PROVISIONAL SPECIFICATION.
The Manufacture of a Malt Product called Wheat Coffee.
I CARL HEINEMANN of No. 8 Wilhelmstrasse Hamburg Germany Merchant do
hereby declare the nature of this invention to be as follows:-
According to this invention I produce a kind of roasted wheat malt material
which is to be used as a substitute for coffee by subjecting decorticated wheat to a
sprouting process, cleaning off the germs, and then roasting it.
A suitable mode of carrying out this invention is as follows:-Well assorted strong
wheat ("Blumenweizen ") is first decorticated and then passed through a sorting machine
("trieur") for removing dust and other extraneous matter. The wheat is then put
into stone vats and after being kept therein for two or three days exposed to a
constant flow of fresh water, it is passed through suitable sieving apparatus and
left to sprout on oaken floors, but in order to produce even germination it is turned
over about every three hours, day and night, by suitable machinery. The sprouting
wheat is then put into a machine for cleaning off the germs and conveyed to drying
kilns under increasing temperatures while being frequently turned over. The material
having been polished in a machine for effecting uniformity of the grains is then
roasted in suitable drums. The whole manufacture is by preference effected by steam-
worked machinery and the water used must be the purest mountain spring
water.

COMPLETE SPECIFICATION.
The Manufacture of a Malt Product called Wheat Coffee.
I, CARL HEINEMANN, of No. 8, Wilhelmstrasse, Hamburg, Germany, 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:-
According to my invention I produce a kind of roasted wheat malt material
which is to be used as a substitute for coffee or to be used in combination therewith.
For this purpose I subject decorticated wheat to a sprouting process, clean off the
germs and then roast it."
A suitable mode of carrying out this invention is as follows:-Well assorted strong
wheat such for instance as the strong large grained Silesian wheat called "Blumen-
weizen" is first decorticated and then passed through a sorting machine ("Trieur ")
for removing dust and other extraneous matter. The wheat is then put into stone
vats and after being kept therein for two or three days exposed to a constant flow
of fresh water it is passed through suitable sioving apparatus and left to sprout on
oaker floors. In the example named this takes about six days. But in order to
produce even germination it is turned over about every three hours day and night by
suitable machinery or appliances. The sprouting wheat is then put into a machine
for cleaning off the germs and conveyed to drying kilns under increasing temperatures
while being frequently turned over. As an example the material is first kept for
about 24 hours in a kiln at about 110° F, then for about the same time in a kiln at
about 133° F, and then in a kiln at about 178° F, the material being turned over by
hand every hour. The material having next been polished in a machine for effecting

page_text: uniformity of the grains is then roasted in suitable drums. The whole process is by
preference effected by steam worked machinery and the water used should be the
purest mountain spring water.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture of a malt product called wheat coffee being a substitute
for coffee substantially in the manner described.
2. As a new product, wheat coffee being a malt product made from wheat.
