The fermentation system is charged with 10 l of deionized water after installation of the gas-introduction and agitator element under test. Here are the 82131 on how to enable JavaScript in your web browser.

These include the heating system, gas mixing station and the pressure control valve. Annotation of standard text DIN Fluid systems and components for general use Agitators intensify the heat exchange between the thermostatting elements and the fermentation broth.

In contrast to the type 1 inclined-blade agitator, the inclined-blade agitator idn 2 was designed with a narrower but longer paddle surface.

Continuous curve high solidity hydrofoil impeller.

BACKGROUND OF THE INVENTION

You have no items in your shopping cart. Depending on the requirements of the measurement control instrumentation of the fermentation, a pO 2 electrode, a pH electrode, a temperature sensor Dlna sampling valve CV 25a turbidity probe and pCO 2 electrode can be used. Impeller assembly with asymmetric concave blades.

These corrections apply to this standard: This has hydrodynamic properties coalescence behaviour, oxygen saturation concentration similar to the medium. Usually, a cylindrical vessel is used. The oxygen transport coefficient k L a is determined according to the following formula: The agitator blades 1 may consist of several segments 5and the angles of attack of each segment may be different.

Reaction vessels and their components. Each segment was 32 centimeters in length. Sustainable Development Goals and standardisation, how do they connect?

An agitator according to claim 1, wherein the agitator has two to eight agitator blades. Three 25 mm and two 19 mm Ingold ports are let into the vessel wall laterally. In addition, the electrical energy supply is included in the supply unit. JavaScript is required for the online shop to function fully.

Axial-flow impeller for mixing liquids. In contrast to the inclined-blade agitator type 2, the outer segments were bent in the same direction C shape. An agitator blade 1 may consist of equally large segments 5with different angles of attack.

Agitators and baffles for agitator vessels; types, terms and main dimensions. The dinn transport coefficient k L a is determined according to the following formula:. Preferably, the agitator blades 1 are fixed to a blade mount 3 which serves to receive the agitator shaft 4. Disc agitators are also disclosed in DE 23 49 and DE 23 51 Such a blade mount 3 having agitator blades 1 fixed thereto is termed dn element hereinafter.

An agitator according to claim 1, wherein the acute angle of the upper segment and the acute angle of the lower segment are complementary.

Domestic and commercial equipment. Report error on page. A SumoBrain Solutions Company. It is preferred that the angles of attack of the segments of an agitator blade be the same as the angles of attack for the segments of each additional agitator blade, although, as previously mentioned, the angle of attack of one segment of an agitator blade may be different than the angle of attack of a different segment of the same agitator blade.

The test liquid used in the experiments was 0. The subject invention will now be described in terms of its preferred embodiments.
