Description

Verfahren zur Herstellung von Cellulosernehl Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Cellülosemehl. Nach älteren Vorschlägen des Erfinders wird zum Zwecke der Gewinnung von Futtermitteln weitgehend zerkleinertes Holz oder ähnliche zellstoffhaltige Pflanzenteile einer Aufschlußl)ehandlung, z. B. mit Bisulfitlauge, unterworfen, his die Masse beim Vermahlen in amorphe Teilchen zerfällt.Method of making cellulose flour The invention relates to focuses on a process for the production of cellulose flour. According to older proposals of the inventor is largely crushed for the purpose of obtaining animal feed Wood or similar cellulose-containing plant parts from a digestion, e.g. B. with bisulfite liquor, subjected until the mass when grinding into amorphous particles disintegrates.

Für viele technische Zwecke liegt Bedarf nach reiner Cellulose in Form eines eine große Oberflächenentwicklung aufweisenden Celluloseinehls vor.There is a need for pure cellulose for many technical purposes Form of a cellulose shell having a large surface area.

Zur Erreichung dieses Zieles wird erfindungsgemäß die vorerwähnte Verarbeitung weitgehend zerkleinerten Holzes oder ähnlicher zellstoffhaltiger Pflanzenteile unter Erhitzen mit Bistilfitlösungen unter Druck in der Weise durchgeführt, daß vor dein 'Mahlen das Kochgut mit einer Alkalilösung behandelt wird.In order to achieve this goal, according to the invention, the aforementioned Processing of largely shredded wood or similar cellulose-containing plant parts carried out under heating with bistilfit solutions under pressure in such a way that Before grinding, the food is treated with an alkali solution.

Man unterwirft also celltiloselialtige Rohmaterialien in weitgehend zerfaserter Form, also z. B. geschliffenes und bzw. oder gemahlenes Holz (Holzstoa), geraspeltes Holz. Sägespäne oder auf irgendeinem anderen mechanischen Weg in feine Fasern und Faserbündel oder Faserlamellen (Hobelspäne) zerkleinertes Holz, einem Aufschluß mit einer Bisulfitlauge unter Druck und bei erhöhter Temperatur, bis das derartig behandelte Material beim insbesondere nassen Vermahlen in ungestaltete Faserbruchstücke zerfällt.So one subordinates cell siloselialtige raw materials to a large extent fiberized form, so z. B. sanded and / or ground wood (wooden stoa), grated wood. Sawdust or any other mechanical means into fine Fibers and fiber bundles or fiber lamellas (wood shavings) shredded wood, one Digestion with a bisulfite liquor under pressure and at elevated temperature until the material treated in this way, especially when wet, into unshaped Fiber fragments disintegrate.

Die Abstimmufig der Lauge, der Behandlungsdauer, der Temperatur und des Druckes richtet sich naturgemäß nach dein gerade zur Verarbeitung kommenden zerfaserten Ausgangsinaterial und mußjeweils durch in der Technilc übliche Vor-.bzw.
