Title: DEVICE FOR METERING CARBON DIOXIDE SNOW
Abstract:
The invention relates to a device for metering carbon dioxide snow comprising a storage container and a discharge opening arranged in the base of the storage container. A horizontally moveable sliding base is arranged in the region of the discharge opening, by means of which the discharge opening can be opened and closed. a horizontally moveable separation base is positioned vertically at a distance from the sliding base, which can be moved inside the storage container. After filling the storage container with carbon dioxide snow, a metered amount of carbon dioxide snow between the separation base and the sliding base is separated by means of the separation base, which amount is discharged via movement of the sliding base into the open position thereof. The invention permits the discharge of a precisely metered amount of carbon dioxide snow.
