Open extract beverage dispenser and method for using the same

An open extract beverage dispenser, comprising:

• a storage device connected to an airpump, used to produce and store liquid with nanobubbles;
• a connection and circulation device, of which one end is connected to the storage device;
• an extraction device, which is connected to another end of the connection and circulation device, the extraction device comprises an extraction part where a solid to be extracted is placed and a liquid storage part that accommodates the extraction part, the liquid with nanobubbles flows into the liquid storage part from the extraction part after an extraction of the solid to be extracted;
• and
• the connection and circulation device comprises a first conveyor and a second conveyor, wherein the first conveyor connects the extraction part and the liquid storage device and channels the liquid with nanobubbles into the extraction part for mixing with the solid to be extracted, the second conveyor connects the liquid storage part and the extraction part and re-channels solution in the liquid storage part into the extraction part for re-mixing with the solid to be extracted;
• wherein the extraction device further comprises an energy generation device, which is installed below the extraction part and is used to emit energy to accelerate the bursting of nanobubbles of solution in the extraction part and the liquid storage part.
