Description

Tellertrockner mit Dampfbeheizung. Bei den gebräuchlichen mit Wasserdampf beheizten Tellertrocknern hat sich der Mißstand gezeigt, daß in den oberen Tellern eine weit größere Wärmeentziehung aus dem Dampf vor sich geht als in den unteren Tellern. Diese Erscheinung ist darauf zurückzuführen, daß der Wärmeübergang zwischen Dampf und Trockengut auf den oberen Tellern wegen des größeren Temperaturunterschiedes größer ist als auf den unteren Tellern mit dem bereits vorgetrockneten Gut.Plate dryer with steam heating. The common ones with steam heated plate dryers the problem has shown that in the upper plates there is a far greater extraction of heat from the steam than in the lower ones Plates. This phenomenon is due to the fact that the heat transfer between Steam and dry food on the upper plates because of the greater temperature difference is larger than on the lower plates with the already pre-dried goods.

Um den Trockenprozeß zu beschleunigen, ist es also erforderlich, die Dampfzufuhr zu den Heizkammern der oberen Teller möglichst reichlich zu gestalten. Dies hat man dadurch zu erreichen gesucht, daß man den oberen Tellern heißeren oder höher gespannten Dampf, auch Frischdampf gesondert zuführte, was eine teuere und umständliche Betriebsführung bedingte.In order to accelerate the drying process, it is necessary that Make the steam supply to the heating chambers of the upper plate as plentiful as possible. This has been tried to achieve that the upper plates or hotter higher tensioned steam, also live steam separately supplied, which is an expensive and inconvenient operational management.

Durch die Erfindung werden diese Mängel beseitigt, und zwar dadurch, daß Abgase ohnehin vorhandener Feuerungen vor Abzug in den Kamin mit dem frisch aufgegebener, auf den oberen Tellern befindlichen Trockengut in Berührung gebracht werden.The invention eliminates these deficiencies by, that exhaust gases from already existing firing systems before being drawn into the chimney with the fresh brought into contact with abandoned dry goods located on the upper plates will.

Hierbei kann die Ausbildung des Trockners so getroffen werden, daß die oberen Teller nicht als Hohlkörper ausgebildet werden und die Dampfheizung in diesen Tellern fortfällt. Für die Erfindung ist dies jedoch belanglos.Here, the design of the dryer can be made so that the upper plate is not designed as a hollow body and the steam heating in falls away from these plates. However, this is irrelevant for the invention.

In der Zeichnung ist eine beispielsweise Ausbildung des Tellerofens zur Durchführung des neuen Verfahrens dargestellt.The drawing shows an example of a design of the plate oven for the implementation of the new procedure.

Mit a sind die als Dampfzuführungs- bzw. Dampfabführungsrohre ausgebildeten Säulen bezeichnet, an welchen in bekannter Weise die einzelnen als Hohlkörper ausgebildeten ringförmigen Teller angeschlossen sind. Erfindungsgemäß sind beispielsweise die oberen sieben Teller b in einem besonderen Raum untergebracht, an dem ein Rohr d angeschlossen ist. Der erwähnte abgeteilte obere Raum c ist außerdem an den Kamin e angeschlossen, so daß die durch das Rohr d in den genannten Raum eingeführten Rauchgase, die einer ohnehin vorhandenen Feuerung entnommen werden können, durch den Kamin ins Freie gelangen. Die Rauchgase kommen in direkte Berührung mit dem zu trocknenden Gute und geben an dieses den größten Teil der Wärme ab, so daß die oben geschilderte Verdampfung des Wassers aus dem Gute auf den oberen Tellern beschleunigt wird und die Mängel beseitigt werden. Über die nicht in dem Raum c abgeschlossenen Teller streicht wie in bisher üblicher Weise Luft, welche das verdampfte Wasser zum Schornstein abführt.With a are designed as steam supply or steam discharge pipes Columns referred to, on which in a known manner the individual formed as a hollow body annular plates are connected. According to the invention, for example the upper seven plates b are housed in a special room on which a tube d connected. The above-mentioned partitioned upper room c is also close to the fireplace e connected, so that those introduced through the pipe d into said space Flue gases that can be taken from an already existing furnace through get outside the chimney. The smoke gases come into direct contact with the Good to be dried and give off most of the heat to this, so that the The above-described evaporation of the water from the property on the upper plates is accelerated and the shortcomings will be eliminated. About those not locked in the room c As usual, the plate removes air, which removes the evaporated water leads to the chimney.

Es ist selbstverständlich entgegen dem Ausführungsbeispiel auch möglich, die zur Verdampfung des Wassers herangezogenen Rauchgase getrennt von der übrigen Wrasenabfuhr abzusaugen.It is of course also possible, contrary to the exemplary embodiment, the smoke gases used to evaporate the water are separated from the rest Extract the vapor discharge.
