Brewing device for preparing beverages

A brewing device for preparing beverages, the brewing device comprising:

• a brewing chamber having a tubular body extending along a longitudinal axis thereof, the brewing chamber delimited by an opening for loading/unloading a brewing material at one end and a piston slidably mounted in the brewing chamber at an end opposite the one end,
• wherein the tubular body is stationarily supported by a frame of the brewing device;
• and
• an electronic control unit that controls movement of the piston to cause the piston to move along the longitudinal axis among a loading configuration, in which the brewing material is loadable in the brewing chamber, a compression configuration, in which the brewing material is compacted by the piston in the brewing chamber, and an expulsion configuration, in which exhausted brewing material is extracted from the brewing chamber,
• wherein the electronic control unit is programmed to cause, in the loading configuration, the piston to lower from a higher position, corresponding to an initial loading configuration, to a lower position, corresponding to a final loading configuration, during the loading of the brewing material in the brewing chamber.

• an electronic control unit that controls movement of the piston to cause the piston to move among a loading configuration, in which the brewing material is loadable in the brewing chamber, a compression configuration, in which the piston compacts the brewing material in the brewing chamber, and an expulsion configuration, in which the piston extracts the exhausted material from the brewing chamber,
• wherein the electronic control unit is programmed to cause, in the loading configuration, the piston to lower from a higher position to a lower position relative to the higher position along the longitudinal axis,
• wherein the higher position corresponds to an initial loading configuration and the lower position corresponds to a final loading configuration;
• and
• a brewing fluid supply line that supplies a brewing fluid to the brewing chamber, the brewing fluid supply line comprising a channel formed in the piston that is fluidly connected to the brewing chamber, and a supply tube coupled to the piston that supplies the brewing fluid to the channel,
• wherein the supply tube has at least a fluid outflow portion that is coaxial with the channel, and the piston is mounted to slide relative to the supply tube during the movements among the loading configuration, the compression configuration, and the expulsion configuration.

A method for preparing beverages with a brewing device comprising a brewing chamber having a tubular body extending along a longitudinal axis thereof delimited by an opening for loading/unloading a brewing material at one end, and a piston slidably mounted in the brewing chamber at an end opposite the one end, wherein the tubular body is stationarily supported by a frame of the brewing device, wherein the piston is moveable among a loading configuration, in which the brewing material is loadable in the brewing chamber, a compression configuration, in which the brewing material is compactable by the piston in the brewing chamber, and an expulsion configuration, in which exhausted brewing material is extractable from the brewing chamber, the method comprising:

• setting a final position of the loading configuration based on the type of beverage to be prepared and/or a quantity of brewing material to be loaded in the brewing chamber;
• and
• controlling, by an electronic control unit, the piston to cause the piston to move along the longitudinal axis from an initial position of the loading configuration to the final position,
• wherein the higher position corresponds to the initial position and the lower position corresponds to the final position.

• loading brewing material into the brewing chamber;
• and
• controlling, by an electronic control unit, the piston to cause the piston to be lowered from an initial position of the loading configuration to a final position of the loading configuration, thereby enlarging the brewing chamber,
• wherein the piston is lowered from the initial position to the final position while the brewing material is loaded into the brewing chamber.
