Definitions

  • the invention relates to a method and a device for cleaning the interior of a press for pressing out liquid-containing substances, in particular grapes, according to the preamble of claims 1 and 13.
  • Presses for squeezing liquid-containing substances are, for example, from the EP 0 145 948 B1 known and are used to squeeze the grape juice used as a raw material for wine production from grapes filled in the press.
  • the in the EP 0 145 948 B1 The press described has a closed container which can be set in rotation about its horizontal longitudinal axis. In the jacket of the container there is a filling and emptying opening which is opposite a juice drain provided on the opposite side of the container and which can be closed by a lid.
  • drainage elements are provided in the form of liquid-permeable tubes, which are located in a press chamber, which is defined by a pressure-membrane-tight press membrane attached to the inside of the container, which divides the container interior into a pressure medium chamber and the press chamber.
  • a press which comprises a closed container which can be rotated about its horizontal longitudinal axis, the container interior being divided into a pressure medium space and a pressure medium space by at least one press membrane, and a filling and emptying opening which can be closed by a lid being arranged in the container shell.
  • the filling and emptying opening is opposite a juice drain located in the press room.
  • Liquid-permeable drainage elements which extend from one end of the container to the other end of the container, are furthermore arranged in the press chamber over the diameter and essentially perpendicular to the container axis.
  • the drainage elements have a flexible support element, around which a juice-permeable fabric tube is arranged. In the juicing position, the drainage elements extend in a substantially vertical direction, around the juice in a below to supply the juice collecting spout, from where it is fed to a collecting container via a collecting line.
  • the general zones of the CIP activities relate in particular to the smooth or concave steel surface of the inner wall of the container, the inner wall of the container covered with the press membrane, the underside of the filling and emptying opening of the press etc.
  • the goals that are pursued when cleaning the above-mentioned machines are the highest possible mechanical and (with the addition of cleaning agents) chemical cleaning effect and disinfection of all surfaces of the above-mentioned devices, less time required for cleaning (often after each pressing, i.e. several times per day (up to 5x), the absence of intervention by the operator, in particular getting into the press container, constant cleaning quality, regardless of the operator, the lowest possible, controllable water consumption and the possibility of automation at the push of a button.
  • the CIP systems should preferably also be retrofittable in existing systems.
  • Another problem with the cleaning system described above is that the material to be pressed is pressed into the nozzle openings and the feed lines during the pressing process due to the high internal pressure, and remains in the feed lines of the nozzles after the pressing process, for example in the form of must residues.
  • Another object of the invention is to provide a method by which the presses described above can be cleaned in a very short time with high efficiency using a small amount of cleaning fluid.
  • the invention has the advantage that an optimal cleaning result can be achieved due to the combined cleaning consisting of water jet spraying, rotary flushing and membrane relaxation. Since the rotation flushing and the membrane expansion can be easily implemented by software in connection with the machine controls (PLC) commonly used in such presses, the method according to the invention can also be easily retrofitted and performed automatically with existing presses after the mechanical according to the invention Components have been installed.
