Problems solved by technology

This surface therefore limits the upper limit of the fermentation ratio
This disadvantage cannot be overcome by improving the hydrodynamic conditions in the fermenter, for example by improving the inflow of the hose when increasing the stirring peripheral speed, due to the increased shear load and the additional diffusion resistance which cannot be influenced by the hydrodynamic forces

Embodiment Construction

[0069] For example, a hose module can be produced as follows:

[0070] Firstly, the coiled hoses are wound closely next to each other on parallel tracks with the same stress as possible on the coiled stator, which rotates as evenly as possible. The tension of the hose can be determined with suitable accuracy by the weight of the loose roller which is as stable as possible in height (acceleration force). The circumference of the coiled stator is dimensioned in such a way that it corresponds to the length of the tensioned hose module plus waste loss. The size of the scrap loss is mainly caused by the stress difference when the hose is wound on the winding stator, and it is between 10% and 30% according to the uniformity of the winding. After winding, the hose is connected to a thin silicone rubber strip with a thickness of 1-5 mm and a width of about 5-20 mm. The coating of such strips can be done with a doctor blade without great precision requirements. Use this scraper to s...

Abstract

The present invention relates to a device and the use of the device for the gas treatment of liquid media. The device is composed of a support adjusting air supply and discharge, and at least one tube module. The tube module is composed of a plurality of tube segments in parallel and assembled in head support and feet support, and is connected to the support. The support is a stator. The stator is provided with an upper air supply device and air discharge device and an opposite turning device used for turning the tubes.

Description

[0001] This application is a divisional application of the invention patent application with the title of "Module for Membrane Ventilation", the filing date is October 25, 2006, and the application number is 200680041491.8. technical field [0002] The invention relates to a device and its use for venting a fluid medium. Background technique [0003] In the pharmaceutical industry, the manufacture of recombinant proteins plays an increasing role. Because of its ability to produce hyperglycosylated proteins with post-transition modifications, it pioneered animal cell culture for the production of more complex proteins. [0004] Usually, in order to provide oxygen to microorganisms, the dense air bubbles of the stirring mechanism with dispersing function are used. [0005] Animal cells place special demands on the technical reactors in which the cell culture takes place. In particular, high shear forces, such as those required to break up air bubbles, are to be avoided, sinc...
