Definitions

  • the invention relates to a pellet press for the production of food dice or the like or of wood pellets, in particular it relates to a roller adjustment in such a pellet press.
  • Granular, floury and / or pasty materials with a wide variety of compositions in the food and non-food sectors have been pressed by means of a pellet press for many years.
  • a generic dicing press is disclosed, for example, in EP-A-371519.
  • the material to be pressed passes from a hopper into a conveyor and dosing and from there into a mixer. Both are arranged above the actual pellet press. From the mixer, the material enters a filling box and a mold lid into the mold.
  • an adjusting device for a pair of press rollers is arranged, wherein the press rollers are adjustable by means of a piston-cylinder unit acting on both press rollers or a split spindle arrangement.
  • the roller carrier shaft is secured against rotation by means of a breaking pin.
  • a press roller adjustment is provided, in which on a base of the main shaft two pairs of yoke-provided lever arms are arranged centrally articulated. The other ends of the lever arms are hinged or rotatably attached to eccentrics of the press rollers, wherein the lever pairs are each connected to one, also hinged to the eccentrics and a displaceable on the base element.
  • the object of the invention is to develop a pellet press, in which the function of the press roller adjustment is further improved and which is safer in case of malfunction.
  • the object is solved with the features of the claim.
  • the adjustment of the press rollers takes place from a pivot bearing, which has an outer sleeve with internal spindles. By means of these spindles eccentric levers of the press rollers are operated and the position of the press rollers is determined exactly.
  • the roller adjustment can be operated electrically, hydraulically or pneumatically.
  • Fig. 1 a front view of the press roller adjustment
  • Fig. 2 a detail of Fig. 1 in a perspective view
  • Fig. 3 pivot bearing of the roller adjustment.
  • the embodiment relates to a pellet press, as described for example in WO 2004/022324 of the applicant.
  • a pellet press the material to be compressed is fed via a pre-container to a doser, which in turn passes specific amounts of the material to a mixer.
  • Steam and additives can be added and then the mixed material reaches at most in a Verweiler, where it lingers for a certain time and is thereby sanitized.
  • the material prepared in this way is fed via a channel to a mold lid, from which it passes via the inserter 1 into the interior of a mold and is pressed there by means of press rollers 12 through radial bores of the mold.
  • the pellets enter a dryer / cooler via a channel.
  • press rollers 12 There are two press rollers 12 are provided (only verbally indicated in Figure 2), which can be moved by means of a roller adjustment against the inner surface of the mold and back.
  • the roller adjustment has a rotatable sleeve 11 in a housing (rotary bearing) 3, which is driven with internal rotating, opposing spindles 4, whose respective other ends are hingedly connected to the roller bearing 2.
  • the adjustment of the press rollers 12 takes place from the housing 3, which is arranged at the center of the roller adjustment.
  • About a gear 10 with rotary ring mounted in the housing 3 sleeve 11 is driven with the internal spindles 4.
  • 6 of the press rollers are actuated, whereby the position of the press rollers 12 is determined.
  • the position of the housing 3 is chosen so that it comes to the traction in the entire role adjustment and a closed power flow is generated. Thus occur in the center of the housing 3 no forces, allowing a simple and trouble-free operation of the roller adjustment.
  • each press roller bearing 2 is guided in three plate-shaped levers 5, 6, wherein an inner lever 6 is surrounded by two outer levers 5.
  • the levers 5, 6 are further connected by means of a breaking pin 7.
  • This breaking bolt 7 breaks at a predetermined overload, so that the pressing rollers pivot inwardly in the direction of axis 8 of the main shaft.
  • the mold is held by means of a ring attached to a rotatable mold carrier and a pressure ring.
  • the drive of the mold carrier takes place in the usual way via a main shaft.
  • a fluidic element in the form of an annular air cushion is arranged in the direction of the ring, which by filling with a Fluid allows axial movement of the pressure ring and thus a simple repulsion.

Abstract

L'invention concerne une presse à pellets qui comprime un matériau en farine ou en grains dans des alésages radiaux d'un moule au moyen de rouleaux de compression. Le fonctionnement des rouleaux de compression en particulier ajustables doit être protégé des surcharges et les rouleaux de compression peuvent être déplacés au moyen d'un boîtier (3) monté à rotation et en opposition à des broches (4) opposées qui tournent à l'intérieur du boîtier (3).
