Title
(DE) STRANGPRESSVERFAHREN UND STRANGPRESSE FÜR PFLANZLICHE KLEINTEILE
(EN) EXTRUSION METHOD AND EXTRUDER FOR SMALL PARTS OF PLANTS
(FR) PROCEDE D'EXTRUSION ET EXTRUDEUSE POUR DES PARTICULES VEGETALES
Abstract
(DE) Verfahren zum Strangpressen von pflanzlichen Kleinteilen (32) in einer Strangpresse (31), wobei die Kleinteile (32) taktweise in einen Füll- und Pressraum (10) der Strangpresse (31) eingefüllt und mit einem innerhalb der Taktzeit linear vor- und zurück bewegten und von einem drehenden Exzenterantrieb (34) angetriebenen Strangpresskolben (5) unter Verdichtung in einen Rezipienten (11) geschoben und in eine Folgestrecke (33) zur Nachbehandlung befördert werden, wobei der Exzenterantrieb (34) derart ausgelegt wird, dass je Takt der Anteil der Befüllzeit des Füll- und Pressraums (10) an der Taktzeit verlängert wird.
(EN) A method for extruding small parts of plants (32) in an extruder (31), wherein the small parts (32) are cyclically filled into a filling and pressing area (10) of the extruder (31) and are compressed and pushed into a receptacle (11) with the aid of an extrusion piston (5) which is moved back and forth in a linear manner and are conveyed on a subsequent path for post-treatment, wherein the eccentric drive (34) is configured in such a way that for each cycle the proportion of the filling time for the filling and pressing area (10) is extended in relation to the cycle time.
(FR) L'invention concerne un procédé pour l'extrusion de particules végétales (32) dans une extrudeuse (31). Les particules (32) sont amenées cycliquement dans une chambre de remplissage et de compression (10) de l'extrudeuse (31), sont poussées dans un récipient (11), tout en étant comprimées, au moyen d'un piston d'extrudeuse (5) entraîné par un entraînement à excentrique rotatif (34) et déplacé linéairement en avant et en arrière pendant la durée du cycle et sont acheminées dans un tronçon suivant (33) pour la poursuite du traitement. Selon l'invention, l'entraînement à excentrique (34) est réalisé de sorte que, à chaque cycle, la part du temps de remplissage de la chambre de remplissage et de compression (10) par rapport à la durée du cycle est allongée.
