A coffee grinding apparatus includes a removable holder assembly having first and second arms that are spaced-apart from one another to define an open receiving area therebetween. The arms each include upper and lower tabs that extend inwardly into the open receiving area first and second distances, respectively. The first and second distances of the upper and lower tabs are configured to retain and support portafilter assemblies of various sizes for filling with coffee grounds using the coffee grinder apparatus. Another holder assembly for use with the coffee grinding apparatus may include opposed abutment surfaces for engaging inner and outer surfaces of a cup portion of various sized portafilter assemblies. Each disclosed holder assembly is configured to attach to a pedestal portion of the coffee grinding apparatus in use, and can be stored in a support base of the coffee grinding apparatus when not in use.

A coffee dispenser comprises an inlet for receiving ground coffee, a ground coffee holder that receives ground coffee from the inlet, and a porta filter carriage for receiving a porta filter. The porta filter carriage is movable relative to the ground coffee holder between a closed position and a dispensing position. When a porta filter is received in the porta filter carriage, movement of the porta filter carriage from the closed position to the dispensing position causes coffee to be dispensed into the filter basket. Movement of the porta filter carriage from the dispensing position to the closed position causes a scraping action to occur across the coffee disposed in the filter basket, thereby removing excess coffee from the filter basket.

Filter holder for espresso coffee machines having a cup-shaped body of circular profile, suitable for internally housing the filter, as well as a pouring device of the beverage disposed under the cup-shaped body and provided with at least one pouring spout, the filter holder being provided with connections for connecting the pouring device to the cup-shaped body, wherein the connections enable a bayonet coupling between the pouring device and the cup-shaped body.

A system for detecting the presence of a filter holder in a dispensing assembly of a coffee machine includes: a ring with an internal groove, a filter holder with a tab coupled with the groove and a proximity sensor. The groove has a semi-annular shape and is configured in such a way to receive the tab of the filter holder in bayonet coupling mode, wherein the filter holder is translated and rotated. The ring has a rotation stopper suitable for stopping the rotation of the filter holder in the ring in a stop point. The proximity sensor passes through the ring and finishes in the stop point of the groove of the ring.

The present invention provides a coffee tamper, comprising a casing. A driving device is arranged on the inner top of the casing, connected to a tamping device and used to drive the tamping device to press down and move up. The tamping device is used to press down a container filled with coffee powder and comprises a main shaft, the driving device is connected to the upper end of the main shaft, and a tamping head is connected to the lower end of the main shaft and can be pressed into the container; and in one of embodiments, a container pressing head is sleeved on outside of the tamping head and has an outer cover sleeved on outside of the tamping head, the lower edge of the outer cover is located on the same horizontal plane and presses against the upper edge of the container, and the tamping head can move up and down relative to the container pressing head. The present invention provides a novel coffee tamper, which can overcome defects of existing equipment, apply uniform pressure on coffee powder and make flat coffee powder.

There is provided an aeration device including an interchangeable aeration element having needles arranged in an aeration pattern, a slider including the needles, a slider guide element engaged with the slider, a slider spring element biased to position the slider in an undeployed position, wherein the slider is displaced in a downward direction away from the top end of the aeration device frame towards the bottom end of the aeration device frame when a user applies an operating force to the slider, wherein the slider spring element applies a return force on the slider encouraging the slider to return to the undeployed position, and wherein, when the slider is in a fully deployed position at a maximum displacement from the top end of the aeration device frame, the plurality of puck aeration needles extend passed the bottom end of the aeration device, and a method of using the aeration device.

A brewer system includes a reservoir, a steep chamber movable relative to the reservoir and positioned over a mouth of the reservoir, and a filter tape positioned between the chamber and the reservoir. Brewing substance and water are added to the chamber to form a brewed beverage that passes through the filter tape and into the reservoir through the mouth.

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.

Methods, apparatus, and system to distribute or compact coffee grounds, such as to form a puck in a portafilter. The methods, apparatus, and system may be used to compact coffee grounds wherein a resulting puck of coffee grounds in the portafilter has an even level, a uniform and or continuous density distribution, results in no or reduced formation of channels, no or reduced squirting of extracted coffee, and results in consistent and repeatable results. The methods, apparatus, and system may be used to form multiple layers in a puck, for use in preparing layered espresso.

A device for preparing coffee by manual brewing includes: a filter holder for receiving a filter insert with ground coffee; a holder in which the filter holder is inserted; a vessel arranged under the filter holder into which the brewed coffee can be filled; a drain arranged on the filter holder; and a closure element arranged on the drain for opening and closing the drain. An actuating element for the closure element is provided on the filter holder by which the closure element can be moved between an open position and a closed position independently of the vessel.
