A system to brew a liquid is provided. The system includes a container with a brewing chamber, which receives a volume of liquid to allow for extracting a soluble substance to form a solution within the liquid. A basket is configured to be received within an internal volume of the container, the basket includes an upper sealing region and an extended portion, the extended portion includes a plurality of holes therethrough. A lid rests upon an upper surface of the container, the lid includes a center hole therethrough, the upper sealing region of the basket rests upon the lid. An assembly is removably mounted with respect to the basket, the assembly comprises a pump, suction inlet, and a fluid outlet, wherein the suction inlet is fluidly connected to a suction of the pump and the fluid outlet is fluidly connected to the outlet of the pump.

A beverage brewer includes a pump, an intake tube assembly connected to an inlet port of the pump at a pump end, an outflow tube assembly connected to an outlet port of the pump at a pump end, a brewing material holder assembly configured to hold ground brewing material and arranged at an issue end of the outflow tube assembly, and a container volume configured to accommodate a container assembly, arranged at an issue portion of the holder assembly. A suction end of the intake tube assembly is arranged within an interior of the container volume. The pump is configured to draw fluid from within the container volume through the intake tube assembly and to issue the fluid into the holder assembly through the outflow tube assembly, thereby brewing a beverage in the holder assembly. The holder assembly is configured to issue the brewed beverage into the container volume.

This invention discloses an airlift pumping mechanism for a fluid container, which is intended to address the problem of decreasing efficiency of the pumping mechanism when the liquid level in the container is low in the prior art. For this purpose, the airlift pumping mechanism comprises an air compressor and a riser tube assembly, wherein the riser tube assembly is located in a fluid container, and the air compressor is in communication with the riser tube assembly for feeding the compressed air to the riser tube assembly so that the same flows upward through the riser tube assembly together with the fluid in the fluid container. The pumping mechanism is characterized by further comprising a sunken cavity downwardly extending from the inner bottom surface of the fluid container, wherein the sunken cavity is located between the air compressor and the riser tube assembly and is in communication with the air compressor and the riser tube assembly. Due to the downward extension of the sunken cavity from the bottom surface of the container, the submergence ratio of the pumping mechanism can be significantly increased, thereby greatly increasing the pumping efficiency of the pumping mechanism at various liquid levels.

A method for preparing cold coffee involves placing ground coffee in a maceration basket, which is mounted in a maceration tank, and subjected the coffee to maceration by recirculated flow of maceration fluid pumped under pressure by a circulating pump to a hydrating head mounted centrally to the maceration basket. Preferably the maceration basket is completely immersed in the maceration fluid. A device for preparing cold coffee is also disclosed, the device has a maceration tank, in which a maceration basket 1 for ground coffee is operationally mounted. The maceration basket is formed as a cylinder having a hollow center column dimensioned to receive at least a portion of the hydrating head. A circulating pump circulates the maceration fluid under pressure, from the maceration tank, via the hydrating head and the ground coffee batch disposed in the maceration basket back into the maceration tank.
