  Verfahren zur Gewinnung der Nichtzuckerstoffe aus Rohsäften der Rohrzuckerindustrie. 



   Nach dem bisher geübten Verfahren wurde der Rohsaft der Rohrzuckerindustrie (Kolonialzuckerindustrie) mit geringen Quantitäten von Kalk versetzt und der Klärung überlassen ; der so unvollkommen geklärte Saft welcher oft mechanische Verunreinigungen enthielt,. wurde zur Verdampfung gefühlt, während der feste Rückstand der Klärer auf Pressen unvollkommen abgepresst wurde, da sich das Produkt als ungemein schwer filtrierbar erwies. 



   Dieser Rückstand der bedeutende Mengen von Zuckerkalk, Proteinen, Wachs usw. enthält, ist minderwertig ; es wurde zwar eine Trennung des Wachses vom Defekationsschlamm angestrebt ; das Verfahren erwies sich aber als technisch schwer durchführbar. 



   Gegenstand vorliegender Erfindung bildet nun ein Verfahren mit welchen die wertvollen Nichtzuckerstoffe aus dem Rohsafte vor der Behandlung mit Kalk ausgeschieden werden. Gemäss der Erfindung wird folgend vorgegangen- : Der nach dem   Press-oder Diffusions-   verfahren erzeugte Rohsaft der Rohrzuckerindustrie wird auf geeigneten Apparaten bis zur Koagulation der Eiweissstoffe angewärmt, hierauf rückgekühlt und dann auf Rührwerke gebracht und mit einer Chlorkalziumlösung versetzt, und zwar mit so viel als es die im Safte sich   vorfindenden Nichtzuckerstoffe   erheischig machen und die ausgeschiedenen Nichtzuckerstoffe auf Filterpressen abgeschieden. Die Filtration geht glatt vor sich. Der so erhaltene Saft wird nunmehr auf üblicher Weise in bekannter Art weiter behandelt.

   Der durch die   C12   Ca-Lösung erhaltene Niederschlag wird zur Wachsgewinnung herangezogen.

  Process for the extraction of non-sugar substances from raw juices in the cane sugar industry.



   According to the previously practiced procedure, the raw juice of the cane sugar industry (colonial sugar industry) was mixed with small quantities of lime and left to be clarified; the so imperfectly clarified juice which often contained mechanical impurities. was felt to evaporate, while the solid residue of the clarifier was pressed incompletely on presses, as the product proved to be extremely difficult to filter.



   This residue, which contains significant amounts of sugar lime, proteins, wax, etc., is inferior; A separation of the wax from the defecation sludge was sought; however, the process turned out to be technically difficult to carry out.



   The subject of the present invention now forms a process with which the valuable non-sugar substances are eliminated from the raw juice before treatment with lime. According to the invention, the following procedure is followed: The raw juice of the cane sugar industry produced by the pressing or diffusion process is heated in suitable apparatus until the proteins coagulate, then cooled down and then put on stirrers and mixed with a calcium chloride solution, namely with that much when the non-sugar substances found in the juice make it necessary and the excreted non-sugar substances are deposited on filter presses. The filtration goes on smoothly. The juice obtained in this way is then further treated in the usual way in a known manner.

   The precipitate obtained from the C12 Ca solution is used to obtain wax.
