AN IMPROVED PROCESS IN THE MANUfacture of SELF RAISING FLOUR
Year: 1884

page_text: I GEORGE THOMAS CARTER of 25 The Grove Reading Berks Corn Merchants
Clerk do hereby declare the nature of my invention for AN IMPROVED PROCESS
IN THE MANUfacture of SELF RAISING FLOUR to be as follows:-
Take of good wheaten flour of ordinary strength and colour (that which has
been milled on the Hungarian system being preferable) 246 lbs. and having spread
it on iron plates to the depth of one inch pass it through one of Messrs Baker Sons
travelling ovens (which had previously been heated to about 200 degrees farenheit)
the result being the withdrawal of the moisture from the flour.
Having permitted it to cool pass it through a flour mixer adding at the same
time 30 lbs of finest Patna rice flour, the dry nature of which will entirely absorb
any moisture that is left.
At the expiration of forty eight hours this should again be passed through the
inixing machine, with the following ingredients added thereto, 2 lbs of Bi carbonate
of Soda, 2 lbs pulverized White Sugar 1/4 lbs. Tartaric Acid (Seagers make) 4 oz
Bitartrate Potash 3 oz Carbonate of Lime, the result will be a Self Raising Flour,
which when cooked will be perfectly white, and have a pleasant biscuit like flavour,
at the same time proving very beneficial to persons of delicate digestion.

page_text: I GEORGE THOMAS CARTER 25 The Grove Reading Berks "Manager to a Corn
Merchant" do hereby declare the nature of my invention for AN IMPROVED
PROCESS FOR THE MANUFACTURE OF SELF RAISING FLOUR and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
In carrying my present Invention into practice I take good wheaten flour of
ordinary strength and colour (that which has been milled on the Hungarian
system being preferable) and spread it on iron-plates to the depth of about one
inch and pass it through one of Messrs Baker and Sons travelling ovens or other
suitable heating apparatus heated to about 200 degrees fahrenheit for the purpose
of partially cooking drying or withdrawing the ordinary moisture from the flour.
then permit such flour to cool, and pass it through a flour mixer adding at the
_same_time_to_every 240 lbs of such-wheaten-flour-about 30 lbs. of Finest Patna
Rice Flour, which will entirely absorb any moisture-that-is-or-may-be left..
At about 48 hours afterwards this admixture is again passed through the
mixing machine, with the following ingredients in about the following pro-
portional quantities added thereto, of Bi-carbonate of Soda and Pulverized White
sugar cach about 2-lbs; of Tartaric Acid (preferably Senger's make) about 12 lbs;
of Bitartrate of Potash about 4 ounces, and of Carb. Lime about-3-ounces.
The resultant-admixture-will-be-a Self Raising Flour which when cooked will be
perfectly white and have a pleasant biscuit like flavour and will not requiro
anything further to-be-added-when-used-to-give the desirable lightness to the
pastry or articles made therefrom; and such Hour and pastry will prove easily
digestible and very beneficial to persons of weak digestion owing to the contained
Carb. Lime; and owing to tho partial cooking and extraction of all moisture the
improved flour will keep in good condition for a very considerable length of time
and will not be liable to deterioration, or to premature action or to loso its
qualities in any climate.
'
Having now particularly described and ascertained the nature of my said
invention and in what manner the saine is to be performed I declare that what
I claim is:
The herein before described improvements in the process of manufacturing self-
raising flour; and which improvements consist in the partial cooking or drying of
the wheaten flour from which the improved four is to be made, and in the
subsequent addition to such partially cooked or dried flour in the manner described
of the finest patha rice flour and the other said materials or ingredients in about
tho respective proportional quantities mentioned; substantially as and for the
purposes described.
