  • a press with these features is known (EP 0 421 503 A1), the central juice collection channel being provided with a tubular extension towards the lower container bottom, ie in the area of its juice outlet, and being inserted with this extension into a tube of the juice outlet.
  • the juice collecting channel Towards the top of the container bottom, the juice collecting channel has a conical, narrowing part, onto which a tubular part is placed, which in turn is inserted into a coupling.
  • This coupling is arranged on a lid that is screwed onto the container.
  • the liquid-containing substances which are in particular grape mash, are filled in via the lid arranged on the upper container bottom.
  • a pressure medium supply ring is arranged around the container jacket and is acted upon by the pressure medium via one of the stub axles. Furthermore, the essentially tubular press membrane is attached to the upper and lower container bottoms with the aid of flange rings.
  • This known press has the disadvantage that the installation and removal of the central juice collecting duct for cleaning purposes is associated with some effort and cannot be carried out easily by inexperienced persons.
  • the cleaning of such presses must be carried out at regular, short intervals, and disassembly and assembly must be possible quickly and easily in order to avoid downtimes.
  • the invention has for its object to design a press of the type mentioned so that easy cleaning of the press and in particular the central juice collection channel is possible with quick and easy disassembly and assembly.
  • a flange is fastened to the narrowing lower section of the juice channel, which flange is fastened to a further flange running around the juice drain on the lower tank bottom, that on the cylindrical section of the tank bottom ending below the upper tank bottom Juice channel a funnel-shaped part is attached, the edge of which is centered on the container opening.
  • An advantageous embodiment consists in that the cylindrical section of the juice channel can be closed near its upper edge by means of a removable cover.
  • a juice channel centering tube can be attached to the further flange.
  • a feed line for the liquid-containing substances is connected to the press chamber at the bottom of the container.
  • bores are provided in the cover flange for connecting a fermentation valve or a ventilation valve or a safety valve.
  • sieve channels are provided as pressure medium feeds on the inner wall of the container, which run along the diameter of the container in the region of the axis of rotation and parallel to the longitudinal axis of the container.
  • a further advantageous embodiment consists in that the membrane is fastened to the upper and lower tank bottom by means of flange rings, the flange ring being fastened to the lid flange on the upper tank bottom and bevelled at the edge.
  • a rupture disk be installed as a safety device in a branch to the feed line for the liquid-containing substances.
  • the container lid which is provided with a flange at its edge, has a guide slot with a bore, with which a fastening element interacts.
  • the fastening element consists of a fastening screw with a cylindrical shaft and a threaded section that can be screwed into the cover flange.
  • the press shown in the drawings has an elongated cylindrical container 1 which is rotatably supported on stub axles 12, 13 about a horizontal axis of rotation.
  • the longitudinal axis 2 of the container 1 runs here perpendicular to the axis of rotation 3, the plane running through the axis of rotation 3 dividing the container 1 into two halves of equal size.
  • the container 1 is closed on both ends by means of a curved container bottom 4 and 5.
  • a juice collection channel 8 Arranged in the interior of the container 1 is a juice collection channel 8, which extends over the entire height or length of the container 1, the axis of which coincides with the longitudinal axis 2.
  • a container-shaped press membrane 9 which is adapted to the container shape and is made of flexible material, is arranged, which is fastened in the region of the upper container base 4 and the lower container base 5 in a pressure-tight manner.
  • a pressure medium chamber 10 and a press chamber 11 are formed in the interior of the container 1.
  • a container cover 6 is provided on the upper container base 4 and can be screwed to a cover flange 24 arranged at the upper container opening 35.
  • a juice drain 7 connected to the juice collection channel 8.
  • the juice collection channel 8 (FIG. 5) essentially consists of a cylindrical section or tube 17 made of perforated sheet metal or plastic and continues at the bottom in a narrowing or tapering section 14 to which a flange 15 is attached. Screws 36 are also arranged on this flange 15. Towards the top of the cover, the cylindrical section 17 ends below the cover 6 and forms a certain distance from it, a funnel-shaped part 18 being attached to the end, the laterally projecting edge 19 of which is held between the cover 6 and the cover flange 24 and thus centered (Fig. 6)
  • the upper opening of the juice collecting channel 8 is provided with a removable cover 20, to which spring clips 38 are attached, which are inserted over cross pins 37.
  • Handles 39 on the removable cover serve to handle the juice collection channel 20.
  • Corresponding handles 40 are provided on the cover 6. Due to the shape of the juice collecting channel 8, it can be cleaned very well with a high-pressure cleaner or a brush from above, ie from the cover 6.
  • quick and easy disassembly or assembly is possible, only the fastening to the screws 36 or the flanges 15, 16 having to be released and then after opening the cover 6 the entire channel can be removed from the container 1 ( 7)
  • a further flange 16, to which a sleeve 41 is fastened, is arranged on the lower container bottom 5 for fastening the flange 15.
  • the juice drain 7 is located on this sleeve 41.
  • This sleeve 41 is provided with an internal thread 21, into which a juice channel centering tube 22 can be screwed, with the effect that the juice collecting channel 8 can be used in a guided manner during assembly.
  • the pressure membrane 9 is clamped on the cover flange 24 with the aid of a flange ring 31, this flange ring 31 having a sloping bevel 43 on its outer edge and no residue of pomace can be deposited on the ring by this arrangement. This also makes cleaning easier.
  • the edge of the press membrane 9 is clamped in a sealed manner with the aid of a flange ring 32 against a flange ring 44 on the container bottom 5 (FIG. 7). If necessary, the fastening or the configuration of the flange rings can be carried out as for the upper container bottom 4.
  • a lid attachment can be provided as shown in FIGS. 9 and 10.
  • the flange 50 welded to the edge of the curved cover 6 has a guide slot 52 with the radius of the cover hole circle and ends in an enlarged bore 53.
  • a fastening screw 49 with a cylindrical shaft and a threaded section 51, which is screwed into the cover flange 24, serves to connect the flange 50 and the cover flange 24.
  • the width of the guide slot 52 corresponds approximately to the diameter of the threaded section 51 and the diameter of the bore 53 corresponds approximately to the diameter of the cylindrical shaft of the fastening screw 49.
  • a handle 55 is used to turn the fastening screw 49, which is pivotable on the cylindrical shaft of the fastening screw 49 is arranged.
  • the container lid 6 can be rotated according to the angle of rotation 54, the bore 53 being in the region of the fastening screw 49 in the open position, so that the lid 6 can be lifted upwards.
  • the cover is turned in the opposite direction until the threaded section 51 comes to rest at the end of the slot 52 and the fastening screw 49 is then tightened using the handle 55.
  • the fruit mash is supplied via a nozzle 42 (FIGS. 1 and 7) arranged on the lower container bottom within the flange rings 32, 44, to which a feed line 23 is connected.
  • This feed line 23 is led to the stub shaft 12 and from there the mash is filled into the container under pressure. Because the filling takes place from below, that is to say in ascending order, the mash is fed in particularly gently and the amount of slurry is reduced. In addition, a particularly favorable pre-juicing can be achieved, since the juice can reach the juice drain via the juice channel 8 in the shortest possible way.
  • the air is supplied via the stub shaft 13, 1 sieve channels 29, 30 being arranged in the interior of the container.
  • a sieve channel 29 runs in a ring along the diameter of the container 1 in accordance with the plane defined by the axis of rotation 3 and the further sieve channels 30 are arranged perpendicularly thereto.
  • These sieve channels 30 run parallel to the longitudinal axis 2, lie opposite one another, are offset by 90 ° with respect to the stub axles 12, 13 and are connected to the sieve channel 29.
  • the formation of these sieve channels results from FIG. 3.
  • the sieve channels 29, 30, which are trapezoidal in cross section, are screwed down with the aid of hold-down devices 46, which are arranged at a distance and on blocks 45 fastened to the inner wall of the container.
  • This configuration of the sieve channels 29, 30 makes it easier to clean these channels if, for example, the membrane is damaged or bursts. In addition, this results in better air distribution and the pressure membrane 9 is evenly pressurized.
  • FIG. 8 shows a safety device in which a rupture disk is connected to a branch 33 of the feed line 23 for the mash, to which a diaphragm seal 47 is also assigned.
  • a measuring device can be placed on this diaphragm seal 47.
  • This arrangement is preceded by a shut-off device 48.
  • the advantage of this device is that it becomes effective when excess pressure builds up in the press. This danger can be eliminated by bursting the rupture disk 34.
