Abstract
Apparatus and method for determining the amount of carbon dioxide in continuously supplied liquids containing dissolved carbon dioxide, such as wine or other beverages. A constant-flow sidestream of the liquid is ejected in the presence of a carrier gas which dissolves carbon dioxide into a separating chamber under conditions which yield substantially instantaneous and substantially complete evolution of carbon dioxide from the liquid. The carrier gas and evolved carbon dioxide are conducted from the chamber to a carbon dioxide measuring and recording device, and the separated liquid that is depleted of carbon dioxide is drained from the chamber.
Claims13
A method of determining the amount of carbon dioxide present in a continuously supplied liquid containing dissolved carbon dioxide comprising the steps of:
- a. generating a constant flow sidestream of said continuously supplied liquid;
- b. generating a continuous flow of a gas which dissolves carbon dioxide;
- c. in the presence of said gas ejecting said sidestream into a confined volume under the influence of a pressure differential sufficient to cause substantially instantaneous and substantially complete evolution of carbon dioxide from said liquid leaving said liquid substantially depleted of carbon dioxide;
- d. conducting the evolved carbon dioxide and said gas to a carbon dioxide measuring station and at said station measuring the amount of carbon dioxide in the combination of said gas with said carbon dioxide;
- and
- e. draining said liquid depleted of carbon dioxide from said confined volume.
Apparatus for determining the amount of carbon dioxide present in a continuously supplied liquid containing dissolved carbon dioxide, comprising:
- a. means for generating a constant flow sidestream of said continuously supplied liquid;
- b. a continuous source of a gas which dissolves carbon dioxide;
- c. means defining a confined volume;
- d. means for ejecting said sidestream into said confined volume in the presence of said gas under the influence of a pressure differential sufficient to cause substantially instantaneous and substantially complete evolution of carbon dioxide from said liquid into said gas leaving said liquid substantially depleted of carbon dioxide;
- e. measuring means for measuring the amount of carbon dioxide in the combination of said gas with said carbon dioxide;
- f. a conduit between said confined volume and said measuring means;
- and
- g. drain means for draining said liquid depleted of said carbon dioxide from said confined volume.
