Abstract
A beer foam reducing apparatus disposed for placement into the beer delivery lines between a keg and a beer serving spout to prevent pressurized carbon dioxide from entering the delivery line between the apparatus and the serving spout when a keg empties of beer. The apparatus comprises a base with a shallow receptacle disposed to receive an inverted, clear plastic container for sealed, threaded engagement. The plastic container is easily removed for cleaning or replacement and easily sealed for operation. The apparatus also comprises an inlet and outlet in the base, a float disposed for releasably sealing the outlet of the base when a keg empties, and a flow control column secured in the base and extending upwards into the inverted container. Single handed manipulation of a handle leveraged against a mounting bracket regulates operation of the flow control column, and specifically the venting of pressurized carbon dioxide and releasing of the float to begin delivery of beer through the outlet.
