Abstract: A vending machine (1) comprises a brewing unit (7) provided with a brewing chamber (8) that is closable at the bottom portion thereof by means of a movable filter (9) adapted to retain the brewing residues, and further comprises actuator means (11) adapted to cause said filter (9) to displace from a first brewing position, in which said filter (9) is associated to said brewing chamber (8) in a fluid-tight manner, to a second discharge position, in which said filter (9) is separated from said brewing chamber (8), and vice-versa. The vending machine (1) is characterized in that said actuator means (11) comprise cleaning means (24) interacting with said filter (9) to remove the brewing residues therefrom, said actuator means (24) actuating said cleaning means (24) when the filter (9) is in said second discharge position thereof.

Abstract: Beverage brewing device, in particular for brewing hot beverages such as coffee, tea, roasted-barley coffee, camomile tea and similar infusions, comprising substantially a brewing chamber (1), in which the substances needed to prepare the infusion are introduced through a mixing hopper (2), which is situated above said brewing chamber, and are mixed by compressed air being admitted thereinto as supplied by an air compression means (7), the device further comprising a removable filter (10) that closes the brewing chamber on the lower side thereof. The opening (5) connecting the mixing hopper (2) with the brewing chamber (1) is closed by an automatic valve (6), which is actuated by the compressed air supplied by said air compression means (7) via a delivery conduit (8). Very simple and rational technical solution.
