   Wie oben ausgeführt, genügt in der Regel Luftleere allein, d. h. absoluter Druck

 kann nur bei einigen sehr voluminösen Materialien der Fall soin, welche in ihrer Schichtung   sehr viele lileine bezw. iin anderen   Falle relativ grosse   Zwichenräl1mc bilden   und so den   Druckströmen   der Flüssigkeiten wenig Widerstand entgegensetzen. 



   In den Fällen nun, wo aus ziemlich   voluminösen   Materialien ein konzentrierter Saft gewonnen werden soll, muss das Verhältnis der Menge dieses Materials zur Flüssigkeitsmenge günstiger gestaltet werden ; zu dem   Zwecke bleiben, wie   soeben ausgeführt, die (durch Pressung durch Schnecke B) ohnehin verringerten Zwischenräume der Bagasse nicht in der ganzen Lünge des Gefässes D mit Verdrängungsflüssigkeit gefüllt, z. B. von der   Stelle X   bis zum Mantel k1, so dass vom Mantel G1 ab bis zur   Stelle X   die in den 
 EMI5.3 
 von Bagasse gedrückt. 



   Um nun aber den erforderlichen Druck zu schaffen, müssen die von Flüssigkeit freibleibenden Zwischenräume vom Mantel G1 bis zur Stelle X durch ein Gas unter   höherem   als Atmosphärendruck   8usgefttllt werden   ; es sind dafür geeignet Dampf von geringer Spannung,   komprimierte   Luft. 



   Das mit dem Dampf zugleich - dann natürlich heisse - Wasser kann in den mit Dampf gefüllten Zwischenräumen herabsickern, wenn es die Temperatur des Dampfes an genommen hat.

   As stated above, evacuation alone is usually sufficient, i. H. absolute pressure

 can only be the case with some very voluminous materials, which in their layering have a lot of purple lines or In other cases they form relatively large spaces and thus offer little resistance to the pressure currents of the liquids.



   In those cases where a concentrated juice is to be obtained from fairly voluminous materials, the ratio of the amount of this material to the amount of liquid must be made more favorable; For this purpose, as just stated, the gaps between the bagasse, which are already reduced (by pressing by screw B), are not filled with displacement liquid over the entire length of the vessel D, e.g. B. from the point X to the coat k1, so that from the coat G1 to the point X in the

 pressed by bagasse.



   However, in order to create the required pressure, the spaces from the jacket G1 to the point X that remain free of liquid must be filled with a gas at a pressure higher than atmospheric pressure; low tension steam, compressed air, is suitable for this.



   The water at the same time as the steam - then naturally hot - can seep down into the spaces filled with steam when it has reached the temperature of the steam.
