  Verfahren zur Reinigung von Zuckerroheaft. 



   Im Patente Nr. 53270 ist ein Verfahren zur Reinigung von Zuckerrohsaft beschrieben, dessen Wesen darin besteht, dass dem eventuell durch Ätzkalk alkalisch gemachten, auf zirka 700 C vorgewärmten Rohsaft nebst gebranntem oder gelöschtem Kalk natürlicher, kohlensaurer Kalk unter innigem Rühren beigemischt wird, worauf der verbleibende Ätzkalküberschuss aussaturiort und gemeinsam mit dem zugesetzten kohlensauren Kalk abfiltriert wird. 



   Es hat sich nun herausgestellt, dass eine noch weitergehende Reinigung der Säfte und weitere Ersparnis an   Ätzkalk   erzielt wird, wenn man das Kalksteinmehl bereits in der Diffusion zusetzt. Hiebei erfolgt eine Ausfällung von   Nichtzuckerstoffen,   welche un-

 fällung im späteren Stadium erspart sowie gleichzeitig ein höherer Nährwert der ausgelaugten Schnitte herbeigeführt. 



   In der Rübenverarbeitung wird am zweckmässigsten das Kalksteinmehl den Schnitten auf dem Transportgut zugesetzt oder   gleichmässig   mit den Schnitten in den Diffuseur zugeführt. Die Menge des Zusatzes an Kalksteinmehl richtet sich nach der Azidität des Saftes, so zwar, dass der Saft noch eine schwache Azidität   behält. Die Weiterbehandlung   des Saftes erfolgt entweder mit Ätzkalt oder vorteilhafter mit   Ätzkali.   und Kalksteinpulver in der im Patente Nr. 53270 geschilderten Weise.

  Process for cleaning raw sugar stems.



   Patent No. 53270 describes a process for purifying raw sugar juice, the essence of which is that natural carbonate of lime is mixed with the raw juice, possibly made alkaline by quick lime and preheated to approx remaining caustic lime excess is ausaturiort and filtered off together with the added carbonate of lime.



   It has now been found that an even more extensive cleaning of the juices and further savings in quick lime is achieved if the limestone powder is already added during diffusion. This results in a precipitation of non-sugar substances, which
 EMI1.1
 There is no need for felling at a later stage and, at the same time, a higher nutritional value of the depleted cuts is brought about.



   In beet processing, the limestone flour is most expediently added to the cuts on the transported goods or fed evenly with the cuts into the diffuser. The amount of limestone powder added depends on the acidity of the juice, so that the juice still retains a weak acidity. The further treatment of the juice takes place either with caustic cold or, more advantageously, with caustic potash. and limestone powder in the manner set forth in Patent No. 53270.

PATENT-ANSPRÜCHE : Abänderung des Verfahrens nach Patent Nr. 53270, dadurch gekennzeichnet, dass der gepulverte Kalkstein schon zur Dinusion zugesetzt und der so gewonnene Robsaft entweder, wie üblich, mit Ätzhalk oder mit Atzkalk und Kalksteinemehl Behandelt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIMS: Modification of the process according to patent no. 53270, characterized in that the powdered limestone is already added to the dinusion and the rob juice obtained in this way is either treated, as usual, with caustic lime or with caustic lime and limestone powder. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
