Description

Verfahren zum Trocknen von Kartoffeln . Bisher wurden Kartoffeln entweder in rohem Zustande als Schnitzel unter der Einwirkung von Heißluft oder Feuergasen in Trommel-oder Hordentrocknern verschiedenster Bauart getrocknet, oder es wurde die Trocknung in der Weise vorgenommen, daß man die rohen Kartoffeln zerrieb und das Reibsel unter möglichst feiner Verteilung in warmer Luft zerstäubte. Auch wurden gekochte Kartoffeln auf Walzentrocknern zu Kartoffelflocken verarbeitet.Method of drying potatoes. So far, potatoes have been either in the raw state as schnitzel under the action of hot air or fire gases Dried in drum or tray dryers of various types, or it was the drying carried out in such a way that one grated the raw potatoes and atomized the rub with as finely a distribution as possible in warm air. Also were Boiled potatoes processed into potato flakes on drum dryers.

Keines dieser Verfahren befriedigte, denn einerseits sind die Erzeugnisse aus rohen Kartoffeln nicht hochwertig genug und anderseits ist die Herstellung der hochwertigeren Flocken zu teuer, weil der Dampfverbrauch für Walzentrockner außerordentlich hoch ist.Neither of these processes was satisfactory because, on the one hand, there are the products from raw potatoes not of high quality and on the other hand, the production of the High-quality flakes are too expensive because the steam consumption for drum dryers is extraordinary is high.

Es wurde nun gefunden, daß es möglich ist, ein den Kartaffelflocken gleichwertiges Erzeugnis herzustellen mit einer wesentlich einfacheren Vorrichtung und bei weit geringerem Dampfverbrauch.It has now been found that it is possible to use the potato flakes manufacture equivalent product with a much simpler device and with far less steam consumption.

Gemäß der Erfindung wird das Trockenverfahren in der Weise ausgeführt, daß man die Kartoffeln kocht und unter Dampfdruck versprüht. Zu diesem Zwecke werden die gewaschenen rohen Kartoffeln in ein Druckgefäß eingebracht, und alsdami wird Dampf eingeblasen, bis der Druck im Gefäß etwa 3 Atm. beträgt. Wenn diese Dampfspannung im Gefäß erreicht ist, sind die Kartoffeln gar gekocht und werden nun unter Dampfdruck in einen Raum gesprüht, gegebenenfalls unter Anwendung von Düsen, wobei schon aus geringer Höhe ein völlig trockenes Pulver zu Boden fällt.According to the invention, the drying process is carried out in such a way that you boil the potatoes and spray them under steam pressure. Be for this purpose the washed raw potatoes are placed in a pressure vessel, and then used Steam is blown in until the pressure in the vessel is about 3 atm. amounts to. When this vapor tension is reached in the vessel, the potatoes are cooked through and are now under steam pressure sprayed into a room, possibly using nozzles, with already out a completely dry powder falls to the ground.

Die zum Versprühen benutzte Vorrichtung ist vorteilhaft so ausgestaltet: Um die Zerkleinerung der Schalen zu ermöglichen und die den Kartoffeln anhaftenden Verunreinigungen, besonders Steine, zurückzuhalten und so das Versprühen durch Düsen zu erleichtern, ist das Druckgefäß mit einem Rührer ausgerüstet, dessen Flügel in Schrägstellung über eine der Austrittsöffnung vorgelagerten gelochten Platte streichen. Um weiter ein Verstopfen der Düse zu verhindern, können auch in oder vor der Düse Rührflügel angebracht sein.The device used for spraying is advantageously designed as follows: To allow the peel to be crushed and those sticking to the potatoes Holding back impurities, especially stones, and thus spraying through nozzles To make it easier, the pressure vessel is equipped with a stirrer, the blades of which are in Stroke the inclined position over a perforated plate in front of the outlet opening. To further prevent the nozzle from clogging, you can also use it in or in front of the nozzle Be attached impeller.

Um für große Leistungen in fortlaufendem Betriebsgange arbeiten zu können, kann man zwei oder mehrere Druckgefäße zusammenschalten und wechselweise beschicken und unter Druck setzen.To work for great accomplishments in continuous operation you can connect two or more pressure vessels together and alternately load and pressurize.

Die Arbeitsweise geht folgendermaßen vor sich: zooo kg gewaschene rohe Kartoffeln werden in das Druckgefäß eingefüllt, welches durch Einblasen von Dampf auf beispielsweise 7 Atm. gebracht wird. Wenn der Druck erreicht ist, was bei genügender Leistung des Dampfkessels schon in einigen Minuten möglich ist, sind die Kartoffeln gar gekocht. Nun wird der Rührer in Tätigkeit gesetzt und -der . so erzeugte Kartoffelbrei unter Dampfdruck durch eine Düse in den freien Raum gesprüht. Schon bei ganz geringer Fallhöhe fällt ein vollkommen trockenes Pulver aus, das den Kartoffelflocken gleichwertig ist.The procedure is as follows: zooo kg of washed Raw potatoes are poured into the pressure vessel, which is made by blowing in Steam to e.g. 7 atm. is brought. When the pressure is reached, what is possible in just a few minutes if the steam boiler has sufficient power the potatoes cooked through. Now the stirrer is put into action and the. so produced mashed potatoes under Steam pressure through a nozzle into the sprayed free space. Even at a very low height of fall, a completely dry one falls Powder that is equivalent to potato flakes.
