A cold-brew coffee brewing system has a brew tank assembly supported in an elevated position by a tank support structure. A fluid-permeable support structure is removable from below the interior volume of a tank body for accessing the interior volume to remove used coffee grounds. A swing arm assembly supported by the tank support structure facilitates convenient support and movement of the fluid permeable support structure under a load of used coffee grounds in the interior volume of the tank body. A cold-brewing method for preparing cold-brew coffee may use the cold-brew coffee brewing system.

A method and apparatus provides a coffee beverage having a reduced terpene content, where a brew chamber has a brew area A is provided and a volume of water is provided to flow through the coffee grounds in the brew chamber and out of the brew chamber to provide a coffee beverage, and where the flow rate of water provided through coffee grounds in the brew chamber is F and the ratio of F/A is about 0.15 cm/s or less.

A hollow cylinder (102) contains hot water for making a hot beverage, for example, coffee. The cylinder (102) has an inner wall (102a) extending along an axis (104) from an open upper end (102b) to an open lower end (102c) of the cylinder. A perforated closure (106) is releasably securable to the cylinder (102) to hold the coffee at the lower end (102c). A cap (110) carries a plunger (112) configured and arranged for sealing engagement with the inner wall (102a) of the cylinder (102). In use, the cap (110) is rotatable on the cylinder (102) about the axis (104) and is connected to the cylinder (102) by a helical formation. Rotation of the cap (110) on the cylinder (102) drives the plunger (112) towards the lower end (102c) of the cylinder (102) to press the hot water through the perforated closure (106) and the coffee held thereon and then into the vessel (118).

The invention relates to a high-pressure centrifugal intelligent fast filter drip coffee maker which includes an adjustable bracket and a centrifugal filter drip element. The adjustable bracket includes a bottom plate, a pillar fixedly disposed on the bottom plate, a first support plate, and a second support plate. The upper end of the pillar is provided with a cavity with an upward opening. A first motor, a lead screw, and a bearing are respectively arranged in the cavity. The lower end of the pillar is provided with a plurality of adjusting screw holes. The first support plate is fixedly connected to the adjusting screw hole by a bolt. A second motor is embedded in the first support plate. A main shaft of the second motor passes through the first support plate. The main shaft of the second motor is provided with a transmission gear. The centrifugal filter drip element includes a tank body, a rotating base, a cover, a water pump, a funnel and a water pipe. The high-pressure centrifugal intelligent fast filter drip coffee maker of the invention has advantages of having a simple and reasonable structure, being convenient to use, rapid brewing, safe and reliable, and good effect of brewing, etc. which effectively solves the problem of existing filter drip coffee makers making coffee slowly.

A coffee filter includes a metallic member having a flat portion in which tapered exit regions are formed that extend from the bottom of the flat portion to vertices interior to the flat portion. The flat portion is provided with a hole uniformity enhancement region between the top of the flat portion and the exit region vertices that are interior to the flat portion. The top of the flat portion is micro-machined to remove a part of the hole uniformity enhancement region to a predetermined depth into the hole uniformity enhancement region. Holes are formed in the top of the flat portion extending from the micro-machined top of the flat portion through the hole uniformity enhancement region to the vertices of the tapered exit regions. The predetermined depth of the micro-machined top of the flat portion is selected to prevent the micro-machined top of the flat portion from meeting the tapered exit regions to promote and maintain uniformity of the holes.

A coffee dispensing apparatus includes a base and an at least one nozzle. Further, base and nozzle are arranged such that the dispensed coffee flows via inner upstanding wall of a standard sized coffee container.

A professional coffee machine includes a supporting frame; a boiler; a preheater to prepare a coffee infusion having a first heat exchanger with the boiler to heat the supply water crossing the first exchanger to a first temperature T.sub.1 close or substantially equal to a second temperature T.sub.2 corresponding to the optimal temperature for a coffee infusion; a dispensing unit of the coffee infusion having a thermo-controlled heating element that brings the water released from the preheater to the second temperature T.sub.2 if T.sub.1 is lower than T.sub.2; a thermal insulator that mechanically constrains the dispensing unit to the frame; a heater for preparing a tea infusion or the like having a second heat exchanger with the boiler to heat the supply water crossing the second heat exchanger up to a third temperature T.sub.3 corresponding to the optimal temperature for preparing a tea infusion or the like.

An espresso coffee extraction device includes an extraction piston driving unit having an extraction piston that, when coffee particles are supplied to a two-way cylinder via a coffee bean grinder to extract espresso coffee automatically, descends and injects hot water into the coffee with a strong pressure, thereby generating coffee liquid. A two-way cylinder driving unit moves leftward/rightward, continuously extracts coffee via a coffee extraction filter unit, and discharges coffee remnants to the outside after the extraction when the extraction piston ascends. The extraction device enables fully automatic extraction of coffee having the same quality as espresso extracted by baristas manually. The extraction device can be used with various types of expresso extractors as the main device of various types of fully automatic espresso extractors for use in factories, coffee shops, restaurants, homes, and offices, thereby enabling anyone to use the same conveniently and extract high-quality coffee.
