Methods and systems to deliver foamed beverages from liquid concentrate(s)
through a dispenser machine are presented. In an embodiment, the method
and system for improving foam quality by generating foam with the desired
texture, stability and bubble size distribution comprises use of a low
viscous liquid(s) to generate a primary foam, which is then stabilized by
mixing it with liquid(s) of higher viscosity. To create high quality
foam, different dosing protocols including two approaches such as
delivery of foaming liquid concentrates at different concentration, or
getting different concentration by varying water dosing times and/or flow
rates were used. Positive results were found for the dispensing systems
using milk and other liquid concentrates at specific dispensing
conditions (flow rates and times).
