An air compressed coffee or tea making machine includes an air tank storing high pressure air; the air tank being connected to an air compressor for compressing external air so as to drive the high pressure air within the air tank; at least one liquid storage tank for storing liquid therein; a filtering tank installed below the air tank and connected to the liquid storage tank; a receiving tank installed below the filtering tank; the receiving tank serving for receiving coffee powders or tea powders therein. The liquid of the liquid storage tank is filled into the filtering tank; by the high pressure air from the air tank, liquid within the filtering tank suffers from a uniform air pressure and then flows to the receiving tank; as a result, the liquid is uniformly mixed with the coffee or tea powders within the receiving tank.

An extracting apparatus for extracting a beverage liquid from an extraction target includes an extraction container including a neck portion with an opening and a trunk portion and configured to store the extraction target and a liquid, a filter arranged on the opening of the neck portion and configured to restrict leakage of the extraction target, and a driving unit configured to change a posture of the extraction container from a first posture in which the neck portion is located on an upper side to a second posture in which the neck portion is located on a lower side.

A coffee maker and a coffee preparation method thereof are disclosed, the coffee maker includes: a stator frame; a grinding chamber including a cavity is mounted on the stator frame, and a cover; the cavity is covered by the cover to enclose a grinding cavity, a bottom of the grinding cavity having a beverage outlet communicated with the beverage cavity; a grinding device including a grinding knife tackle disposed in the grinding cavity, and a motor disposed outside the grinding cavity to drive the grinding knife tackle to rotate; a coffee strainer, circularly arranged on a peripheral of the grinding knife tackle; a lower end of the coffee strainer abuts a bottom wall of the grinding cavity to separate the grinding cavity into a grinding bean cavity and a beverage cavity disposed on the periphery of the grinding bean cavity.

Aspects relating to a method and apparatus for venting a heater tank of a beverage forming apparatus using a vent valve that is opened and closed based on an operation to move a brew chamber lid between an open lid position and a closed lid position are provided. In one aspect, the vent valve may be positioned on a vent line distinct from a delivery line that delivers heated liquid from the heater tank to the brew chamber. In another aspect, at least a portion of the delivery line may extend downwardly from the top of the heater tank to a location between the top and the bottom of the heater tank. In another aspect, the at least a portion of the vent valve may be attached to the handle for movement with the handle.

A method and apparatus for venting a liquid supply of a beverage machine, e.g., by permanently open orifice and/or pressure relief valve. The orifice may always vent a heater tank, even while liquid is delivered to the tank by a liquid pump and/or while the tank is pressurized by an air pump to deliver liquid from the tank. A filter may be positioned between a heater tank and orifice and/or air pump. The pressure relief valve may be positioned between the liquid pump and the inlet side of the heater tank, e.g., so relatively cool water is released by the pressure relief valve when open.

A machine for dispensing beverages includes a pod including at least two cavities each cavity containing a volume of ingredients forming part of a composition of the beverage, the machine further including an air injection device configured to supply at least two volumes of air in a synchronized manner, the at least two volumes of air being adapted respectively to the volumes of ingredients in the at least two cavities, the injection device including an air pump including two chambers and two pistons slidably mounted respectively in the two chambers, and an actuator configured to actuate the two pistons in a synchronized manner.

An extracting method of extracting a beverage liquid from an extraction target includes a pressure reduction step of switching an interior of an extraction container in which the extraction target and a liquid are stored from a first air pressure to a second air pressure lower than the first air pressure, and an extraction step of extracting the beverage liquid from the extraction target. The first air pressure is an air pressure at which the liquid at a predetermined temperature does not boil, and the second air pressure is an air pressure at which the liquid that does not boil at the first air pressure boils. The switching from the first air pressure to the second air pressure is done by releasing the air pressure in the extraction container.
