Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei dem Apparat zum Trocknen von feuchten und schleimigen Massen nach der Patentschrift 68313 sind mehrere Mulden derart über einander angeordnet, dafs "der sich in dem Trockengut der einen Mulde entwickelnde Wasserdampf gezwungen wird, immer unter der nächst höher liegenden Mulde entlang zu streichen und an diese seine Wärme abzugeben. Dabei wird die betreffende Mulde immer nur in ihrem unteren Theile von dem Wasserdampf umspült, und eine genügende Ausnutzung der Wärme des letzteren findet demnach nicht statt.In the apparatus for drying moist and slimy masses according to the patent 68313 several troughs are arranged one above the other in such a way that the "in the Dry material, the water vapor developing a trough, is always forced to go under the next higher trough paint and give off its warmth to it. The hollow in question is always only in its lower part lapped by the water vapor, and a sufficient utilization the warmth of the latter does not therefore take place.

Im Unterschiede hierzu besteht der nach vorliegender Erfindung besonders für mittlere und kleinere Betriebe in einfachster Weise construirte Apparat aus einer das Trockengut (Biertreber u. s. w.) enthaltenden, innen mit einer rotirenden Heiztrommel versehenen Mulde, die von einem Mantelkanal umgeben ist, in welchem der bei der Trocknung sich bildende Wasserdampf, durch eine in der ganzen Länge der Mulde vorgesehene Oeffnung eintretend, die Mulde vollkommen umkreist, bevor er ins Freie entweicht. Es wird also bei dieser Bauart die Wärme des Wasserdampfes in wesentlich erhöhtem Mafse zur Trocknung des Gutes nutzbar gemacht.In contrast to this, the one according to the present invention exists especially for medium-sized and smaller establishments in the simplest way constructed the apparatus from a dry material (spent grains u. s. w.) containing, inside provided with a rotating heating drum, the is surrounded by a jacket channel in which the formed during drying Water vapor entering through an opening provided along the entire length of the trough, completely circles the hollow before escaping into the open. So it will be with this type of construction the heat of the steam to a much greater extent for drying the goods made usable.

Wie aus dem auf der Zeichnung dargestellten Ausführungsbeispiel hervorgeht, besteht der Trockner aus einer einfachen Mulde a, in der ein in bekannter Weise zu heizendes und mit einem Schaufelwerk versehenes Röhrenbündel b drehbar angeordnet ist. Um die Mulde α ist in gewisser Entfernung ein Mantel c angeordnet, der oben in einen Kamin endet. Das zu trocknende Gut wird an einer oder mehreren Stellen auf einmal eingefüllt, wobei man die Klappe c1 in die punktirt gezeichnete Lage bringt, um zu verhindern, dafs ein Theil des Gutes in den Abzugskanal d für den Wasserdampf gelangt. Dann schliefst man die Klappe c1 wieder und setzt das Röhrenbündel b mit dem Schaufelwerk in Umdrehung. Der aus dem Trockengut entweichende Wasserdampf tritt dann in den Kanal d und wird um die Mulde a herumgeführt, wobei er; entweder einen Theil seiner Wärme an diese und somit auch an das Trockengut abgiebt, oder wenigstens die nach aufsen hin eintretenden Wärmeverluste der Trommel und des Materials vermindert, und dann erst durch den Kamin abzieht. Um eine noch gröfsere Wärmeausnutzung zu erzielen, kann der Abzugskanal d für den Wasserdampf auch mehrfach um die Mulde α herumgeführt werden.As can be seen from the embodiment shown in the drawing, the dryer consists of a simple trough a, in which a tube bundle b, which is to be heated in a known manner and is provided with a shovel mechanism, is rotatably arranged. Around the trough α a jacket c is arranged at a certain distance, which ends in a chimney at the top. The goods to be dried are poured in at one or more places at once, the flap c 1 being brought into the position shown in dotted lines, in order to prevent part of the goods from getting into the outlet duct d for the water vapor. Then one closes the flap c 1 again and sets the tube bundle b with the paddle in rotation. The water vapor escaping from the dry material then enters the channel d and is guided around the trough a , whereby it; either gives off a part of its heat to this and thus also to the material to be dried, or at least reduces the outward heat losses of the drum and the material, and only then withdraws it through the chimney. In order to achieve an even greater utilization of heat, the outlet channel d for the water vapor can also be routed around the trough α several times.
