Description

Verfahren zur Erzeugung eines Futters und eines Düngemittels bei der Reinigung der Rohsäfte, Schnitzelpreßwässer u. dgl. der Zuckerfabrikation. Der durch Schwefeleng der Rohsäfte, Abpreßwässer u. dgl. entstehendie aschearme (bis unter 4. Prozent) Niederschlag ändert schon bei äußerst schwachem Alkalisieren (o,oi) des Saftes mit Kalk seine Zusammensetzung derart, daß er oft über 30 Prozent und sogar bis zu 50 Prozent Asche (hauptsächlich Silikate) aufweist. Um also einen als Futter sicher verwertbaren Niederschlag zu erzeugen, muß der bei der Schwefeleng entstehende Niederschlag für sich; besonders vom Safte getrennt werden. Der so getrennte Niederschlag weist aber nur unbedeutende Mengen Phosphorsäure auf. Um die im Rohsafte u. dgl. enthaltene Phosphorsäure in Form eines möglichst konzentrierten Düngemittels herauszubekommen, muß die Phosphorsäure vor der eigentlichen Scheidung niedergeschlagen werden, es muß also eine Vorschefdüng des Saftes mit möglichst kleinen Kalkmengen (gewöhnlich genügt eine Alkalität von o,oi bis o,o2) durchgeführt werden. Der bei dieser Vorschdidung entstehende Niederschlag, welcher sich. ganz leicht filtrieren läßt (beinahe frei von Albumin- und Pektinstoffen), weist bis 8 und über 8 Prozent P2 O, auf.Process for the production of a fodder and a fertilizer in the purification of raw juices, schnitzel press water and the like in sugar production. The low-ash (up to 4 percent) precipitate that arises from the sulphurous concentration of the raw juices, press water and the like changes its composition even if the juice is slightly alkalized (o, oi) with lime, so that it is often over 30 percent and even up to Contains 50 percent ash (mainly silicates). So in order to produce a precipitate that can be safely used as fodder, the precipitate that arises in the case of Schwefeleng must for itself; especially separated from the juice. The precipitate separated in this way only contains insignificant amounts of phosphoric acid. In order to extract the phosphoric acid contained in the raw juice and the like in the form of a fertilizer that is as concentrated as possible, the phosphoric acid must be precipitated before the actual separation; , o2). The precipitate that arises during this predecision, which is. Can be filtered very easily (almost free of albumin and pectin substances), has up to 8 and over 8 percent P2 O.

Es ist zwar bereits bekannt, Zuckerrohrsäfte zwecks Reinigung zunächst mit schNvefl.iger Säure zu behandeln, zu filtrieren, das Filtrat mit soviel Kalk zu versetzen, daß @die Flüssigkeit schwach alkalisch wird und sodann den gebildeten Niederschlag für sich zu filtrieren, wobei sich :die Säure mit dem Kalk zu einem unlöslichen Salz vereinigt. Auch das Ausfällen der Eiweißstöffe aus Diffusionssäften u. digl durch. Behandeln mit schwefliger Säure und Verwertung des Niederschlages als Futtermittel :ist nicht neu. Ferner hat man bereits die bei der Behandlung von Zuckerrohsäften mit Kalk gebildeten, die Phosphorsäure des Saftes enthaltenden Niederschläge (Scheideschlamm) als Düngemittel verwertet. Bai vorliegendem Verfahren kommen zwar diese einzelnen an sich bekannten Maßnahmen ebenfalls zur Anwendung; es handelt sich jedoch -dabei in ersterLinie um,dieGewinnung von zwei Nebenprodukten der Saftreinigung, nämlich eines eiweißreichen und aschearmen Futters und eines pliiosphorsäurereichen Düngemittels, d. h. um einen Rdi'nigungsvorgang, der zur gleichzeitigen Erzeugung eines Futter- und Düngemittels führt und der das eine Produkt in besonders reiner, das andere in besonders konzentrierter Form liefert. Das vorliegende Verfahren unterscheidet sich also von den bisher bekannten durch folgende Merkmale: i. Gleichzeitige Erzeugung zweier Produ.kte, eines Futters und eines Düngemlittels; 2. Anreicherung :des Futtermittels an Eiweiß-, Pektin- und Fettstoffen (durch Herabsetzung des Gehaltes an anderen Stoffen) ; 3. Herabsetzung des Aschegehaltes des Futtermittels; q.. Konzentrierung der im Safte enthaltenen Phosphorsäure zu einem etwa 8 Prozent P. O, enthaltenden Düngemittel. rWhile it is already known to use sugar cane juices for cleaning initially to treat with quick acid, to filter, the filtrate with so much lime to move that @ the liquid becomes weakly alkaline and then the formed To filter precipitate by itself, whereby: the acid with the lime to one insoluble salt combined. Also the precipitation of proteins from diffusion juices and digl through. Treat with sulphurous acid and utilize the precipitate as feed: is not new. Furthermore, one already has those in the treatment of Raw sugar juices formed with lime and containing precipitates containing the phosphoric acid in the juice (Separation sludge) used as fertilizer. Bai the present proceedings come these individual measures known per se are also used; it deals however, the main focus is on the recovery of two by-products of juice purification, namely a protein-rich and ash-poor feed and a phosphoric acid-rich Fertilizer, d. H. about a cleaning process that leads to the simultaneous generation of of a feed and fertilizer and which carries one product in a particularly pure, the other delivers in a particularly concentrated form. The present procedure is different thus differ from the previously known by the following features: i. Simultaneous generation two products, a fodder and a fertilizer; 2. Enrichment: of the feed of protein, pectin and fatty substances (by reducing the content of other Fabrics); 3. Reduction of the ash content of the feed; q .. Concentration of the phosphoric acid contained in the juice to about 8 percent P. O, containing fertilizers. r
