Abstract: In a process for cooling and atomizing liquid or pasty substances or mixtures of substances, a liquid or pasty substance/mixture of substances is combined with liquid or supercritical carbon dioxide and then the mixture of liquid or pasty substance/mixture of substances and liquid or supercritical carbon dioxide is expanded. An apparatus for cooling liquid or pasty substances or mixtures of substances has a storage vessel for the liquid or pasty substance/mixture of substances, to which is allocated a line in which a device for transporting the liquid or pasty substance/mixture of substances is disposed. The apparatus has a source of liquid or supercritical carbon dioxide, to which source is allocated a line, and it has a connection point via which the line allocated to the storage vessel for the liquid or pasty substance/mixture of substances is connected to the line allocated to the source of liquid or supercritical carbon dioxide, and which has an expansion apparatus.

Abstract: The invention concerns a process and device for metering small amounts of a low boiling liquified gas which flows from an orifice of a cold-insulated vessel. In this process and device the orifice of the vessel is sealed off by a gas bubble.

Abstract: Food is packaged under a protective gas in synthetic containers having flexible lids. The sequence of the packaging steps is product filling, lid application, flushing with a protective gas, and sealing the lid. The flushing takes place wherein the lid is affixed to the container edge at at least one location, while one side of the lid is slightly lifted so that the protective gas can be blown therein.
