page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :—
The said invention relates to an article of food for both human and animal
consumption, and the utilization of substances heretofore considered worthless, for
food or other purposes, and succinctly is as follows.
In the rendering of lard, tallow or other fats, a considerable quantity of water is
necessarily present, or introduced in the rendering tanks, which water is known
in the industry as "Tank-Water." This tank-water, although apparently limpid,
contains about ten per cent of solid matter. Such tank-water has heretofore been
simply an offensive element in the rendering of fats, and has been almost univer-
sally discharged into the sewers, or disposed of with the other offensive surrounding;
of the rendering establishment, and such water is the principal source of the
offensive and deleterious odours, which arise in the rendering of fats. Attempts
have been made to utilize this tank-water as a fertilizer, but by reason of its
peculiar character, the object to be obtained, has met with indifferent success.
The ten per cent of solid matter contained in solution in this tank water is
organized substantially as follows; Mineral salts and an albuminous substance, of
which there is gelatine or glue, syntonine and perhaps other products; of this ten
per cent of solid matter about fifteen per cent of the same is nitrogen.
My food product and method or process of preparing the same are substantially
as follows:
1. The tank water is drawn into separate vessels or apartments, and there
evaporated until the above indicated solid matter remains and has about the
consistency of syrup. Even in this condition, it is a palatable and nutritious
article of semi-liquid or solid food.
2. This syrup is then thoroughly intermingled by hands or mechanical means
with corn-meal flour, seeds, husks of seeds, grain, or other farinaceous substance,
and the new composition so intermingled then subjected to heat, or evaporation,
ID 171

page_text: until it reaches the desired condition as an article of food; this intermingling
may be done at any degree of beat, and either by means of steam pressure or
otherwise.
3. This food mixture product is then subjected to a grinding or pulverizing
process, by means of the ordinary grinding mill, or otherwise, as its final best form
for a food product. Among the various farinaceous substances which may be used
to advantage in my process, because of their cheapness and general convenience,
I mention, without, however, limiting myself to them alone, meal, brewers grains,
the waste of glucose works and of distilleries. This admixture of syrup and
farinaceous substances may be in any desired proportion, but I have found that
twenty five to thirty per cent of syrup produces the best result and product. The
proportions of the ingredients, however, may be varied as desired, and also the
form of the product, that is, it may be ground, or it may be pressed into the form
of cakes..
The great superiority of such a food, as herein described over that of corn alone,
consists in the increased amount of protein-compounds or flesh forming albuminoids
that this tank water holds in solution, namely, fifteen per cent of nitrogen, not as
ammonia, but as álbuminoid. When thus properly mixed and reduced to dryness,
it furnishes a most desirable food, in every way healthful and pleasant.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be perforined as communicated to
me by my foreign correspondent I declare that what I claim is,
First. The improved food product herein described, produced by the evaporation
of tank water, containing the substances herein described, to the condition of
syrup, and the intermingling of the same with farinaceous substances, and the
evaporation of such admixture, substantially as described.
Second. The production of the syrupy matter by the evaporation of tank water,
the admixture of the same with farinaceous substances, the evaporation of such
admixture to the desired condition of dryness, and the grinding of pulverization
of such product substantially as set forth.
Third. The process herein described, of treating the solid matter contained in
tank water, in the production of a food product, substantially as set forth.
Fourth. The improved food product described herein, in dry or granular form,
consisting of tank waste incorporated with a farinaceous substance..
