Bisher erfolgte die Trennung eines Bruchgutes mittels elektrostatischer Kräfte, wobei das Bruchgut in fraktionierter Form in einer Aufladungszone zwischen zwei unterschiedlich geladenen Elektroden elektrisch aufgeladen und gleichzeitig einer Vibrationsbewegung unterworfen wird, deren Stärke zur Einstellung der Verweilzeit des Bruchgutes in der Aufladezone und damit der Aufladezeit für die Bruchgutfraktionen gesteuert wird. Hierzu werden die CH 381 060 A und EP 0 980 713 genannt. Zusätzlich wird auf die GB-A-1 069 270 verwiesen, die sich aber mit einer Vorrichtung zur Behandlung von Samen befaßt und in diesem Zusammenhang eine elektrostatische Trennung der Samen im Hinblick auf ihre Größe vorsieht, so dass das der Erfindung zu Grunde liegende Problem aus der Druckschrift keine direkte Beantwortung findet. Das Verfahren gemäß dem Dokument CH 381060 und die Vorrichtung gemäß dem Dokument GB 1069270 sind als nächstliegender Stand der Technik anzusehen. Die Aufgabe der Erfindung beste nun darin, das Verfahren der genanten Art sowie die zu seiner Durchführung dienende Vorrichtung so zu verbessern, dass der Wirkungsgrad der Trennung des Bruchgutes weiter erhöht wird. So far, the separation of a broken material by means of electrostatic forces, which Fractured material in a fractional form in a loading zone between two differently charged Electrodes are charged electrically and at the same time subjected to a vibration movement is, their strength to adjust the dwell time of the broken material in the loading zone and thus the charging time for the broken fragments is controlled. For this, the CH 381 060 A and EP 0 980 713. In addition, reference is made to GB-A-1 069 270, which is but concerned with a device for the treatment of seeds and in this context provides for electrostatic separation of the seeds in terms of their size, so that the problem underlying the invention is not a direct one from the publication Answer finds. The method according to document CH 381060 and the device according to document GB 1069270 are to be regarded as the closest prior art. The object of the invention best now is the method of the type mentioned and the its implementation device to improve so that the efficiency of the separation of the broken material is further increased.
Diese Aufgabe wird, was das Verfahren anbelangt, gemäß dem Kennzeichen des
Hauptanspruchs, und was die Vorrichtung anbelangt, gemäß dem Kennzeichen des
Anspruchs 4 gelöst.As far as the procedure is concerned, this task is carried out in accordance with the characteristics of the
Main claim, and as far as the device is concerned, according to the characteristic of
Vorteilhafte Ausgestaltungen des Verfahrens sowie der Vorrichtung der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the method and the device of the invention are shown in marked the subclaims.
Die Erfindung wird nachfolgend an Hand des in der Zeichnung schematisch dargestellten Ausführungsbeispiels einer Trennvorrichtung näher erläutert.The invention is illustrated below with reference to that shown schematically in the drawing Embodiment of a separation device explained in more detail.
Zur Durchführung des Verfahrens zur Trennung eines Bruchgutes, bestehend aus in einem
Brecher gebrochenen Körnern oder Nüssen oder Mandeln oder Bohnen und ihren Schalen,
insbesondere aber zur Trennung von Kakaokernbruch, den sogenannten Nibs, von den
Kakaobohnenschalen, wird das Bruchgut 5 in fraktionierter Form roh oder getrocknet oder
getrocknet und dampfbehandelt oder geröstet oder geröstet und dampfbehandelt in einen
Aufgabetrichter 4 eingegeben, dessen Ausgangsende in eine Vibrations- oder Rüttelrinne 6
mündet, welche mit unterschiedlich geladenen, ein homogenes elektrisches Feld
erzeugenden Elektroden 7, 8 versehen ist, zwischen denen das zu trennende Bruchgut
hindurchgefördert wird, um dabei elektrostatisch aufgeladen zu werden. Aufgabetrichter 4
und Vibrationsrinne 6 bilden zusammen mit den Elektroden 7, 8 die Aufladungszone 1 der
Trennvorrichtung.To carry out the process for separating a broken material, consisting of in one
Crusher broken grains or nuts or almonds or beans and their shells,
but especially for the separation of cocoa nibs from the
Cocoa bean husks, the
Die Vibrationsrinne 6 ist mit einem nicht dargestellten Vibrationsantrieb ausgestattet, der
so eingestellt werden kann, dass eine gewünschte Bruchgutfördergeschwindigkeit erreicht
wird, wobei durch die Tatsache, dass der Aufgabetrichter 4 höhenverstellbar ist, die
Fördermenge der Vibrationsrinne zusätzlich beeinflusst werden kann. Die Vibrationsrinne
ist nach außen vollständig elektrisch isoliert. Ihre Wandung besteht aus Kunststoffmaterial,
in das die Elektroden 7, 8 eingebettet sind und ist mit Metall ausgekleidet. Die
Innenwandung der Vibrationsrinne ist außerdem mit Konturen in Form von höckerartigen
Gebilden versehen, die der Durchmischung der über sie hinweglaufenden Bruchgutteilchen
5 dienen sowie der Optimierung der auf die Teilchen mit Hilfe der Elektroden zu
übertragenden elektrischen Ladung. Um diese Übertragung zu optimieren, wird die
Ausbildung einer Einkornschicht auf dem Vibrationsrinnenboden angestrebt. Die
bodenseitige Elektrode 7 liegt an einer Gleichspannung (U+) von etwa 20-40 kV und
stellt die Anode dar, während die direkt darüber befindliche zweite Metallelektrode 8 die
geerdete Kathode ist und den Ladungsübergang auf die Bruchgutteilchen 5 unterstützt. The
Bei ihrer Bewegung zwischen den Elektroden 7 und 8 hindurch werden die
Bruchgutteilchen, nämlich die Nibs und Schalen, unterschiedlich stark aufgeladen. Die
Ladung sitzt im wesentlichen auf der Oberfläche dieser Teilchen, die übertragene
Ladungsmenge ist somit proportional der Größe der Teilchenoberfläche. Die
Geschwindigkeit, mit der die Aufladung erfolgt, hängt von der elektrischen Leitfähigkeit
des Materials ab, die bei den Schalen und Nibs etwa gleich groß ist.When moving between the
Somit ist die Aufladungszone 1 entsprechend der Größe der auf die Teilchen zu übertragenden Ladung auszulegen, da die Größe der elektrischen Aufladung der Teilchen für die nachfolgende Trennung in der sich an die Aufladungszone 1 anschließenden Ablenkzone 2 entscheidend ist.Thus, the charging zone 1 corresponds to the size of the particles to transfer charge because of the size of the electrical charge of the particles for the subsequent separation in the one following the charging zone 1 Deflection zone 2 is crucial.
Die beiden Elektroden 7 und 8 der Ablenkzone 2 sind mit einer isolierenden Schicht
überzogen, da anderenfalls bei Kontakt der geladenen Bruchgutteilchen mit den Elektroden
Umladungvorgänge stattfinden und die Teilchen zwischen den Elektroden hin- und
herspringen würden.The two
Das Bruchgut wird, wie aus der Zeichnung ersichtlich, nach seiner Aufladung dadurch getrennt, dass die Kakaobohnenschalen als leichtere Bruchgutteilchen von dem Kakaokernbruch (Nibs) als schwerere Kernbruchteilchen durch Absaugen ersterer und Abscheidung der leichteren Teilchen in einem Windsichter getrennt werden.As can be seen from the drawing, the broken material becomes thereby after it has been loaded separated that the cocoa bean shells as lighter fragments from the Cocoa Core Fracture (Nibs) as heavier core fragments by suction of the former and Separation of the lighter particles can be separated in an air classifier.
Über der Elektrode 8 befindet sich eine Absaugvorrichtung 25, bestehend aus einer Haube
24 und einem sich an ihr anschließenden Absaugrohr 26, das mit einem als Zyklon 20
ausgebildeten Windsichter 27 in Verbindung steht, der seinerseits über ein Abluftrohr 21
mit einem Sauggebläse 28 verbunden ist. Das Abluftrohr 21 mündet in den Zyklon 20, auf
dessen konischer Innenwandung sich die Kakaobohnenschalen 16 sammeln, um in einen
an unteren Ende des Zyklons angeordneten Aufnahmebehälter 24a zu fallen. Die aus dem
Abluftrohr 21 mit Hilfe des von einem Motor 22 angetriebenen Sauggebläse 28
abgesaugte Luft gelangt als Abluft 23 ins Freie.Above the
Dadurch, dass sich die leichteren Bruchgutbestandteile, also die Kakaobohnenschalen 16,
bei der elektrischen Aufladung des Bruchgutes zwischen den Elektroden 7 und 8 von den
schwereren Kernbruchteilchen (Nibs) abheben, wie gezeigt, gelangen sie an die Elektrode
8, werden dort entladen und treten durch deren Lochplatte hindurch in die Haube 24 der
Absaugeinrichtung 25 und damit aus dem Förderbereich der Vibrationsrinne 6, so dass
diese an ihrem Ende 29 nur die Kakaokernbruchteilchen 15 abwirft, die in ein
Fördersystem 13 gelangen, das sie abtransportiert.Because the lighter fragments, i.e. the cocoa bean husks 16,
in the electrical charging of the broken material between the
Für den Aufladungs- und Entladungsvorgang der Bruchgutteilchen und damit den Trennvorgang ist auch die Feuchtigkeit des Bruchgutes eine wesentliche Einflussgröße, da sich die Leitfähigkeit des Materials mit dem Feuchtigkeitsgehalt stark ändert. Es können daher hier nicht dargestellte Einrichtungen zur Bruchgutbefeuchtung vorgesehen werden sowie zur Klimatisierung der gesamten Anlage, die zu diesem Zweck von einem ebenfalls nicht dargestellten Gehäuse umschlossen werden kann.For the loading and unloading process of the fragments and thus the Separation process is also the moisture of the broken material an important influencing variable, because the conductivity of the material changes significantly with the moisture content. It can therefore, devices for moistening the fragments not shown here are provided as well as for the air conditioning of the entire system, which is also done by one for this purpose housing, not shown, can be enclosed.
Darüber hinaus ist eine mehrstufige Ausführung der dargestellten Trennvorrichtung möglich, falls dies der gewünschte Wirkungsgrad der Anlage erfordern sollte.In addition, a multi-stage version of the separation device shown possible if this is required by the desired system efficiency.
Das erfindungsgemäße Verfahren zeigt, dass die Trennung von Nibs und Schalen mit Hilfe
einer elektrostatischen Trennvorrichtung möglich ist, wobei die auftretenden Kräfte im
elektrischen Feld von ausreichender Größe und die Unterschiede von Nibs und Schalen
ausreichend sind, um diese beiden Bruchgutbestandteile voneinander zu trennen. Die
notwendigen Spannungen liegen im Bereich von 40 kV bis 50 kV. Durch geeignete
Fraktionierung des in den Aufgabetrichter 4 gelangenden Bruchgutes 5 können besonders
große Teilchen vorher abgetrennt werden, wenn die Vorrichtung für sie keine optimale
Trennleistung bietet. Im übrigen lassen sich die Trennergebnisse durch eine Variation des
Elektrodenabstandes, der angelegten Spannung, der Polarität der Spannung sowie der
Fördermenge und des Feuchtigkeitsgrades der Nibs und Schalen optimieren.The inventive method shows that the separation of nibs and shells with the help
an electrostatic separation device is possible, the forces occurring in
electric field of sufficient size and the differences of nibs and shells
are sufficient to separate these two fragments. The
necessary voltages are in the range of 40 kV to 50 kV. By suitable
