Embodiment Construction

[0027] exist figure 1The reference numeral 1 in it refers to an apparatus for preparing a coffee extract with a fine foam layer. The device is provided with at least one inlet 2 through which coffee extract can be supplied. Also, the device comprises a first outlet 4.1 and a second outlet 4.2 for dispensing coffee extract with a fine foam layer. In use, under each outlet 4.1 and 4.2 can be placed cups 5.1 and 5.2 to be filled with coffee extract (coffee cream) with a fine foam layer. It is also possible to place a cup under the two outlets 4.1 and 4.2 and thus fill one cup with two outlets.

[0028] The device comprises at least one liquid flow channel 6 extending from at least one inlet 2 to outlets 4.1 and 4.2. In use coffee extract flows from the at least one inlet along the liquid flow channel 6 to the first and second outlets 4.1 and 4.2. In this example the inlet 2 is provided with first and second spouts 8.1 and 8.2, each of which is arranged in such a way that when...

Abstract

This invention relates to an apparatus for preparing a coffee extract with a fine-bubble froth layer, provided with at least one inlet (2) to which coffee extract is supplied, at least one outlet (4.1; 4.2) for dispensing the coffee extract with the fine-bubble froth layer and at least one liquid flow path extending from the at least one inlet (2) to the at least one outlet (4.1; 4.2) and along which, in use, the coffee extract flows from the at least one inlet (2) to the at least one outlet (4.1; 4.2) while in the liquid flow path a liquid impact surface (12) is included and the at least one inlet is provided with at least one spout opening for generating at least one coffee extract jet which, in use, squirts to the liquid impact surface when the coffee extract is supplied to the at least one inlet. According to the invention, the impact surface (12) is provided with a roughened surface structure.

Description

technical field [0001] This invention relates to a device for preparing coffee extract with a fine-foam layer, which device is provided with at least one inlet for supplying coffee extract, at least one outlet with a fine-foam layer of coffee extract and from at least one inlet to at least one liquid flow channel of the at least one outlet along which, in use, coffee extract flows from the at least one inlet to the at least one outlet, comprising a liquid impingement surface in the liquid flow channel, and at least one inlet At least one spout for producing at least one jet of coffee extract which, in use, is directed onto the liquid impingement surface when coffee extract is supplied to the at least one inlet. Background technique [0002] Such a device is known from European Patent Application No. 0 878 158 . In this known device, the liquid flow path includes a receiving trough with upstanding side walls and a bottom, the bottom of which forms the impact surface so that ...
