The subject invention will now be described in terms of its preferred embodiments. Agitators also prevent the cells from sedimenting and thus being inhomogeneously distributed during the fermentation.

The inventive inclined-blade agitator SBR Type 3 is subdivided into three equal-sized segments. The oxygen transport coefficient k L a is determined according to the following formula: Please note that the selected standard 281331 invalid. The dimensions were as follows: Here are the instructions on how to enable JavaScript in your web browser. Shopping cart Close cart 0, foreach: DE 94 00 U discloses an agitator in which the agitator blades have an inner main blade connected with an outer side blade.

Our offices will be closed from December 24, to January 2, inclusive. The angle of attack of xin paddles of the type 1 inclined-blade agitator was variable. NS The number of pages: Aircraft and space vehicle engineering Click for automatic bibliography generation.

Usually, a cylindrical vessel is used. The number of agitator elements per fermenter was three for the standard disc agitator and two for the inclined-blade agitators.

By using the inventive inclined-blade agitator type 3, a markedly higher increase in k L a value could be achieved, compared with all other agitator systems used, not only with increasing speed of rotation but also with increasing gas-introduction rate.

The oxygen transport coefficient was determined by the saturation method. The inclined-blade agitator has primarily an axial transport direction with a radial component and therefore, achieves a highly effective mixing. It represents a series of agitator types which are often used in 2131. Read more about SIS Subscriptions. Company organization, management and quality.
