Embodiment Construction

[0011] In Figure 1, the brewing device is shown to basically comprise a brewing chamber 1, in which the substances necessary for the preparation of infusions, ie beverages, are added via a filling and mixing hopper 2, the filling and mixing The hopper 2 is located above the above-mentioned brewing chamber. This hopper 2 is itself fed through a feed nozzle 3 which is connected to at least one container (not shown) in which a substance to be brewed, such as ground coffee, is contained.

[0012] The device itself can of course be provided with a variety of different containers, each containing a different substance for brewing. Preferably, all these containers are aimed at the hopper 2 with their delivery nozzles. In addition, in the same hopper 2, the required hot water is conveyed through the pipe 4 in order to prepare the selected substance.

[0013] A duct 22 for ventilating the air outside the device is associated solely with the hopper 2 ; this prevents foaming when the s...

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.

Description

technical field [0001] The present invention relates to a brewing device for preparing beverages, especially hot beverages such as coffee, tea, roasted barley coffee, chamomile tea and similar brewed drinks and infusions, using compressed air to Substances for straining and mixing beverages. Background technique [0002] The various brewing devices described above are mostly known in the art and basically consist of a vertical cylinder into which powdery substance and water are introduced through a filling hopper mounted on above the cylinder and mixed-filtered with air fed into it under pressure. These devices make it possible to obtain beverages which are well homogenized and which can be more or less flavored or palatable and which can be more or less foamed according to the actual desire of the purchaser. [0003] Such a modulating device is described, for example, in Japanese Patent Publication JP-A-01-158592. The device disclosed in this Japanese patent offers the p...
