Abstract: This invention relates to a novel method and system for dispensing CO2 vapor without over pressurization from a system having multiple containers. The system includes one or more liquid containers and one or more vapor containers. The system is designed to operate in a specific manner whereby a restricted amount of CO2 liquid is permitted into the vapor container through a restrictive pathway that is created and maintained by a shuttle valve during the filling operation so that equalization of container pressures is achieved, thereby allowing shuttle valve to reseat when filling has stopped. During use, a pressure differential device is designed to specifically isolate the vapor container from the liquid container so as to preferentially deplete liquid CO2 from the vapor container and avoid over pressurization of the system until the vapor container becomes liquid dry. The system can be operated so that at least 50% of the CO2 vapor product is dispensed from the vapor container.

Abstract: A nitrous oxide charging system to make whipped cream by charging food-grade N2O gas into a whipped cream dispenser that contains a certain amount of heavy cream is provided. The charging system includes a compressed gas container with liquefied nitrous oxide and a delivery unit that comprises an on/off valve; a pressure regulator configured to operate at a controlled outlet pressure; and a flexible tubing connecting with a dispenser. The charging system also includes a means to select the optimum delivery pressure based on the amount of heavy cream, and the accepted tolerance of the delivery pressure. An optional dispenser kit is also provide that can include a dip tube and/or oscillating arm-like structures as part of a dispenser kit operably connected to the dispenser to promote mixing and chemical solvation.
