Improvements in Treating or Ageing Spirit.
Year: 1892

page_text: This Print is in accordance with the Original Specification as it stands after Amend-
ment (under Section 18 of the Patents, &c. Act, 1883) as allowed by the decision
of the Comptroller General of the 15th day of February 1898.
I, RICHARD CLARKSON SCOTT, of 24, Drury Buildings, 21, Water Street,
Liverpool, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
According to this invention the spirit is exposed to the action of cold air that is
to say at about freezing point or below as distinguished from the comparatively
warm air hitherto employed.
By this means loss of strength, flavour, bouquet and aroma is avoided.
The air is used at ordinary pressure and is only brought once into contact with
the spirit.
In order that as large surfaces as possible of the spirit and air may be exposed
to each other the air may be blown through pipes dipping into the spirit or the
spirit is sprayed in a stream of the cold air.

Improvements in Treating or Ageing Spirit.
I, RICHARD CLARKSON SCOTT, of 24, Drury Buildings, 21, Water Street,
Liverpool, Manufacturer, 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 this invention the spirit is exposed to the action of a stream or
streams of cold air that is to say at about freezing point or below as distinguished
from the comparatively warm air hitherto employed.
By this means loss of strength, flavour, bouquet and aroma is avoided.
The air is used nearly at ordinary pressure and so that it is only brought once
into contact with the spirit and then passes away to the atmosphere or to be purified
and used again.
In order that as large surfaces as possible of the spirit and air may be exposed
to each other the spirit may be sprayed by means of the stream of cold air.

page_text: In all cases I prefer that the spirit should be articficially cooled to about
32° Fahrenheit or below before injecting it into the vessel.
In carrying out my invention the spirit may be introduced in the form of
minutely divided spray into the upper part of a vessel by means of cold air as
already stated up through which a slow current of air artificially cooled to about
32° Fahrenheit or below is maintained. The process may be carried on continuously
for any desired length of time in one vessel, the spirit to be sprayed into the upper
part of the vessel being taken from spirit contained in the lower part of the vessel.
The cold air may be admitted in numerous fine streams through fine perforations in
air supply pipes or passages above the level of the spirit at the lower part of the
vessel. The air after passing up through the vessel passes away and may be led
through a condenser where the impurities carried along with it will be condensed
or may be passed through a mixture of sulphuric acid and water.
In place of the spirit to be treated being passed several times in the form of
spray through the same vessel it may be passed successively in the form of spray
through a number of vessels up through each of which a slow stream of cold air is
maintained.
The vessels used-in conducting the process may very advantageously be old
sherry casks.
My object in treating spirit by bringing it when at a low temperature repeatedly
into contact with streams of cold air is to retain the best portion of the ethers in
the spirit whilst gradually eliminating from it the dangerous elements alike of the
spirit and fusel oil without impairing the character of its odour or taste or
appreciably its strength.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood that
I do not claim any process in which the spirit is not sprayed in a stream of constantly
changing and freely escaping air, but I declare that what I claim is :-
1. Treating or ageing spirit by bringing it into repeated contact with a stream
or streams of air reduced to about 32° Fahrenheit or below.
2. Treating or ageing spirit by introducing it as a minutely divided spray into
the upper part of a vessel through which a stream of cold air is continuously
maintained.
3. Treating or ageing spirit by cooling it to about 32° Fahrenheit or below and
then bringing it into intimate contact with air also cooled to about 32° Fahrenheit
or below.
