Disclosed is brewing extraction equipment, including a cylinder, a piston, a pressure rod, a connecting rod, a kettle body, a first one-way valve, a second one-way valve, a water separator and a powder bowl. The pressure rod comprises a pressure rod head and a pressure rod handle, the kettle body comprises a water tank, a first pipe and a second pipe. The connecting rod is connected to the pressure rod head, the pressure rod head is connected to one end of the piston, the piston is arranged inside the air cylinder, the water tank is connected to the bottom of the cylinder via the first pipe, the first one-way valve is located inside the first pipe, the air cylinder is further connected to the water separator via the second pipe located at the bottom thereof, and the second one-way valve is located inside the second pipe. The brewing extraction equipment enables a user to obtain huge liquid pressure and liquid pressure intensity by easily applying a force, so as to extract high-quality espresso coffee. And the equipment is small, lightweight and detachable, and is easy to carry.

This inventive system comprises at least a container (carafe), a bottom piece (Mop), and a top piece (plunger). In one embodiment, the top piece has a single hollowed handle into which the handle of the bottom piece inserts. In another embodiment, the top piece has several handles and/or legs that attach to the periphery of the base of the top piece. In this iteration, the handle of the bottom piece (Mop) inserts through a hole in the center of the base of the top piece (plunger).

Embodiments of an liquid filtering device are provided including a plunger to be inserted into an container containing a liquid that can have vertical inner walls oriented parallel to a vertical axis of the container. In some implementations, the plunger includes a first surface with a seal situated at an edge of the surface. The seal is adapted for sealing against the inner walls of the infusing container as the plunger moves within the container. The plunger also includes a second surface extending from the first surface and defining a second chamber.

A brewing unit for an espresso and coffee machine includes a frame structure, a hand lever which is mounted on the frame structure so as to be rotatable about an axis of rotation, and a brewing piston element which is operatively connected to the hand lever by means of a lever mechanism, whereby the brewing piston element, coupled to the movement of the hand lever, is movable between a first position and at least one second position along a vertical axis. The brewing piston element includes a distributor sieve which, in the second position of the brewing piston element, and together with a filter support which can be inserted into a holding device, delimits a brewing chamber, and hot pressurized brewing water is able to be introduced into the brewing chamber through the distributor sieve; the brewing piston element also includes a piston rod to which the distributor sieve is connectible. The brewing unit further includes locking means which are designed to hold the brewing piston element in at least one adjustable position along the vertical axis.

An improved French coffee press apparatus, system, and method that utilizes a locking ring to engage with a locking base that can be removed from the carafe, along with any coffee grounds. The locking ring is connected to the pressing rod, which also includes a filter system above the locking ring. The pressing rod fits through an opening in the carafe lid, and the carafe lid secures the liquid inside the carafe. The combination of the filtering system assists in the filtering and capture of any coffee grounds into the locking base for cleaning, and the locking ring assists in the removal of the locking base.

Embodiments of the present disclosure relate generally to espresso makers that brew beverages without power. The machines are designed to work under manual power, delivering hot water to the brew portion of the machine from an integrated hot water source. The machines may be mounted on aircraft trolleys for seat-side coffee and/or espresso service.
