Description

DEUTSCHESGERMAN

Bei der Gewinnung von Flüssigzucker aus Datteln kann das Entkernen der Datteln nicht, wie es für Steinobst schon vorgeschlagen ist, mittels einer Siebzentrifuge durchgeführt werden, deren konische Siebtrommel entsprechend der Steingröße gelocht ist, weil 5 das Fruchtfleisch von Datteln von einer verhältnismäßig zähen Haut umschlossen ist und die Datteln zufolge ihres hohen Zuckergehaltes klebrig sind und zu Klumpen zusammenbacken, von denen sich das Fruchtfleisch nicht ohne weiteres löst.When extracting liquid sugar from dates, the pitting of the dates cannot, as it is for Stone fruit has already been proposed to be carried out by means of a sieve centrifuge whose conical sieve drum is perforated according to the size of the stone, because 5 the pulp of dates is proportionate to one tough skin and the dates are sticky due to their high sugar content and too Bake up lumps from which the pulp will not come off easily.

Es muß also beim Entkernen von Datteln mittels Zentrifugalkraft erstens dafür gesorgt werden, daß die Haut der Früchte geöffnet wird und zweitens, daß die Früchte in der Zentrifuge gewendet werden, damit die Verbindung zwischen den zähklebrigen Bestandteilen laufend unterbrochen wird.When pitting dates by means of centrifugal force, it must first be ensured that the skin of the fruit is opened and, secondly, that the fruit is turned in the centrifuge so that the connection between the sticky components is continuously interrupted.

Das Verfahren zum Lösen des Fruchtfleisches von Datteln von den Kernen durch Zentrifugieren der Früchte in einer der Steingröße entsprechend gelochten Siebtrommel besteht nach der Erfindung darin, daß die Früchte während des Zentrifugierens in einer Stufenzentrifuge mit heißem Druckwasser bzw. mit Dampf beaufschlagt werden, wobei es vorteilhaft ist, wenn die Früchte während des Passierens der Stufen der Zentrifuge mit heißem Druckwasser bzw. mit Dampf beaufschlagt werden.The process of loosening the pulp of dates from the kernels by centrifuging the According to the invention, fruit in a perforated drum screen corresponding to the size of the stone consists in that the fruits during centrifugation in a stage centrifuge with hot pressurized water or with Steam can be applied, and it is advantageous if the fruit while passing through the steps the centrifuge can be exposed to hot pressurized water or steam.

Zufolge der Anwendung einer Stufenzentrifuge werden die einzelnen Früchte beim Zentrifugieren mehrfach gewendet, und durch den Druckwasser- bzw. Dampfstrahl wird die Außenhaut verletzt, indem diese unter der Temperatureinwirkung platzt. Das Platzen der Außenhaut gibt die Voraussetzung dafür, daß sich das Fruchtfleisch überhaupt von den Kernen löst, und durch das Wenden wird erreicht, daß immer neue Stellen des Fruchtfleisches durch die Löcher der Siebtrommel abgeschleudert werden. Die in der Siebtrommel zurückgehaltenen Kerne werden periodisch oder kontinuierlich aus der Siebtrommel ausgeräumt. Das Druckwasser bzw. der kondensierte Dampf kann Verfahren zum Lösen des Fruchtfleisches von Datteln von den KernenAs a result of the use of a stage centrifuge, the individual fruits are centrifuged turned several times, and the outer skin is damaged by the pressurized water or steam jet bursts under the influence of temperature. The bursting of the outer skin is the prerequisite for that the pulp loosens from the pips at all, and by turning the pulp it is always new Places of the pulp are thrown through the holes of the sieve drum. The one in the sieve drum Retained cores are periodically or continuously removed from the sieve drum. The pressurized water or the condensed steam can process for loosening the pulp from dates from the kernels
