Extraction equipment for nitrogen-containing beverages

The invention relates to a beverage extraction device, in particular to an extraction device containing a nitrogen beverage, which can produce a nitrogen-containing beverage with dense bubbles, and has the advantages of convenient operation and good extraction quality.

The affluence of modern society makes the food content of modern people more rich and diverse. Among them, beverages are an indispensable element in modern diet. The variety of beverages can be basically divided into alcoholic beverages and non-alcoholic beverages. Let the beverages have different flavors or tastes to win the favor of consumers, and beverage suppliers or manufacturers will try their best to make new contributions.

Among the many non-alcoholic beverages, cold drinks have always been the most popular ones. Whether it is tea, flowers, coffee, etc., most of them are soaked under high pressure at high temperature, and then filtered by a filter. The extract is then added to ice cubes or refrigerated to get a cold drink or a cold drink. In the traditional extraction process, high temperature immersion will destroy the original materials (such as tea, flowers and ground coffee powder), causing excessive extraction and poor taste; in order to solve this problem, a cold extraction technology of beverage is introduced. .

A new type of cold drink called "Coffee Beer" is being loved and welcomed by consumers. "Coffee Beer" uses coffee as its main content because it is rich in bubbles and tastes delicious. It is named after beer.

In the published Chinese New Patent Grant No. CN204133216U, there is disclosed a "device for making coffee" capable of maintaining flavor at a relatively low temperature, the device comprising a barrel for storing cold coffee, nitrogen containing nitrogen. a tank, a discharge unit and a first cooling unit, wherein the nitrogen tank is connected to the barrel through the first line to be configured to supply nitrogen into the barrel to form a nitrogen-filled coffee, and the discharge unit is connected to the barrel through the second line to be configured to discharge the nitrogen-filled coffee And the first cooling unit encloses the second line to be configured to cool the nitrogen-filled coffee; the nitrogen gas is supplied to the barrel from the nitrogen tank through the first line. Therefore, nitrogen-filled coffee maintains a rich foam and flavor.

In the above-disclosed patented technology, nitrogen is blown into the coffee to facilitate dissolution into the coffee. Therefore, nitrogen-filled coffee can be formed in the tub. In order to effectively dissolve nitrogen into the coffee, it is possible to repeatedly supply nitrogen to the coffee. For example, nitrogen can be supplied to the coffee twice. However, this kind of blowing nitrogen into the coffee will overwhelm the coffee, which may cause excessive extraction and poor taste.
