Description

Verfahren zur Steuerung der Entsaftung organischer Produkte Process for controlling the juicing of organic products
Die Erfindung betrifft ein Verfahren zur Steuerung der Entsaftung organischer Produkte mittels einer Presse, die mit einem eine Drainageeinrichtung aufweisenden Pressraum und einem antreibbaren Pressorgan versehen ist.The invention relates to a method for controlling the juicing of organic products by means of a press which is provided with a press chamber having a drainage device and a drivable press member.
Zu diesem Zwecke werden vornehmlich mechanisch, pneumatisch oder hydraulisch betätigte Pressen verwendet, wobei das Pressorgan vorwiegend als Kolben oder flexible Membran ausgebildet ist. Der gesamte Pressvorgang erfolgt in mehreren Presszyklen, die in sich folgenden Intervallen abgewickelt werden.For this purpose, mainly mechanically, pneumatically or hydraulically operated presses are used, the pressing member being predominantly designed as a piston or flexible membrane. The entire pressing process takes place in several pressing cycles, which are carried out in subsequent intervals.
Während eines Presszyklus' wird das Pressorgan vorerst beharrlich gegen die im Pressraum vorkommende Maische gepresst und anschliessend wieder in eine Ruhelage zurückgezogen. Während dieser Rückhubbewegung wird die Maische aus Obst, Trauben oder dgl. Früchten beispielsweise durch Rotation des Pressbehälters während einer gewissen Zeit aufgelockert.During a pressing cycle, the pressing member is first pressed persistently against the mash occurring in the pressing room and then pulled back into a rest position. During this return stroke movement, the mash of fruit, grapes or the like is loosened for example by rotating the press container for a certain time.
Bei dieser diskontinuierlichen Arbeitsweise ist der erforderliche zeitliche Aufwand bei der zu entsaftenden Maischecharge für den wirtschaftlichen Nutzen einer Presse von entscheidender Bedeutung.With this discontinuous method of operation, the time required for the mash batch to be juiced is of crucial importance for the economic benefit of a press.
Darunter versteht man eine hohe Saftausbeute bei möglichst kurzer Gesamtverweilzeit für den Prozess unter Vermeidung schädlicher Auswirkungen auf den gewonnenen Saft.This means a high juice yield with the shortest possible total dwell time for the process while avoiding harmful effects on the juice obtained.
Diese Forderung stellt aufgrund ihrer Vielfältigkeit hohe Ansprüche an die Aufgabenstellung. Es stellt sich somit dem Fachmann die Aufgabe, ein Verfahren zur Steuerung der Entsaftung organischer, vornehmlich landwirtschaftlicher Produkte wie Obst, Gemüse, Trauben oder dgl. Früchten mittels einer Presse zu schaffen, mit dem durch eine hohe Saftausbeute bei relativ kurzer Gesamtverweilzeit und ohne Qualitätsverluste ein hoher wirtschaftlicher Nutzen erzielt werden kann.Due to its diversity, this requirement places high demands on the task. It is therefore the task of the person skilled in the art to create a method for controlling the juicing of organic, primarily agricultural products such as fruit, vegetables, grapes or the like.Fruits by means of a press, with which a high juice yield results in a relatively short overall residence time and without loss of quality high economic benefits can be achieved.
Gleichzeitig soll die zu erbringende Lehre die Durchführung idealer Entsaftungsprozesse und die Einsparung an Energieaufwand und Verschleiss vermitteln.At the same time, the apprenticeship to be carried out should convey the implementation of ideal juicing processes and the savings in energy expenditure and wear.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass der Presshub eines Presszyklusses frühestens bei Erreichen der aus der während diesem Presszyklus gewonnen maximalen Saftleistung beendet wird.According to the invention, this object is achieved in that the pressing stroke of a pressing cycle is ended at the earliest when the maximum juice output obtained from this pressing cycle is reached.
Der Presszyklus dauert seit dem ünterbruch des Presshubes des vorangegangenen Presszyklusses und schliesst den Rückhub des Pressorganes sowie eine allfällige Auflockerungsphase und den Presshub dieses Presszyklusses ein.The pressing cycle has lasted since the pressing stroke of the previous pressing cycle was interrupted and includes the return stroke of the pressing member as well as a possible loosening phase and the pressing stroke of this pressing cycle.
Von der Anwendung des erfindungsgemässen Verfahrens ist der nach dem Befullen der Presse erste Presszyklus insofern beteiligt, als dass durch ihn, unmittelbar bei Erreichen der maximalen mittleren Saftleistung mit dem Ende dieses Presshubes das verfahrensmässige Vorgehen gestartet wird.The first pressing cycle after the press has been filled is involved in the use of the method according to the invention, in that it starts the procedural procedure immediately upon reaching the maximum average juice output at the end of this pressing stroke.
Die Dauer eines Presszyklusses richtet sich nach der maximalen mittleren Saftleistung zweier sich folgender Presszyklen, wobei die mittlere Saftleistung der gewonnenen Saftleistung in der dazu verbrauchten Zykluszeit als Durchschnittswert entspricht. Der Beginn des nächsten Presszyklus' erfolgt nach Beendigung des Presshubes, indem der Rückhub des Pressorganes eingeleitet wird.The duration of a pressing cycle depends on the maximum average juice output of two subsequent pressing cycles, the average juice output corresponding to the juice output obtained in the cycle time used for this purpose as an average value. The start of the next press cycle takes place after the end of the press stroke by initiating the return stroke of the press member.
Die maximale mittlere Saftleistung LQ eines Presszyklusses errechnet sich aus der während einer bestimmten Zeit gewonnenen Saftmenge Q pro Zeiteinheit, die zu Beginn des Presshubes stärker ansteigt und aufgrund der abnehmenden Pressbarkeit des Pressgutes anschliessend den Maximalwert der Saftleistung erreicht. An dieser kritischen Stelle ist eine optimale Wirtschaftlichkeit bei jedem einzelnen Presszyklus erreicht.The maximum average juice output LQ of a pressing cycle is calculated from the amount of juice Q obtained per unit of time over a certain period of time, which increases more strongly at the beginning of the pressing stroke and then reaches the maximum value of the juice output due to the diminishing compressibility of the pressed material. At this critical point, optimal economy is achieved with every single press cycle.
Eine weitere Verbesserung der Wirtschaftlichkeit über mehrere Presszyklen bei der Entsaftung landwirtschaftlicher Produkte, die durch Versuche bestätigt wurde, kann dadurch erreicht werden bzw. tritt dann ein, wenn der Presshub eines Presszyklusses erst nach Erreichen der aus diesem Presszyklus gewonnenen maximalen mittleren Saftleistung LQ (K0...Kx) beendet wird. Diese allgemeine Definition nimmt Rücksicht auf den nachfolgenden Presszyklus, dessen maximale mittlere Saftleistung erfahrungsgemäss unter derjenigen des vorausgegangenen Zyklusses liegt, und mindert die Saftleistungsdifferenz zweier Presszyklen zugunsten der Wirtschaftlichkeit des Verfahrens.A further improvement in the economy over several pressing cycles in the juicing of agricultural products, which has been confirmed by tests, can thereby be achieved or occurs if the pressing stroke of a pressing cycle only after the maximum average juice output LQ (K 0 ) obtained from this pressing cycle has been reached ... K x ) is ended. This general definition takes into account the subsequent press cycle, the maximum average juice output of which is known to be lower than that of the previous cycle, and reduces the juice output difference of two press cycles in favor of the economy of the process.
Eine weitere Begünstigung kann dann erzielt werden, wenn der Presshub eines Presszyklusses nicht nach der zu erwartenden maximalen mittleren Saftleistung LQ (Kv) des nächstfolgenden Presszyklusses beendet wird, wodurch der schonenden Maischebehandlung Rechnung getragen wird.A further benefit can be achieved if the pressing stroke of a pressing cycle is not ended after the expected maximum average juice output LQ (K v ) of the next pressing cycle, which takes account of the gentle mash treatment.
Optimal erweist es sich, den Presshub eines Presszyklusses zu beenden, wenn die momentane Saftleistung Q die zu erwartende maximale mittlere Saftleistung LQ des nächsten Presszyklusses erreicht, sodass ein üeberpressen der Maische bei günstigen wirtschaftlichen Bedingungen vermieden werden kann. Diese Vorgehensweisen gründen auf dem Vergleich der momentanen Saftleistung mit der zu erwartenden maximalen mittleren Saftleistung des nächsten Presszyklusses und eignen sich vorzüglich bei der Entsaftung von Obst, Früchten, Trauben oder anderen landwirtschaftlichen Produkten.It turns out optimally to end the pressing stroke of a pressing cycle when the current juice output Q reaches the expected maximum average juice output LQ of the next pressing cycle, so that over-pressing of the mash can be avoided under favorable economic conditions. These procedures are based on the comparison of the current juice output with the expected maximum average juice output of the next press cycle and are particularly suitable for the juicing of fruit, fruits, grapes or other agricultural products.
Als Einrichtung erweist sich eine Presse der Gestalt vorteilhaft, bei welcher die Saftauslassanordnung bzw. die Saftsammeleinrichtung einen die die Presse verlassende Saftmenge feststellende Messeinrichtung aufweist, die mit einem Prozessor und dieser wiederum mit einer die Antriebsorgane der Presse steuernden Vorrichtung verbunden ist.As a device, a press of the design has proven to be advantageous in which the juice outlet arrangement or the juice collecting device has a measuring device which determines the amount of juice leaving the press and which is connected to a processor and this in turn to a device controlling the drive elements of the press.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der anschliessenden Beschreibung und der Zeichnung, auf die bezüglich aller nicht im Text beschriebenen Details ausdrücklich verwiesen wird. Es zeigen:Further details and advantages of the invention result from the subsequent description and the drawing, to which express reference is made to all details not described in the text. Show it:

Fig. 2 eine schematische Darstellung des erfindungsgemässen Verfahrens in verbesserter Ausführung.Fig. 2 is a schematic representation of the inventive method in an improved version.
Fig. 1 vermittelt in zeichnerischer Darstellung den Ablauf des Verfahrens zur Steuerung der Entsaftung organischer Produkte, vornehmlich Obst, Früchte, Trau ben oder dgl. landwirtschaftlicher Produkte mittels einer Presse anhand einer Menge (Q) - / Zeit (T) - Diagramms. Während dem ersten Presszyklus innerhalb der Zeit To bewegt sich das Pressorgan aus der Ruhestellung gegen die Maische und verharrt so lange in der Pressstellung, bis die maximale mittlere Saftleistung LQ aus diesem Presszyklus erreicht worden ist. Die Saftausbeute ist anfänglich stärker zunehmend und flacht später ab, wobei die Saftmenge Q sich stetig vergrössert, währenddem andererseits die mittlere Saftleistung, d.h. die bis zum angenommenen Zeitpunkt erreichte durchschnittliche Saftmenge nach Erreichen ihres Maximalwertes sich abnehmend entwickelt. Neben diesen Parametern verläuft die Kurve der momentanen Saftleistung Q am Anfang steil ansteigend und fällt nach Erreichen der maximalen Leistung mit annähernd gleicher Steilheit ab und asymptotisch aus. Unterhalb des Scheitelpunktes der Q-Kurve befindet sich der Wechselpunkt auf der mittleren Saftleistungskurve, wonach die zunehmend ansteigende mittlere Saftleistung %sich in einen gegen den Scheitelpunkt flacheren Abschnitt übergeht und danach wieder abfällt. Der Scheitelpunkt ist gleichzeitig die Schnittstelle der mittleren Saftleistung LQ und der momentanen Saftleistung Q, die mit einem Durchflussmengenmesser und Rechner festgestellt wird. Ab diesem Zeitpunkt soll der Pressvorgang beendet und der nächste Presszyklus eingeleitet werden. Dieser beginnt mit dem Rückzug des Pressorgans und ist in Fig. 1 innerhalb des Zeitintervalls T1 dargestellt. Schon während dem Rückzug des Pressorgans kann auch die Auflockerung der Maische, beispielsweise durch Drehen des Pressbehälters einsetzen. Der Rückzug des Pressorgans ist in Fig. 1 durch die Zeichen TR und die Auflockerung durch TA bezeichnet. Die Dauer der einzelnen Presszyklen richtet sich nach dem Verfahrens ablauf, sie ist variabel. Mit zunehmenden Presszyklen reduziert sich die momentane Saftleistung.Fig. 1 provides a graphic representation of the sequence of the method for controlling the juicing of organic products, primarily fruit, fruits, maid ben or the like. Agricultural products by means of a press based on a quantity (Q) / time (T) diagram. During the first pressing cycle within the time T o , the pressing member moves from the rest position against the mash and remains in the pressing position until the maximum average juice output LQ from this pressing cycle has been reached. The juice yield initially increases more and later flattens, with the amount of juice Q increasing steadily, while on the other hand the average juice output, ie the average amount of juice reached up to the assumed point in time, decreases after reaching its maximum value. In addition to these parameters, the curve of the current juice output Q increases steeply at the beginning and, after reaching the maximum output, falls with almost the same slope and is asymptotic. Below the apex of the Q curve is the change point on the middle juice performance curve, after which the increasing increasing average juice performance% changes into a section which is flatter towards the apex and then drops again. The vertex is at the same time the interface of the average juice output LQ and the current juice output Q, which is determined with a flow meter and computer. From this point in time, the pressing process should be ended and the next pressing cycle initiated. This begins with the withdrawal of the pressing member and is shown in Fig. 1 within the time interval T 1 . The loosening of the mash, for example by rotating the press container, can already start during the withdrawal of the pressing member. The retraction of the pressing member is indicated in FIG. 1 by the characters T R and the loosening by T A. The duration of the individual press cycles depends on the process process, it is variable. The current juice output decreases with increasing pressing cycles.
Fig. 2 stellt den erfindungsgemässen Verfahrensablauf mit gegenüber der Vorgehensweise von Fig. 1 verzögertem Presszyklenbeginn dar, d.h. der Rückhub des Pressorgans erfolgt nach erreichter maximaler mittlerer Saftleistung. Diese Massnahme beruht auf der Tatsache, dass im Verlauf des Pressvorganges die Saftleistungen der Presszyklen sich reduzieren. Zur Vermeidung eines hohen, die Wirtschaftlichkeit des Pressvorganges beeinträchtigenden Saftleistungsgefalles, kann durch eine nach dem erzielten Maximalwert eingeleitete Stillegung oder Rückhubbewegung der mittleren Saftleistungen an den nächstfolgenden Presszykϊus erzielt werden, wobei sich diese Vorgehensweise auf die Wahrscheinlichkeit eintretender Erfahrungswerte stützen muss. Dabei ist zu beachten, dass durch die zeitliche Verzögerung Ky der aus dem nächstfolgenden Presszyklus zu erwartende maximale mittlere Saftleistungswert nicht unterschritten wird. Alternativ kann der Presshub eines Presszyklusses dann beendet werden, wenn die momentane Leistung Q mit der zu erwartenden maximalen mittleren Saftleistung des nächsten Presszyklusses übereinstimmt.FIG. 2 shows the process sequence according to the invention with the start of the pressing cycle being delayed compared to the procedure of FIG. 1, i.e. the return stroke of the pressing member takes place after the maximum average juice output has been reached. This measure is based on the fact that the juice performance of the pressing cycles is reduced in the course of the pressing process. In order to avoid a high drop in juice output which affects the economy of the pressing process, the average juice output at the next pressing cycle can be achieved by decommissioning or return stroke movement after the maximum value achieved, whereby this procedure must be based on the probability of empirical values occurring. It should be noted that the time delay Ky does not fall below the maximum average juice output value to be expected from the next pressing cycle. Alternatively, the pressing stroke of a pressing cycle can be ended when the instantaneous power Q corresponds to the expected maximum average juice output of the next pressing cycle.

Selbstverständlich könnte auch ein Schwimmer, Ultraschall oder eine Druckdose am Boden der Auffangwanne zur Messung der Niveauänderungen in der Auffangwanne verwendet werden. Aufgrund der von einem Prozessor registrierten Werte, wird auf die Antriebsorgane der Presse 9 steuernd 8 Einfluss genommen. Am Ende jedes Presszyklusses wird die Auffangwanne 3 über eine separate Leitung 10 entleert, wobei dazu ein von dem Prozessor oder von Hand ansteuerbarer Schieber 11 vorgesehen ist.
