Treating Vegetable Non-conducting Substances to Prevent
Fermentation therein.
I, MAUNSEL CASWELL BANNISTER of Central Buildings, North John Street,
Liverpool in the County of Lancaster, Consulting Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates more particularly to the husks or ears of cereals as for
instance rice and oats, when used as insulating or heat, non-conducting material for
cold stores, refrigerators and the like, wherein food, generally is preserved, and
the object of this invention is the cleansing of the material and the removal of
foreign or organic particles or substances adhering thereto or contained therein
and which might ferment under favourable circumstances and be deleterious to the
food in close proximity to the material, and injurious to health, particles or dust
of the grain and of organic matter being unavoidably present after separation of
the grain.
The invention consists in subjecting the husks to a cleansing process by which
all foreign and organic particles and matter may be effectually removed.
The cleansing may be effected by forcing water or a solution of alum and water
or other solution through the husks when disposed on a perforated tray or in a
tank or suitable closed or partly closed vessel so that the particles of matter
adhering to the husks and mixed therewith shall be carried away with the liquid
as it passes through the perforations or from the tank.
Or the material may be agitated in a suitable vessel rotating or oscillating in
water or in a solution by which the solution or liquid takes up the foreign matter,
which is carried away thereby.
The husks may afterwards be dried in any suitable apparatus and a strong
current of air may be passed through them.
In some cases the cleansing may partly be effected by subjecting the husks
to the action of steam or hot air in a suitable closed or partly closed vessel.

I, MAUNSEL CASWELL BANNISTER of Central Buildings, North John Street,
Liverpool, in the County of Lancaster, Consulting 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 :-
This invention refers more particularly to the husks or ears of cereals such for
instance as rice and oats, when used as heat non-conducting or insulating material

page_text: in cavity walls of cold store chambers, refrigerators and for purposes where it is
desired to prevent conduction of heat and cold, other than those named; the
object of this invention being-the cleansing of the material and the removal of
foreign or organic particles or substances adhering to the husks or contained therein
which might ferment under favourable circumstances and be deleterious to food
when in close proximity to the material and injurious to health, particles or
dust of the grain and of organic matter being unavoidably present after separation
of the grain.
The invention consists in subjecting the husks to a cleansing process by which
foreign and organic particles and matter may be effectually removed.
In some cases the cleansing is effected by forcing water or a solution of alum in
water through the husks when deposited on a perforated tray or in a tank or other
suitable closed or partly closed vissel so that the particles or matter adhering to
the husks and mixed therewith shall be carried away with the liquid as it passes
through the perforations or from the tank.
In other cases the material may be agitatel in a suitable vessel which may
rotate or oscillate in water or in a solution of alum in water by which the solution
takes up the foreign matter and carries it away as it is discharged.
Sometimes wet steam of a suitable temperature is used to wash the husks, by
projecting the steam into a chamber containing the husks or by passing the husks
through a jet of steam issuing from a nozzle.
The husks are afterwards dried in any suitable way or by any suitable apparatus.
They may be so disposed that a strong current of air passed through them
evaporates all the moisture they contain.
In other cases I subject the husks to sufficient heat to destroy any germs contained
therein by confining them to the action of dry steam or hot air in a vessel or
container of any suitable form.
I wish it to be understood that I do not confine myself to any form or con-
struction of apparatus for carrying out the object of this invention which is the
cleansing of the husks or ears of rice and oats used as heat or cold non-conducting
or insulating material.
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 :-
First. Cleansing the husks of rice and oats to be used as heat and cold non-
conducting material substantially as described herein before.
Second. Subjecting the husks of rice and oats to be used as heat and cold non-
conducting material to the action of a solution of alum in water for the purpose
herein before described.
Third. Subjecting the husks of rice and oats to be used as heat and cold non-
conducting material to the action of heat sufficient to destroy organic matter which
might be contained therein, for the purpose hereinbefore set forth.
Fourth. Subjecting the husks of rice and oats to be used as heat and cold non-
conducting material to the action of steam of high temperature for the purpose
hereinbefore set forth.
Fifth. Subjecting the husks of rice and oats to be used as heat and cold non-
, conducting material to cleansing by washing or steaming and afterwards drying
by evaporating the moisture in an artificial manner, for the purpose hereinbefore
set forth.
