Method of freezing and preserving drink

Abstract

A method of freezing and preserving a drink comprising steps of obtaining the drink, putting the drink in a container, and pouring liquid nitrogen into the container from an opening of the container, so that the liquid nitrogen spreading to a surface of the drink, wherein the surface of the drink is frozen and becomes a frozen layer due to low boiling point of the liquid nitrogen, and the drink under the frozen layer remains liquid which can be preserved in a low temperature under the frozen layer.

What is claimed is: 
     
         1 . A method of freezing and preserving a drink comprising steps of:
 obtaining the drink;   putting the drink in a container; and   pouring liquid nitrogen into the container from an opening of the container, so that the liquid nitrogen spreading to a surface of the drink,   wherein the surface of the drink is frozen and becomes a frozen layer due to low boiling point of the liquid nitrogen, and the drink under the frozen layer remains liquid which can be preserved in a low temperature under the frozen layer.   
     
     
         2 . The method of freezing and preserving a drink of  claim 1 , wherein the drink is a mixture of different drinks. 
     
     
         3 . The method of freezing and preserving a drink of  claim 2 , wherein the drink is a cocktail made with a predetermined percentage of said different drinks. 
     
     
         4 . The method of freezing and preserving a drink of  claim 1 , wherein the drink is not a mixture of different drinks. 
     
     
         5 . The method of freezing and preserving a drink of  claim 1 , wherein the liquid nitrogen is stored under high pressure.
