Patentirt im Deutschen Reiche vom 26. September 1882 ab.Patented in the German Empire on September 26, 1882.

Der Apparat bezweckt, atmosphärische Luft mittelst Wärme von ihrer normalen Feuchtigkeit zu befreien. Die Luft wird auf Blut- oder auf noch niedrigere Temperatur gebracht, um zum Trocknen von Baumwolle, Wolle, Leder, Papier, Tabak oder anderen Stoffen in einem Trockenraum verwendet zu werden. Bekanntlich übt stark erhitzte Luft auf Webstoffe, Früchte, Tabak, Leim, Fische, Chemikalien etc. eine so nachtheilige Wirkung aus, dafs die Anwendung einer natürlichen Trocknung unbedingt geboten • erscheint.The purpose of the apparatus is to remove atmospheric air from its normal humidity by means of heat to free. The air is brought to blood temperature or to an even lower temperature for drying cotton, wool, leather, paper, tobacco or other fabrics in one Drying room to be used. It is well known that strongly heated air affects textiles, fruits, Tobacco, glue, fish, chemicals, etc., have such a detrimental effect that their use natural drying is absolutely necessary.

Da dieses natürliche Trockenverfahren aber ein ■ langsames und ungewisses ist, so kommt es oft vor, dafs die betreffenden Stoffe bei wechselnder Temperatur Feuchtigkeit aufnehmen, wodurch besonders bei Nahrungsmitteln, die im Freien getrocknet werden und bei denen Dampfhitze nicht anwendbar ist, bedeutende Zeit- und andere Verluste und Unannehmlichkeiten entstehen, wie beispielsweise bei Klippfisch, der zum Austrocknen mehrere Tage gutes Wetter gebraucht, während hierzu bei ungünstiger Witterung zuweilen Wochen erforderlich sind. Klippfisch kann mittelst dieses Verfahrens bei beliebiger Witterung und gewöhnlicher Temperatur in ca. zwei Stunden auf das vollkommenste getrocknet werden und erhält dabei weifseres Aussehen und besseren Geschmack, als wenn er auf die jetzt übliche Weise der Einwirkung von Sonne, Regen, Staub und Wind ausgesetzt und oft hantirt worden wäre.But since this natural drying process is slow and uncertain, so comes it often happens that the substances in question absorb moisture when the temperature changes, This is particularly the case with foods that are dried in the open air and that require steam heat not applicable, significant time and other loss and inconvenience result, for example in the case of clipfish, which has several days of good weather to dry out used, while this sometimes takes weeks in bad weather. By means of this process, clipfish can be grown in any weather and normal temperature can be completely dried in about two hours and get whiter in the process Appearance and taste better than if it were acted in the now usual manner exposed to sun, rain, dust and wind, and often tampered with.

Der Apparat eignet sich ebenso für frisches Fleisch, welches sonst 48 Stunden lang einer Hitze von 70⁰C. bedarf, ehe es trocken genug wird, um verpackt zu werden; für Leim und Chemikalien, die beim Trocknen an der Luft den nachtheiligen Einflüssen des Witterungswechsels ausgesetzt sind; für Schuhe und Stiefel, anstatt sie vor ihrer Fertigstellung der Dampfhitze auszusetzen, wodurch oft die Qualität des Leders insofern leidet, als dasselbe schrumpft und seine Narbe rauh wird, so dafs die Waare ein schlechtes, rauhes Aussehen erhält; für Baumwollwaaren; für Wolle anstatt der Trocknung mittelst Dampfes, welche im Sommer sehr unangenehm ist und die Wolle spröde macht; für Tabak und Cigarren; für Wäsche und Holzstoff und für künstliche Dungmittel.The apparatus is also suitable for fresh meat, which otherwise ^{requires a heat of 70 °} C. for 48 hours before it becomes dry enough to be packed; for glue and chemicals that are exposed to the harmful effects of weather changes when drying in the air; for shoes and boots, instead of subjecting them to steam before they are finished, whereby the quality of the leather often suffers insofar as the leather shrinks and its grain becomes rough, so that the goods take on a bad, rough appearance; for cotton goods; for wool instead of drying by means of steam, which is very unpleasant in summer and makes the wool brittle; for tobacco and cigars; for laundry and wood pulp and for artificial manure.

A bezeichnet einen Ofen, der eine direct über der Feuerung angeordnete Kammer a hat; über dieser liegt wieder die Rauchkammer b mit Austrittsrohr c. Von der Feuerung aus geht eine Anzahl Rohre d durch die Kammer α hindurch nach der Rauchkammer, so dafs also der Rauch und die flüchtigen Verbrennungsproducte durch d nach b strömen. A denotes a furnace which has a direct over the furnace arranged a chamber; Above this is again the smoke chamber b with the outlet pipe c. From the furnace a number of pipes d go through the chamber α to the smoke chamber, so that the smoke and the volatile combustion products flow through d to b.

Das Rohr e führt aus dem oberen Theile der Kammer α nach einer im Kasten B angeordneten Rohrschlange/, die unten mit Luftöffnungen g versehen, ist. Aus dem oberen Theile des Kastens B führt ein Rohr h nach dem unteren Theile der Kammer a; ebenso communicirt die Rohrschlange/ unten mit einem Saugventilator c, um die Luft aus der Schlange zu saugen und sie durch ein Auslafsrohr i in die verticale hohle Welle k eines rotirenden Flügelgebläses D zu leiten. Letzteres besteht aus einer Anzahl radial auf k sitzender Flügel z. Zwischen diesen Flügeln sind an der hohlen Welle gekrümmte Auslafsöffnungen m angebracht, aus denen bei Rotation des Flügelgebläses die Luft aus derThe pipe e leads from the upper part of the chamber α to a pipe coil / arranged in the box B , which is provided with air openings g at the bottom. From the upper part of the box B a pipe h leads to the lower part of the chamber a; likewise the pipe coil / below communicates with a suction fan c in order to suck the air out of the coil and to direct it through an outlet pipe i into the vertical hollow shaft k of a rotating fan D. The latter consists of a number of radially seated wings on k z. Between these blades curved outlet openings m are attached to the hollow shaft, from which the air flows out of the when the blade fan rotates

Claims

The shaft flows against the blades ζ and is thereby properly distributed in the drying chamber E, which has a perforated bottom η at the bottom. A suction fan F is connected to room ο under E, the outlet pipe p of which leads upwards. Thus, when the furnace and the two suction fans and the wing fan are put into operation, the air in the chamber α can be warmed up enough to decompose its moisture (according to the inventor). The resulting gases go through the pipe coil and heat it, whereby the air flowing through the box B is heated, this heated air goes from here through the chamber a, which decomposes the moisture. The atmospheric gases, reduced to a low temperature (about 400 ° C. or less), are sucked out of the pipe coil by the suction fan, pass the hollow shaft k and emerge from m. The rotating blade fan distributes the air in the drying room over the objects to be dried in it. Here it is saturated with the moisture from the latter and is sucked out of the drying chamber by the suction fan. In Fig. 2, the coil and its box is not shown and its suction fan C is connected through a pipe r above with the air heating chamber of the furnace. The fan of the drying chamber has no curved outlet openings on its hollow shaft; the latter is open at the top so that the air can flow out and pass between the wings, whereby it is properly distributed. However, the shaft can also be provided with the lateral openings. A refrigerator or the like can also be arranged between the pipe coil or the furnace and its suction fan, or between the latter and the drying chamber, for cooling the air drawn in from the pipe coil. Patent claim: The apparatus represented by the drawing to free air from its moisture beforehand for drying purposes, essentially characterized by:

1. the combination of the chamber α , which is arranged in the furnace A above the furnace and provided with pipes d , with the pipe coil / in the box B , the suction fan C and the drying chamber £, through which arrangement the air in the chamber α and its moisture penetrate the heat and when flowing through the coil / has been decomposed, enters the drying chamber E in a dry state;

2. the installation of the chamber α of the furnace A with the furnace x, the smoke chamber b and the pipes d, which connect the furnace and the smoke chamber with one another and heat the air in the chamber α;
