Abstract

Powdered sugar or other finely divided materials liable to self adhesion is conditioned to prevent agglomeration and the formation of lumps when the ground material is stored in silos or packed, by introducing a steam of air of medium moisture content into the powdered sugar immediately after grinding, in such a way that the air gives rise to a fluidised bed and its temp. lies between the dew pt. on the surface of the sugar crystals and the temp. at which thermal changes of the sugar are initiated. The moisture content is pref. 60% and the air is at 15-40 degrees C.

Description

Verfahren zum Konditionieren von Puderzucker oder ähnlichem, zum Anhaften neigenden einkorngut ============ Die Erfindung bezieht sich auf ein Verfahren z Konditionieren von Puderzucker oder ähnlichem, zum Anhaften neigenden Feinkorngut zum Zwecke, das Zusammenbacken und Klumpen zu verhindern, wenn das vermahlene Gut versackt oder siliert wird. Process for conditioning powdered sugar or the like, for Einkorngut tending to stick ============ The invention relates to a method z Conditioning of powdered sugar or similar fine-grain goods that tend to stick for the purpose of preventing caking and lumping when the milled material is sunk or ensiled.

Es besteht das Bedürfnis, den Puderzucker nach dem Vermahlen so rieselfähig zu machen und zu erhalten, daß man ihn entsprechend den Erfordernissen des Vertriebes ohne weiteres manipulieren kann. Bisher war man gezwungen, den Puderzucker entweder sofort zu verwenden, zum Beispiel in der Schokoladenindustrie, Konditionierungsmittel, zum Beispiel Stärke oder Calciumphosphat, zuzugeben oder auSwendige Zwischenbehandlungen einzuschalten, zum Beispiel den Puderzucker nach dem Ermahlen in Sicke abzupacken, ihn längere Zeit zwischenzulagern und erst dann seine rieselfähig gebliebenen Teile in Verkaufspackungen abzufällen.There is a need to make the powdered sugar so free-flowing after grinding to make and maintain that one according to the requirements of the distribution can easily manipulate. Previously you were forced to use powdered sugar either to use immediately, for example in the chocolate industry, conditioning agents, for example starch or calcium phosphate, or extensive intermediate treatments to switch on, for example to pack the powdered sugar in a bead after grinding, to store it for a longer period of time and only then to store its remaining free-flowing parts to be disposed of in sales packages.

Diese Tischteile kann man gemäß der Erfindung dadurch vermeiden, daß der Puderzucker sogleich nach seinem Ermahien aus Kristallzucker einem Luftstrom mittlerer Feuchte übergeben wird, der die Bildung eines Wirbelbettes gestattet und eine Temperatur zwischen der der Taubildung an den Kristalloberflächen des Zuckers und derjenigen hat, die thermisch Veränderungen des Puderzuckers bewirkt. Vorzugsweise soll der Luftstrom aufsteigen, eine Temperatur von 15 bis 40°C und eine relative Luftfeuchte von weniger als 60 % besitzen.These table parts can be avoided according to the invention in that the powdered sugar immediately after its warmth from granulated sugar in a stream of air medium humidity is passed, which allows the formation of a fluidized bed and a temperature between that of dew formation on the crystal surfaces of the sugar and the one that causes thermal changes in powdered sugar. Preferably should the air flow rise, a temperature of 15 to 40 ° C and a relative Have a humidity of less than 60%.

Durch die Anwendung des erfindungsgemäß geführten Verfahrens wird das beim Ermahlen des Puderzuckers freiwerdende inkludierte Wasser dem Mahlgut durch Abf iihrung soweit entzogen, daß auf den Kristallflächen ein Zustand des, Feuchtigkeitsgleichgewichts entsteht, der ein Zusammenbacken des Puderzuckers an den Berührungspunkten verhindert und seine gute Rieself?iiligkeit sicherstellt.By using the method carried out according to the invention, the included water released when the powdered sugar is ground through the grist Discharge withdrawn so far that a state of moisture equilibrium on the crystal surfaces that prevents the icing sugar from sticking together at the points of contact and ensures its good flowability.

Das Verfahren bringt darüber hinaus den Vorteil eines ehr geringen Staubanfalles, da sich die kleinsten Staubpartikel auf der zunächst klebrigen Oberflache des ermahlenden Puderzuckers niederschlagen, dort eine Trocknung bewirken und die scharfkantigen Bruchflächen glätten.The method also has the advantage of being rather low Dust accumulation, as the smallest dust particles are on the initially sticky surface knock down the powdered sugar, cause drying there and the Smooth out sharp-edged fracture surfaces.

Weiterhin wird die Temperatur des frisch ermahlenen. Puderzuckers durch den verwendeten Lufstrom auf die gewinschte, vorzugsweise zur Lagerung erforderliche Tempsratur gebracht.It also keeps the temperature of the freshly ground. Powdered sugar by the air flow used to the desired, preferably required for storage Brought temperature.

Das erfahren ist praktisch erprobt worden in einem zylindrischen Standrohr von 0,) m Durchmesser, dessen perforiertor Trichterboden einen Auslaufstutzen hat. Durch den perforierten Boden wurde die Luft eingeblasen. Die Temperatur der Luft lag zwischen 15 bis 40°C bei einer relativen Luftfeuchte von höchstens 45 %. Der Puderzucker wurde sogleich nach der vermahlung dem Standrohr derart aufgegeben, daß sich eine Wirbelschicht von etwa 4 m Höhe ausbildete. Bei einem Durchsat von 800 kg/h gewann man ein Produkt, welches nach längerer Lagerzeit noch rieselfähig war und auch nach Abfüllen in Verkaufspackungen ausreichend lange unverklumpt blieb. Der auslaufstutzen des Stadnrohres war mit einem Drehschieber versehen, mit dem man den Durchsatz einstellen ist. Für die Konstanz des Betriebes sorgte ein Standhönenregler.This experience has been tested in practice in a cylindrical standpipe 0,) m in diameter, the perforated funnel bottom of which has an outlet nozzle. The air was blown in through the perforated floor. The temperature of the air was between 15 to 40 ° C with a relative humidity of at most 45%. Of the Immediately after grinding, powdered sugar was added to the standpipe in such a way that that a fluidized bed about 4 m high formed. With a throughput of 800 kg / h, a product was obtained which was still free-flowing after a long storage period was and remained unclumped for a long enough time even after filling in sales packs. The outlet of the Stadnrohres was provided with a rotary valve with the one is setting the throughput. A level regulator ensured the constancy of the company.

Das Verfahren ist sowohl kontinuierlich, wie oben beschrieben, als auch durchgeführt worden, indem portionsweise Puderzucker nach dem Vermahlen mit dem Luftstrom behandelt und dann der gesamte Inhalt entleert wurde.The process is both continuous, as described above, and Also been done by adding portions of powdered sugar after grinding with it treated with the air flow and then the entire contents evacuated.

Das Verfahren nach der Erfindung eignet sich zur Konditionierung auch anderer pulverförmiger oder feinkristalliner Stoffe, deren Lagerverhalten hinsichtlich der Erhaltung der Riselfähigkeit im wesentlichen von der Einlagerungstemperatur in Zusammenhang mit dem auf den Partikeloberflächen sich einstellenden Zustand des Feuchtgleichgewichts abhängig ist.The method according to the invention is also suitable for conditioning other powdery or finely crystalline substances, their storage behavior with regard to the preservation of the risability essentially depends on the storage temperature in connection with the state of the occurring on the particle surfaces Moist equilibrium is dependent.
