COMPLETE SPECIFICATION.
Improved Food Products and Apparatus for Preparing the same.
I, JAMES CAMPBELL of 816 Lombard Street in the City and County of San
Francisco, State of California, U.S.A. Merchant, 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 a certain improvement in food products, and it consists in
a mixture and peculiar treatment of grains whereby I impart to them certain
qualities not contained by either of the grains separately, or previous to my
treatment.
It also consists in an apparatus for preparing the grain.
The figure shewn upon the accompanying sheet of drawings is a general view of
the apparatus.
In carrying out my invention I take wheat barley and rye in equal proportions.
The whole barley is first elevated by an elevator A about sixty or seventy feet,
and is delivered from the top of the elevator upon an inclined directing chute B,
which delivers it so as to fall through the air freely and into a receiving bin or
hopper.
After this operation the grain is run through a purifier C of any suitable form,
and is again elevated and discharged through the air, and falls into a receiving bin
or hopper D. From this hopper it is led through a chute E into the receiver or
hopper F from which it is raised by the elevator A to be again discharged.
From another receptacle the wheat is led by a similar chute into the hopper F,
and from this the barley and wheat thus mixed is elevated and discharged through
the air, and the same process gone through, including the cleaning.
These mixed grains are then delivered into the hopper F and the rye is then added,
and the whole body of the grain is again elevated and discharged through the
atmosphere in the same manner as at first described.
After these various operations have been completed the mixed grain is ground to
a sufficient degree of fineness, and is then in condition to be made up into bread or
other products for consumption.
The action of the air upon the grain appears to add a considerable amount of
phosphoric acid to that already contained in the grain, at least the result of many
careful analyses of the separate grains before and after this process has shown this
to be a fact, and the repeated passages through the air and the cleaner or purifier,
thoroughly mixes and cleans the grain.
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 :-
:―
1st. A process of preparing grain as a food product, consisting in elevating equal
parts of wheat, barley and rye, and dropping them through the air into receiving
bins, passing the grains through a purifier and again elevating and discharging
them through the air, and mixing the different grains together and repeating the
process one or more times substantially as herein described.
2nd. An apparatus for preparing grain before grinding, consisting of an elevator
by which the grain is raised and discharged from a height, a receiving bin into
which the grain falls at the bottom, a chute through which it is carried, and a

page_text: hopper at the foot of the elevator into which the grains are successively delivered,
and from which they are raised by the elevator, substantially as herein described.
