Definitions

  • the invention relates to a press for pressing out liquid-containing substances, in particular agricultural and chemical products, with a drainage element containing a spiral-shaped support element, according to the preamble of claim 1, and a drainage element for use in such a press according to the preamble of claim 17.
  • Such presses are known, for example, from EP 0 145 948 B1, and are used to squeeze the grape juice used as the starting material for the production of wine or fruit juice from grapes or fruits filled into the press.
  • the press described in EP 0 145 948 B1 has a closed container which can be set in rotation about its horizontal longitudinal axis.
  • 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 pipes, which are located in a press chamber, which is defined by a pressurized membrane that is sealed inside the container and divides the container interior into a pressure medium chamber and the press chamber.
  • PCT / EP 01/03962 describes a press which comprises a closed container which can be rotated about its horizontal longitudinal axis, the interior of the container being divided into a pressure medium space and a pressure medium space by at least one press membrane, and one by a cover in the container jacket lockable filling and emptying opening is arranged.
  • the filling and emptying opening is opposite a juice drain located in the press room.
  • In the press room are furthermore arranged across the diameter and essentially perpendicular to the container axis arranged liquid-permeable drainage elements which extend from one end of the container to the other end of the container.
  • the drainage elements are formed by an elastic or 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 in order to feed the juice into a juice collecting nozzle located below, from where it is fed to a collecting container via a collecting line.
  • the problem with the presses described above arises that the drainage elements have to withstand the pressures acting on them from the outside, so that a sufficient drainage of juice is always ensured.
  • the problem arises that the drainage elements provided with metal reinforcement elements to increase the strength have a very high weight, so that they can no longer be used by an operator alone in the interior of the container.
  • the parts that come into contact with the material to be pressed during the pressing in particular the drainage elements, can be easily dismantled for cleaning purposes and can be installed in the container again after the cleaning process. It is particularly important here that the dismantling and cleaning of the drainage elements and the interior of the container can be carried out from the outside, since getting into the container involves a not inconsiderable risk or is even prohibited by safety regulations.
  • Another object of the invention is to provide a drainage element for a press mentioned at the beginning.
  • a press for pressing out liquid-containing substances comprises a closed container, the container interior of which is subdivided into a pressure medium chamber and a press medium chamber by at least one press membrane.
  • a filling and emptying opening which can be closed by a lid, is arranged in the container jacket, into which the pressed material is filled.
  • the filling and emptying opening is assigned a juice drain located in the press medium space, which is connected to the inner region of a drainage element, which extends essentially diametrically through the interior of the container, and which can be removed from the container interior through a removal opening.
  • the drainage element comprises a tube made of juice-permeable material, preferably made of plastic fabric, e.g. Polyester fabric, or metal, one end of which is preferably detachably received on a flange element, preferably a bayonet ring, which can be screwed into an associated receptacle in the container jacket.
  • the other end of the hose is in the preferred embodiment of the invention by a clamp, e.g. two parallel terminal strips, sealed liquid-tight, and in a known manner, e.g. attached to the inner wall of the container on the side of the container opposite the removal opening by means of a securing bolt or a screw connection.
  • a support element is arranged inside the hose, which is designed as a flexible spiral in the manner according to the invention.
  • the spiral preferably consists of a spirally wound stainless steel tube or other food-compatible material and is only one of them in the preferred embodiment of the invention.
  • the end is releasably attached to the flange element, whereas the other free end of the spiral preferably extends diametrically into the interior of the container approximately to the center of the container or beyond.
  • the device according to the invention has the advantage that the drainage element can be produced comparatively easily and inexpensively, and can be removed as a component through the removal opening in a very short time even in the case of very large presses, the removal opening simultaneously serving as a juice drain.
  • the invention further comprises a drainage element for use in a press of the generic type for pressing out liquid-containing substances, in particular agricultural and chemical products, with a closed container, the container interior of which is subdivided into a pressure medium chamber and a press medium chamber by at least one press membrane Drainage element has at least one support element and a hose arranged around it made of flexible tissue permeable to juice, and the support element is formed by an elastic spiral, or contains one or more such elastic spirals.

  • a press 1 according to the invention comprises an elongated cylindrical container 2 which can be rotated about the longitudinal axis 4 of the container via drive devices (not shown in more detail).
  • a press membrane 8 Arranged inside the container interior 6 is a press membrane 8, which is indicated only schematically for reasons of illustration technology and which divides the container interior 6 into a pressure medium chamber 10 and a press medium chamber 12.
  • the pressed material for example grapes
  • the pressed material is filled into the press medium space 12 through one or more filling and emptying openings 14, and after the openings 14 have been closed, the pressure medium space 10 is pressurized by a cover (not shown) between the inner wall of the container 2 and the membrane 6 , for example with compressed air, which has a pressure of z.

  • the spiral 36 can also consist of another elastic hollow or solid material, for example carbon or glass fiber material, and have a different dimension.
