Definitions

  • the invention relates to a roller press with a rotatably mounted outer drum, an eccentrically arranged in the outer drum, rotatably mounted press roll, one of the press nip formed by the press roll and feeding material
  • Feeding device and a product to be discharged from the discharge device Moreover, the invention relates to a method for operating such a roller press.
  • the transfer of a large part of the easily fermentable plant ingredients contained in the plant in the press juice are on the one hand dissolved substances such as glucose and on the other hand undissolved substances such as starch.
  • the aim is to substantially reduce the content of the mineral plant constituents in the pressed material.
  • the transfer of the undissolved, but also the dissolved plant ingredients in the press juice designed as difficult because they are included in the cell structure of the plants of lignocellulose.
  • belt filter presses are suitable for the separation of surface water, but not for the separation of water from the cell structure of the biomass, since the necessary pressures can not be achieved with a belt filter press.
  • Screw presses either with a conical screw in a conical screen jacket or a cylindrical screw with a conical core and / or decreasing pitch in a cylindrical screen jacket, however, have the disadvantage that they lead to relatively large layer thicknesses in the biomass, regardless of the design. With increasing thickness of the layer and increasing compaction of the biomass in the screw namely the flow of water is hindered.
  • the compacted in the screw biomass acts as a filter for undissolved plant ingredients and prevents transfer of these important for the energetic utilization of the press juice substances in the press juice.
  • Roller presses with internal and / or external pressure rollers, with smooth and perforated roller surfaces result in small biomass layer thicknesses in the press nip, whereby a perforation of the rollers also significantly improves the removal of the press juice.
  • very high compression pressures are required for breaking up the cell structure of the biomass, resulting in blockage of the roller perforation.
  • rollers with the structure mentioned at the outset have proven to be cheaper, as they are known, for example, from DE 43 37 890 C2 and DE 32 18 634 A1.
  • these roller presses designed for sludge dewatering or drainage of bark are only conditionally suitable for dehydrating silages, in which a digestion of the cells is also to take place.
  • the object of the invention is therefore to provide a roller press, can be dehydrated with the silage in a single step under cell disruption to a high degree and at the same time a large proportion of plant ingredients can be discharged.
  • the object is achieved with the roller press with the features of claim 1.
  • the subclaims reflect advantageous embodiments of the invention.
  • the basic idea of the invention is to use a conventional roller press with an internal press roll, which has a long pressing zone and a long pressing time which is advantageous for the drainage of silages, whereby the outer drum and the inner press roll are operated at different peripheral speed, whereby shearing forces on the silage be exercised, which lead to a disruption of the cell structure.
  • FIG. 1 shows a cross section through a roller press according to the invention.
  • FIG. 2 shows a horizontal section through the roller press from FIG. 1.
  • the roller press 10 consists of a rotatably mounted outer drum 20 and an eccentrically arranged in this to the axis of the drum 20, also rotatably mounted press roll 30th drum 20th and press roll 30 are arranged at a distance from one another such that a press nip remains, to which the pressed material, in particular silage, is arranged from one side to the press roll 30
  • Feeder 40 is supplied.
  • the feed device 40 which may for example be designed as a screw conveyor, is particularly preferably designed as a vibratory feed trough, i. as a vibrating gutter, from which the crop can fall into the press nip.
  • the vibration dosing is preferably bevelled over the length of the press roll 30, so that the pressed material is distributed in the linear conveying direction in the longitudinal direction of the press roll 30 over the length of the press roll 30.
  • a take-off device 50 is provided, which passes through the press material passed through the press nip Roller press 10 removed. This is preferably a screw
  • Another embodiment of the withdrawal device 50 can be done, for example, as a scratch band.
  • the size ratio of drum 20 to press roller 30 and the distance from the drum 20 and press roller 30 are now set so that the most effective pressing with a long press zone and a relatively long residence time can be achieved in the press zone.
  • the drum is designed and the press nip dimensioned such that at the lowest possible material thickness, a good discharge of the press juice is possible.
  • a suction gate which acts on the openings 24, in particular in the region of the pressing zone with a negative pressure.
  • the openings in the inner wall 22 of the drum are in turn preferably designed such that the openings are arranged as radial or axial slots, which widen conically in the direction of the channels 26.
  • At least one scraper 52 is provided in the area of the extraction device 50, which removes adhering material to be pressed and removes the protruding parts from the fibers pressed into the openings 24 of the drum 20, and removes them
  • Triggering device 50 feeds, wherein the pressed into the openings 24 part of the fibers is discharged in a new circulation in the press zone with the press juice. As a result, a blockage of the openings 24 is avoided.
  • a further scraper 54 may be provided, which strips off adhering to the press roller fibers from the press roll and the trigger device 50 feeds.
  • the pressing force is preferably applied with a (not shown) hydraulic system in the form that the pressing pressure is kept constant and the press nip adapts to the pressed material. If, for example, pressed material with a high dry matter content is supplied to the press nip, the press roll deviates.
  • the pressing force is preferably infinitely adjustable.
  • the invention provides that the drum 20 and the press roller 30, as indicated in Fig. 1 by short and long arrows, with different
  • Circumferential speed are operated, the resulting shear forces are able to break the cell structure of the ensiled plant fibers well, so that at the same time the liberated liquid and phytonutrients can be removed via the arranged in the drum 20 openings 24 and channels 26.
  • the drive of the drum 20 and the press roller 30 can be realized by separate drives, such as. indicated in Fig. 1 by the rollers on which the drum 20 is mounted and which bring the drum to rotate, wherein the axis of the press roll 30 is connected to a stand-alone drive.
  • a single drive can be provided, which drives both drum 20 and press roller 30 with different peripheral speed via corresponding translations.
  • Advantage of the invention is an improved cell disruption and thus a higher yield of erupted with the press juice soluble and insoluble plant ingredients, which allows a better energy recovery of the press juice and the pressed material.

Abstract

Presse à rouleau (10) qui comporte un tambour extérieur (20) monté rotatif, un rouleau comprimeur (30) monté rotatif et situé de manière excentrique dans le tambour extérieur (20), un dispositif d'introduction (40) destiné à introduire de la matière à presser dans un interstice de compression formé entre le tambour (20) et le rouleau comprimeur (30), et un dispositif d'évacuation (50) destiné à évacuer la matière pressée. Ladite presse à rouleau est caractérisée en ce qu'elle comporte au moins un entraînement qui entraîne le tambour (20) et le rouleau comprimeur (30) à des vitesses circonférentielles différentes.
