Abstract

The present disclosure provides a beverage dispenser and a beverage brewing method. The beverage dispenser is formed with a liquid chamber, a brewing chamber, a heating chamber that can heat up liquid, and a pressure chamber that can pressurize the liquid. The liquid chamber, the heating chamber, the pressure chamber, and the brewing chamber form a circulating liquid circuit, in which the liquid formed in the liquid chamber enters into the heating chamber. The liquid is heated in the heating chamber and then enters into the pressure chamber. The liquid is pressurized in the pressure chamber and then enters into the brewing chamber, and then flows out of the brewing chamber and enters into the liquid chamber. The beverage dispenser and the beverage brewing method provided in the present disclosure overcomes the drawbacks of manually adding hot water and manually pressurizing for producing beverage.
