METHOD OF IMPROVING THE PRODUCTION OF FOAM DURING THE PREPARATION OF DRINKS FROM A CARTRIDGE AND DEVICE FOR ITS IMPLEMENTATION

摘要

The method involves injecting a phase comprising air that is compressed at a pressure lower than a pressure of opening of a cartridge or outflow of a beverage through the cartridge for forming an air storage pocket. A phase comprising water that is mixed with the air in the cartridge is injected to increase the inner pressure to that of the pressure of cartridge opening and beverage outflow to evacuate the beverage and to form foam. An independent claim is also included for a device for preparing a foam beverage from a cartridge.
