Definitions

  • the invention relates to a press for pressing liquid-containing substances, in particular agricultural and chemical products, according to the preamble of claim 1.
  • Such presses are for example from the EP 0 145 948 B1 are 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 described press has a closed container which is displaceable about its horizontal longitudinal axis in rotation.
  • a filling and emptying opening In the shell of the container is a filling and emptying opening, which is opposite to a provided on the opposite side of the container juice drain, and which is closed by a lid.
  • the container drainage elements in the form of liquid-permeable pipes are provided, which are located in a pressing space, which is defined by a pressure-tight, fixed inside the container, press membrane, which divides the container interior into a pressure medium space and the pressing space.
  • a press which comprises a closed container which can be set in rotation about its horizontal longitudinal axis, the container interior being subdivided by at least one press membrane into a pressure medium space and a press center space, and a filling and emptying opening closable by a lid being arranged in the container casing.
  • the filling and emptying opening is located opposite a juice outlet located in the press room.
  • liquid-permeable drainage elements are further arranged over the diameter and arranged substantially perpendicular to the container axis, 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 hose is arranged. In the juicing position, the drainage elements extend in a substantially vertical direction to supply the juice to a juice sump below, from where it is fed via a manifold to a sump.
  • the parts coming into contact with the material to be pressed during pressing in particular the drainage elements, can be easily dismantled for cleaning purposes and in turn can be mounted inside the container after the cleaning process. It is of particular importance that the dismantling and cleaning of the drainage elements and the container interior can be done from the outside, since the entry of people in the container associated with a significant risk, or even prohibited by security regulations.
  • the press according to the invention has the advantage that in the case of pressing grapes the juice can be squeezed out of the mash with a very high efficiency. This in turn results in the advantage that the pressures of the pressure medium, which acts on the pressure medium space on the side facing away from the pressed material of the press membrane, can be kept comparatively low, which means that at high extrusion pressures also from the grapes with exiting turbidity not with into the grape juice, resulting in a significant quality gain of the grape juice.
  • the increased efficiency of the press according to the invention means that the pressing of the grapes - compared to known presses of the prior art - can be done within a much shorter time, resulting in the press according to the invention to an increased throughput of pressed material.
  • the flexibility of the juice channels according to the invention in the spatial adhesion by means of a press membrane advantageously means that the press membrane is exposed to significantly lower loads, as is the case in the prior art, since the drainage element is no longer a fixed obstacle to avoid the press membrane must, or at which the press membrane can chafe.
  • Another advantage associated with the flexible embodiment of the drainage elements according to the invention can be seen in the fact that the filling volume of the container with material to be pressed during the filling of the container is e.g. is much better utilized via one or more filling lid, since the flexible, preferably also formed with excess length drainage elements oppose the slipping of the Be Stirllgutes no rigid, centric obstacle. As a result, the pressed material can also reach the container regions not lying near the lid, which leads to an increase in the filling quantity.
  • a further increase in the filling volume results from the fact that the volume of the flexible drainage elements according to the invention is smaller than the filling volume of rigid drainage elements in the case of space squeezing, as used in prior art presses.
  • the container volume available to the pressed material is larger.
  • a rigid drainage element is mainly loaded on bending and pressure, whereas a flexible drainage element is subject exclusively to tensile loads.
  • the stresses on bending and pressure to avoid damage, in these the relevant area moments of inertia must be increased, which is usually associated with an increase in the cross section, which in turn to a larger volume of the relevant rigid drainage element leads.
  • Another advantage that results from the use of the flexible drainage elements according to the invention, is that when loosening the material to be pressed, too in which the container is preferably rotated about its longitudinal axis, the flexibility of each drainage element in each container movement causes any adhering pressed material is shaken off.
  • the surface of the drainage elements, ie the substrate on which the pressed material adheres also changes both its position and its surface shape during rotation of the container, as a result of which the adhering material to be pressed releases itself from the drainage elements without external action , In a rigid drainage element, however, this self-cleaning effect is not given.
  • the press 1 according to the invention shown in Figures 1 and 2 comprises an elongated cylindrical container 2, which is rotatable about a container longitudinal axis 4 via drive means, not shown.
  • the container 2 has a shape deviating from the cylindrical shape, and is rotatable about a longitudinal axis 4 other than the longitudinal axis 4 shown in Figs. 1 and 2, e.g. about an axis perpendicular to the longitudinal axis 4 in the horizontal direction or in the vertical direction axis.
  • a press membrane 8 which is indicated only schematically for illustrative purposes, is arranged, which divides the container interior 6 into a pressure medium chamber 10 and a press center 12.
  • the pressed material such as grapes
  • the pressure medium chamber 10 after closing the openings 14 by unillustrated lid between the inner wall of the container 2 and the membrane 8 is subjected to a pressure medium ,
  • a pressure medium For example, with compressed air, which is a pressure of z. B. may have 1.2 to 2 bar.
  • a preferably nozzle-shaped juice outlet 16 On the side opposite the closable filling and emptying opening 14 of the container 2 is a preferably nozzle-shaped juice outlet 16, which is arranged during the Auspressvorgangs by rotating the container in the corresponding position on the underside of the container 2.
  • a plurality of juice drains 16 are preferably arranged along the longitudinal axis 4 of the container 2, which are interconnected by a connecting line 18, via which the squeezed grape juice is fed to a collecting container, not shown, for further processing.
  • FIGS. 1 and 2 inside the container 2 there are a plurality of flexible or elastic drainage elements 20 which, as shown in FIGS. 1 and 2, are located above the juice drains 16 during the squeezing operation, and which extend substantially perpendicular to the longitudinal axis 4 in a diametrical manner.
  • the drainage elements 20 comprise an elastic or flexible support member 22, and a juice-permeable hose 24 disposed about the flexible support member 22.
  • the hose 24 is made of a flexible or elastic fabric, for example a multi-ply nylon fabric, which has a Preferably mesh size of less than one millimeter has, and which is suitable to guide the grape juice through the tissue into the region of the support elements 22, on the other hand, however, keep the particles contained in the pressed material from the area of the support elements 22.
  • the hose 24 will be referred to below as a fabric hose 24.
  • the juice-permeable fabric hose 24 is preferably provided with a zipper 26 extending in the longitudinal direction of the drainage element 20 such that the fabric hose 24 can be wrapped around the support elements 22 with the zipper open and thereafter Close the zipper 26, the support elements 22 completely surrounds.
  • the juice-permeable fabric tube 24 is provided at its ends with a circumferential bead 28 which serves to secure the ends of the fabric tube 24 by means of associated holding devices on the inside of the container interior, which will be described in more detail below.
  • the drainage elements 20 preferably have a length that is slightly larger than the diameter of the container interior 6. This results in the advantage that the drainage elements 20 and in particular the support elements 22 contained therein during the pressing process due to their flexibility to the different pressure conditions within the pressed material, that is the mash, can adapt.
  • the attachment of the drainage elements 20 takes place here in accordance with the invention by means of holding devices in such a way that due to their construction even in very large containers 2 extremely light drainage elements 20, which are arranged from the interconnected fabric tubes 24 and within the fabric tubes 24 and assembled supporting elements 22 can be removed as a component from the interior 6 of the container 2.
  • the holding devices on the side of the drainage elements 20 are formed by clamping pieces 30, 32, on which the support elements 22 designed as support tubes are fastened by means of per se known compression fittings 34 are attached.
  • the juice outlet side clamping piece 30 is in this case preferably circular and cooperates with an associated clamping flange 36, with which it is screwed after insertion of the bead 28 of the fabric tube 24 between the clamping piece 30 and an associated clamping flange 36 at the juice drain end to form a liquid-tight connection.
  • juice outlet openings 38 are formed, which divert the pressed through the tissue of the fabric tube 24 grape juice to the juice outlet 16 out.
  • the clamping flange 36 cooperates at the juice outlet end of the drainage member 20 with a retaining flange 40, which is preferably secured to the shell surface of the container 2 by welding, but may be otherwise secured.
  • the insertion and removal of the drainage elements 20 is preferably carried out through removal openings 15, which are formed according to the illustration of Fig. 3 in the region of the nozzle-like juice drains 16, and which are closed by schematically illustrated cover 17.
  • the retaining flanges 40 and the associated clamping flanges 36 form a bayonet closure, in such a way that the circular clamping flanges 36 can be engaged by twisting them with their associated retaining flanges 40, e.g. to attach the externally as a part through the opening 17 in the container 2 introduced drainage element 20 on the container 2.
  • the clamping piece 32 is preferably oval on the side of the container 2 opposite the juice outlet 16, and has a shorter axis 46 and a longer axis 48.
  • the drainage element 20 is preferably arranged and aligned in the region of the end of the container 2 opposite the juice outlet 16 in such a way that the shorter axis 46 extends substantially parallel to the longitudinal axis 4 of the container 2.
