Description

Verfahren zum Trocknen von Gummi- und Regeneratfellen Der Leitgedanke fast sämtlicher neuzeitlicher Trockenanlagen für Rohgummi u. dgl. ist der, daß man das Trockengut in feuchter Atmosphä re auf die erforderliche Temperatur bringt und die Fertigtrocknung des so geheizten Trockengutes in trockener Atmosphäre vor sich gehen läßt, wodurch eine schnellere Erwärmung des Materials stattfindet, da die Wärme infolge der Feuchtigkeit schneller und tiefer in die Rohgttmmifelle eindringt und die Bildung einer isolierend wirkenden, klebrigen Oberfläche verhindert wird.Process for drying rubber and regenerated fur The guiding principle almost all modern drying systems for raw rubber and the like is that one brings the dry goods to the required temperature in a moist atmosphere and the finished drying of the goods heated in this way in a dry atmosphere lets go, whereby a faster heating of the material takes place, since the Due to the moisture, heat penetrates faster and deeper into the raw hide and the formation of an insulating, sticky surface is prevented.

Um diesen Erfolg zu erreichen, sind bei den bekannten Trockenverfahren umständliche und kostspielige Einrichtungen erforderlich, wie z. B. Dampfdüsen und Kondensationsapparate, die zur Regelung der in dem Trockenraum herrschenden Feuchtigkeit dienen sollen, oder mechanisch angetriebene Transportvorrichtungen, die das Trockengut in kontinuierlicher Bewegung einem eingeblasenen Luftstrom nach dem Gegenstromprinzip entgegenführen.In order to achieve this success, the known drying processes are used cumbersome and expensive facilities required, such as B. steam nozzles and Condensation apparatus used to regulate the humidity in the drying room are to serve, or mechanically driven transport devices that carry the dry goods in continuous movement a blown air flow according to the counterflow principle lead towards.

Wieder andere Verfahren sind auf künstliche Luftzirkulation angewiesen, die umfang" reiche Apparaturen erfordern.Still other methods rely on artificial air circulation, which require extensive equipment.

Hierdurch ergeben sich verschiedene Nachteile. u. a. geringe Trockenleistung, große Wärmevergeudung und großer Raumbedarf.This results in various disadvantages. i.a. low drying performance, large waste of heat and large space requirements.

Diese Mängel werden gemäß der Erfindung dadurch beseitigt, daß die Erwärmung des Gummis während der ersten Phase der Trocknung durch Beheizung der Trockenkammer bewirkt wird. Die gebildeten Dämpfe werden sodann zwecks Fertigtrocknung in an sich bekannter Weise abgesaugt.These deficiencies are eliminated according to the invention in that the Warming of the rubber during the first phase of drying by heating the Drying chamber is effected. The vapors formed are then used for final drying sucked off in a known manner.

NN achstehend wird beispielsweise eine Ausführungsform des Verfahrens beschrieben. Die nassen Rohgummi- oder Regeneratfelle werden außerhalb desTrockenraumes auf fahrbare Gestelle aufgehängt und mit den Gestellen eingefahren, so daß der ganze Raum von den auf den Gestellen befindlichen Fellen ausgefüllt wird. Die Trockenkammer enthält eine Rohrheizung, durch welche die Trockentemperatur (75 bis 8o° und höher) erzeugt wird. Infolge dieser Erhitzung verdampft das den Gummifellen anhaftende Wasser, und die Luft im Trockenraum wird stark mit Feuchtigkeit beladen, so daß im Trockenraum in kürzester Zeit die Atmosphäre hervorgerufen wird, welche die erste Phase des Trockenprozesses, nämlich die schnelle Durchwärmung in feuchter Luft, außerordentlich begünstigt.The following is an example of an embodiment of the method described. The wet raw rubber or regenerated pelts are outside of the drying room hung on mobile racks and retracted with the racks, so that the whole Space is filled by the skins on the racks. The drying chamber contains a pipe heater, through which the drying temperature (75 to 8o ° and higher) is produced. As a result of this heating, what adheres to the rubber heads evaporates Water, and the air in the drying room is heavily loaded with moisture, so that the first atmosphere is created in the drying room in a very short time Phase of the drying process, namely rapid warming in moist air, extraordinarily favored.

Sobald die vollkommeneDurchwärmung der Rohgummi- oder Regeneratfelle erreicht ist, wird ohne weitere Hilfsmittel lediglich mit einem kleinen Ventilator die feuchte Luft abgesaugt und die zweite Phase durchgeführt. Der ganze Trockenprozeß einschließlich Beschicken und Entleeren der Kammer dauert 2, höchstens 2'12 Stunden. Durch die Möglichkeit, die Temperatur in der Kammer auf der früheren Höhe zu halten und eine zweite Gruppe von Gestellen während der ersten Trocknung vorzubereiten, ist ein ununterbrochener Betrieb und infolgedessen die bestmögliche Ausnutzung des Trockenraumes gewährleistet.As soon as the raw rubber or regenerated skins are completely heated is reached, without any further aids, just a small fan sucked the moist air and carried out the second phase. The whole drying process including loading and emptying of the chamber takes 2, at most 2'12 hours. By being able to keep the temperature in the chamber at the previous level and prepare a second set of racks during the first drying, is an uninterrupted one Operation and, as a result, the best possible Utilization of the drying room guaranteed.
