Definitions

  • the invention relates to a husk separator, in particular for separating the husks from cereal grains, preferably from peeled Sraunreis.
  • Grain especially rice
  • Peeling machines with rubber rollers are known for this purpose. These are followed by shell separators in order to be able to cleanly separate the peeled brown rice from the removed shell parts in the air flow.
  • shell separators have three separation zones and in addition to the brown rice, several mixed fractions are u. a. educated.
  • a similar cleaning machine for wheat is described in RU-PS 2133149.
  • the wheat is first separated from the round and long-grain trimmings and then light products and dust are separated.
  • the flow of wheat then arrives in an additional pneumatic separation channel, from where gravel and broken grains are removed. The air is cleaned and reused.
  • the invention is based on the object of creating a shell separator which enables efficient separation of the husks from cereals, in particular from husked brown rice. This with much higher readout performance and at least constant readout quality.
  • the solution of the task is carried out with the features of the claim.
  • at least two infeeds are arranged one above the other parallel to the product distribution for the brown rice husk mixture and a circulating air stream is directed onto two readout zones.
  • the air distribution can be adjusted by a flap ⁇ to.
  • the invention is based on the knowledge that it is not only the product feed that has to be uniform over the width of the readout zone. Rather, in the case of shell mixtures, a certain amount over the width of the feed length must not be exceeded for an accurate readout, the readout error increasing only slowly up to a limit power, but increasing very drastically with a further increase in output.
  • the brown rice streams are combined again to form a product stream.
  • the readout power can be at least doubled for the same reason ⁇ area and only an insignificant increase of the height and at least the same quality.
  • a steeper course of the viewing channel also makes it easier for gravel to be removed from the shells.
  • the feed length is doubled with almost the same machine width.
  • the invention is described in more detail in an exemplary embodiment with reference to a drawing.
  • the drawing shows in two partially sectioned views ( Figures 1 and 2) a double-shell separator and its assignment to a peeling machine.
  • the peeling machine preferably a rubber roller peeler 1, as disclosed for example in USP 4194445 or DE-A-10043998, consists of a housing with an inlet 13 for unhulled rice, a vibro feed 11 and a pair of peeling rollers 1a, 1b, thereof first peeling roller fixedly mounted in the housing and whose second peeling roller is movable by arrangement on a pivotably mounted on the housing Trä ⁇ ger relative to the first peel roller and is pressed by a predetermined external force against the ⁇ not shown).
  • a rubber roller peeler 1 consists of a housing with an inlet 13 for unhulled rice, a vibro feed 11 and a pair of peeling rollers 1a, 1b, thereof first peeling roller fixedly mounted in the housing and whose second peeling roller is movable by arrangement on a pivotably mounted on the housing Trä ⁇ ger relative to the first peel roller and is pressed by a predetermined external force against the ⁇ not shown).
  • the driving force comes from a motorized drive 12 by means of an endless belt 12a, which is driven by a driven drive pulley 12b, 12c, which is mounted on the shafts of the peeling rollers 1a, 1b, and at least at least one driving drive pulley 12d and at least one tensioning or deflecting pulley 1 e are guided to the peeling rollers.
  • the mixture of husked brown rice B and removed shells S enters the double-shell separator 2 located below the rubber roller peeler 1.
  • the good mixture is uniform by means of two distribution screws 22, 22 * Distributed over the entire width of a viewing channel 24 and flowed through by the air flow 31
  • the air flow is adjusted so that the brewing ice B falls down against the screw 25, 25 'and is discharged to the side (outlet 35, 35').
  • the two partial flows are then combined again to form a brown rice flow (not shown).
  • the shells are brought out via the shell screw 27.
  • the air is circulated.
  • the recirculated air flow 31 (circulating air) is blown through sieve plates 33 by means of a distribution flap 32 and directed to both readout zones 34, 34 '
  • a bypass flap 28 arranged at the top below the lower guide plate 23 prevents the suction behavior of the fan 30 from being impaired by the air flow. Further baffles are arranged in such a way that parts of the slag are easier to separate from the shells above the bottom of the viewing channel 24 (not shown).
  • the fan 30 has a single drive and one or more drives are provided for the screws 22, 22 ⁇ 25, 25 ⁇ 27, which enable speed adjustment and better distribution of the drive power.
  • the rubber roller peeler 1 is set laterally offset above the screws and the outlet area of the rubber roller peeler 1 (above the dining area 21 of the shell separator 2) is divided into two approximately equal-sized channels 37, 38 with a separating plate 36.
  • the width and the height of the shell separator 2 are only increased by a few centimeters in comparison to a conventional shell separator, due to the second feed, respectively. the second readout zone.

Abstract

La présente invention concerne un séparateur d'enveloppe (2) conçu pour séparer les parties d'enveloppe de céréales décortiquées. Un tel séparateur d'enveloppe est par exemple installé après un système de décorticage à rouleau en caoutchouc. Ledit séparateur d'enveloppe présente deux zones de sélection (34, 34') qui sont situées l'une au-dessus de l'autre.
