Definitions

  • the present invention concerns the field of processing grapes and the like, i.e. for fruit with grapes or berries.
  • the invention concerns a crushing device.
  • Such crushing devices generally comprise a support frame delimiting a crushing cavity at which the berries or grapes to be opened are poured.
  • a crushing assembly comprising at least a first cylindrical roller, formed by a plurality of cylindrical modules arranged in succession to each other, and at least a second cylindrical roller, also formed by a plurality of cylindrical modules arranged in succession to each other, which are adapted to cooperate for crushing the berries or the grapes and for the consequent opening thereof.
  • the first roller and the second roller are arranged at a non-zero distance from each other so as to define an interspace, and each roller is mounted on a drive shaft that moves the rollers in rotation.
  • the first roller and the second roller can be driven in rotation in reciprocally opposite directions.
  • the grapes or berries poured into the crushing cavity are then compressed between the first roller and the second roller as they pass in the interspace defined between them and open up.
  • the cylindrical surfaces of the rollers define a bridge effect for the berry or grape that continues to bounce between the rollers and fails to enter inside the interspace defined between the rollers themselves so as to be compressed and opened.
  • An object of the present invention is therefore to solve such a drawback of the prior art.
  • a further object is to achieve such objectives in the context of a rational, effective and affordable solution.
  • the invention makes available a crushing device, particularly for opening the grapes or berries of grape and the like, comprising:
  • each roller has along its longitudinal development (i.e. its development in a direction parallel to the axis of rotation of the drive shaft to which it is associated):
  • the invention makes available a particularly effective and reliable crushing device.
  • the crushing device makes it possible to avoid the occurrence of the "bridge" effect described above, i.e. it is particularly effective and reliable in trapping the grapes or berries inside the interspace and therefore in crushing and consequent opening of the same.
  • a further aspect of the invention provides that the first (cylindrical) section and the third section can have an equal length (i.e. development along the longitudinal development of the roller).
  • the invention provides that the first (cylindrical) section and the third (cylindrical) section can each have a length comprised between 0.2 times and 0.7 times the length of the second (conical) section, for example preferably comprised between 0.25 and 0.6 times the length of the second section, for example a length substantially equal to 0.3 times the length of the second (conical) section.
  • said interspace defined between (the outer surfaces of) two adjacent rollers i.e. two flanked and consecutive rollers, with respect to said flanking direction
  • said interspace defined between (the outer surfaces of) two adjacent rollers can have a constant size (with respect to said flanking direction) along (a direction parallel to) the longitudinal development of the rollers (i.e. along a direction parallel to the axes of rotation of the drive shafts).
  • the crushing device is configured to ensure that in each section of the interspace the grapes or berries are actually crushed and opened, avoiding that larger sections of the interspace which can allow the berries to cross the interspace without being crushed between the adjacent rollers may be present.
  • each roller may comprise a plurality of first sections, a plurality of second sections (each of which is derived, seamlessly, from a respective first section) and a plurality of third sections (each of which is derived, seamlessly, from a respective second section).
  • each roller can comprise a plurality of modules, for example homologous to each other, each of which has a tubular body that makes available along its longitudinal development (i.e. its development parallel to said axis of rotation of the drive shaft) one of said cylindrical first sections, one of said conical second sections, and one of said cylindrical third sections (i.e. a respective cylindrical first section, a respective conical second section that is derived from said respective first cylindrical section, and a respective cylindrical third section that is derived from said respective second conical section).
  • modules for example homologous to each other, each of which has a tubular body that makes available along its longitudinal development (i.e. its development parallel to said axis of rotation of the drive shaft) one of said cylindrical first sections, one of said conical second sections, and one of said cylindrical third sections (i.e. a respective cylindrical first section, a respective conical second section that is derived from said respective first cylindrical section, and a respective cylindrical third section that is derived from said respective second conical section).
  • the roller is modular, i.e. it can be composed as required by combining a variable number of modules, quickly and easily.
  • each roller has an overall repetitive and variable architecture along its longitudinal development, and two adjacent rollers are even more effective in drawing the berries or grapes inside the interspace, obviating the aforesaid bridge effect.
  • each roller for example each module of the roller, can have an outer surface (by means of which it is adapted to contact the berries or grapes, made available overall by the outer surfaces of the modules that compose it) that is fluted or knurled or provided with grooves. Thanks to this solution, each roller has a surface capable of exerting a particularly effective grip on the berries or grapes, and the crushing device is therefore even more effective and reliable in the operations of crushing and opening the berries or grapes.
  • a further aspect of the invention provides that the outer surface of each roller, for example the outer surface of each module of the roller, may have a plurality of first grooves and a plurality of second grooves different from the first grooves.
  • each roller for example each module of the roller, is shaped in such a way that it is particularly effective in the gripping effect of the berries or grapes.
  • each first groove can have a variable size from the (i.e. from a respective) cylindrical first section to the (i.e. to a respective) cylindrical third section.
  • the rollers make each available a variable and shaped surface that allows to prevent the berry or grape from slipping into contact with the roller without being intercepted by the same and drawn within the interspace where it is crushed and opened.
  • each second groove may have a larger cross-section than the cross-section of a first groove.
  • the outer surface of the roller has grooves of variable sizes that allow to intensify, i.e. make even more effective, the grasping effect on the berries or grapes and make even more effective and repeatable the crushing operations of the crushing device.
  • a further aspect of the invention provides that consecutive adjacent modules of each roller can be arranged reciprocally symmetrically (with respect to an imaginary axis of symmetry orthogonal to the axis of rotation of the drive shaft to which the roller is associated, i.e. parallel to the flanking direction).
  • the adjacent rollers are able to define an interspace provided, along a direction parallel to the axes of rotation of the first drive shaft and of the second drive shaft, with successive reciprocally transverse sections that allow the crushing device to be overall further particularly effective in its action on the berries or grapes.
  • each module of a roller can be facing onto a respective module of the adjacent roller and aligned thereto (with respect to said flanking direction), and further arranged symmetrically to the other with respect to an (imaginary) axis of symmetry parallel to the flanking direction of the drive shafts (i.e. orthogonal to the axes of rotation thereof).
  • said modules of two adjacent rollers that are respectively facing and aligned are oriented in the space rotated by 180° with respect to each other with respect to an imaginary axis parallel to the flanking direction of the drive shafts (i.e. an imaginary axis orthogonal to the axes of rotation thereof).
  • the crushing device may comprise a drive mechanism configured to drive in rotation each drive shaft about its own axis of rotation, the drive mechanism being further configured to rotate adjacent drive shafts (with respect to flanking direction) at different rotation speeds (i.e., to rotate adjacent rollers at different rotation speeds, for example the one at half the speed of the other).
  • the crushing device is even more effective in avoiding this undesired bridge effect.
  • the crushing device thanks to this feature is particularly effective in drawing the berries or grapes through the interspace defined between two adjacent rollers.
  • This differentiated rotation speed between the adjacent rollers makes it possible to obtain, in addition to the crushing of the berry or grape, the complete opening of the skin, i.e. a greater exposure of the inner surface of the skin to the outside, allowing to obtain a greater separation of the pulp and of the juice from the skin.
  • This particular effective action of the crushing device also allows to obtain multiple advantages in the subsequent processing phases, especially in the case of white grapes the juice contained in the berry (must) is extracted more quickly, making the subsequent crushing process more efficient with less oxidation, while in the case of red grapes a better extraction of the colour from the skins can be achieved in the subsequent fermentation phase for the production of red wines.
  • the invention also makes available a method for crushing berries or grapes, e.g. of grapes and the like, which provides for:
  • a crushing assembly associated with the crushing cavity comprising: - a plurality of drive shafts, reciprocally parallel and flanked at a non-zero distance from each other, each of which is arranged in the crushing cavity and movably associated in rotation with the support frame about a respective axis of rotation,
  • each roller can have along its longitudinal development a cylindrical first section, a conical second section which is derived from the cylindrical first section and a cylindrical third section which is derived from the second conical section.
