Description
Verfahren zum Betriebe durch Feuergase beheizter Walzentrockner zur Herstellung von Kartoffelflocken Walzentrockner zur Herstellung von Kartoffelflocken sind an sich bekannt, auch solche Walzentrockner, welche durch Feuergase,. die mit großer Geschwindigkeit unter der Einwirkung des Schornsteinzuges durch einen Ringmäntel hindurchströmen, beheizt werden.Process for operating drum dryers heated by fire gases Production of potato flakes Roller dryer for the production of potato flakes are known per se, including those drum dryers, which by fire gases. with high speed under the action of the chimney draft through a ring jacket flow through, be heated.
Die Erfindung betrifft einen Walzentrockner; bei welchem die Feuergase durch die Tätigkeit eines besonderen Ventilators mit sehr großer Geschwindigkeit durch enge Kanäle hindurchgeführt werden, so daß die Wärmeabgabe pro Flächeneinheit noch wesentlich erhöht wird und die Abwärme noch zur Erzeugung von Dampf zum Dämpfen der zu trocknenden Kartoffeln sowie zur Beheizung weiterer kleinerer Trockenwalzen oder für ähnliche Zwecke verwendet werden kann.The invention relates to a drum dryer; at which the fire gases by the action of a special fan at a very high speed be passed through narrow channels, so that the heat dissipation per unit area is still increased significantly and the waste heat is still used to generate steam for steaming the potatoes to be dried and for heating other smaller drying rollers or can be used for similar purposes.
Der Vorteil der Erfindung besteht darin, däß durch Fortfall der hohen Anschaffungs-und Unterhaltungskosten der Dampfkesselanlage auch mittleren und kleineren landwirtschaftlichen Betrieben und Genossenschaften die Herstellung der als Futtermittel geschätzten Kartoffelflocken ermöglicht wird, da ein großer Teil der Verbraucher in der Lage ist, sich eine derartige Anlage anschaffen zu können. Da die Anlage geringes Gewicht hat, kann sie auch auf ein Fahrzeug montiert und so von Gehöft zu Gehöft geschafft werden und auf genossenschaftlicher Grundlage Verwendung finden.The advantage of the invention is that by eliminating the high Acquisition and maintenance costs of the steam boiler system are also medium-sized and smaller farms and cooperatives producing the as feed appreciated potato flakes is made possible by a large part of the consumer is able to purchase such a system. Because the plant has low weight, it can also be mounted on a vehicle and from a homestead be brought to homestead and used on a cooperative basis.
Auf der Zeichnung ist ein Ausführungsbeispiel der Anlage gemäß der Erfindung dargestellt In der Abbildung bedeutet a die Feuerung; b die Trockenwalze, c den Dampferzeuger und d den Ventilator.In the drawing is an embodiment of the system according to Invention shown In the figure, a means the furnace; b the drying roller, c the steam generator and d the fan.
Die Trockenwalze b besitzt in ihrem Umfang enge Durchlaßkanäle h, welche entweder in die Wandung eingezogen sind oder durch den Zwischenraum zwischen der Innenwand der Walze und einer in diese eingezogenen Büchse g gebildet werden. Die Heizgase treten seitlich in diese Durchlässe l2. ein und verlassen dieselben in der Mitte durch Sammelkanäle i.The drying roller b has narrow passages h in its circumference, which are either drawn into the wall or through the space between the inner wall of the roller and a sleeve g drawn into it. The heating gases enter these passages l2 from the side. one and leave the same in the middle through collecting channels i.
Die Heizgase müssen die Durchlaßkanäle h infolge ihres geringen Querschnitts mit hoher Geschwindigkeit durchströmen, wobei eine gleichmäßige Erwärmung der Walze eintritt. Ungleichmäßige Wärme führt leicht zum Rösten der Flocken, die dadurch an Wert erheblich verlieren.The heating gases must h due to their small cross-section flow through at high speed, with uniform heating of the roller entry. Uneven heat easily leads to the toasting of the flakes, which this causes lose their value considerably.
Die Rohre e und k sind zweckmäßig gegen Wärmeausstrahlung geschützt und münden so in die Walze, daß ein Eintreten von Falschluft vermieden wird. In die Zuleitung e kann bei Verwendung minderwertiger Brennstoffe ein Abscheider für Ruß und Flugasche' eingebaut werden.The pipes e and k are expediently protected against heat radiation and open into the roller in such a way that the entry of false air is avoided. In the feed line e can be a separator for the use of inferior fuels Soot and fly ash 'are incorporated.
Die Anlage ist so berechnet, daß die Heizgase bei Verlassen der Trockenwalze noch heiß genug sind; um. den für die Kartoffeldämpfung erforderlichen Dampf, der auch für andere Zwecke noch benutzt werden kann, zu erzeugen.The system is calculated in such a way that the heating gases leave the drying roller are still hot enough; around. the steam required for potato steaming, the can also be used for other purposes.
