Abstract (en)
[origin: WO2018162824A1] The invention relates to a device (1) for brewing matter (30), comprising a rotary drum (2) and at least one shaftless screw (3) which extends inside the drum (2), being mounted in a rotatable manner with respect to the drum (2). Each shaftless screw (3) is formed by one or more coaxial helical windings (41) and each winding (41) comprises a helical support (5) of pitch P that is formed by a helically wound elongate body with a constant cross section along at least a part of its length, and a helix (6), known as a secondary helix, disposed around and carried by said support (5), wherein the outside diameter DeS of the support (5) is less than or equal to 1.5 times the pitch P of the support (5), wherein the secondary helix (6) comprises a plurality of turns (71, 72) with a pitch identical to the pitch of the helical support (5), said turns (71, 72) of the secondary helix (6) forming a surface that develops radially with respect to the longitudinal axis of the support (5), each turn (71, 72) of the secondary helix (6) being inscribed in a cylinder of diameter De, this diameter De of said cylinder being greater than or equal to 2.5 times the pitch of said support (5).
