A cold brew coffee brewing machine is provided. The cold brew coffee brewing machine may have an upper chamber and a generally identical lower chamber wherein the upper chamber and the lower chamber may be, for example, common mason jars. A filter unit may be secured between the upper chamber and the lower chamber when the coffee brewing machine is in use. A hand pump may be connected to the filter unit and may provide air pressure to the upper chamber. The lower chamber may then be secured to the filter unit and the entire device inverted. Both gravity and air pressure created by the hand pump may be used to force the water through the filter unit so that the drinkable coffee enters the lower chamber.

A device for extracting a substance to be brewed comprising: an extraction compartment in a first and a second portion, movable relative to the first portion to switch the compartment between a closed position and an open position; a linking device between the first and the second portion, comprising a holder with a first link so configured as to produce a rotation of the holder relative to the first portion, and a second link relative to the second portion, and the device comprises an articulation joint so configured as to successively produce, during a rotational motion of the holder about the first link in a first direction of rotation, a first tilting of the second portion in the first direction, then a second tilting of the second portion in a second direction opposite the first direction.

A filter capsule for secondary filtration of extracted coffee is provided, where the filter capsule comprises a housing and at least one filter element or consists thereof. The housing comprises a bottom, at least one side wall and at least one cover or consists thereof, the at least one filter element being disposed in an interior space of the housing. Coffee extracted on a brewing strainer can be subjected to a secondary filtration so that suspended particles and emulsified oils of a specific size are separated from the coffee by the filter element of the filter capsule and a new type of coffee is produced. The use of the filter capsule for secondary filtration of coffee is therefore proposed.

Fast-uncoupling shower screen for espresso coffee machines having a circular support dish provided with holes, a flow restrictor disposed under the circular support dish, and an elastically deformable retention element, whereto the flow restrictor is fitted in snap-in coupling mode because of the elastic deformability of the retention element.

A coffee machine has a body, a dispensing unit, a conduit, a supply and heating device, a filter holder, fast coupling/uncoupling means to couple the filter holder under the conduit, a control unit, a presence sensor to detect the presence of the filter holder under the conduit, and a switch to enable the passage of electrical current towards the supply and heating device and towards the dispensing unit when the presence sensor detects that the filter holder is uncoupled from the fast coupling/uncoupling means. The control unit has a timer to manage the opening/closing of the switch.

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.

A pod assembly for use in a beverage machine is provided. The pod assembly includes a container and a filter disc that is detachably coupled to the container. The container includes a base, a side wall having a lower rim coupling the side wall to an outer perimeter of the base, and a flange coupled to an upper rim of the side wall and extending radially outward from the upper rim. The filter disc includes a central portion with multiple central openings, an inclined portion with multiple secondary openings, and an outer flange situated at a perimeter of the inclined portion and having a substantially square shape.

A coffee brewing apparatus which can prepare either hot or cold coffee extract having a filter body (8) and two reservoirs (14a and 14b). The filter body 8 is a hollow cylinder with male threaded ends (10a and 10b). A mesh filter (12) is affixed to interior of the filter body (8). Two self-supporting reservoirs (14a and 14b) have female threads (16a and 16b) near their ends. Coffee grounds (18) and either hot or cold water (20) are added to one of the reservoirs. The apparatus is then assembled by joining the cylinder's male threaded ends (10a and 10b) to both reservoirs' female threaded ends. The assembled apparatus is then allowed to sit for a period of time, while coffee flavors are extracted into the water. The entire apparatus is then inverted, the mesh filter (12) removes the coffee grounds from the coffee extract (22), and the coffee extract is collected in the now lower reservoir (14a). The apparatus is disassembled for consumption of the extract, and is cleaned and reused.

A coffee machine includes: a filter holder suitable for containing at least one coffee dose; a dispensing unit with dispensing nozzles suitable for sending a flow of hot water on the coffee dose; a water system provided with a pump to supply pressurized water towards the dispensing nozzles; a heater to heat the water to be supplied to the dispensing nozzles; a dispensing valve to enable/disable the supply of hot water towards the dispensing nozzles; a pre-infusion valve installed upstream the dispensing valve; and a control unit comprising actuation means to actuate the pre-infusion valve. The pre-infusion valve is a two-way electrovalve of programmable proportional type.

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.
