PROVISIONAL SPECIFICATION.
A Process for Recovering Beer, Ale, and Porter from Vat Bottoms,
Vat Sweepings, or Vat Deposits generally.
I, ALEXANDER FORBES WATSON, of No. 41, Grosvenor Square, Rathmines, in
the County of Dublin, Chemist, do hereby declare the nature of this invention
to be as follows:-
"
"
The word "beer" shall hereinafter mean beer ale and porter or either of them
and the word sweepings shall mean vat bottoms vat sweepings and vat
deposits or either of them.
It is usual for the beer contained in sweepings to be wasted or imperfectly
recovered by filtration.
My invention relates to a process which consists in heating the sweepings
up to a temperature or temperatures from 105 degrees Fahrenheit to 212 degrees
Fahrenheit and in maintaining them at those temperatures for a suitable time
(ten minutes or less) and thereafter cooling them quickly by refrigeration―
the whole process to be conducted in a closed vessel or vessels suitably disposed.
The treated liquids are allowed to remain at rest either in the vessel in which
they are treated or in tanks or vats until the deposit has settled when the super-
natant beer can be withdrawn clear.
Dated this 22nd day of February 1898.
A Process for Recovering Beer, Ale, and Porter from Vat Bottoms,
Vat Sweepings, or Vat Deposits generally.
I, ALEXANDER FORBES WATSON, late of No. 41, Grosvenor Square, Rathmines,
in the County of Dublin, but now of 38, Westmoreland Street, in the City of
Dublin, Chemist, 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;-
-
The word beer shall hereinafter mean beer, ale and porter or either of them
(where the context so admits) and the word bottoms shall hereinafter mean vat
bottoms, vat sweepings and vat deposits or either of them (where the context so
admits).
It is usual for the beer contained in the bottoms to be wasted or imperfectly
recovered by filtration or settling.

page_text: My invention relates to a process which consists in heating the bottoms up
to a temperature or temperatures between 105 degrees Fahrenheit and 212 degrees
Fahrenheit best to temperatures between 130 and 140 degrees Fahrenheit and
in maintaining them at those temperatures for a suitable time (five to ten
minutes) and thereafter cooling them quickly by refrigeration, the whole pro-
cess to be conducted in a closed vessel or vessels. The treated liquids are
allowed to remain at rest either in the vessel in which they are treated or in
tanks or vats until the deposit has settled when the supernatant beer can be
withdrawn clear.
My invention supplies a method for the recovery of beer from waste liquids
known as vat bottoms vat sweepings or vat deposits and it effects this by con-
verting the flocculent precipitate which is mixed with the beer in the thick
deposits of vats into a compact precipitate which settles easily leaving the beer
clear and easily separable from the precipitate.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The herein described process for recovering beer ale or porter from vat bottoms
vat sweepings or vat deposits by heating them up in a closed vessel to a
temperature or to temperatures between 105 degrees Fahrenheit and 212 degrees
Fahrenheit and by maintaining them at those temperatures for from five to ten
minutes and by thereafter cooling them quickly by refrigeration in the same
or in another closed vessel and by allowing the deposit to settle and withdrawing
the clear supernatant beer.
