An apparatus and a method provided for spraying a coolant to a work piece include a coolant feed line, at least one delivery nozzle for delivering the coolant, and shielding means which surround at least part of said delivery nozzle. The shielding means are arranged with the work piece to form an essentially closed space, and said shielding means includes exhausting means for exhausting gas from the essentially closed space, and means for keeping the outside of the shielding means at a temperature above the dew point.

An apparatus for depositing solid carbon dioxide on items to be refrigerated comprises a device (10) operable to convert a stream of liquid carbon dioxide into a forward flow of gaseous carbon dioxide containing entrained particles of solid carbon dioxide, a carriage (8) upon which said device (10) is mounted for translating in opposite directions and means for moving said device so as to direct said stream towards a plurality of individual items to be refrigerated.

Refrigeration apparatus

A method of forming glass containers, including the steps of drying a stream of air, passing the dried air into a vacuum-insulated mixing chamber, evaporating liquid cryogen in the mixing chamber, allowing the resulting cryogen vapor to mix with the air to form a mixture at a temperature below -20.degree. C., passing the gas mixture into a vacuum-insulated manifold, and causing the gas mixture to flow from the manifold and into the insides of glass containers being formed in molds to cool the containers.
