Abstract

The agitator is used for culture growth or fluid processing. A rectangular dish is agitated by an eccentric drive to move the fluid to and fro, while deflection surfaces are set in the dish to obtain the optimum amount of turbulence required for the particular fluid and process.

Description

Antrag auf Erteilung eines Patentes über ein Kippsystem zur Turbulenzerzeugung in Jldssiskeiten in flachen Behältern Bekanntlich werden Massenkulturen von Mikroorganismen unter anderem in flachen Becken betrieben. Die für eine ertragreiche Kultur notwendige Turbulenz wird hierbei durch Rühren der Kulturfldssigkeit erzeugt. Bei den verwendeten Rührsystemen geht ein hoher Energiebetrag zur Überwindung von Reibungawiderständen verloren, insbesonderte bei der Reibung zwischen Flüssigkeit und Rührmechanik.Application for a patent on a tilting system for generating turbulence In jars in shallow containers It is well known that there are mass cultures of microorganisms operated in shallow pools, among other places. The necessary for a productive culture Turbulence is created by stirring the culture liquid. The used Agitator systems require a large amount of energy to overcome frictional resistance lost, especially with the friction between the liquid and the stirring mechanism.

In dem hier dargestellten neuen System wird die Turbulenz dadurch erzeugt, daß die Kulturflüssigkeit in flachen rechteckigen Behältern mittels Kippschwingungen zum Fließen gebracht und durch Strömungswiderstämde aufgewirbelt wird (Abb. 1). Die Strömung folgt der Schwerkraft, die durch die alternierende Schräglage der Behälter zur Wirkung kommt. Die Strömungshindernisse werden so gestaltet und angeordnet, daß für die betreffende Flüssigkeit optimale Turbulenz erreicht wird, ohne daß es zu Stauungen und Sedimenten kommt. Die Behälter können bei Bedarf beleuchtet und/oder luftdicht verschlossen werden. Letzteres wird z.B. notwendig, wenn es auf eine optimale und kontrollierbare Begasung der Flüssigkeit ankommt.In the new system shown here, the turbulence is caused by this generated that the culture liquid in flat rectangular containers by means of tilting vibrations is brought to flow and whirled up by flow resistance (Fig. 1). The flow follows the force of gravity, which is created by the alternating inclination of the containers comes into effect. The flow obstacles are designed and arranged in such a way that that optimal turbulence is achieved for the liquid in question without it congestion and sediments occur. The containers can be illuminated and / or if necessary be hermetically sealed. The latter becomes necessary, for example, when it is at an optimal level and controllable gassing of the liquid arrives.

Die Behälter können prinzipiell in Jeder Größe konstruiert werden. Die Achse der Xippbewegungen verläuft in einer Symmetrieebene des Behälters, bei größeren Becken parallel zur Längsrichtung. Der Antrieb der rhythmischen Kippbewegungen erfolgt über einen geeigneten Exzenter, der über eine Schubstange am Behälter angreifen kann (Abb. 1). Mehrere Behälter können batterieartig übereinander oder/und nebeneinander angeordnet und mit demselben Antrieb bewegt werden. Dies macht das System für fabrikmäßigen Einsatz geeignet. Energie wird nur für die periodische Hebearbeit und zur Überwindung der Reibungswiderstände in der relativ einfachen Antriebsmechanik benötigt; in der Flüssigkeit selbst entstehen keiD Reibungsverluste.In principle, the containers can be constructed in any size. The axis of the Xipp movements runs in a plane of symmetry of the container, at larger pelvis parallel to the longitudinal direction. The drive of the rhythmic tilting movements takes place via a suitable eccentric, which attack the container via a push rod can (Fig. 1). Several containers can be placed on top of one another or / and next to one another in a battery-like manner arranged and moved with the same drive. This makes the system factory-like Suitable for use. Energy is only used for periodic lifting work and for overcoming the frictional resistance required in the relatively simple drive mechanism; in the There are no frictional losses in the liquid itself.

Patentanspruch: Turbulenzerzeugung in Flüssigkeiten in flachen Behältern mit Hilfe von periodischen Kippschwingungen und Strömungswiders tänden unter Aussetzung der Schwerkraft.Claim: Generation of turbulence in liquids in flat containers with the help of periodic tilting vibrations and flow resistance under exposure of gravity.

Anwendung: bei mikrobiologischen und technischen Verfahren.Application: in microbiological and technical processes.
