heated
rolls will act to soften the same and thereby assist the action of the rolls upon the
grain.
This will have the effect of flattening the grain and it will leave the rolls in the
form of thin films, sheets flakes or wafers which are further kiln dried and then,
after being broken up or not according to circumstances mixed with germinated
barley malt and mashed and employed in the process of brewing distilling and
vinegar making in the ordinary manner.
If the flakes are too large they are broken up in order to occupy less space in
packing.
Or instead of employing rolls heated by special apparatus and driven at an equal
speed we may employ rolls which are driven at a differential speed, five revolutions
of one roll to six of the other have been found to answer well, this will have the
effect of producing the required degree of heat and will at the same time otherwise
facilitate the process.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is
Treating grain for brewing, distilling and vinegar making by first submitting it
to the process described in the specification of our aforesaid Patent, then by
partially drying the same and flattening it by passing it through rolls or otherwise
and then further drying it if required substantially as herein described and for the
purpose stated.
