The present invention discloses an inner pipe for a liquid heating apparatus, including a hollow pipe body made of a metal or an alloy, where a pipe wall thickness of the pipe body is 0.3-1.0 mm; through a machining method of rolling or pressing, a spiral diversion structure is machined on an inner peripheral wall of the pipe body along an axial direction of the pipe body, so that the spiral division structure is formed to extend along the axial direction of the pipe body. The present invention further discloses a liquid heating apparatus and a manufacturing method therefor. The liquid heating apparatus includes the inner pipe and the outer pipe; a heating assembly is disposed on the outer peripheral wall of the outer pipe.

A brewing module for preparing a brewed drink from a portion capsule, includes a first brewing module part and a second brewing module part, which is movable relative to a housing between a first brewing module part position and a second brewing module part position. An operating element is able to be brought manually from a first into a second operating element position, from which a movement is transmitted via a transmission mechanism into a movement of the second brewing module part. The transmission mechanism includes a cam disc that is rotatably mounted on the housing by the operating element wherein the second brewing module part is displaceable along a displacement stretch, which is fixed with respect to the housing, from a first brewing module part position into the second brewing module part position by way of the cam disc being rotated by the operating element.

The present disclosure relates to the technical field of tea brewing devices, and more particularly, to a beverage brewing device. The beverage brewing device comprises a kettle body, a heating disc, and a tea-leaf basket. The heating disc and the tea-leaf basket are located in the kettle body and an air cylinder mechanism is fixed in the kettle body. A moving piston is arranged in an inner cavity of the air cylinder mechanism, and the piston is connected to the tea-leaf basket. The air cylinder mechanism is connected to an air pump, which is used for conveying a driving gas to the air cylinder mechanism. The piston is driven by the driving gas, thereby driving the tea-leaf basket to move in the kettle body. The air cylinder mechanism may automatically drive the tea-leaf basket to move up and down, achieving a simple structure and a low cost.

A method and apparatus for venting a liquid supply of a beverage machine, e.g., by permanently open orifice and/or pressure relief valve. The orifice may always vent a heater tank, even while liquid is delivered to the tank by a liquid pump and/or while the tank is pressurized by an air pump to deliver liquid from the tank. A filter may be positioned between a heater tank and orifice and/or air pump. The pressure relief valve may be positioned between the liquid pump and the inlet side of the heater tank, e.g., so relatively cool water is released by the pressure relief valve when open.

A modular brewing system is described for providing hot water and managing power to multiple brew tower modules using a single centralized boiler and power management module so as to limit the number of high-power circuits required in a coffeehouse or store. The boiler and power management module manages power of components of the centralized boiler assembly and any brew tower modules connected thereto, including the boiler heaters, the grinder motors, and the brew chamber heaters.

Heat transfer device (10) for heating a fluid or a fluid foam on demand comprising a path (30) through which the fluid or the fluid foam circulates and at least one layer (11) made of a thermally conductive material, the path (30) being in contact with the layer (11) in such a way that when the layer (11) is heated it transmits heat to the fluid or fluid foam as it circulates through the path (30), wherein the path (30) and the part of the layer (11) in contact with said path (30) are detachably configured so that they are made accessible for being cleaned.
