Abstract: A machine is described, for producing and delivering coffee-based beverages comprising: a heating boiler (1); a delivering assembly (3) comprising a solenoid valve (8) and second means for heating (7) and controlling (4) the water temperature; a filter-holder (5) removably connectable to the delivering assembly (3), comprising a filter (6) in which the powder of ground coffee is pressed; a hydraulic pump (2) for delivering water from the delivering assembly (3) through the powder of ground coffee, and connected to the heating boiler (1) and to the delivering assembly (3); a first pressure sensor (21) to detect the water delivery pressure and regulate the flow-rate of water depending on the pressure value detected by a second pressure sensor (26) arranged next to the solenoid valve (8) to measure the counter-pressure exerted by the powder of ground coffee.

Abstract: A device (10) is described, for grinding plant material in grains comprising: a containing hopper (11), configured to contain the plant material in grains to be ground and comprising a dragging mechanism to withdraw the plant material in grains from the hopper (11) and pour it into a containing tank (14); a load cell (13), to weigh a preset amount of plant material in grains in the containing tank (14); a collecting tank (16), comprising dragging means (26) to receive the plant material in grains or to allow the direct insertion into the device (10) of plant material in grains; a grinding chamber (17), comprising grinding means configured to receive the plant material in grains supplied by the dragging means (26) and grind it.
