摘要

The process of cooling a neck of a bottle (3), which is used in the preparation of wines by Champagne method, comprises placing the bottles in a bottom head, placing the necks of the bottles in a closed space, and passing an air stream through the closed space, which is previously cooled. The bottles are shifted in a reverse direction of the cooled air stream. The air stream is cooled through liquid nitrogen or other cryogenic liquid that is injected directly into the air stream, or indirectly through a refrigeration heat exchanger placed on the path of the stream. An independent claim is included for a machine for cooling a neck of a bottle, which is used in the preparation of wines by Champagne method.
