Title (EN) DEVICE FOR BREWING MATTER, NOTABLY FOR BREWING MATTER TO BE FERMENTED
(FR) DISPOSITIF POUR LE BRASSAGE DE MATIERE, NOTAMMENT POUR LE BRASSAGE DE MATIERE A FERMENTER
Abstract:
(EN) 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).
(FR) Dispositif (1) pour le brassage de matière (30) comprenant un tambour (2) rotatif et au moins une vis (3) sans âme qui s'étend à l'intérieur du tambour (2) en étant montée rotative par rapport au tambour (2). Chaque vis (3) sans âme est formée d'un ou plusieurs enroulements (41) hélicoïdaux coaxiaux et chaque enroulement (41) comprend un support (5) hélicoïdal de pas P formé d'un corps allongé enroulé hélicoïdalement et de section transversale constante sur au moins une partie de sa longueur, et une hélice (6) dite secondaire disposée autour et portée par ledit support (5), en ce que le diamètre DeS extérieur du support (5) est inférieur ou égal à 1,5 fois le pas P du support (5) et en ce que l'hélice (6) secondaire comprend une pluralité de spires (71, 72) de pas identique au pas du support (5) hélicoïdal, lesdites spires (71, 72) de l'hélice (6) secondaire formant une surface se développant radialement par rapport à l'axe longitudinal du support (5), chaque spire (71, 72) de l'hélice (6) secondaire étant inscrite dans un cylindre de diamètre De, ce diamètre De dudit cylindre étant supérieur ou égal à 2,5 fois le pas dudit support (5).
