Foam analyzing method and apparatus.

摘要

A method of analyzing the visually perceptible characteristics of foamable liquid, such as beer, comprises pouring a known quantity of the foamable liquid from a storage container (28) into a clear beaker (10). A camera (12) produces a video image of the beaker (10) and its liquid and foam contents. A series of such images are periodically acquired over a definite time period. The images are electronically analyzed to derive numerical values indicating the different characteristics. A system for performing the method also is described.
