A device () for pressing a dose of ground coffee powder includes a filter holder cup () having a filter () for depositing the dose of ground coffee powder, an attaching support () in which the cup () is separably attached, a grinder () for coffee beans including a slide () for dispensing ground coffee having an outlet () positioned above the mouth () of the cup (), a pressing piston () for pressing the dose of ground coffee powder present in the filter () mounted in the cup (), and a lifting mechanism for lifting the pressing piston () in a position above the outlet () of the slide ().

Device for pressing a dose of ground coffee powder

A control unit, a pump for supplying infusion water, a boiler for heating the infusion water, an infusion unit, a coffee mill, and a user interface including a selector for a beverage and/or a ground coffee dose. The coffee mill has a hopper for coffee beans, a rotating and a non-rotating grinder, a motor for directly or indirectly driving the rotating grinder, all with capability to adjust the distance between the grinders. A first sensor detects a number of turns and/or speed of the motor and/or of the rotating grinder. A second sensor detects a distance between the grinders. The control unit stores an algorithm for calculating a correct dose of ground coffee, configured to receive the value of ground coffee selected and the distance between the grinders to automatically generate the number of motor turns necessary to obtain the correct dose of ground coffee.

A milk frother () including a container having a chamber () for containing milk, a mixing chamber () equipped with an external dispenser () for dispensing the milk, a connecting channel () for connection between the containment chamber () and the mixing chamber (), a transfer impeller () for transferring the milk from the containment chamber () to the mixing chamber, a mixing impeller () provided in the mixing chamber (), and disconnectable connector () for connecting the transfer impeller () and the mixing impeller ().

Milk frother and coffee machine that incorporates such a milk frother

The coffee machine () comprises a brewing cylinder (), a movement system of the brewing cylinder () comprising a nut screw () engaged with a motorised screw (), and elastic means () compensating the mechanical backlash between the threads of the screw () and of the nut screw ().

Coffee machine with improved movement system of the brewing cylinder

A coffee machine including a controller, a boiler for heating a flow of infusion water, a movable infusion unit having an open infusion chamber connected to a dispensing line for dispensing the coffee infusion and having an ejection piston slidably supported therein in the infusion chamber, a supply line for supplying said flow of infusion water to the infusion unit, a closing piston engageable for closure of the infusion chamber. The controller can subject the infusion unit, prior to execution of the infusion process, to a first course of translational movement for closure of the infusion chamber by the closing piston, and to subject the infusion chamber and/or the ejection piston, following execution of the infusion process, to a second course of translational movement, for compression of the load of spent coffee grounds against the closing piston and for drainage of the liquid contained therein.

Device for heating and emulsifying beverages includes a pump (), an air and water meeting zone (), a device for producing steam, and a first conduit () for steam mixed with air that communicates with a steam wand () adapted to be immersed into a beverage () to be heated and emulsified. The device for producing steam includes an instant steam generator (). The meeting zone () is positioned before the instant steam generator ().

Device for heating and emulsifying beverages

An automatic machine to deliver a beverage containing caffeine includes a water container, a possible pump, a filtering element to contain, during use, a powdered mixture, a main pipe that connects the container to the filtering element, and a heating element, associated with the container and/or with the main pipe, able to be selectively activated to heat the stream of water delivered from the container toward the filtering element in order to infuse the powdered mixture.

Automatic machine to deliver beverages

The coffee machine () comprises a coffee dispenser having a support (), a first spout () and at least a second spout () for dispensing coffee, and a mechanism for connecting the first and at least second spout () to the support () configured to adjust the position of the first spout () and at least a second spout () in the direction of the width (L) and at the same time of the height (A) of the coffee machine ().

Coffee machine with improved coffee dispenser

A filter for a coffee machine comprises a cup-shaped body () for containing coffee powder, having at least a bottom wall () having an opening (); a filtering wall () placed in the cup-shaped body () upstream of the opening () and removably associated with the cup-shaped body (); a seal () placed at least between one edge () of the filtering wall () and the cup-shaped body (); a tightening member () active on the filtering wall () and on the seal () so as to reversibly fix said filtering wall () and said seal () to the cup-shaped body (); said tightening member () comprising a tubular element () connected to the filtering wall () and to the seal () and arranged through the opening (); said tubular element () being directly constrained to the cup-shaped body () by means of a bayonet-type connection.
