Abstract

The Parent Patent described the thermal treatment of sticky materials, esp of wheat gluten in a flash dryer by hot air in concurrent or counterflow. The material to be treated is mixed outside the dryer with already dried particles in a ratio of 1:2-1:5 and reduced in size at the same time. The final drying then takes place in the flash dryer. The addition patent achieves a substantial redn in power consumption and a shorter drying time which helps to preserve the vitality of the gluten.

Description

Verfahren zur thermischen Behandlung von weichgummiartigem, knetbarem und klebrigem Gut, insbesondere Vital-Weizengluten Die Erfindung betrifft ein Verfahren zur thermischen Behandlung von weichgummiartigem, knetbarem und klebrigem Gut, insbesondere Vital-Weizengluten, wobei das Gut in einen Trockner, vorzugsweise Stromtrockner, im Gleich-oder Gegenstrom zur Heißluft eingespeist wird und die Trocknung unter Verwendung von bereits getrockneten Gutsteilchen erfolgt, nach Patent .. .. ... (Patentanmeldung P 27 36 549.7).Process for the thermal treatment of soft rubber-like, kneadable and sticky goods, in particular vital wheat gluten. The invention relates to a method for the thermal treatment of soft rubber-like, kneadable and sticky goods, in particular Vital wheat gluten, whereby the goods are put in a dryer, preferably a flow dryer, is fed in cocurrent or countercurrent to the hot air and the drying under Use of already dried good particles takes place, according to patent .. .. ... (Patent application P 27 36 549.7).

Das zu behandelnde Gut wird nach dem Hauptpatent in mit bereits getrockneten Gutsteilchen in einer Partikelgröße von 10 bis 500 » angereicherte Heißluft von 1100C bis 1700C eingedüst, wobei das Gut durch Monopumpen in Zweistoffdüsen gefördert und die Verdüsung mittels Druckluft durchgeführt wird.According to the main patent, the goods to be treated are already dried Good particles with a particle size of 10 to 500 »enriched hot air from 1100C to 1700C, the material being conveyed by monopumps in two-fluid nozzles and the atomization is carried out by means of compressed air.

Durch dieses. Verfahren ist ein schonendes und kurrzzeitiges Trocknen von weichgummiartigem, knetbarem und klebrigem Gut möglich.Because of this. The process is gentle and short-term drying of soft rubber-like, kneadable and sticky goods possible.

Allerdings ist der ENer.gieverbrauch relativ hoch. Durch die Zusatzerfindung soll -das Verfahren so gestaltet werden, daß der Energieverbrauch wesentlich reduziert und zur noch besseren Erhaltung der Vitalität des Gutes die Trocknungszeit verkürzt ist.However, the energy consumption is relatively high. Through the additional invention - the process should be designed in such a way that the energy consumption is significantly reduced and the drying time is shortened in order to maintain the vitality of the goods even better is.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das zu behandelnde Gut und bereits getrocknete Gutsteilchen im Gewichtsverhältnis 1 : 2 bis 1 : 5 außerhalb des Trockners gemischt und gleichzeitig zerkleinert werden und dieses Gemisch zur Endtrocknung dem Trockner zugeführt wird. Zum Mischen und Zerkleinern kann das zu behandelnde Gut einem hochtourigen Vertikal-Schneid-Mischer, der ein-oder zweistufig gefahren werden kann, zugeführt werden.According to the invention this object is achieved in that the to be treated Good and already dried good particles in a weight ratio of 1: 2 to 1: 5 outside the dryer mixed and crushed at the same time and this mixture for Final drying is fed to the dryer. For mixing and chopping that can be too material to be treated a high-speed vertical cutting mixer, which is one or two-stage can be driven.

Durch die Zerkleinerung des zu behandelnden Gutes und durch das Mischen mit den bereits getrockneten Gutsteilchen ist es möglich, den H20-Gehalt des mischgutes bereits im Vertikal-Schneid-Mischer auf 16 bis 35 % zu senken Durch das. erfindungsgemäße Verfahren ist eine Energieeinsparung bis zu 50 % möglich Außerdem wird durch die Zerkleinerung des zu behandelnden Gutes -außerhalb des eigentlichen Trockners sowie durch die Mischung mit bereits getrockneten .Gutsteilchen eine wesentliche Verkürzung der eigentlichen Trocknung in der Heißluft erreicht, was sich gunstxg auf. die Vitalität des Gutes auswirkt. By crushing the material to be treated and by mixing With the already dried material it is possible to determine the H20 content of the mixed material to reduce already in the vertical cutting mixer to 16 to 35% The process enables energy savings of up to 50% to be achieved Shredding of the material to be treated - outside of the actual dryer as well as due to the mixture with already dried .good particles a significant shortening the actual drying in the hot air is achieved, which is beneficial to. the vitality of the good.

Das Verfahren wird an einer zu seiner Durchführung dienenden Vorrichtung im folgenden näher beschrieben. Die Zeichnung zeigt als Ausführungsbeispiel einen Strontrocknex mit seitlich -ange-ördnetem Schneid-Mischer im Vertikal schnitt Das zu behandelnde Gut..1, insbesondere Vital-Weizengluten und QuellstErke, wird durch Monopumpen mit 1,5 bis 5 bar in den Ver.tikal-Schneid-Mischer 10 eingebracht, wo es mit den über die Trockengutzuführung.11 zugeführten, bereits getrockneten Gutsteilchen im Gewichtsverhältnis 1 : 2 bis 1 : 5 gemischt und gleichzeitig durch die Schneidmesser 9 zerkleinert wird. Das entstandene Gemisch wird direkt in den Heißluftstrom 2 des Stromtrockners zur Endabtrocknung auf den gewünschten Restfeuchtegehalt eingeführt. Der Querschnitt des Stromtrockners erweitert sich konisch in Richtung der durchströmenden Heißluft 2 um 70 und verengt sich dann wieder um 150 jeweils zur Senkrechten. Die Durchmesser d1 und d1 vor der konischen Erweiterung und nach der Verengung sind identisch. Das getrocknete Gut wird zusammen mit der Heißluft über die Gutabführung 8 einem Abscheideorgan, beispielsweise einem Zyklon und/oder einer Schlauchfilterkombination zugeführt.The process is carried out on a device that is used to carry it out described in more detail below. The drawing shows an exemplary embodiment Strontrocknex with side-angled cutting-mixer in vertical cut That Gut..1 to be treated, in particular vital wheat gluten and swelling starch, is through Monopumps with 1.5 to 5 bar introduced into the vertical cutting mixer 10, where it with the already dried product particles fed in via the dry product feeder.11 mixed in a weight ratio of 1: 2 to 1: 5 and at the same time through the cutting knife 9 is crushed. The resulting mixture is directly into the hot air stream 2 of the Electric dryer introduced for final drying to the desired residual moisture content. The cross section of the electric dryer widens conically in the direction of the flowing through Hot air 2 by 70 and then narrows again by 150 in each case to the vertical. the Diameters d1 and d1 are before the conical enlargement and after the narrowing identical. The dried material is transported together with the hot air via the material discharge 8 a separator, for example a cyclone and / or a bag filter combination fed.
