PROVISIONAL SPECIFICATION.
An Improved Method of Facilitating the Drying of Distillers' Spent
Wash and similar Matter.
I, EDUARD LARSEN, of 41 Eastcheap, in the City of London, Gentleman, do
hereby declare the nature of this invention to be as follows:-
Distillers' spent wash and similar sticky and glutinous matters are extremely
difficult to dry owing to their greasy condition.
The material is first reduced to as dry a state as possible by being allowed to settle
in a tank or the like, liquor being run away afterwards, and I also further remove as
much moisture as I can by means of presses and similar arrangements.
Having by such well known means eliminated a great deal of the fluid, an article is
arrived at which still contains some 50% of moisture, to facilitate the drying of
which, I mix it with a suitable proportion of husks from oats, rice cones, malt coombs,
brewers' grains, or similar light, bulky and spongy matter, preferably in a dry state.
Such husks or coombs will if dry absorb a great part of the moisture contained in the
spent wash, but the object chiefly aimed at is to alter the consistency of the material,
so that it becomes looser and less sticky, and less apt to clog, so that it does not
adhere to the machinery and appliances used in drying it, and it also throws off far
more readily its moisture.
After the material has finally been dried by means of any ordinary machines
commonly used for drying grains and similar materials, I can remove the husks and
coombs added by simply sifting the material and use them over and over again for a
fresh quantity of spent wash.
COMPLETE SPECIFICATION.
An Improved Method of Facilitating the Drying of Distillers' Spent
Wash and similar Matter.
I EDUARD LARSEN of 41 Eastcheap in the City of London, Gentleman 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:
Distillers "Spent Wash" and similar sticky and glutinous matters are extremely
difficult to dry owing to their greasy condition.
The material is first reduced to as dry a state as possible by being allowed to settle
in a tank or the like, liquor being run away afterwards, and I also further remove as
much moisture as I can by means of presses and similar arrangements.
Having by such well known means eliminated a great deal of the fluid, an article
is arrived at which still contains some 50% of moisture, to facilitate the drying of
which, I mix it with a suitable proportion of husks from oats, rice cones, malt coombs,
brewers grains or similar light, bulky and spongy inatter, preferably in a dry state.
Such husks or coombs will if dry absorb a great part of the moisture contained in the
"Spent Wash," but the object chiefly aimed at is to alter the consistency of the
material, so that it becomes looser and less sticky, and less apt to clog, so that it does
not adhere to the machinery and appliances used in drying it, and it also throws off
far more readily the moisture.
After the material has finally been dried by means of any ordinary machines
го

coombs added by simply sifting the material and use them over & over again for a
fresh quantity of "Spent Wash."
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The method of drying Distillers "Spent Wash" or similar greasy, fat substances
by mixing it with a suitable quantity of husks from oats, rice-cones, malt roots,
brewers or distillers grains, or similar bulky and spongy matter, so as to produce a
larger drying surface and prevent the material from adhering to any machinery after-
wards used for the drying, as herein described.
2. Removing the husks, cones & etc. by sifting as herein described.
EDUARD LARSEN.
