page_text: LILLIAN WARDLE, 6, Scalpeliffe Itoad, Burton-on-Trent, Staffordshire, do hereby
declare the nature of this invention to be as follows ;-
-
I take the spent or used hops after the same have been used by the brewers
and dry them preferably thoroughly baking to a crispness I mix with them w
suitable proportion of barm or yeast preferably the ordinary pressed barm from
the breweries in condition and period of fermentation most suitable for the pur-
pose of binding the hops together. The hops when so mixed and prepared I then
compress into cakes bricks or lumps. These I allow to stand in a dry place untill
by the process of evaporation and absorption the moisture from the yeast has in
part or wholly disapeared. The cake I then dry or bake by the assistance of heat--
or if baking is not desired I allow the cake to remain in a dry place or room,
or kilu untill sufficiently dry without the assistance of a high drying or baking
heat. In the process of mixing, sugar treacle, gluecose, spice condiment meal or
other suitable material or ingredients for the purpose of giving further body or
improving the flavour or quality can be added to the compost in suitable propor-
tions at will.
The purpose to be served by the making of a compost resulting from the admix-
ture of a suitable proportion of yeast with the crisply dried spent hops is the
manufacture of a more substantial and glutinous compost or cake than could
possibly be made by the hops alone. And the hops which are very light and
flimsy and of a bulky nature are broken up and reduced in bulk and also solidified
by admixture with the yeast-which is a much heavier substance-during the
process of preparation. The resulting-compost formed by the dried spent hops
charged with the yeast after the latter has been absorbed by the hops and again
dried off, is used as food for animals and also forms a valuable concentrated
manure.

İ, LILLIAN WARDLE (wife of William Wardle), of Number 6, Scalpeliffe Road,
Burton-on-Trent, 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:—
My invention relates to an improved process for preparing spent hops as an

page_text: :
article of food for cattle and for use as a fertiliser it is a well known fact that
spent or used hops are already dried and utilised as a cattle food and also that
spent hops are used as manure. The purpose to be served by my invention is
the manufacture of a composition or cake which whilst still being largely con-
posed of dried spent or used hops is made heavier and more substantial and of
greater value for feeding purposes or as a fertiliser by the addition of brewers
yeast or barm or such extracts or portion of the barm or yeast as may be most
suitable and convenient for the said purpose. I employ yeast or an extract of
yeast for so increasing the value of the hops in preference to any other material
or substance on account of the convenience in obtaining the same in large
quantities from the same source of supply as the hops and also on account of its
natural tendency to lend itself to absorption by an incorpation with the dry hops.
By mixing dry or semidry spent or used hops with a suitable proportion of yeast
or an extract of yeast an absorption of the yeast matter by the hope is effected
and a composition is formed that can be readily dried off."
Spent or used hops after being pressed by the brewers still contain a large
per centage of moisture and though I may for the purpose of carrying out my
process mix the hops in a semi-dry state as delivered from the press and without
further drying with the yeast I find the best results are to be obtained by first
thoroughly drying off the spent hops on a kiln or by atmospheric evaporation or
by the use of fans or other known process or machinery. Having so dried the hops
I then mix with or crush into the dry hops my yeast or extract of yeast, this is
readily absorbed by the dry fibrous hops and the resulting compost or mixture is
then dried off at a sufficiently high temperature to sterilise the yeast.
If I desire by my process to manufacture a loose composition or admixture for
feeding purposes I take equal quantities of dried spent hops and pressed yeast
preferably yeast fresh and crisp from the press and after rolling or crushing or
thoroughly mixing the yeast into the hops so as to ensure a complete absorption
of the yeast by the hops.
I dry the composition or mixture loosely and at a very high temperature as
quickly as possible after so mixing so as to effectually sterilise the yeast.
If I desire a brick or cake or lump for feeding purposes I vary the amount of
yeast using the same in sufficient quantity to bind the hops together and to
congeal the mixture under pressure into a cake and I allow the resulting lump
brick or cake to dry more gradually at a much lower temperature so as to avoid
running a fermentation in the centre of the cake afterwards more effectually
sterilising the cake by heat if required, the hops and yeast so dried with or with-
out the addition of other ingredients or seasoning or spices which may or may
not be added at will and when so mixed and dried forms a valuable food for
cattle.
•
If I desire by my process the manufacture of a fertilising composition I first.
wash the yeast in a liquor composed of a solution of fine lime and water. The
wash.giving the best results I find to be obtained by the use of fine slacked lime
which after being mixed with water I pass through a fine sieve or coarse filter
to remove any foreign substance or insoluble matter the proportion of lime I use
being equal to about 4 per cent, in weight of the yeast to be washed with sufficient
water to thoroughly disintegrate or separate and wash the particles or cells of the
yeast this mixture or wash now composed of a solution of lime water and yeast
is first thoroughly roused up and mixed and then pressed in an ordinary filter
press and the liquor ejected, the liquor extracts from and carries off a very large
proportion of the fertilising properties of the yeast I then mix the liquor so obtained
and which contains extracted matter from the yeast with dry or semidry hops and
dry off in the manner herein before described. The residue of solid matter left
in the cloth or filter press from which the fertilising fluid has been obtained or
extracted forms a valuable byc product which may be utilised in mixing with
the food compost manufactured by my process or the same may be used for various
other commercial or feeding purposes.

page_text: It wish it distinctly understood that the above proportions are given by way
of practical directions in carrying out my process and I do not limit myself to
the use of such proportions.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A process of drying hops loaded or charged with yeast or extract of yeast for
the purpose specified.
2. A process for the improvement in the weight quality and substance of dry
spent hops by mixing or charging the same with a suitable proportion of barm or
yeast or the extracted matter from the same and evaporating the moisture there-
from.
3. A process of preparing or extracting in part the fertilising qualities or pro-
perties of yeast for the purpose of utilising the same in the manner, herein
described.
i
4. As a product of manufacture dry spent hops wholly or partially impregnated
or coated with dry and sterilised barm or yeast or the extracted matter from tho
yeast.
5. The herein described process for preparing and drying hops charged with
yeast or extract of yeast.
