Description

Schnellprüfer für Getreide, fehl und ähnliche Stoffe mit Trockenschrank und Pendelgewichtswaage. Es sind Trockenschränke bekannt, bei denen die Schalen zur Aufnahme des Probegutes hineingestellt werden oder an einer Waage in den Trockenraum hineinhängen. Bisher wurden diese zu trocknenden Proben während des Trockenprozesses in möglichster Ruhe gehalten; meist, wenn sie an einerWaage hingen, zu diesem Zwecke noch arretiert und der Trockenraum bis zur beendeten bzw. ange--nornmenen Beendigung der Trocknung möglichst abgeschlossen gehalten.Quick checker for grain, wrong and similar substances with drying cabinet and pendulum weight scale. There are drying cabinets known in which the trays to take the sample or placed on a scale in the drying room hang in. Previously, these samples to be dried were during the drying process kept as calm as possible; mostly when they were hung on a scale, for this purpose still locked and the drying room up to the finished or accepted termination the drying is kept as complete as possible.

Das Wesen der vorliegenden Erfindung beruht darin, daß innerhalb des Trockenraumes verschieden heiße Zonen geschaffen werden und daß die Proben während der Trocknung selbsttätig durch die Gewichtsabnahme die verschiedenen Zonen des Trockenraumes pendelnd durchwandern.The essence of the present invention resides in the fact that within the Drying room different hot zones are created and that the samples during the different zones of the drying process automatically due to the weight loss Hike through the drying room pendulously.

An Hand der Zeichnung sei die Erfindung wie folgt - beschrieben An einem runden oder eckigen Trockenschrank a, welcher von einer Heizquelle (Spiritus- oder Petroleumlampe, Gas oder Elektrizität) regulierbar beheizt wird, ist eine Pendelwaage so angebracht oder danebengestellt, daß. der die Probeschale d haltende Pendelarm P durch einen Schlitz s in den Trockenraum hängt.With reference to the drawing, the invention is as follows - described An a round or square drying cabinet a, which is powered by a heat source (alcohol or kerosene lamp, gas or electricity) is controllably heated, is a pendulum balance so attached or adjacent that. the pendulum arm holding the sample cup d P hangs through a slot s in the drying room.

Die Skala g der Waage erhält die Einteilung derart, daß bei einem bestimmten Quantum Probegut (bei dem Beispiel xo g) oben der Zeiger f auf der Nullstrichgravierung steht. Bei der Gewichtsabnahme sinkt der Zeiger f und jeder Strich der Skala zeigt beispielsweise die Gewichtsabnahme um 1/"o g an. Da jedes Zehntelgramm z Prozent der =o g des Probegutes bedeutet, ist auf der Skala ständig ersichtlich, wie-viel Prozent Feuchtigkeit die Probe in den verschiedenen Stadien der Trocknung verloren hat.The scale g of the scales is graded in such a way that with one certain quantity of sample (in the example xo g) the pointer f on the zero line engraving stands. As you lose weight, the pointer f goes down and each line on the scale shows for example, the weight loss by 1 / "o g. Since every tenth of a gram z percent which means = o g of the sample, you can always see how much on the scale Percent moisture the sample is lost in the various stages of drying Has.

Die Heizquelle c ist nun so abgestimmt, daß sie unten im Schranke die Höchsttemperatur erzeugt, die von' dem eingebrachten, die Feuchtigkeit enthaltenden Probegut gerade noch ertragen werden kann, ohne der Gefahr des Verbrennens ausgesetzt zu sein. Sobald die Probe aber etwas austrocknet, würde ein Verbrennen eintreten. Sie muß deshalb in die oberen, kühleren Zonen des Schrankes übergeführt werden. Damit dies selbttätig geschieht, ist nach vorliegender Erfindung dio Waage zum Trockenschranke so angeordnet, bezüglich ihrer Empfindlichkeit so eingestellt und die Länge des in den Trockenraum ragenden Pendelarmes so gewählt, daß während der Trocknung bzw. des Leichterwerdens des Probegutes letzteres von unten nach oben den Trockenraum durchpendelt, die Probe selbsttätig aus der unteren heißesten Zone in die gemäßigteren Zonen emporsteigt.The heating source c is now tuned so that it is below the barrier the maximum temperature produced by the one introduced containing the moisture Sample material can just be endured without being exposed to the risk of burns to be. But as soon as the sample dries out a bit, it would burn. It must therefore be transferred to the upper, cooler areas of the cabinet. In order for this to happen automatically, according to the present invention, the scales for the drying barrier so arranged, adjusted with regard to their sensitivity and the length of the The pendulum arm protruding into the drying room is chosen so that during drying or the lightening of the sample, the latter from bottom to top the drying room The sample oscillates automatically from the lower hottest zone to the more moderate Zones ascending.

Daraus ergeben sich die Vorteile; daß bedeutend höhere Temperaturen zur Trocknung als früher angewendet werden können, so daß die Austrocknung bei der vorliegenden Erfindung wesentlich schneller vor sich geht, wobei durch das freipendelnde Fortziehen der Trockenprobe von der Heizquelle nach den oberen gemäßigteren Zonen ein Anbrennen vermieden wird.This gives rise to the advantages; that significantly higher temperatures can be used for drying than before, so that the dehydration in the present invention is much faster, with the free swinging Removing the dry sample from the heating source after the upper more moderate Zones a burn is avoided.
