Abstract

In the pressing of cocoa butter by a hydraulic press, optimum pressure, pressing piston speed are selected to be as close as possible to empirically established curves, proceeding start with parameters of one of these curves. Water and fat content for the material used are stored in a computer. After pressing for 2-4 minutes. Measurements take place of extruder head pressure, amt. of extruded cocoa butter, and the temp. of the material. These results are compared by the computer with stored correlation functions, and the nearest such set of functions is established and used for subsequent pressing controls. ADVANTAGE - Pressing time is reduced to optimum minimum without calling on operator's experience.

Description

Die Erfindung wird angewendet in Kakaopreßanlagen und betrifft ein Verfahren zum Steuern des Abpressens von Kakaobutter, wobei der Preßvorgang in Abhängigkeit vom Preßdruck und der Geschwin­ digkeit des Preßkolbens erfolgt und nach vorhandenen empirisch ermittelten Kurven gesteuert wird.The invention is applied in cocoa press plants and relates a method for controlling the pressing of cocoa butter, wherein the pressing process depending on the pressing pressure and the speed The plunger is made empirically and according to existing ones determined curves is controlled.

Bei den gegenwärtig bekannten Kakaopreßanlagen erfolgt eine elektromechanische Steuerung des Abpreßvorganges der Kakao­ butter. In einem aktuellen Prospekt des VEB Maschinenfabrik Hei­ denau ist eine solche Steuerung beschrieben.In the currently known cocoa press systems, a Electromechanical control of the pressing process of the cocoa butter. In a current brochure from VEB Maschinenfabrik Hei Such a control is described in detail.

Die Zeitdauer des Preßvorganges bzw. der Restfettgehalt im Kakao­ preßkuchen kann entweder durch das einstellbare Gesamtbutterge­ wicht, durch Messung des Gesamthubes oder durch manuelle Be­ dienung begrenzt werden. Kriterium dabei ist der über Sensoren aufgenommene Preßdruck im Preßtopf bzw. der Preßdruck und die Geschwindigkeit des Preßkolbens. Weiterhin ist es möglich, durch Auswahl eines der vorgegebenen 7 Programme eine Anpassung an jeweils vorliegende Kakaomasse zu erzielen. Weiterhin stehen noch 4 Programme mit unterschiedlichen Geschwindigkeitstufen zur Aus­ wahl, die im Bedarfsfall ein langsames Anpressen gestatten.The duration of the pressing process or the residual fat content in the cocoa Press cake can either by the adjustable total butter important, by measuring the total stroke or by manual loading service can be limited. The criterion here is that of sensors recorded pressure in the press pot or the pressure and the Speed of the plunger. It is also possible to go through Select one of the 7 preset programs to adapt to achieve each cocoa mass present. Still standing 4 programs with different speed levels to stop choice that allow a slow pressing if necessary.

Nachteilig hierbei ist, daß die Preßzeit länger als unbedingt erforderlich gewählt und damit kein optimaler Preßvorgang erzielt wird.The disadvantage here is that the pressing time is longer than absolutely necessary selected required and thus no optimal pressing process achieved becomes.

Der Grund dafür ist, daß die Steuerung des Preßvorganges nach Erfahrungswerten des Bedieners erfolgt. Insbesondere bei Massen, wo derartige Erfahrungswerte noch nicht vorliegen, macht sich dieser Nachteil deutlich bemerkbar.The reason for this is that the control of the pressing process after Experience of the operator is done. Especially with masses, where such empirical values are not yet available this disadvantage is clearly noticeable.

Der Erfindung liegt die Aufgabe zugrunde, den Preßvorgang auf der Grundlage massetypischer Parameter zu steuern.The invention has for its object the pressing process on the To control the basis of mass-typical parameters.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die empi­ risch ermittelte, günstige Preßgeschwindigkeit eingestellt wird, die Parameter Wassergehalt und Fettgehalt der Masse in einen Meß­ wertspeicher eingegeben werden, nach 2-4 Minuten der Druck im Preßtopf, die abgepreßte Kakaobuttermenge und die Temperatur der Masse ermittelt wird, ein Vergleich mit gespeicherten massespezi­ fischen Korrelationsfunktionen erfolgt, die nächstliegendste Korrelationsfunktion ermittelt wird und der Preßvorgang weiter nach der ausgewählten Korrelationsfunktion gesteuert wird.The object is achieved in that the empi risch determined, favorable pressing speed is set, the parameters water content and fat content of the mass in one measurement value memory can be entered, after 2-4 minutes the pressure in Press pot, the amount of cocoa butter squeezed and the temperature of the Mass is determined, a comparison with stored mass speci fishing correlation functions takes place, the closest Correlation function is determined and the pressing process continues is controlled according to the selected correlation function.

Die erfindungsgemäße Lösung hat den Vorteil, daß ein optimaler Preßvorgang erzielt wird, d. h., daß eine erhebliche Verkürzung der Preßzeit bei maximaler Schonung der Kakaomasse erfolgt.The solution according to the invention has the advantage that an optimal one Pressing process is achieved, d. that is, a significant shortening the pressing time takes place with maximum protection of the cocoa mass.

Das Verfahren soll nun an Hand eines Ausführungsbeispieles näher erläutert werden.The method will now be described in more detail using an exemplary embodiment are explained.

Vor dem Preßvorgang erfolgt einmalig die Eingabe des Fett- und Wassergehaltes der zu verarbeitenden Masse.Before the pressing process, the fat and are entered once Water content of the mass to be processed.

Der Preßvorgang erfolgt mit einer empirisch ermittelten Preßge­ schwindigkeit, die bei den üblichen Kakaopreßanlagen 96-104 mm/min beträgt. Nach 2-4 Minuten, vorzugsweise nach 3 Minuten, werden durch Sensoren der Druck im Preßtopf, die Temperatur und die abgepreßte Kakaobuttermenge erfaßt. Die Ausgangssignale der Sensoren und die Eingabewerte werden einem Rechner zur Auswertung zugeführt, der diese in Form einer Matrix in einen Speicher ab­ legt. The pressing process is carried out with an empirically determined press speed, which with the usual cocoa presses 96-104 mm / min. After 2-4 minutes, preferably after 3 minutes, are the pressure in the press pot, the temperature and the amount of cocoa butter squeezed. The output signals of the Sensors and the input values are a computer for evaluation supplied, which in the form of a matrix in a memory sets.  

In diesem Speicher sind eine Vielzahl empirisch ermittelter, massespezifischer Meßparameter abgelegt, aus denen wiederum massespezifische Korrelationsfunktionen gebildet werden, die den optimalen Abpreßgrad für die betreffende Masse charakterisieren. Diese werden aus den Parametern Preßdruck als Funktion der Zeit, der Massetemperatur, dem Wasser- und Fettgehalt der Masse, der Dichte der Masse sowie aus dem Preßkammervolumen und der Butter­ menge als Funktion der Zeit gebildet.A large number of empirically determined, mass-specific measurement parameters stored, from which in turn mass-specific correlation functions are formed that the Characterize the optimal degree of pressing for the mass in question. These are made up of the parameters of baling pressure as a function of time, the mass temperature, the water and fat content of the mass, the Density of the mass as well as from the bale chamber volume and the butter quantity formed as a function of time.

Die Korrelationsfunktionen werden mit den in der Matrix abgeleg­ ten Meßwerten für den Druck, der Temperatur und der abgepreßten Kakaobutttermenge verglichen. Im Ergebnis wird eine optimale Korrelationsfunktion ausgewählt, die als Abpreßfunktion ausge­ geben wird.The correlation functions are stored with those in the matrix th measured values for the pressure, the temperature and the pressed Amount of cocoa butter compared. The result is an optimal one Correlation function selected, the out as a squeeze function will give.

Nach dieser Funktion wird der weitere Preßvorgang gesteuert, d. h., es werden Signale dem Hydrauliksystem der Kakaopresse zuge­ führt.After this function, the further pressing process is controlled, d. that is, signals are sent to the hydraulic system of the cocoa press leads.
