Abstract: The invention relates to a device for generating and storing carbon dioxid snow, comprising a container into which an expansion nozzle connected to a supply line for liquid carbon dioxide and a gas extraction line open, a removal device for removing carbon dioxide snow out of the container, and a measuring device for detecting the fill level of the carbon dioxide snow in the container. According to the invention, the measuring device comprises a photoelectric sensor unit which is arranged at a vertical distance to the base of the container and which comprises a light-emitting transmitter and a light-sensitive receiver.

Abstract: In order to meter carbon dioxide snow, a storage container has an output unit, which comprises: an output opening, which is arranged laterally in the bottom region of the storage container; and a horizontally movable sliding element, which cooperates with the output opening. In order to fill the storage container with carbon dioxide snow, at least two snow horns are provided on the storage container, in which snow horns liquid carbon dioxide is converted into a mixture of carbon dioxide snow and carbon dioxide gas. The mouth openings of the snow horns point toward each other at least in one direction component so that the material flows exiting therefrom are directed at least partially toward each other. This facilitates the separation of snow and gas and increase the efficiency of the device.

Abstract: For charging a refrigerant-receiving compartment of a cooling container with dry ice, a reservoir vessel has a dispensing opening and a dispensing unit which cooperates therewith and by means of which dry ice blocks stored in stacks in a magazine of the reservoir vessel are ejected one after the other from the reservoir vessel and are respectively inserted into a refrigerant-receiving compartment of a respectively provided cooling container. This makes it possible to provide cooling containers in rapid succession with a precisely metered quantity of dry ice as refrigerant.
