A portable, battery-operated vacuum infusion machine includes a top container assembly with a compartment that houses an air pump, a battery, and a controller. The top container assembly couples to the top opening of a separate bottom container. When coupled together, the top and bottom containers are connected by flow holes superimposed by a filter in the top container. An air pump switched on or off by a controller exerts negative pressure in the bottom container by means of a suction port and induces liquid in the top container to enter the bottom container under pressure while the filter in the top container ensures that the infusion residue is separated from the liquid and only the prepared infusion has passage to the bottom container. The bottom container can be opened by means of removing the top container in order to allow for serving the prepared infusion.

A beverage extracting device including a vessel for receiving and mixing a powder material and hot liquid, a filter beneath the vessel, a gas pump that connects through a duct to the vessel for supplying pressurized gas into the vessel, and an outlet for extracted liquid at an outlet side of the filter which is opposite to the vessel, wherein the outlet connects to an outlet duct for the extracted liquid, wherein the duct for supplying pressurized gas into the vessel connects to a channel or channels within the vessel having outflow openings at a lower rim of the vessel to release gas into the vessel and stir the mixture inside the vessel from below in an upwards direction.

An autonomous beverage maker, system and method for fresh brewed coffee, tea, and other beverages, responsive to sensed demand or inputted command, makes an initial beverage extract concentrate in a turbulent manner under unpressurized conditions, and then a dilute/secondary extract under pressurized conditions and mixes the initial extract and dilute to complete a beverage batch, successive secondary extracts/dilutes being made as required or desired to meet flavor, strength, etc., successive batches being rapidly made as required to meet demand, maintain level, etc. A parameter or parameters within a receiving or dispensing container is/are autonomously monitored to determine level, demand for additional beverage, beverage age, and or/other information, and responsive to the monitored information or an inputted command, the beverage maker autonomously adapts the beverage making operation or executes predetermined steps, such as, but are not limited to, making more or fewer beverage batches, or signals to dispose of existing beverage.

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.

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.
