Definitions

  • the subject of this application is drainage channels, which extend along a path within a pneumatic membrane press, used for external drainage of the fluids obtained from pressing fruit, grapes and their by-products.
  • the pneumatic presses most widely used for pressing fruit, grapes and their by-products are normally made up of a semi-tubular, inflatable membrane of non-toxic material, fastened to the internal half-circumference of the drum, which pushes the product against the drainage channels arranged along a half-spiral path, see AT-A-350 913, or in a longitudinal, semicircular path, see DE-U-9 300 755, to the press drum.
  • the primary task of the subject of this application is therefore to eliminate the above inconveniences, by developing drainage channels whose construction and arrangement within the pneumatic press drum allow for a complete and effective self-cleaning action.
  • the drainage channels may extend, within the cylindrical casing, along a fully circular or fully spiral path, with one or more spires; in order to reach the drainage outlet, the fluid is therefore forced to travel a distance allowing it to acquire a velocity permitting thorough, continuous washing on the drainage channels, thus making it impossible for the processing waste to obstruct or jam the surface of the channels themselves during use.
  • Another purpose is to achieve an invention that combines the previous characteristics with equipment that is reliable and safe to use, as the manufacturing costs for this system are modest.
  • the number 3 is used to indicate the pneumatic press structure most widely used for pressing fruit, grapes and their by-products, which includes a frame 4 supporting a drum 5 , to which an inflatable tubular membrane 1 of non-toxic material is attached.
  • the drum 5 is made up of a cylindrical casing 2 , closed at both ends by a convex base 6 , inside which the end of the inflatable tubular membrane 1 is attached; on the cylindrical casing 2, near the drainage channels 3,1 with polygonal cross-section, extending along a fully circular path along the inner surface of the cylindrical casing 2, are holes 7 connected to a drainage hose 8.
  • figure 5 illustrates another applicable solution in which the drainage channels 3,2 , with polygonal cross-section, extend along a fully spiral path, with one or more spires, along the internal surface of a cylindrical casing 2 .
  • figure 7 illustrates another applicable solution in which the drainage channels 3,3 , with polygonal cross-section, each extend within a fully circular extruded compartment 9 , also with polygonal cross-section, build on the internal surface of a cylindrical casing 2 .
  • figure 9 illustrates another applicable solution in which the drainage channels 3,4 , with polygonal cross-section, each extend within a fully spiral extruded compartment 10 with one or more spires, also with polygonal cross-section, build on the internal surface of a cylindrical casing 2 .
  • the invention is structurally simple--the materials, as well as the dimensions of the individual components, may obviously be pertinent according to specific needs.
