Meanwhile, reduction in water flow caused by the mixing of the filter materials and the caking of the filter material is also solved.

A press device for pressing powders in a container is provided. The press device has a compact structure that can be operated by one hand of a user and comprises an operation element, a pressing element, a body and at least one elastic element, wherein the at least one elastic element is provided between the operation element and the pressing element. A surface of the pressing element is urged by the force provided by the at least one elastic element to press the powders in the container.

Filter (1) for preparing coffee or an infusion for single use, of the type that comprises a tub (6) for pouring a liquid over, usually water, and whereby, when considered in use position, a compartment (4) is provided at the bottom of the tub (6) which is partly delimited by means of water-permeable layers and in which coffee or herbs are provided, whereby the tub (6) is made of an essentially cylindrical or conical jacket (6′), the lower edge of which is provided with an inwardly oriented supporting edge (5) which transitions into a cylindrical compartment (4) with perforated base, whereby the inwardly oriented supporting edge (5) serves as a supporting edge for the filter (1) when said filter is placed on a cup (11), characterised in that at least the outside surface of the supporting edge on the outside is provided with a microroughness Ra between 10 and 200 μm.

A filter assembly that includes a receptacle, filter, and filter holder. The receptacle has an inside surface defining an open-ended first through-channel. The filter is positioned inside the first through-channel and configured to produce a filtered liquid by filtering particulates each larger than a predetermined size from a liquid. The filtered liquid exits the filter through an outlet opening of the filter. The filter holder removably couples the filter to the receptacle. A holding area configured to receive the liquid is defined in the first through-channel above the filter holder and between the filter and the inside surface of the receptacle. The filter holder includes an open-ended second through-channel in fluid communication with the outlet opening and configured to receive the filtered liquid from the outlet opening. The second through-channel is configured to be in fluid communication with an interior of a container and to provide the filtered liquid thereto.

A cold brew coffee maker has a water cleaning system connected to a water source; a water pump connected to the water cleaning system, and connected to the pressurized-water storage tank for storing a filtered water in the tank; and a coffee brewing module connected to the pressurized-water storage tank and including: a detachable brewing cup detachably secured to a fixing bracket, a solenoid valve formed between the brewing cup and the pressurized-water storage tank, and a switch panel formed in the main body; whereby upon starting of the pump to suck and filter a feed water, a filtered pressurized water less than 30 degrees centigrade will be delivered into the tank and upon actuation of the switch panel to open the solenoid valve, the pressurized water will be ejected into the cup for brewing coffee.

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.

A coffee machine for wirelessly driving a coffee cup holder to rotate comprises a machine body and a cup holder; the cup holder comprises a base, a cup holder and a driving motor, wherein the base is internally provided with a driving motor, and the output shaft of the driving motor is sleeved with the cup holder; the upper part of the machine body is provided with a support, the support is provided with a sprinkler head, the sprinkler head is provided above the cup holder, and the height difference between the sprinkler head and the cup holder is capable of accommodating a coffee cup in which a coffee filter cup is placed; the machine body is provided with a charging coil, the cup holder is provided with a power receiving coil, and the installation position of the power receiving coil corresponds to that of the charging coil.

A method of brewing hot beverage with an electric hot beverage brewer (20) with a duty cycle modulated DC voltage dispense pump (44) with an inlet (46) connected to a de-aerator (24) and beneath a lower limit and an outlet (48) located above an upper limit the surface a hot water tank (22) is finely controlled by a high frequency pulse-width, modulated, square power input voltage (FIG. 2) with a duty cycle controlled in accordance with predetermined profiles stored within a controller (28) to selectively change the flow rate out of the pump onto a distribution dome (50) during a dispense period of a brew cycle to achieve optimum brewing of different types of beverage ingredients and varieties of the different types and to selectively change the spray pattern of hot water onto the ingredient (53) within the basket assembly (52) between vertical and acute angles including acute angles that pass hot water into a bypass gap (56).

A drip bag includes a bag main body formed of a water permeable filter sheet and hooking members made of a thin plate-like material on two opposite outer surfaces. Each hooking member includes upper bonded, central, and a pair of arm portions from the central to toward the upper bonded portion, and a pair of hooking portions. The arm portions are mutually spaced with a bag main body width center line between them. Each hooking portion extends downward in and are not bonded onto the bag main body. Each arm portion can be pulled up from the bag main body at an upper part, and has a fixed side on the bag main body at a lower part. The fixed side is inclined relative to a bag main body width direction. A bag main body opening portion opens wider even when a cup opening diameter is small.
